Top Form! Marten Design Form Tower Speakers.

Beautifully "Form" follows function! Review sample in snow white paint scheme.

I've heard this pair of speakers on more than a few occasions in the Audiomatic showroom at Amcorp Mall. Usually partnered with either Vitus or Bladelius amps, they had a really pristine clarity, open and refined quality that is hard to describe with words. I requested them for a review , Eugene agreed.

The foot print, with out riggers attached for greater stability and note the floor firing bass port(bigger black hole) on the left. Also note the cramped speaker cable binding post. Too tight for spades, but just nice for banana plug terminated cables.

The Marten Design Form series are designed with dual function in mind, to serve as quality stereo and part of an AV system. The triangular shape of the speakers are form follows function, to eliminate internal standing waves behind the 7" ceramic woofer, which I believe is sourced from Accuton. The tweeter used is the ribbon type for high end refinement. The custom automotive grade white paint job on the review sample was faultless and very brilliantly smooth polished. Other finishes also available on request. The speakers rest on 3 extended out riggers made of aluminium and finished with rounded tip spikes to protect floors and allow easy maneuvering of the speakers. There's a floor firing port right next to the speaker terminals in which I found too cluttered for use with my spade terminated Siltech Classic Anniversary 330L series speaker cables. Banana plugs seems to be the only practical option. I was forced to use one of my older banana plug terminated vdH CS-122 speaker cables for this review instead. I know, I know, they are not as transparent or as good as the Siltechs, so do note this in to consideration when reading the following sound description of the Marten Form.

The rounded floor spikes for easy maneuvering and floor protection.

I played around with the speaker placement but found that this speaker to produce very hefty bass quantity. In larger rooms, they'd be fine, but in my small 32 cubic capacity volume room, the bass just over whelms all the other frequency spectrum of the music reproduction. I had to make a foam bung to plug the floor firing bass port, resulted in a very controlled bass, and much more even tonality. This is no fault of the speakers but rather, the room mode doing it's thing again here. I then proceeded to play with speaker placement again and eventually settled for 40 inches from speaker back wall and 18 inches from the side wall, measured from the tip point at the back of the triangular speaker box. All listening test was done without the speaker grilles. I also experimented with toe in, but much preferred the speakers just firing straight a head in to the room.

The highly refined ribbon tweeter mated to the ultra quick response Accuton supplied ceramic 7" woofer.

The first thing that struck me with these speakers is the clarity, pristine and refined airy quality of the high frequency presentation, making the harpsichord and that triangle ring sound so.... very natural! The mids are open and very clear. The lower mids are very much fleshed out, giving male vocals more solid chest feeling, which is a good thing. This slightly fleshed out lower mids also contributed to most classical instruments like oboe, woodwinds, flute, violin, viola, cello, bassoon and contra bass, making them sound very lush and woody realistic indeed. Classical fans, rejoice! The bass, though handicapped by the foam plugged in to the floor firing port, is still tuneful and very accurate, if did not extend any lower then say, 35Hz or so in my room, perhaps due to the foam plug in the bass port.

The triangular box shape, very un usual.

The staging is wide open and depth perception is rather good. Way, way better than my own Audio Physic Spark can do. This is a very transparent speaker, despite being handicapped, again by the use of a budget speaker cable. Musical details are still very much audible and one doesn't really need to look out for them, they are just laid out naturally within the sound stage presentation. The driver coherence is pretty spot on, which is normally hard to achieve given the difficult design spec of using a ribbon tweeter mated with a dynamic cone. I could stand up walk around in front of the speakers without the sound stage collapsing, which is proof of excellent driver integration.

Micro dynamics is a little compromised some what, like for example, high hats. In a realistic reproduction, one should hear the stick clearly hitting the brass, followed by the long sustaining decay, slowly vanishing in to thin air of nothing ness. But with the Marten Form, the initial stick attack of hitting the brass seems to be slightly subdued, like as if the drummer is holding back, however, to it's credit, the long sustaining decay slowly vanishing in to thin air of nothing ness is fully reproduced with no problems. This characteristic, I feel affects a few other instruments too, like classical guitar, piano and Chinese classical instruments like guzheng and pipa. Rock music can also sound a little too refined and polite, lacking in just that bit of edginess and bite that makes rock, well, rock! Again, I am mostly nit picking here, because that certainly didn't stop me from enjoyinging to one of my all time favorite rock recording on CD called, Amused To Death, by Roger Waters, a member of Pink Floyd doing his solo thang!

I was certain closed to being amused to death by the Marten Design Form Tower speakers.

This is quite an amazing studio recording with special effects thrown in to the disillusioned musical poetry mix for good measure. In scenes like TV preaching man sounds from the opening track, What God Wants, is realistically reproduced. The Marten Form's AV abilities are put to good use here with dogs seemingly barking behind the left side of listener position, planes crashing dead center of sound stage, panning in from the right side behaind my shoulder! Whoa.... this is surreal indeed. I know we are talking about stereo here and not multi chanel surround, but this CD, when played in a well optimised system can do just that. Now go buy this CD, if your system cannot project the effects of what I've just described, you need to keep working on improving your hifi. It's certainly not optimised yet!

The rear tip point. Note the smooth paint finish.

Macro dynamics is however a very strong point of the Marten Design Form. I have no problems swinging very high peaks during orchestral crescendos at very high volumes. In fact with some music, life only starts after 90dbs or so, figuratively speaking! Like when I was playing Flamenco by Pepe Romero. The louder I went, the better the music sounded. Perhaps it's an early symptom of me losing my hearing? Go figure. He!He!

Another issue I noticed when the Marten Form was playing in my room was that it tended to sound a little on the dark side, a thread I never noticed when auditioning them in Audiomatic's showroom. Perhaps the Marten was revealing the dark chocolate like tonal presentation of the Pass Aleph 0 and the Torus Power? The back ground silence was exceptional though, so no complains from me on this area.

The Marten Design Form Tower speakers in my room, standing very nearly 4ft tall.

Overall, the Marten Design Form is a superb audiophile speaker as much as it's potential as an AV capable speaker. At RM$24k, it's certainly not cheap, but look beyond the price, instead a glance the design philosophy, build and sound quality will convince you that pride of owner ship is totally worth your purchase consideration, if you're in the market for a pair of speakers at this price point. I know, because I am considering too, just in case Santa is smiling upon me this year!

Aural Realm, Auralex MetroFusor Diffuser Panels.

Auralex MetroFusor diffuser panel. Moulded from humble foam!

Did you know that, in room treatment, other than the first reflection points at both the side walls next to the speakers, the back wall to the throne is next most effective area to apply treatment?

There are 2 ways to treat the back wall. Some say the back wall to throne a.k.a. "sweet spot" should be total absorption.

My previously installed full absorption back wall treatment from the throne.

Some time ago, I started to treat my back wall to the throne, by having 3 absorption panels lined the back wall. The idea was that there is less back wall sound reflection, which can effect the imaging focus quality within the perceived sound stage. Once I did that, I could hear more focused imaging quality, less high mid sibilants and an overall quieter musical noise floor. Listening to my hifi system became more rewarding sonically and less distracting, leading to a more enjoy able aural experience.

Lately, I have heard another group proposing to use a combo of absorption and diffuser treatment for the back wall to the throne. The argument is that the combo treatment will yield a more "live" like hall/studio acoustic environment. There is more airiness to the sound stage, so to speak.

Armed with this latest thinking, I asked Sky Wong of Centre Circle Audio to loan me 2 pcs of 2 x 2ft foam diffuser panels called MetroFusor Diffuser, manufactured by Auralex. They have some fancier diffuser designs fashioned out of wood squares called SpaceArray, but those proved too costly for my measly budget.

The 2 side absorption panels replaced by the Auralex MetroFusor foam panels for initial sound trials.

I went home, and immediately started work on the back wall. I pulled down 2 side mounted absorption panels of the existing treatment leaving only the middle absorption panel on the wall. I then proceeded to stick on the Auralex MetroFusor diffuser panels to replace both the side panels. The Auralex panels are very light weight and easy to work with.

I then proceeded to play some music and I noticed some improvement to the perception of sound staging depth. with the deeper, airier sound stage, the images of vocalist and instrument gained an aura of air around them, making each instrument behind the vocalist, that very bit more realistic. With CDs that are well recorded with hall ambiance, like the ever green Harry Belafonte, Live at Carnegie Hall, I noticed the biggest sonic pay off. Hall reverbs are now un-truncated and hand claps in between the songs seems more "alive" and the whole experience of listening to the CD is more 3D projected than before. It seems that bit of reverb sound deflected off the diffuser panels just behind our ears, can contribute so much to a more realistic concert like aural experience.

Encouraged by the Auralex experiment, I then think that, what if I could do another DIY diffuser(like my earlier shoe rack project on the speaker's back wall which turned out pretty well), say like hanging some DIY CD racks on the back wall, where both the current diffuser panels now reside, as I could use some extra CD storage space too. As some may say anything that is not a flat surface can be used as a diffuser panel. I went to Jusco Department store and found a DIY assembly required wooden CD rack, about the size of the diffuser panels. I bought 2 sets for about RM$30 each. I carefully assembled the two CD racks with the help of my little girls. DIY audio can help to unite the family too, who knows?

The cheaper, but less sonically effective alternative, DIY CD racks(the black ones on both sides the absorption panel), available from Jusco Departmental Stores.

Once assembly is completed, I proceeded to replace both the Auralex diffuser panels with the CD racks. I then proceeded to play the same Harry Belafonte CD again. This time I have found the hall ambiance of Carnegie Hall to have suffered and sounding slightly compressed instead. Having said that, some diffusion is still some what better than all absorption only. I also found some of that high mid sibilants resurfacing again, even though just barely. The CD racks are more practical, as they can hold another 50 pcs of CDs or so, but for me sonically and aurally, they just didn't do enough. At least, not after hearing what the "real deal", purpose designed Auralex MetroFusor diffuser panels are capable of anyway.

The Auralex panels went back on to the back wall of the throne. For permanent installation, I sprayed the Auralex panels with matching grey coloured spray paint, to suit the over all peach/grey paint scheme of my listening room.

Note: For those intending to spray paint their foam panels after reading this. You need to know that spray paints contain solvents, which can melt the foam panels, if paint is applied excessively at once. It is also very important to do the spray work out doors, if possible. Other wise, do so in a well ventilated place, for health reasons, wear a face mask. When spraying, first apply as thin a coat as evenly as possible. Then wait for the painted panel to cure, about 20-30 minutes is all it needs on a sunny day. Repeat this two steps several times, i.e. apply several thin coats, each time allowing the panel to cure before proceeding with the next coat. If you observed the above spray painting instruction, you should have a very uniform coating of any colour you choose, with very professional looking results.

The finished project, in matching grey paint scheme!

Retailing at RM$110.00 per panel, these Auralex MetroFusor diffuser panels are a bargain, if used correctly to achieve great aural results. Needless to say, I bought the review samples, and are now a permanent part of my room treatment system.

November Suprises!



Well from the humour above, hopefully it has nothing, what so ever to do with the hifi equipments in your hands. He!He!

This month will see us playing with a few things certain with a few surprises in store during the month. Just like last month's un announced arrival in the form of the wonderfully musical Pathos Endorfin top range CD player.

Speaking of "form", we also have a pair of Marten Design Form Tower speakers on review. It's quite a knock out too!

Whilst still on the subject of speakers, I'll try and have a go at one of the "big bad boy" of PMC, called OB1(Kenobi of Star Wars, remember? , sorry, I just can't resist that!)i. It's quite possibly the largest speaker to enter service in my tiny 32 meter squared capacity room, but James of AV Designs is pretty confident that the PMC OB1i will perform well.

We also have the first ever Chinese made Krell, no, not those Jungson amps but the real deal in the form of S-300i integrated amp. This Krell also has i Pod connectivity too, cool!
Also latest from Esoteric, we test drive the newly arrive stereo SA-50 CD/SACD player.

Now, how can we, the self proclaimed cable guys not have any cables to play? Well, fret not. We play with another member of the Siltech Classic Anniversary series, the SPX-300 power cord.

We also have some budget hifi nuggets for those who just wants some nice, effective tweaks to play with. We have Auralex foam diffuser panels and some Cardas Golden Cuboids tweaks on trial.

We may also test drive a few other un announced surprises too!

Stay tuned.

Love On Parade


This is unprecedented!

Maggielurva has just informed me and Big E that he would like to organize a listening party for his new album "Love's Tapestry" featuring Roger Wang and Gina Panizales, at CMY Damansara Utama! The time line would be the first week of December.

He said he needs to work out the details and logistics with CMY, but basically guests (and readers here) would get a chance to listen, first hand, to the "master" tape mastered by Doug Sax! Gee, how often do we audiophiles get to experience this in the local context? Kudos to Maggie for his generosity!

Stay tuned for more updates in this blog!
