I have 2, NAD S200 amps in bridged mode, and they can
easily give you 1400 wats in 4 ohm ! They are 30 kilo beasts!

What do you power with ?

In my music set up I use a Hafler 9505 which is 250wpc 8 ohms but in my dual 2235Hs it is rated 375wpc 4 ohms. It has plenty of power and control. They claim a damping factor of 1000.

In my home theater set up I am using a JBL MPA600. It puts out over 600wpc into 4 ohms and on movie soundtracks with deep bass explosions etc. the clip indicators will start to lightly flicker if I am a little above THX reference, which does sound awesome!

Amp...Altec 9440A.... that has been overhauled by Ira of IRATEC PRO AUDIO REPAIR. They were destined for the trash pile when I rescued them from a hotel.
Sub...Contra Bass.

I use nothing fancy just the Parts Express plate amps rated at 175W into 8 ohms. I have one per box to drive my LE-14A's. They sound much better than my AR 12" HT sub. Looks like I will build a 3 rd LE-14A sub for LFE to replace the HT sub. One of these days;)

BGW 750 can handle 4-15" drivers where other "higher" powered amps give out. They have stiff power supplies....large power transformer, and large filter caps with enough output transistors to allow 2 ohm loads with good smooth clean sound.

I use for my HT system a 18 "2240 h , in a ported box. Amplifier is a monoral DENON POA 4400 Model. The loudspeaker do not need more power ( 150 W) , but i am a little suspicious with deep bass response of this kind of "MidFi" and commercial amplifier....

I hope Audio research or Krell models shall be better...

QSC PLX 2402 (would like to have a 3402)
STEREO MODE, Both Channels Driven
8 ohms 20 Hz-20 kHz 0.03% 425W
4 ohms 20 Hz-20 kHz 0.05% THD 700W
2 ohms 1 kHz 1% THD 1200W

Crest 9001s for the loud stuff.Its the real deal!!.A casual rating of 3300 watts a side at 2 ohms for a stereo total of 6600 watts. BGWs amplifiers are not bad either.At the other end of my listening spectrum ,the Hartsfields get a massive 3 watts of single ended power to each cabinet running in full range mode.

3300 watts, that is alot of power!
i then think you are the most powered audiophile
in the whole world!!

It is/was certainly big and loud.

For my larger systems I use two Crown MA3600vz, 1600 watts at 4 ohms per channel. For my small system a QSC Power Light 236,
1100 watts at 4 ohms per channel.
These are used in a medium sized PA system.

It seems it not unusual to drive with PA-amps,
the only drawback must be that some of them
makes noise and has a FAN that buuzzesszz :rolleyes:

Though there are PA -amps that are as good as many
high end, OR better..

The Crown and QSC are GREAT i think.

Crowns make great sub bass!

Hey all!

Been real busy with the biz and haven't been able to visit as often as I would like.

I need to give special thanks to Don McRitchie for helping me get my "JBL Dog" handle back. Someone else had gotten it before I did and it left me in a mild state of depression. Since the person didn't complete the final phase of registration, Don cancelled his membership and I got it back!! :cool:

Back to good sub amps. Most of what I use are professional series amps. I have a set of AS2215's (dual JBL 2226J's in an SR series style cabinet) that I got in the tent sale awhile back. I'm running a QSC MX3000a bridged that delivers 3200 watts into the pair of AS2215's. I have them crossed at 80hz using an old 5234 active crossover. SUH-WEEEEET!! :D

mikebake: I have a few of the PLX3402's. They're nice amps, but they don't have the"gusto" of the MX3000a. The Crown Macrotech series kicks butt also!

This message comes from JBL Dog :cool:

Yes they do! but they like a good source for AC power,
I run each one it's own 30amp breaker off of my power
The QSC PL236's work very well and my back likes them to!
They are also more efficient when it comes to AC power.

All of my mids and highs are powered with the QSC PL2 series.

But as long as you have GOOD ac and enough of it, crown bass punches like NO OTHER!

The ONLY other amps for sub bass that moves your bowels is BGW! However, BGW is a rounder, warmer, heavier sound that is great, but isnt quite as aggressive as the crowns!

Its a matter of preference! I love both!

You've never heard a Citation XX then ;)

In my experience BGW and Crown rule! However, there can be other brands that Im not familiar with that produce great results!

As far as Crest, Crown, BGW, Bryston, QSC, Stewart, and AB I like Crown and BGW the best for bass!
