speaker rating and amp output questions

post #1 of 15
Thread Starter 
I have an onkyo 705 receiver and it's hooked to a paradigm cc-350 center, paradigm mini monitors for fronts, and a pair of paradigm titans for the surrounds. The speakers are 8 ohm but on the receiver I can only set it to 4 ohm or 6 ohm.
Another thing is the mini monitors say 80 watt max and the titans say 60 watt max and I believe the receiver is 100 watts per channel. I know you can have pretty much any speaker and receiver together no matter the watts if you don't crank the volume but I listen to my music rather loud and I worry about blowing my speakers or clipping my amp. Also when I switch from 2ch stereo to all ch stereo my sub output doubles, I've checked the settings and nothing has changed.
I know it's allot of questions but I appreciate all the help.

I have an Onkyo Paradigm combo myself and might be able to shed a little light. Firstly, you can set the receiver on the 6 ohm setting which is for 6 and up ohm speakers. You are right in assuming the speaker rating isn't a hard rule. You will be fine as long as you don't make the receiver distort(clipping) which can damage speakers. Those little speakers can only go so loud, you actually sound like a candidate for an amplifier, since your 705 has amp connections (pre-outs) but that's another topic.

As for the sub, with 2 channel mode are you in pure mode or stereo mode? Pure mode has no output to the sub, just the 2 speakers. Or perhaps you have your speakers set to large instead of small?

Thanks for the reply. I had the speakers all set to 80hz but I was scared they were going to blow. So I have then set at 100hz. There is no small or large setting on this receiver so I thought 100hz would do. As for the sub situation I was listening in 2ch stereo not pure mode, and I switched back and forth to all ch then back to 2ch and with all channel it was twice as loud. I double checked everything in the set up menu and still couldn't fix it, not a big problem though I guess.

Oh another question when listening to music on my laptop through my system via hdmi cable what should I have the source volume at?

The 705 features Audyssey MultEQ XT. Run it and let the Onkyo determine the best crossover for your speakers.

I got it used for $40 the guy didn't give me a mic for it.

You can buy an ACM-1H mic on ebay for about $25 or get one from Onkyo.

Usually it's best to set the volume at full in source components and use the Onkyo volume for your listening level. And you got a pretty good deal on the 705!

Okay thanks for the advise. Yeah it was a good deal, the guy that sold it thought it was broken (he had the sub plugged into the input not the pre out). I told him that but he already bought another receiver.

Alright thanks and do I need a stand for it? Like a tripod?

It makes sense to have more sub in all ch stereo when everything is louder. In addition if it's not calibrated by Audyssey any room response peaks already present are amplified.

When the speaker is rated at -2dB 65Hz setting XO at 80Hz won't blow it: it is capable of outputting 80Hz. It's not a sharp brickwall cut-off in any case but rather a slope.

Setting the XO to FULL BAND (manual p.77) is the same as setting it large so try setting the surrounds to that or 80Hz rather than 100Hz, or if you're afraid to do that, then set the sub trim or manually turn the sub volume down as an interim measure while waiting for the mic.

Thanks I'll give that a try. Quick question about clipping. If I have the volume too high it will be an audible "clipping" sound right? And if I hear that back off the volume?

I've not actually heard it in my speakers (thankfully) but as I understand it's some sort of cracking sound. Before that there might be less drastic distortions that don't sound nice or right. Hopefully you back off then.

If worried it'd be better to keep the volume reasonable before the mic arrives for calibration.

Yes, either a tripod or a mic boom stand. Refer to the mic related information in the Audyssey 101/FAQ linked in my sig for a recommendation for both.
