Pa 4000

Fireman99

Would the PA4000 (h/k) 100w /ch x4 be enough power for my RTI 150's?
I would hook this up like a Bi Amp
1ch LF High
1ch LF Low
1ch RF High
1ch RF Low
for a total of 200 w going to the left ch and 200 to the right ch

Edit pls disregard this post am a little confused the PA 4000 will not do what I was informed I was just looking atr it and it will only do 2 ch X 100w and that is less power then I's giving them now.
Gona go back and look at a Parasound amp 5 x 140w/ch
more power the better

just to set you straight:
PA2000 - 4 x 45 or 2 x 100

PA4000 - 8 x 45 or 4 x 100

(all into 8 ohms)

Unless you are getting some good deal on it though, I think you can find a better value in amplifiers.

Thanx Cre I must have looked at the 2000 instead of the 4000.
Question still is then would the 100w highpass left,100w low pass left, 100w highpass right, 100w lowpass right. Be a significant power improvement for my 150's?

Couldn't tell you. If you are dead set on H/K then pick up a PA4000 from someplace you can return it to. Listen for a week or two and then make a decision.

F99, that would work, and I believe that it would drive the 150s OK. I run mine bi-amped with a 200 watt Adcom 5500 driving the woofs, and a 125 watt per Adcom 5400 driving the tweets/mids, and really, when you think about it, I'm only gaining maybe about a 3 db increase in headroom on the woofs than what the HK 4000 would be. The increase I see on the tweets/mids would be negligible.
I say go for it.


Make sure first though that you can't get two 2000s cheaper than 1 4000. You should be able to get 2000s for just a little over $200 shipped. IMHO, this is the best amp value on the market today.

thanx big I'm in Canada though I can get the 4000 for a bout the cost of 1 1/2 of the 2000 it would be my cheaper option i looked into the 2000 as well.
Now the Question is would I benifit more from the Parasound 5 x 140 w amp and run the same configuration and use the 5th chanel to drive the center ch? The Parasound is a little more then double the cost of the 4000 at the same store ( and Para has a 10 and 5 warranty)

Well F99, only you can really answer that question. Is the Parasound a better amp? I say probably so, if not definitely so. Is it worth over double the cost though? I say no. Think about it, if you bi-amp your main 150s with the Parasound, you would be getting 80 more watts per channel, which would give you less than 1.5 DB more headroom per speaker. While more power is always a good thing, that would not really be a very noticeable difference (if you could tell it at all), and not worth double the price, IMHO. But that is up to you to decide. Plus, with the Parasound, as you've already pointed out, you can use that 5th channel for your center.

Good luck whichever way you go, and let us know what you do. Really, you just about can't go wrong either way though. It's a win, win situation.

This is true I think I'm gona talk the the audio store here and see if I can bring in the 150's and hook em up to the parasound and see how it performs. unfortunatly he doesnt have the 4000 in stock to compare to He would just order it in.

However I may just go with the 4000 for now to drive the fronts and add another amp after x-mas (when the wife gets my RTI4's for me) and move the 4000 to them and a multi room speaker deal (2x100W rear surround and 4 x45w for my outdoor speakers)

That is true, the HK4000 will give you a lot more versatility and flexibility than the Parasound as far as mutiple zones, etc. Plus, you could always add a 2000 later if need be for either bi-amping mains or 7.1 rear channel speakers, and the 4000/2000 amps would tonally and sonically match your 8000 receiver's sonic signature perfectly.
