Setting Xover Freq for RM6750's on a Pioneer VSX919ahk

DillonK

I have the Sub hooked up via Y-cable as described in the Option 1 manual of the RM6750s, I have set satellites to SMALL and Sub as YES. Now it says to set the Xover frequency at 120hz, but my receiver goes from 80-100-150, no 120. Obviously it is a problem with my receiver or there is another tuning feature I am missing.

My question is, should I just set the Xover to 100hz or 150hz?

Thanks for any advice or help.

Also the manual says to set the Low Pass on the Sub all the way clockwise to 160hz, if I cannot set the crossover on the receiver to 120hz, and only to 100 or 150 as being the closest should I still set the Low Pass to 160hz?

Also forgot to mention I use a PS3 Slim model as my player, hooked up via HDMI of course.

Whether you use the 100 or 150 setting you should leave the sub frequency turned up as high as it goes. The goal here is to not use the low pass filter in the sub and use the low pass filter built into the receiver. You want to only use one.

As far as the setting for the satellites. I would start with 100 and be gentle. Turn them up slowly and see if your receiver is over driving (distorting) the satellites. This will be easiest to detect with the subwoofer turned off (turned on at receiver settings, but actually turned off).

I couldn't find a frequency response for just the satellite speakers, so not sure what their individual capabilities are. If you are not overdriving the satellites at 100, then i'd suggest hooking the subwoofer back up and switching between the settings (100 and 150) to see which you prefer.

The 150 setting is safer, but asking the sub to play that high, it may get a little shouty. The downside to going with 100 (assuming not overdriving the speaker) is that if the satellite can't play down to 100hz, then you'll have a gap in frequency response between 100 and 120.

So basically, determine if the 100 setting is safe (i suspect it is) and then try both settings to see which sounds better in your room.

Ah ha, I found it at the very bottom of the PDF for the manual of the speakers. It breaks down each individual speaker's responses. the satellites overall response is rated from 100hz-24khz. I guess the test now is to see if I should let them go down to 100 or put them at 150...

I'm very surprised at the staging effect I get out of these speakers just playing CDs in stereo. Not bad considering I paid 200$ for the whole set.

The RM6750 is a very capable set of speakers - I think you'll really enjoy them!

Well my next step is to upgrade some of my cables, already have a set of Audioquest HDMI-3 cables on the way.(found them for 30$ each which is a steal). And to replace the junk Dynex 18 gauge speaker wire and Dynex Sub cable...bleh. I'm thinking some stuff from Knukonceptz may work.
