What does this mean...."The cut-off frequency of this jack is 90hz"

Seaward

Hi all,

I have a Yamaha 5560 Reciever and was reading the manual about the subwoofer output jack and it said that "The cut-off frequency of this jack is 90hz" What does that mean exactly? Currently I have my sub hooked up to this output jack (PSW202 now --- am considering upgrading to the 404). Is this considered (the 90hz cut-off thing) to be bad?


Thanks,

I think that means that frequencies lower than 90 Hz are sent to the sub. It is not a bad thing, I believe that most receivers are set around 80 - 100Hz. If you use the speaker level inputs on the sub then you can set the crossover where ever you want.

so I'll still get the full range of the LFE signal (below 90hz) sent from that jack?

What does it mean when you say "If you use the speaker level inputs on the sub then you can set the crossover where ever you want."

As you can probably tell by these questions, this is all new to me, but I must say that browsing this forum is and has been extremly helpful.

Speaker level inputs on the sub are used instead of the LFE-out from the receiver. Basically you wire fom your receivers speaker terminals directly to the sub speaker inputs, Then from the sub speaker outputs to the speakers themselves. This will allow you to use the phase and crossover controls on the sub and make adjustements to the crossover point beyond what your speaker is going to allow (90HZ).

Welcome to club polk Seaward,

The polk manual is pretty good at explaining basic hook up etc. I suggest you read it over so you will know which way is best for your system.
