Help me WmAx; you're my only hope!

Buck,

> why wouldn't I require the response from each speaker on its own to determine what to do with the PEQ for each channel? <

Because the sound at any given location in the room is the combination of both speakers. Each speaker also causes reflections off all the room boundaries that combine to give a single reponse at the listening position. And when both speakers play there are even more reflections all combining to give a single response. So to play only one speaker or the other ignores the combining that happens when both play.

That's me! I truly understand that I don't know much!

I did not mention this, as this thread was about measurement and equalization, not room treatment(s), specifically.

I agree my friend. I was only pulling your leg.

Thanks. Now I understand. For most of today, I have been reading the room treatments articles from this site and must admit, I'm starting to swing towards treatments rather than PEQ, though who's to say that I won't require both to obtain the best sound I can?

I'll have to wait for the splitter to arrive in a few days before I start taking my own measurements, but I'll return to this thread once I have.

Once again, many thanks to all for your help. Just as Sploo mentioned in his original "Yes, it's another Bass Traps thread" thread, I am finding this subject fascinating. The added bonus of course, is that the knowledge I attain should hopefully unlock even more glorious sound from my system. Here's hoping.

Kind regards

Robbie

Both are required[though the type and amount of each that is optimal is dependant on many variables], if optimal response is desired. For example, you must use a PEQ in combination with bass traps, if you want the best bass response. Also, tonality adjustments[due to preference, or just distance vs. HF response as I indicated earlier] require a precision equalization unit. Also, a precision PEQ can allow you to customize the bass rolloff characteristics of your speakers, allowing you to obtain any type of 'bass signature' or 'percieved tightness of sound' that you desire.

Absolutely. I've hit the limit of what I can (aesthetically) get away with in terms of panelling in my room, so the next step will have to be equalisation.

I've not yet had time to look at any PEQ's, though I have contacted my receiver manufacturer (Arcam) in an attempt to see if they could add some form of PEQ into a future DSP upgrade.

Probably wishful thinking, but it's surely the best place to do it (as opposed to an external box between your DVD/CD player/PC and receiver).

Change of plan folks. This thread has warped from one about PEQs to one about bass-traps, so I've decided to start a new thread here.
