reciever question

I was wondering if I was going to hook up a second subwoofer to my recievers one output through a y splitter would this cut the power to each sub in half. If so would that mean that I would get the same output out of two subs as I already have right now?

I have the ONKYO HT-S5100.

Re: reciever question

I looked at the specs and I can't find if the subwoofer is powered (I didn't see the owner's manual). If it is powered, then you can safely add a second sub. If not, then you should not.

Why do you want a second sub? Do you have something in mind? Replacing the sub that came with this system would be a better option if you replace it with something decent.

EDIT: Found this on Amazon - SKW-560 Bass Reflex Powered Subwoofer. Looks like you have a powered sub, so yes, you can add a second one with a y cable.

Re: reciever question

Im not really sure but I just thought that if I had a second of the same it would be alot cheaper than buying about a $300 dollar sub. Would you think that the output would be about the same. If I am correct the two subs would be about 600 watts max. And both would be 10". Or do you think I suld go with one sub with a little less power. Im trying to get a TON of bass without braking the bank. I think about $350 would be my max.

Thanks alot

Re: reciever question

Could you do $429? SVSound - Box Subwoofers. Replace the Onkyo sub with this one (do not use both).

Adding a second sub of low quality will get you about 3db more low quality sound. It could even out the bass in your entire room, but that's not what I'm thinking is going on here.

Re: reciever question

I have a pretty small room. About 12" by 11". Could this be part of the problem that it is a square room and the acoustics are not very good. There are some loud spots but for the most part there are alot of dead spots. would that one higher quality sub help with that or will it be better to get the two which like you said would be a good way to even out the bass.

Re: reciever question

I would start by moving the sub around the room to see where you get the best bass. It's all about location. Sometimes moving the sub only a few inches makes a big difference. It takes time and patience.

Have you calibrated your speakers?

Re: reciever question

I just the the auto calibration that came with the system and then looked back at what it did. It seems to have the speaker distance almost perfect. The speakers sound great but its just a lack of bass.

Im going to rearrange the room a little and see if that helps.

Thanks

Re: reciever question

What are the crossovers set at? Sometimes they get set to full range with the auto setups. Then you won't get much from the sub.

Re: reciever question

And if you did decide to go with another subwoofer, there is also the DIY alternative if you have the tools and time to make your own.

I made by sub a few years back when we had a thriving DIY forum and I have maybe $200 into my sub (shopping around helped me a ton) I was able to score an OEM 500 watt Bob Carver TDC plate amp for $50.00.

If that's not an option, SVS is where it's at.. And like David said above, a few inches can make a TON of difference in LF output. Also if the sub can be disassembled, Polyfill stuffing may help if the sub you have now, is not stuffed. This was also a big DIY mod for the Sony subs a few years ago.

David the crossover is set at 100hz. On the reciever it can go between 40hz-200hz.
