Hello

I recently purchased an RM 6200 speaker system with the PSW 250 subwoofer. This was purchased from Crutchfield.

Tonight I was going to start wiring in the speakers and was reading through the manual and it says that you are supposed to use the speaker leve inputs and outputs on the sub to make the connection. It says do not use the subwoofer output on the receiver to connect the subwoofer. I have Denon AVR-2802 receiver also purchased from Crutchfield.

Okay now I look at the Denon manual and of course it shows the sub using the one line going to it via the sub out. Which I orginally thought thats how you do it. I bought a subwoof cable and y adaptor to go into the left and right in of the sub. Thats how Crutchfield is saying to do the hookup and they said it doesn't matter which way you do it. The one line is easier.

Well I sure would like to do this right the first time as it makes a big difference if I have to change everything. It also makes a big difference in the way you do the setup of the reciever.

So who is right and which way is best?

Thanks, Steve

Okay, I've been reading some more and apparently on this sub, since there isn't a seperate lfe in on it, that using the sub out and running it in the left and right line in that you would get a double filtering effect?

Is this correct?

Indeed, you would get a double filtering since you don't have a separate LFE input on your sub. But it really doesn't matter, because then you can still (and should!) crank the crossover dial on the sub all the way up.
As for what inputs to use, speaker-level or line-level, it's really a question of taste. Try both and see what you like best. Just remember your receiver's bass management rules in each case so all your bass and LFE channels are routed properly to the proper outputs on your receiver. Usually, with speaker-level, you want SUBWOOFER OFF so LFE and channels from SMALL speakers go to both left and right speaker-level outputs, and with sub-out line-level, you want SUBWOOFER ON.
Happy experimenting.

Hello

Thanks for the reply, all this stuff is very new too me. I haven't followed the audio video scene for many years. I was still using my old Pioneer SX950 with HPM 100 speakers that I bought back in 1978. Anyway just wanted to follow up here a little.

Okay so by cranking the low pass/crossover dial all the way up will help eliminate this double filtering if I go the the one line level input route? I would like to try this way first as I have already bought a Monster subwoofer cable and y adaptor to go into the left and right inputs.

I have gotten straight now about the receivers bass management and which way to go depending on how the sub is hooked up.

I was just a little confused on which route to take with the sub hook-up because I"ve been getting so many different "stories".

Anyway thanks again for the help and let me know about the crossover dial question.

Thanks

You're welcome.
Since you're using the line-level sub-out from the receiver, which is already a filtered output, you need to bypass your sub's crossover, and this is achieved by setting the sub's crossover dial to its maximum frequency. The idea is actually to set the sub's crossover point at least higher than your receiver's, even higher to give as much margin as possible. Cranking your sub's dial to the max should achieve that effect.
If using any non-filtered source, such as speaker-level outs or pre-outs from the receiver, then the sub's crossover dial becomes handy.

Hope it helps.

Hi:

There is no right or left on a sub, unless you have a sub with two speakers in it. Even then I don't believe you would have a right and a left. The dual input is for the dual voice coil on the speaker.


Set the sub crossover to 80Hz, that should be sufficient.

RESOURCE for you

Sartori I would reccomend you go to
Polk Audio Guide

I purchased almost exactly the same coponents and this manual really assisted me in de-mystifying the hookup process...skip to page 38 on the PDF document for your bass question.
