Do I have my sub hoked up WRONG

BOTTLEDZ28

I have a PSW250 sub hooked up to an Onkyo 701 reciever and after reading some info in another thread, I think I may have it hooked up wrong. First, I have a SUB OUT on my reveiver and a SUB OUT in the PRE OUT section on my reciever, I have a RCA splitter connecting the sub. the single end is plugged into the SUB OUT and the dual end is plugged into the L and R line level input on the sub. I do not have a LFE input section on the sub. the directions state that I should be running my mains off the sub? Can someone explain this? What harm am I doing by running my sub in its current configuration?

heres whatcha do....take your sub cable and put it in the SUB OUT on your receiver. connect the y-splitter at the end of the cable. then plug the y splitter into the subs L&R INs. turn the crossover on your sub (the knob with the numbers like 40, 60, 80, 100...not the colume knob) to as high as it will go. meaning turn if 100 is the highest turn it to 100. start with the volume on your sub at about 1/4th volume.

to hook up your mains take speaker wire and plug it into the Main L&R speaker output on the back of your receiver. its as simple as that.

look through the manual of your receiver to see how you can change the crossover frequency. if your receiver doesn't have a variable crossover then dont worry about it but if you can change it, set the crossover to 80 hz. I'm not sure what kind of speakers you are using but 80 hz is the norm. if you have bigger speakers like rti12's or rti150s you would probably want to set it lower, maybe 60 or even 40 hz.

i hope this helps

thanks for the quick reply. I am running r50's for mains. I already have the x over in reviever set at 80hz but I am going to go and check it all out again tonight. I am thinking of adding a second sub if i can get a killer deal on it, would this be wise or just overkill to have 2. and if I can add a second sub then can I just put the splitter I already have on the end of the RCA wire and then send one wire to the L on one sub and the other to the other L on the secong sub? I read somehwere here that connecting both L and R's on one sub wil increase the the sub 3db's? What does that mean............................ Or should i just get a BIGGER single sub:D

I don't think anyone would acuse you of overkill for running 2 Polk PSW250's.

If you really want more bass, I would recommend waiting until you can purchase a beefier unit. (SVS, HSU, Sunfire all come to mind) Even the smallest from any of these lines will blow away what you are using (even if you had 2 of them).

What brand and model you get are up to you, your budget and the space you can give up.

I would plan on giving your current 250 to someone (I gave my old 350 to my brother in law) or selling it on e-bay. Once you hear the output of any of the subs listed above, you will not want yours hooked up anymore. (smile thats a good thing... )

I hear ya. why is it that one upgrade creates a chain reaction for other upgrades:D I love it. I'll be keeping this sub for a little while longer as the other tenents are already getting mad. I can just imagine if I picked up a better one. But anyways, thanks for the tip.

Chain reaction..!?!

If your not careful,
One day you wake up on the living room floor...surrounded by speakers...and your wife is beating you with her shoe..!!!


Enjoy !

We frequently tell folks to buy something better, its not really a bad idea and you will likely want to upgrade at some point. But if you can get a killer deal on another one or are on a budget then the answer to your question is yes you can split the signal with a Y connector and plug into each sub. I would stack the subs on top of each other.

I am not sure if the 250 has the LFE input like my 450's. You may be double filtering the signal with the ONK if the sub does not have an LFE input. You could run your mains speaker wire from the receiver straight to the sub and then from the sub back to each respective speaker.

You may want to post in the sub forum as there are many sub-guru's who may have a better solution.

wouldnt stakcing the subs cause a vibration between the two?

reeltrouble1

Not a problem stacking as far as the two subs are concerned. If you get your equipment rack close the gear may vibrate and that would not be a good thing.

I originally had my subs front and back, I resisted stacking them initially, but after getting that advice here I did and was very pleased with the result.
