Can Low-End Onkyo feed center-channel sub

post #1 of 7
Thread Starter 
Hi everyone,
Recently (today), I became the proud owner of a Definitive Technology center channel 2300 speaker. The eBay price was too good to pass up... This speaker has a 150W sub built-in. I am currently using a low-end Onkyo SR304 receiver 5.1, and while I would like to upgrade some time, that probably won't be happening any time soon. Can a receiver such as mine take advantage of the sub in the center channel? Will that be automatic, and do receivers send low frequency information to the center channel speakers in general?
Thanks!!!

Since it is a powered sub, you should be able to connect it to the sub preamp output on the receiver.

It seems that my onkyo only has one sub output on the rear panel. Does this mean that I wouldn't be able to connect a dedicated subwoofer to this receiver?

Alternatively, if I should get floorstanding side speakers, like def tech's BP700X line, that have built-in subs as well, would those work with my onkyo, in tandem with the CLR2003 that I already have?

Thanks for everyone's help...

That's all you need to connect a powered sub. One cable.

However, the Definitive Tech is, imho, a non-standard design. You should use it set as a full-range speaker and it will send all the center, low end signals to its woofer. It will NOT get LFE because it is not really a sub-woofer.

Yes it can.Just set the center to small and put a Y adapter on the sub out of the receiver.One cable goes to the sub and the other goes to the sub/LFE input on the 2300.Or you can set the center to large and just run the one speaker wire to it.

Right. I had forgotten about that option. Of course, that assumes the so-called sub on the Polk is satisfactory.

It's a center channel speaker with a built-in powered "sub". It is meant to only reproduce center channel info.

It's unclear how you wish to use it, CodeWarrior, but using the center channel speaker's powered "sub" as your entire system's subwoofer is not a very good idea. Is this your plan? Unless that is what you are trying to do, using a Y-adapter to send the receiver's entire subwoofer output to the center channel speaker's "sub" is a bad idea.

Does the speaker even have a pre-amp level input for its sub section? The speaker has provisions to allow the powered "sub" to work with a standard speaker-level connection. Just wire the speaker conventionally. This would be the best way to connect it for center channel use, especially if the receiver has no center channel pre-out (and even if it did, it's still probably best to use a simple speaker-level connection for this speaker). No need to use a pre-amp level connection.

The "sub" in the speaker is powered, CodeWarrior, so your receiver won't be driving the "sub"; the receiver's quality is irrelevant. If you really want to take advantage of the speaker's "sub" you will want to set its size to LARGE in the receiver however, even with the powered "sub", whether this speaker really is a LARGE speaker is arguable.
