Crossover settings/RTi10

dcacc

I'm sure there have been dozens of discussions about crossover settings, so I hope you'll put up with one more.

I just got my Onkyo 805 and am using them to power my RTi10, which I have paired with a HSU STF-2 subwoofer. When I run the Audyssey setup, it sets the 10s to Full Range (or large).

Everything I read says it's better to switch the crossover to 80, but when I do that, the sound seems thin, no matter how I set my sub. It sounds better to me with the 10s set at large.

I know: If it sounds better, keep it that way. But I'm just wondering if I'm missing something.

Also: Could someone explain what the low-pass filter does (I've never quite picked up on this)? Audyssey set it to 80, but my surrounds were set at 120 and my center at 90. I have no idea how all those setting interact. Any advice?

A low pass filter is a crossover that cuts off treble or higher frequencies. A low-pass output is designed to feed a sub.

A high pass filter set to 80 Hz would protect your center speakers. A low pass filter set to 80 Hz would feed the sub.

Essentially, setting the crossover to 80Hz on the front would mean that all signals below that frequency are passed to the sub and not to your fronts - this results in the "thin" sound that you describe by essentially throwing away any directional low bass that you would get from the RTi 10s, since they can produce significant sound down to ~35Hz.

Looking at the specs of the speakers, if you really wanted to set a crossover, you should set it to 35Hz, so that the -3dB (aka half power) point of the speakers matches the receiver. For speakers like these though, you should just leave it at full range let the crossovers in the speakers handle the transition (this is the same as the full range setting you are using now).

^ werd....as long as you are near or above the freq of the RTi10, you should be okay...but I would not let the main RTi10 to have full range because I don't want to send full range signal to main and burden the Onky 805...but it's capable tho...

I set the freq to 40Hz on main speakers because that's what they can handle...there's nothing wrong with sending full signal tho....but main speakers would not be able to generate sound....also same applies to center and surround....if your center can handle freq to like 40Hz, then set the freq of the center 40Hz and above...so anything below 40Hz will not be sent to center speaker...

set the 10's to large.

Where can I find an upgrade crossover for my RTi10’s? I was going through and reconditioning my speakers upgrading braces and no-rezing them and putting them back together with no luck finding the one bag containing poly fill, bases with spikes and terminal connectors/crossover. Purchased all but connectors/crossover cups. I was planning on upgrading those anyway and was thinking of sending them to Danny (GR RESEARCH), but happened to come across a site that was about doing this exactly and had upgraded crossover networks built. I can’t find site now. Anyone know what that website is the specifically does this floorstander and a few other units?
