The usefulness of the RTA continues to amaze me.
1...I have explored the effects of different SW crossover frequencies.
2...I discovered that one of my six subwoofer drivers got wired up backwards (recent wire rerouting).
3...I discovered that the rear speakers had a large LF (below 200 Hz) boom. (Ported...what should I expect). Like many rear speakers, mine are not optimally located: they are high up in a bookshelf alcove. The boom itself was not that noticable, because you are never sure what ought to be coming out of the rear speakers, but it seriously disrupted SPL matching between front and rear speakers. I fixed the boom using my old LF Richter Scale equalizer, readjusted the SPL balance, and the improvement was large.
4...The parametric equalizer that I am presently using for the center front speaker has five bands plus high and low shelving filters, but, dispite about an hour of work, it does not enable the flat response that the DEQ2494 achieves in about 90 seconds of completely automatic room equalization.
I tell you guys, buy one, even if it is just to measure how your speaker placement and room treatment is doing. I expect that after you hear your system with the EQ in you won't want to bypass it.
If this isn't enough, the price is down to $300, and even $250 for B stock.
