PSW450 question

joelc73

After reading much of the advice posted on the topic, I'm considering running my sub using RCA cables out of the pre-amp outs on my Onkyo 676. Does anyone know where to get the Y-cable needed to hook up the sub while still sending a signal to the pre-amp? I tried Radioshack but couldn't find any.

I'm currently running a Monster cable out of the Onkyo subwoofer out into the unfiltered LFE input on the PSW450. Will using the pre-outs add a noticable difference, or am is just being anal?

I'm using RT800i's up front, a 400 center and 500fx surrounds.

Thanks,

Ya, I have the Onkyo787 and I run my two subs and my rt1000's using y's ----all in series from the sub out on the reciever. Actually about a year ago all Monster sub cables use to come with Y's in the kit. Then they got cheap and stopped doing that. You can buy them seperatly from monster for about $20. I use a Monster Y with all four of my sub's and it sounds great. Hope this helps. Later :cool:

Also have 450 subs. The Y connectors came with the
monster cable.
Unless you are running your cables to your sub first, then to your speakers, nothing is gained by using the Y.
Connecting to your LFE (unfiltered) input on the sub bypasses the second filtering, and gives the most sound.

I'm not sure if I understand what you're trying to do. Are you trying to run the pre-outs to an amp AND to the sub? If you are not, then you should just run the L&R front preamp outs on the receiver to the L&R line in on the sub. No Y-adapter needed in that situation. You will want to make sure that in your speaker set-up, you have your fronts set to large and subwoofer set to "off", or "none".

Of course if you are running an external amp, or your receiver has pre-out, main-in jumpers, then you WILL need the Y-adapter.

Concerning the sound: As far as I can see, there really wouldn't be any benefit to using the "pre-outs" instead of the "sub-out", for your application. By doing so you would be able to alter the low pass frequency for the sub, but the high-pass to your other speakers (if any are set to small) would still be up to the reciever.

Thanks for the responses.

To clarify what I'm trying to do; I want to take the signal out of the pre-amp section of my Onkyo and split the left and right so that I can run left and right signals back to the power amp (as it is currently) and also run left and rights pre-outs to my PSW450.

I've been told this is the optimal way to hook up the sub, as it gives you control over the sub's crossover (which you lose when using the LFE input).

Again, I've heard a lot of ideas on the subject, so I'm not really sure what's best.

Thanks again.

this is how i have one of my subs connected and it works great. i too have an onkyo. the only thing i will suggest is that when using this set up do not use a sub cable use a L&R patch cord.
when i did this set up i used a 2 male to 1 female "Y" and a mono sub cable to the sub, i was getting L&R signal in both my mains. it was like having a giant mono system yet still having stereo
