Ssub woofer help

[Big Daddy]

• Take the RCA cable out of the unfiltered input and insert it into the Left (L) channel of filtered. This is according to the Polk manual.
• If you use a Y adapter (1 female, 2 male) and connect the subwoofer cable to both left and right channel of the subwoofer, you may get an additional 3+db of output without turning the volume up.
• Turn the volume up on the subwoofer to the 3/4 point.
• Turn the crossover on the subwoofer all the way up to 160. You are controlling the crossover through the receiver.
• In the receiver's menu, set all your speakers to small.
• In the receiver's menu, set the crossover to 80 to 90Hz.

Hopefully, everything will work after this. Once your system starts working, you can tweak the settings a little to get better results.

Even when you have floor speakers, it helps to reduce the burden on them. Not too many floor speakers are capable of playing low frequency sound effectively. Remember it is not an attack on you or your speakers. It is all about making your system sound better. I am glad your system finally worked. Enjoy your movies and have a great time.

TRY IT BOTH WAYS AND SEE WHICH WAY SOUNDS BETTER.

I think what he meant to ask was are the RTI speakers some of the few that DO handle low frequency bass well. OP, correct me if I'm wrong.

Even with RTi speakers, it may help to set them to small with a crossover frequency of 50 to 60Hz.

I use the Definitive Techonology Super Towers with built-in 15" powered subwoofers. They can go as low as it is possible. When I listen to stereo music, I set them to small and set the crossover frequency to 40Hz and let the three subwoofers (I have three of them) in the room take care of low bass. To my ears, it sounds much better than when I set the front speakers to large.

Follow the guideline in the manual. The manufacturer knows best. They built the sub.

I have the Polk PSW125 sub, and I love it. I would imagine that most of the reviewers who complain about this sub being too boomy may not realize that the sub's low-level LFE input is, in fact, unfiltered, and feeding the LFE signal to it will bypass the sub's resident crossover adjustment.

If your amplifier has a low-pass crossover adjustment, then you can use the unfiltered, single LFE input, using the amp's crossover settings. If your receiver doesn't have a crossover adjustment for LFE, you can most certainly use the L/R low-level RCA inputs on the subwoofer with a Y-adapter at the end of the standard, single LFE signal cable. Then, you can use the sub's resident crossover control. It works mighty well this way.

Incidentally, the Polk PSW125 instruction manual does not show the latter as an option. The instructions are fairly basic, offering more reading as language options than detailed information. Plus, Polk (like most companies) is being careful not to put in writing anything which can be misconstrued, leading to greater user error.
