I would suggest that Fi BTL would be very tough and give about anything a run for its money... and slaughter many others. However, I am sure there are others out there to compare. Maybe our guys can make some suggestions.
somewhat musical, this is not an SPL burp monster, but this isn't someone who has any knowledge or regaurd for SQ either. He is new for the most part... ran Diamond Audio D1 12's prefab ported before and it made him happy. Now he wants "louder".good loud system, loud daily probably
oh yes, that's what I'm runnin Sonnie! I am trying to squeeze 4 of them into a van ported, but with 44"x44" just to mount the subs, that doesn't leave much for a large slot port. So I may only run 2 of them giving them more airspace and a very large port. But my buddy just wants loud, something he can beat up on and it keeps going... but you're right, I think 3-5 cubes @ 30-40Hz would be loud enough for him as well...Exodus has their new Mal-21 that is definitely not going to be a shy sub.
