I disagree. Most xovers are slope and band limited. Many do not allow you to crossover lower than 80hz, many offer only a few fixed points. What if I want to change the highpass to smaller mains to 24db instead of 12? Or set the lowpass to the sub to 12db instead of 24db?
Regardless I'd like to have a small list of the processors or recievers that do offer what I would consider excellent flexibility. One processor that I know of that does offer excellent hi/low pass xover settings is the UMC-1. You can ajust the slope and have a dozen or so band points to select from starting around 30-40hz all the way up past 150hz if I recall. But even this bass management system in itself is flawed still due to the sub channel EQ not working for 2 channel music.
The previous statement had a typo, I meant the other way around.
Like? Examples please. And what specific bands? Are we talking about near worthless octave or higher spacing?
Well if you can't adjust a boost or dip in the frequency response at the specific point needed or the with the proper Q, then no its not necessarily better at all.
I have a pair of Onkyo SC 886's and even the 15 band eq it has per channel(and 6 bands for the sub) is kind of limited for my need to maximum fine tuning. I could get the in room response relatively smooth with it(A hell of alot better than Audessy XT ever will)but I ended up with some dips and boosts that were not at the EQ points, so I went with 3 Rane DEQ 60L(2 channels per) 1/3 octave 30 band EQ's instead(5 channels for the mains, 1 for the sub) and the response in room is now near perfect. Something I cannot do with the typical run of the mill processors and recievers on the market. The only home processor I feel is audio worthy is the AudioControl Diva, but unfortunately its major $$$. But there should be more products like that on the market.
