Who makes the loudest speakers and sound system?

I want to buy the best and loudest sound system available, someone please help.

Best and loudest home theater? try JBL Sythesis. The prices start at $11,000 and go up from there. You'll also need a dedicated room and a few thousand dollars more for accessories and installation. The other guy that mentioned Krell is also on the right path. Krell makes the Master Reference Subwoofer that at 20Hz can hit 120dB. The only other subs that I know that can accomplish that feat are large, commercial units you might see at a large rock concert.

A little known fact: Audio Video systems can cost as little or as much as you can imagine. Just like some people drive a Kia and listen to Bose speakers, some people drive Ferraris and listen to Krell. Bose are pretty good

look up www.crutchfield.com These people are outstanding!!! Bose is crap.

Depending on your budget you can go very high. Mcintosh (not the computer company) Makes a set of speakers that are $28000 a pair, however they can make your ears bleed easily.

Bay Audio is a good middle of the road setup, they will run you 1500 to 3000 a pair

PSB are also very good and offer several options as far as price from $250 a pair to $2000 a pair.

However the speakers are only part of the equation, amplification is far more important. Onkyo, NAD, or Mcintosh are the only way to go for quality and power.

NONE OF THIS EQUIPMENT WILL BE AVAILABLE AT NON SPECIALTY RETAILERS. BEST BUY WILL NOT HAVE IT. Check online for closest retailer. The loudest and reasonable priced would be Cerwin Vega or Klipsch. Well, do you want LOUD? Or do you want Quality? These two features are not mutually exclusive, as a good sound system can be painfully loud, but a LOUD system rarely sounds good.
