Who makes the loudest speakers and sound system?

If you want the MOST POWER, there really are only a few names that come to mind for amplification.

Krell (www.krellonline.com) Named for the creatures in the movie "Forbidden Planet" because they had "unlimited power"

McIntosh Labs (www.mcintoshlabs.com) NOT affiliated with Macintosh Computers in ANY WAY (and that's a good thing!)

Speakers?

Martin Logan (www.martinlogan.com) Start about $600 a piece and go up to well over $10000 each

Sonus Faber (www.sonusfaber.com) Start around $1000 and race toward $20,000 a piece.

Wilson (www.wilsonaudio.com) basically, I will just mention 1 pair of their speakers can cost over $130,000

None of these are TRULY Top of the Line companies either, but the prices of the even higher end companies are stratospheric!!!

Hope these help! bose rocks i have one and my neighbors can hear it (they live about half a mile away from us) Ack, no Bose the others have been sold a bill of goods and they bought it, learn from their mistake and don't make it. Those in the business (home theater and stereo) and audiophiles avoid them like the plague, and I'm both.

Speakers that play really loud with reasonable sound quality and reasonable price (not cheap) have been mentioned, Cerwin Vega and Klipch for speakers, they are very efficient hence louder with less power. You could go for concert or club type speakers that are used for public events and concerts. There are many like Pevey.
