Well, now that I am in Germany I have to figure out some amplification for my XXXs. I left the Peavey 2600s back in the states because they were 120V models and I really didn't feel like coblling up the transformer leads to change them over to 230V.... Also, while good amplifiers, they had loud ass fans and did not really make as much power as I think they should. Anyway, now I have to decide on what to buy. I was looking at a pair of the 1000 watt Dayton rack mount subwoofer amplifiers, a pair of them would be pretty cheap and they have selectable input voltage, 120/240 volt, so they would work fine. My only thought is, they just might not be enough power, and I am not really convinced they are 1000 watts RMS each, even if they are, that still might not be enough.... I am not 100% sure of this, I still might choose them... But, I also found a proaudio amp from Crown that really looks nice. It is the XTI400, it is about 1200 watts RMS per channel @ 4 ohms, it has a switchmode multi-voltage supply also, so I can plug it in pretty much anywhere in the world, and has onboard DSP features like crossovers and EQ and has a variable speed cooling system that is supposedly inaudible at lower playback and heat levels.... It also weighs about 18 pounds... But, it is expensive, retail is about $1600, I have found it online for as low as $800, Parts express has it for $960, or about $1000 with shipping...
Anyone else have any other thoughts?
Buying anything over here from the states in a local shop is very expensive, so forget that...

Here I am ....Here I am mufuker...reading your shitty thread....reading away....every fuckin letter I read....
Solution....... Buy shitty cheapo amp there at German Pawn Shop....and goose that bitch with military hardware....
I'm screwing with you... I got a good friend in the UK that might be able to help. I sent him an email a few minutes ago...i'll let you know.

OK, back on subject..
Well I ordered a sub amp, actually bought one on Audiogon... I decided to go with a different approach than the PA amp. I purchased an Acurus A250 (350 wpc @ 4 ohms at like .008 THD)... I know this is a lot less power than I originally had, but, I think it will work good and sound a hell of a lot better. This amp (the version I bought) sold for about $1200 5 or 6 years ago, I have seen a bunch on ebay go for the $4-600 range. This one was pristine, the guy wanted $500, I offered $350 and he took it.
Also, I hooked up the towers on my solid state home built amp... OMFG BASS! This house was bred for bass.... Honestly, they have plenty of bass by themselves, ridiculously good sounding bass, these concrete walls really do the trick.... That is why I think 350 watts per sub will be just fine for now... If it isn't enough power I will retire it to bedroom or garage duty, but I don't think that will be the case....

Acurus lines were sold through Klipsch with some of the more modern line of speakers for 2 channel or HT.
I never heard one......The newer lines of Klipsch can be bright as hell with mediocre SS receivers. So I would think these amps are voiced a little more mellow to chill out the hot top end...that's a guess....
You may want to try it on your main towers to see how it fares. It should be a rather clean sounding subwoofer amp, nonetheless.
You may still have some headroom for a good peak or transient from a movie or whatever.
It would seem those big 18's could just lope along at idle and still mow you down when required. I dunno....
I remember when the local audio buddy Dan came across various SS power amps. He had a nice Phillips lab series power amp once or the like, 400 watts or something.
"Gee Dan, that would be a rather nice subwoofer amp for my SVS toilet paper tube slopwoofers, you wanna sell it to me?"
That almost pissed him off. "You ain't gonna waste a nice amp like this on any subwoofers.....grumble..grumble.....you can get on eBay and bid for it if you want to do that..."
Really, he needed the cash, and knew I didn't have it....

Yes, the Acurus was one supposedly one of the best sounding solid state amps for around $1000 at the time, I listened to them when they and the Aragon 8008 first came out... They were good sounding units. The Aragon was pricer, sounded a tad better but had lower power, the Acurus had a little more balls I guess was the best way to put it. 350wrms per channel is still pretty healthy though...
I really think it will be fine though. I'm not sure if you were around then, but my first amp on the Tumults was a 350WPC Altec Lansing, that same amp almost destroyed my Maelstrom 18. When I upgraded to the pair of 2.6Kw Peaveys, it was louder, but not really a whole lot louder, surprisingly.... The Tumults would still get way to loud off the Altec, in my paper wall trailer. The XXX18s are even more efficient than the Tumults were, so I think this will work out great.
Thing is, lately, I really have been regretting the dual 2ohm coils on the subs. I had them built that way to extract maximum power out of pro audio amplifiers.... They really aren't suited for home audio amplifiers if you want to run one amp per sub. I wish I would have bought dual 4 ohm coil subs, then I could run a pair of almost any decent SS home amps on them, like a pair of a250s or GFA555s.... You know what I mean?
Still, I think this will work just fine, and probably add 10 years of life to the XXXs.... The room I have now is so awesome for bass, that if they are lacking, I'll probably never notice....

I just turned on my SVS subs. They are 4 ohms, connected in stereo with roughly 60 watts per side. Plenty loud enough for me. I live in a crummy trailer, however.
The combination of Lascala and SVS when cranked up bit puts the whole place into resonant convulsions. About 2-3 watts on the mains, and maybe 20 on the subwoofers.....
I didn't think the SVS subwoofers would blend very well with the horn bass. It doesn't really seem that bad. I have the subs set at 40Hz and down.
Once of these days I'll get a better amp.

Well I fired it up for the first time last night. I think that amp will be OK here. I definetely lost a little headroom, but it will still get plenty loud. The XXX laugh at 350 watts..... I will do some more listening this weekend and give my impressions. It is nice not having the fans, and I can best describe the sound as very clean so far.....

OK, so I have been listening to this for about a month now.
The sound is fantastic coming out of that amp. I definetly sounds better than it did with the Peaveys, but I have to be carefull saying that being in a totally different house.... Regaurdless, the sound is very, very good. The amp runs relitively cool, I haven't really given it a workout yet like I would give the Peaveys back in the day...
One the other hand, I really do miss the headroom and sheer output of 5Kw. The 400 wpc right now isn't all that much less, it just isn't exactly what I had hoped for....
Sooooo, I think I may have a solution.... My XXX are dual 2 ohm, so that precludes running most home amps.... But, I really would like to double my power, but stick with the home amps... So here is my idea... I think I will buy an additional a250, so I have twice the power, and either see if I can change the primary winding to drop the rail voltage about 10-15% so it won't exceed the current limitations of the output stage at 2 ohms per channel, or just buy a set of new power trannies (Maybe $90-100 each for 1kw toroids) with secondary voltage about 10-15% lower than what is in it now. That way I would have a pair of 800-900 watt ampliers that should be able to handle 2 ohms per channel, we'll see, I still have alot of thinking to do....
I just have a big space in my equipment rack right now begging to be filled with another amp....

Will you have any issues with the protection circuits in the amplifier, from dropping the rail voltage? I don't know how the hell they go about it....... But isn't there a circuit for when the amp draws too much current and shuts itself down? I guess proctection circuits can be defeated.

That is one of my concerns....
BUT, I just found out that I can get dual 4 ohm recones, so that might be a smarter way to go about it really....
We'll see what happens, I'm really not in a big hurry right now anyway....
