Yamaha 663 & Bose Acoustimass 10

[tburke007]

Hello All,

I just purchased a Yamaha 663 and a Bose Acoustimass 10 system. Does anyone have any information on any special settings / tweaks to optimize the two systems to work the best together? While I realize there are better speakers out there and the uy [O]ther ound [E]quipment acronym . I am happy with the Bose and they seem to perform well for me. Any feedback would be appreciated. Thanks

Just run the YPAO and then recheck the crossover and "size".

Ditto........

Yep, just be sure the cubes are set to small, don't want any bass going to those (waste of the receiver's power and hard on the speakers).

The auto calibration such as the YPAO can do some wacky things sometimes. If you do use this for calibrating your system, manually go through the settings and double check everything to see that your speakers are set to small, check the crossover setting you want as well as the subwoofer gain level. The last time I ran an automatic calibration I checked right away and saw that it set the SW gain to -7.5, the crossover at 40 and set all my speakers to large:eek...if I left these settings like this the subwoofer would never come out of standby....then tinker the settings to your liking.

It's really unfortunate that Bose doesn't post the frequency range for the Acoustimass. They do, however, have the Acoustimass 10 manual online. It states on page 11 that the crossover should be set to 200hz for the bass module.

Now for the fun stuff. The manual states that the speakers should be set as "Large" for the fronts and "Small" for the center because the speakers are "full range". That really isn't possible...a 2.5" inch speaker isn't going to reproduce anything very low. (It's cute that they trademarked them as being "Twiddler speakers")

In short, all speakers to small and crossover at 200hz because the cubes won't reach that low (way too high for a subwoofer to run, let alone something that wishes it was a subwoofer, IMHO).

Alright, maybe I'm missing something, because I'm going to disagree with everyone here.

The Bose Acoustimass 10 system doesn't use a separate subwoofer connection - it only uses the speaker-level connections for the front/center/rear speakers (all of which are routed through the Acoustimass module), and the frequencies are filtered by the Acoustimass module. So, I'd follow the recommendations that are in the Bose owners manual (thanks to Pat for providing the link).

Why the center channel is supposed to be set to small, I don't know. However, I'd do what it recommends, at least to start with.

Add a sub

Since the Bose "Bass Module" works with the cubes and covers the mid range down to 60-70 hz, consider adding a subwoofer to your new system. This will allow you to set the bose system to small w/ 80 Hz crossover instead of full range. I decent sub will play down to the 20-30 Hz range.

Just ouf of curiousity, how much did you pay for the Bose system? When & where did you buy them?

 

[GlocksRock]

I would still reccomend selling the bose system and getting something else. You can get a way better system for the money and have a lot better sound quality.

Let's hope it wasn't much! LOL.

This is correct. The cubes plug into the bass module which is where the crossover exists. It seems the crossover is set differently for the center channel. Do exactly what the manual tells you to do.

If you just bought the Bose system, return it. The Yamaha 663 is a good pick for a receiver though.

You cant disagree with what I said, I didnt really say anything....

I would still sell the Bose and go with Orb Audio instead. Far superior sound for a cheaper price and you get the same form factor as the Bose.

I'm going to disagree that you didn't really say anything.

And then I'm going to disagree that Adam disagreed with what you really didn't say.

I'm just disagreeable.

Is this a bose fanclub? I completely Disagree with THAT......

 

[tburke007]

Thanks

Well, it seems to be a unanimous about Bose. I am going to return it and looking at getting the Klipsch - Synergy Series Quintet III 5-Piece Home Theater Speaker System and the Klipsch - 10" 420W Powered Subwoofer.

Why the center channel is supposed to be set to small, I don't know.

I have an idea; if all the satellite speakers are routed through the Acoustimass module to high pass them, and the only connections between the Acoustimass and receiver are speaker level, then setting the center channel to small will effectively remove any bass from that channel, because the low pass from that channel would be sent to the subwoofer pre-out which is connected to nothing. Therefore preventing voices from coming from both the center channel and the bass module.

 

[ParadigmDawg]

Ok, I wasn't going to Bose bash just because your post was worded correctly and you said you liked them. Now that you have seen the light, let's play this through a little better. What is your budget, room size and constraints?

BTW, I dont like the Klipsch system either. Do you have to buy this stuff at Best Buy?

And the plot thickens...
Let the myriad of suggestions come rolling in!
