Audio pulse, RE audio XXX or Suggested Sub for home theater?

Ok, the i understand exactly what you want. look into a soundsplinter rl-p 18. They are $420 a peice. So you could get two for the price of one of the others. Now i did notice that the two subs you were looking at were mostly for SQ. This one is SQ but it is loud as hell. It has an Fs of 20.71Hz for the dual 2 ohm 18" and 21.5Hz for the dual 4 ohm 18". So this sub is meant for the low lows lol. I sent them an e-mail and got a response quick, good customer service and a great product, what more do you want? Anyways, i too am buying one of these subwoofers for my home theatre set up. In the e-mail i sent him i asked what about what kind of box he would recommend, and he said that 1 18" rl-p would love a 18 cu ft box tuned to 14Hz(in the e-mail he says this will be the optimal enclosure for this driver), so you 30-40Hz will be nothing, you will have clean loud response down to ~10Hz(Fathom cannot top that, and this one will do it louder and just as clean, if not cleaner,this is also where the crazy shaking comes in), can't bet that for $420. This sub is amazing. Now just imagine two of them in two separate 18 cu ft boxes, WOW. You will make the gotham sound like crap then, and be louder, and you will have saved $11,580. If you need a smaller box cause i know 18 cu ft is huge, then he recommended 12.8 cu ft at 18Hz. Well i hope this has helped you, take my advice and buy the rl-p, you WILL NOT be disapointed, but your freind will be beggin for trades. lol
