The Giant Subs

Subwoofer or subs which most audio enthusiast will called. Everyone who into home theater or Hifi will not need introduction to a sub. Is a boom box so to called it. I am going to focus on this sub in a home theater setup. I call this sub a monster that I have recently change to. This sub which is non other than the JL Audio F212 V2 dual drivers subwoofer. 

The subs as from the picture is quite a tall subwoofer standing at 81cm, is like half size floor stander speaker. It also weight 102 kg. This is good enough reason to called it a monster sub. Each of the driver is a 12 inches ultra long throw W7 drivers. The power is 3600 watts RMS for this beast. It have both balanced ((XLR/TRS Combo) and unbalanced connections.

From the front panels left to right , power switch, daro connection, room optimzation (demo, defeat, calibrate). 2 LED indicators (Master/Slave), level mode, master volume, lights dim, low pass filter, trim, phase and polarity. This features are handy for calibration.

This are some of the accessories included in the box. One pair of gloves, the calibration mic and 4 pieces of sliders. This is very useful tool. It is use to slide under the foot of the subwoofer to allow easier moving of the sub sliding on the floor. I cannot imagine carrying this 102kg moving about in the room. I will give an extra point to JL Audio on this small accessory which is a big help.

A picture for comparison a floor stander speaker to the subwoofer. One good thing about having a sub like this is saving some floor space. Is like having 2 subs stack up. Thinking back before I was having 2 large SVS subwoofers is really taking up lots of floor space. This is a positive point for me. 

Digital Automatic Room Optimization (D.A.R.O.) system as the name suggest is a build in auto calibration on the subwoofer. I will describe as similar to how a mic is connected to an AVR and run the auto calibration. Basically is the same but this is done specific for bass management. As this is setup for home theater purpose, after running the DARO will than run the auto calibration in the AVR as follow up to complete the setup.

This is the graph from REW on the bass response. Blue line is the before applying any EQ to it. The redline is with EQ to flatten it. This is pretty amazing given the fact that this is just 1 subwoofer vs previously of dual SVS ultra subwoofers. Now the movie experience is with "kick". The bass slam is pretty real right smack to the viewer. Totally enjoying it.
