I have a set of 10 year old Sound Dynamic speakers
2 rts-11 (front)
1 rts-c2 (center)
2 rts-7 (sourround)
2 rts-r1 (rear surround)

For the last 10 years they were used in my living room with Yamaha DSP-A1 and they were ok. Recently, I built a dedicated home theater in my basement and moved the speakers there, I also have new receiver Onkyo 806.

I am not impressed with my new setup at all, as much as I enjoy the video part (Panny 4000 with 12' wide scope screen), the audio is dull, it can go loud but I am missing something. I have Ed A5-350 as my sub which works fine, but I feel that my speakers are not up to the rest. My room is not acoustically treated yet, so perhaps that could partially be a problem but overall I am disappointed.
I am looking for opinions about quality/value of Sound Dynamics speakers, especially in comparison to Klipsch, Energy and such.
I am not sure if I should start seriously looking or is this just the room treatment.

Any suggestions will be appreciated.
Thanks,
Wojtek

Sound Dynamics is a sister company of Energy, Mirage and Athena. I think they were gone before Klipsch acquired Audio Products Intl a few years ago. Some of the SD products are actually Energy speakers but yours may not be. You may have an earlier vintage speaker.

Its hard to tell how they compare to other brands because there isn't much info out there. I have a couple of RTS-R1 surrounds and they work fine for me but I've never seen any of their other products.

If you're not happy with your setup maybe it is time to replace them.

I believe that there is something in common between Sound Dynamics and Energy (API group). Should I just try to bring another set of speakers home and audition them together? Perhaps, I should look at buying an amp and using my 806 as a pre-amp?
I am just not sure what should I do next.
Thanks,

I don't know the specs on your speakers but the easiest thing to do is try other speakers. Buy something locally that you can return. Listen to them at home and see how they measure up to your SD speakers.

Did you run the Audyssey MultiEQ function on your receiver? It makes a difference, at least for me it did.

Yes, I did run MultiEQ and it helped a bit. I think I will just get some well known brand and compare.

I haven't heard any of the models you have. But I did test the RTS-3 which was a favorite with the Absolute Sound in the bargain department.

Myabe I just have higher standards than the Absolute Sound.

I have the Sound Dynamics R-818's, not sure how they compare to the RTS line though. I have enjoyed mine for the last 15 years or so, but don't think they can be considered a high end speaker. They get the job done for movies, but may be a little muddy sounding for music. I will be upgrading speakers during the next couple weeks, and the 818's are getting sent down to the workout room. Let us know how you make out!

Wojtek,

By any chance would you consider selling your RTS-C2? I have a pair of Sound Dynamics 300ti's and understand the RTS-C2 would be a good match for them.

Or does anyone have any suggestion for a center speaker to go with the 300ti's?

Thanks.

Best,

Jim
