but at that size, you can't go wrong with cerwin-vega

thanks benz
I'm thinking 1,000w @ 4 OHM ...
lol, trust me I've drooled over these...
I am building my own 18"... that's why I'm looking for what speakers are the best...
should I just snag one of those speakers in that dual rig?

if i had the money and the use for them, i would.
JBL is a highly trusted name in pro audio, like Marshall for guitar/bass guitar amps

So, I think I'm going to go with 18" Peavy Lo Rider speaker @ 8 OHM 800W.
03:43:30 ‹Rivea› 112 volts + and 112 volts -... total swing is 224 volts.
31/01/2011 03:43:38 ‹Rivea› P = V^2 * R
31/01/2011 03:44:07 ‹Rivea› 800 = V^2 * 8 (rms value of power and voltage)
31/01/2011 03:44:19 ‹Rivea› 6400 = V^2
31/01/2011 03:44:26 ‹Rivea› V = 80 volts RMS
31/01/2011 03:45:06 ‹Rivea› V (power supply ) = V * 1.4142 (square root of two) = 80 * 1.414 = 112 volts

The amplifier power is most likely limited by its power supply voltage. If it can deliver 400 watts into 4 ohms, it can deliver about the same voltage into an 8 ohm load before the output transistors saturate.
Therefore the total power it can deliver into 8 ohms will be about half of that delivered into 4 ohms. I'd estimate that you'll get 200 watts out of the amp into 8 ohms.

House... speaking of old school, I forgot to mention during our chat. I like my JBLs. I use a couple of E140 woofers in full size reflex cabinet tuned to the resonant frequency of the E140s, some 2370 biradial horns, and slotted diffraction tweeters. The setup is bi-amplified and I use a DBX electronic crossover to split 800 Hz and below to the E140's and 800Hz and above the the horns and tweeters using 200 watts RMS per channel, 4 channels to drive both sides. It is marvelous for my home theater front channel. It sounds like a live band in the house if I put on good CD or wave file. I built up the system myself when I lived in 2000 square foot ware house quite a few years back.
The E140's are wound in 4 ohm voice coils so that my ADDCO (an old brand ) amps can deliver their full power into the woofers... It is expensive to find an amp capable of driving 800 watts into 8 ohms unless it is a stereo amp that is bridged.... like we discussed.
