>>Am I reading it wrong or does that 240 only have 50W per channel? Doesnt that seem a little low for a $600 reciever?

HK receivers are rated "all channels driven simultaneously, all frequencies" while most receivers are rated for 2 channels and often at 1 KHz. If you test any of the "more powerful" receivers under the same conditions you get about the same results. Here's an old, but interesting link :

HK is very concervative on their ratings. This actually is a good thing. Many receivers ratings are misleading, and are not full bandwidth rated. A 50watt/channel HK will blow the doors off of most 100+ rated no name brands.

Wolf, welcome. I took a look and at p.27 of the 240 manual you'll find a discussion of the "Quadruple" crossover provision which allows setting different crossover points for four different groups(mains, center, side surrounds, back surround)of speakers. This is a plus factor, but keep in mind that many Axiom users have found the typically suggested 80Hz crossover to work well for all speakers. You can experiment.

New, the 50 watt rating, as John pointed out, is with all channels driven. The rating shown for the more common(and more realistic for home use)two channels driven spec is 65 watts. In addition, HK conservatively takes the rating from a lower point on the distortion curve than the distortion percentage shown. The rating could probably be around 75 watts if this wasn't done. Amplifier power ratings are true, as the FTC regs require, and must show among other specs the bandwidth(generally shown as full 20-20KHz)and distortion max at power levels up to the maximum. Receiver/amp power ratings should be among the least of concerns in audio.

Thank you, everyone, for your help and advice. Going to email Axiom and see what they say re: which model to get based on my needs and room size.

Go with the 8's......I use them with my Ascend 170's in a 13'x 18' room, with a 65w x 3 channels driven Outlaw 1050 receiver and they sound fantastic! I'm only sitting 5-6' from each one and have no problems with too much oomph!!

Also, the crossover is globally set at 80hz and the 8's sound great with that.

I have no experience w/ the QS4s, but i can tell you that the speaker I am most impressed with from Axiom (that I own) are the QS8s.

They're GREAT surrounds.

Bridgman,

Maybe they are about to turn the 435 into a 440? That means close out on that model and $avings. Tempting.

Hi!
I'm sure you're not going to regret that extra $100, you'll be amazed by the results!

As you stated since $100 is not going to break the bank then why not get the best and be done with it. That's the logic I used when purchasing my speakers since I would always be wondering how the QS8's would sound if I bought the QS4's.
