Listening to the Imposing Frank AB-2 Tower Sub Loudspeakers

Posted by Tan 

Our very own Malaysian hifi maven Frankie Voon, the head honcho of the Frank Acoustics outfit, rolled out his Frank AB-2 Tower Sub loudspeaker system in late 2020. I have always wanted to have a listen to these loudspeakers personally, but due to the ongoing COVID-19 situation then, I never had such an opportunity. Until recently that is. 

The owner of a Frank AB-2 Tower Sub installation invited a few of us for a visit to his home for a live listening session of his system. Finally my years-long wait was fulfilled.

When I first came across the Frank AB-2 Tower Sub system design, I was definitely impressed by its versatility. It is a pair of tower loudspeakers incorporating two 9in Scanspeak woofers per side. The towers are tall, at 6ft 6in (almost 2m), they are taller than any person I know (An audiophile friend of mine likes loudspeakers that are taller than him, these Frank AB-2 towers would surely fit the bill 😜). 

The Frank AB-2 has a built-in cavity at its mid-section for the owner to place a bookshelf loudspeaker of his choice (as seen in the photo above) to cover the mid and high frequencies. Frank Acoustics can also supply you with a pair of their monitors if you so preferred. 

A built in crossover routes the bass part of the audio signal to the woofers, and the mid and high to the bookshelf loudspeaker. You can also choose to run the bookshelf loudspeakers full range, i.e., not have the AB-2 crossover filtering out the bass frequencies to the bookshelf speakers, in which case the AB-2 would be adding bass on top of the bookshelf speakers to augment and extend their bass performance. There is also an ambiance tweeter at the back of the tower to convey the air in the recordings.   

The Frank AB-2 Tower Sub's height and size gives it an imposing presence in any mid to even large size listening room.  I bet any visitor would be mighty impressed seeing them in your listening room, I know they did that to me during my visit. 

"Wow, this is a big sound." that was the first thought that popped into my head at my first listen. Yes indeed, like its imposing stature, this Frank AB-2 based system conjured up a big sound, with a soundstage that covered wall to wall. I was surprised that having the mid and highs handled by a pair of bookshelf speakers but the bass played through the bass towers, it seemed to have freed up the sound tremendously. This loudspeaker system could play a volume level that would definitely stress almost all if not all bookshelf loudspeakers. This system also sounded dynamic, speed and attack were handled with aplomb. It was an exciting listen on drum and electronic music with lots of bass line. 

On the other hand, this system also showed a saturated and vivid tonal color, rather than the somewhat bleached tonality that plagued some modern HiFi equipment. Vocal, may it be male or female, was served very well. 

I believe the overall sound of a Frank AB-2 based system would be influenced by the bookshelf loudspeakers you choose to pair with the Frank AB-2, therein lies the versality of this design. You can retain the use of your favorite bookshelf speakers by incorporating them into the Frank AB-2. 

I am sure the Frank AB-2 Tower Sub approach would give you an excellent upgrade path if you are a bookshelf speaker user. Given how hifi equipment is priced nowadays, this is definitely a bang-for-the-buck upgrade too.
