Well he's trying to change my mind into buying "his sub". Got his info from ram-designs. Trying to get a custom box built so when i buy the bl. This is part of emails back n forth:
basicly my sub like small sealed and ported boxes...smaller ported box than the fi bl12..and my 12 dont cost as much and handle the same or a tad more power..now as far as the muddy bass u might have heard..that from the box itself...the tight clean sounding bass is again depending on the box...now i can tell u this much..if u build a box for the fi bl 12 and lets say u do there smallest size ported box which is 1.8 cubes..and lets say we tune it to 33hz...if u put 1000watts to the fi bl and then take it out and put my sub in..my sub will be louder an the lows will pick up alot...its been done already thats how i know...u have a couple fi nuthuggers in the 5 boros and when some saw the test...they sold there fi and went with my subs....
