    Thank for the comment on the Sonance. I need to find a local dealer that carries them.

    Hope this helps!
    David, thank you for the response. I have a few questions for you:
    1) What should I look for when trying to match surrounds/height speakers to the front LCR? Should the surrounds and heights have a similar sensitivity? Or that doesn't really matter?
    2) As far as efficiency/sensitivity. Have been reading other forums where some say higher sensitivity/efficiency speakers at 97db+ would be a lot better for Home Theater use without external power amps....What are the trade-offs when designing a speaker with a higher sensitivity than say the Sierra Towers?
    3) I'm planning on running these with only the amps from a receiver, whether a denon 6500 or MRX-1120 or Integra R1.... Would these be enough to power the Sierra Towers/Horizon plus the 8 surrounds/heights?

    So I looked up Sonance, found they are also based in San Clemente.

    They your poker buddies, Dave?
    Sierra-2s in study, Sierra-1 NrTs in office, HTM-200s in kitchen. Brother owns CMT-340s and dad has a pair of CBM-170s.

    Funny thing, they are just up the block from us and I only find about 6-7 years ago.

    Since placement is so different, I generally recommend keeping the sensitivity withing 6dB of the fronts. You generally want all surrounds/heights to be fairly neutral speakers with wide dispersion.

    Our towers have excellent efficiency. Unless you are looking for insanely loud volume levels and in a huge room, there is absolutely no reason for 97dB efficient speakers. The trade-off to achieve this efficiency is huge, very short voice coils, very low excursion, basically little to no bass below 100Hz, use of very different tweeter technology that has shortcomings with regards to linearity and extension... In my professional opinion, you sacrifice sound quality for the ability to play at volume levels that are damaging to your ears. Now, that is not to say they won't sound great for home theater, but when listening to music - differences become obvious.

    Absolutely, not even a concern. It would be one thing if you were running speakers in a large room rated at 83dB or lower sensitivity - but our towers are rated at 90dB, this is high. It means at only 1 watt at a distance of 1 meter, one speaker will reach 90dB, which in itself is considered loud.

    Thank you Dave. I truly appreciate your responses here.

    I got a little lucky with the surrounds, but I was wondering how would these match. My brother moved into a house where the previous owner left his 4 surrounds mounted on the wall. He is giving me those as they look brand new and work fine (he tested them). They are Revels S16 models.

    I'm planning on just using these as the 4 surrounds. It looks like the specs show the same efficiency as the Sierra Towers at 90dB for this But I'm not sure how the 1" aluminum Tweeter would match/work with the Raals on the Towers and Horizon?

    My apologies for missing this. The Revel S16 will be great as surrounds with our ribbon towers as fronts. No concerns at all...

    I just got my Sonance VP62R SST/SUR speakers installed yesterday. These ones have the dual tweeters, not sure if they are better than the standard ones, but this is what my buddy recommended. I also put them in Dynamat Dynaboxes.

    They sound amazing with my Sí2s and Horizon. Blend very nicely. I have been only running a front stage for many years and getting back to a 5.1 again is awesome. Crazy how much more ambience is added to movies and concert dvds.

    How well do the Dynaboxes work with low frequencies? Did you also look at the retrofit enclosure that Sonance sells? They claim 20 dB sound reduction although don't specify frequency range, then again Dyanamat doesn't make any claims so it's hard to differentiate.

    I didn’t even consider the Sonance enclosures. Didn’t realize they had them until after I bought my stuff. They are quite a bit cheaper(looks like $45 msrp for a pair) and appear to be a little easier to install, although the Dynaboxes were pretty easy to work with too.

    I guess I’m not sure how the Dynaboxes are with low frequency sound reduction. To be honest I never even went upstairs to check and see if any sound came through. I run everything crossed at 80hz so nothing real low going through them. I will have to check this tonight but just going by feel, not much should get through them if anything especially just using as a surround speaker.

    The boxes are a fairly thick rubber material and the inside is fully wrapped with foam. The foam that wraps the inside perimeter of the box is pretty dense/heavy and is 2 layers separated by some sort of rubber strip/divider. The back flat portion is the typical eggshell type foam.
