CSI5 and Amp
Hi Guys,
Well I pulled the trigger and finally got a CSi5 for my setup. I have an HK 354 that produces 75w x7 (525w total). I wanted to know if I need an external amp to power it, since its only getting 75w? My setup is:
HK 354
FRONTS: 2 x RTi10 Powered off an Adcom GFA-555 AMP
REARS: 2 x RTi6
SUB: PSW10
Also, if my fronts are powered off an external amp, does that mean that my center and rears get more than 75w, ie 525w/ 3 speakers= 175w per speaker? Thanks!

It will still supply 75 watts per channel. It does not increase wattage from channels that aren't being used to ones that are being used by the receiver/ amp. Each channel has it's own discrete amp. -
Thanks. Then Im guessing that the CSi5 is just as power hungry as the RTi10s. Any amp preferable with this setup? I was thinking of either Outlaw or Emotiva. I prefer clarity and crisp audio if that makes a diff. Thanks!

Really depends on your room size if you need an amp for it. Try it without one first. My choice would be Emotiva simply for the best bang for the buck and owners seem to be happy with them. I have owned B&K, Krell, Yamaha, Hafler and Bryston amps but not the two you mentioned.

The HK will power your center fine, but you may have to match the gains with the 10's with the channel level adjustments. The rest of your speakers not using the Adcom amps power will benefit from having more current on hand from the receiver since it won't have to handle the 10's. Also look into upgrading the subwoofer, the PSW 10 isn't going to do much more than the 10's can.HT SYSTEM-

Thanks guys! Im still setting the center up... trying to find a decent bracket/ stand to mount it over the TV, Sony Rear Projection. Any ideas? Thanks again

It is a massive speaker to install over the TV on top of that, trying to angle it downward might be a bit tricky. How abou installing it under the tv- Wait I see you have a RPtv. I would agree with Tony, right now your rears are not asking for lots if any reserved power, most of your power and reserve will be for your centre. Use the calibration mic to assist you in setting up the speakers.
Is your TV not wide enough to sit the speaker on top and use the "kick stand" to angle it ? -
i wouldn't get an amp just for it. that is a good HK AVR. when driving only 3 speakers, it probably put out more than 75wpc, but not anywhere near 175 as you expected. HK amps are high current too. for normal home setup, we don't need more than 30 wpc, especially the csi5 has a sensitivity of 91db or something.

dont need amp just for the center, wont gain muchI have found that tube based computers provide the best sound quality. ENIAC and MANIAC I offer a smooth, well defined and articulated sound unmatched by the current silicon based CPUs.

Yes get an amp. A parasound hca 750a in mono mode would power that CSi5 quite well!!!
But in all seriousness, that is a really good AVR (I used to have the next step up AVR 745). I will say, however, that ever since I added a small sub to my center channel, I am continually blown away by how much bass comes through the center channel, especially on flicks like the dark knight. That little sub goes nuts! WAY more bass and overall sound coming through the center than the mains combined. Also, I did begin powering my front three externally when I had that HK, and as powerful as the AVR was the dialogue and everything else was cleaner, and bass was tighter after I added the amp.
So I would say listen for a while and see, but an amp would bring out the most in that center.Living Room 2.2: Usher BE-718 "tiny dancers"; Dual DIY Dayton audio RSS210HF-4 Subs with Dayton SPA-250 amps; Arcam SA30; Musical Fidelity A308; Sony UBP-x1000es

Tried it and it slides off to the back of the TV. Guess its too heavy! -
Im gonna try and have it setup this weekend, and play around with the settings. How is the best way to adjust the gains on the center to match my Fronts and Surrounds? The calibration mic that comes with the AVR? Also whats the best cross over freq for this center to handle- its currently set to 100hz, but lower should bring more mid and bass through.. thanks!!!
