Avoiding the Crossover Frequency

[jman999]

Here's a major problem I have with my current Home Theater Receiver. When playing a DVD using the optical out, you cannot turn off the crossover frequency. My eventual surround setup will not have a sub, rather I would like the bass to come from the front speakers.

When my receiver is in PCM Stereo mode, there is a direct function that bypasses all DSP settings, however the direct function is not selectable while playing a DVD.

Is there anyway to turn off the crossover? And is there a way that I can I have a crossover frqequency for my center and surround speakers?

Thanks, Jonathan.

I dont have a multi channel reciever but I think the speaker settings for small and large are suposed to fix that.Set them to large.
I could be wrong though.Check your manual to make sure.

I wwould also like set the LFE to come trhough the two front speeakers as well. I'm relatively sure changing the speaker size will not make a difference, but I will try that.

I figured out my first problem which was getting bass to come from all the speakers. I still cannot figure out how to filter the bass from the center and surround speakers without preventing the bass from the front speakers .

hmmm. Yeah,better get someone with more experience with multichannel recievers

Set the center and surrounds to small. That will reroute the information to the subwoofer. Make sure the front speakers are set to large, and the highpass crossover should be disengaged for them. If you set the subwoofer to none, it should play back the bass through the front speakers, provided they are set to large.

My receiver doesn't have settings for small and large speakers, however thre is a subwoofer setting that sort of works for me. I think though that I'm going sell or trade this receiver for a good set of cans. I don't really think that the effort involved with creating this home theatre system with be worth it anyway. I'll still have a good stereo system for when I wanna crank the bass.

What is your receiver's brand & model # - and maybe a link to the specs/users manual? You can probably achieve what you want - we just need more specifics on your Rx.

Hi AzzKiller :attn: !

Onkyo HT-R410: User's Manual (http://63.148.251.135/redirect_service.cfm?type=own_manuals&file=HT-R410.En.pdf)

It's a 5.1 Home Theater Receiver

The manual is not very clear on the crossover - is there only ONE frequency selection for ALL speakers - or are there seperate frequencies for Front, Center, Rear?

I assume you currently have the "Sub" set to "OFF", and the Crossover set to whatever your center/rear speakers can handle? What is your result with this configuration (no bass on Mains, too much bass on Surround, etc)? I would think this wold do the trick (sends SUB LFE info to Mains, Runs the "Mains" in full range {combined with the LFE channel} and uses the crossover for Center/Rear high pass)- but I'm not sure. That is how my Sony DA777ES does it, but it also has seperate crossovers/bypass for Front/Center/Rear/Sub and cost $1500.

Let us know. :cool:

Wire in an HPF between the reciever and the speakers that you dont want to have the lower freqs sent to.

He's about to give up on this project,I doubt he's going to go through the trouble of
wiring in high pass filters.:)

2 100MFd (or so) 100V Non-Polar caps is not all that hard now, is it? It would do the trick, but I'm always a fan of active filtering (before the power amp).

:cool:

I'm giving up on this particular plan, but not on home theatre in general. I'm going to try to find, either on ecost or on ebay a good set of home theatre speakers under $100 to go with my receiver. That way I can just set my receiver to subwoofer mode 1. Subwoofer mode 1 sends all bass lower than certain frequency from all the speakers and the LFE to the subwoofer. Also my speakers will be acoustically matched, which is better for Home Theater anyway.

That way I'll still have my Sansui equipment for music and my HKB6's and stereo amp also for music.

Ecost had a deal before for $40, a set of Kenwood HTB-505 5.1 speakers, hopefully I'll be able to get a deal similar to that within the next couple of weeks.

I wouldnt reccomend using passive capacitors in series with your speakers. A value that large will likely have issues since its relatively close in frequency to the speakers resonance. It could actually increase the bass at certain frequencies.
