Iv had this woofer for six months now. Gone through three boxes and to get the sound I wanted I have a 6 cube box with 64 inches of port tuned to 30 hrtz. It's loud deep and still hits clean. I also feel it would be a great sound quality sub if in a sealed box. Love it, powerfully low bass just wish I went with the re 5000 sted of the hifonics 2400 strictly cuz I feel it would produce better at 30 hrtz and under

They just dont know about this up here !!!! But i get mean mugs at the light because I raddle their cars. I love it hahahahahahahahaha!! If you in traffic with me in the next car im giving it to ya so stay home!!!!

Two.......TWO OH LAWD THIS SUB AINT NO JOKE CLEAN BASS IM DONE WIT SUBS THIS ALL I NEED (drops the mic!)

I just got mine in yesterday nd played it today nd dam that b1tch sounds good if u got the money get it its beautiful Ima try nd get another one soon thank u Sonic Electronix.

I have this sub hooked up to a planet audio 1900w x 1 mono block 1 ohm stable puts out 1700 RMS at 1ohm. hits vary hard!!!!!! Do not have something bad to say.. 500 for this sub is a good price. Hits like a w6 or w7 13'' but this is a 18''

i hook up one of these on the soundstream 3400.1 an it was louder than my 4 15 inch t2 on my bd 4000 i would recommend this sub to anyone who wants loud clear bass

Have two of dem n a burban...with a 5500/1D P.A. amp hitting dem with 3200 rms...an dam it took bout two months to break dem in properly...but gotta love old vega stroker pro design....fo a Tru bass freak...its great...gotta love dem...da price I paid fo dem I promised I would never tell...
