Receivers usually have a connection specific for subwoofers. Does yours not have one?

whats the best way to wire my subwoofer to my surround sound.

I think your question was answered in another post, but in case ...it helps to match them .. you can look at brand name, impedance, and sensitivity.

From the speaker's data sheet on their website, it looks like they work best with a crossover at 100Hz. The receiver should handle the crossover frequency settings.

I have some old office speakers Altas
FA138T167 that I would like to try with my home receiver, I can just bypass the transformer and they work O.K. but these also have a crossover on them should I run my signal through the crossover if anyone is familiar with these what wire + or - should I connect to the Green and Brown wires going to the crossover?

Hi, I'm new here and was hoping someone could answer a question I have about speakers. I have some old hand me down speakers. They are big and tall but they sound great. I don't have surround sound speakers so I'm looking for some. DO they need to "match" the older speakers I have to sound good? Do I need to buy the same brand?

Thanks thraco for the link you provided. I have learned about Onsia speakers advantages and three key features that set them apart from traditional loudspeakers. They are really great Home Theatre Speakers that produces a good quality of sound pleasing to the ears and never can be considered as noise. Thank you so much, now I am ready to improve my home cinema design.

It looks like the Polk speakers are still cone-based speakers. The Onsia speakers are transducer speakers, so they use distributed vibrations over a flat surface rather than the vibrating cone used by conventional speakers. In essence, the Onsia speakers, at least the in-wall ones, use the entire wall as an amplifier. Onsia's website has some good information about the difference.

Thanks for the input!

I don't have Onsia speakers, but I have some Polk Audio RC55i In-wall speakers. They sound pretty good. I don't think in-wall speakers will ever sound as good as tower speakers, but you can't beat the fact that they are hidden. I'm happy with them.

On a trip to Lowe's a while back, I came across a display of Onsia's flat-panel speakers. The display wasn't terribly informative since they didn't let you choose to listen to one speaker over the others, but I really loved the idea of completely hiding my home theater speaker system, and perhaps my entire home audio system, in the walls. They have three types of speakers: In-wall, which can handle 50W RMS, and in-ceiling and in-frame, which can each handle 25W RMS.

I was wondering if anyone has had experience with installing/listening to these (or perhaps more generically with NXT audio technology in general), and what your impressions are.

Not sure on the wattage, but I think the 8 Ohms was there for the front speakers.

This thing is probably 20 years old, 15" sub in an end table type enclosure, I bought it with a SAE Amp from Crutchfield. My question is: why are there 5watt 8 ohm ceramic square non conductive? resistors across the speaker terminals? I assume this was to limit the output signal as this sub was passive and you could connect your front speakers and the sub all from one stereo channel. Do you think that's what they are for?
P.S.
How many Watts do you think I should look for in a new Amp to power a sub that size?
Thanks
