@jeffreybehr did you pull your speaker apart for the crossover pic or is that a stock photo?

This afternoon I do. .. .. A very good friend is my speaker-crossover-schematic genius. I'll add a scan of it to this note.

After seeing the schematic:
Tweeter; 3rd-order high-pass. Corrected the schematic after my audio guru didn't believe it. I'll replace the 10- and 18uF caps in series with the tweeter with metalized-'propylene SoniCaps with 0.47- and 0.96uF SoniCap Platinum bypasses.
Midrange; simple 2nd-order bandpass. The electrolytic caps MUST go. Will use a SoniCap-1 for the 25 and a Mundorf MCap EVO Oil for the 45.

BTW the speaker has a tweeter-level control (from -1dB thru +1dB in half-dB steps) and a wall-proximity switch built into the input-terminals cup. Probably won't do anything with those.

The "tweak" on the tweeter filter, if you are referring to the series cap to ground, is to help compensate for the inductance of the driver.

Don, I've corrected the schematic; no tuning circuits in the x-over.

I mix films occasionally, and in all cases, films are mixed with identical speakers LCR. There is a perception that only dialogue comes out of the center speaker, but in actuality music, explosions, gunshots, etc. all come out of the center speaker too.

I am running the Voice2 with my Salon2s, and it's a pretty seamless experience.

Here are spins of the speakers you are asking about:

M105:



C205:



C208:



Voice2:



To illustrate my point about movie soundtracks, here are some screengrabs of actual movie mixes. They are arranged in the following order: Left, Right, Center, LFE, LSur, RSur. You can see that in action scenes the center is still the most active speaker:

INDIANA JONES - CRYSTAL SKULL - Cliff Chase:



STAR TREK (2009) - Enterprise goes to warp:



Hope that helps!
Thanks John. I am wondering if center channel also has content between 60 and 100 hz. If it does, even with a good sub crossed over at 80, there will be substantial energy that will come out of the center speaker at 60 of even 40 Hz.

In that case the center speaker must be able to handle these frequencies without distortion, just like left and right speakers.

Thanks.

Center channel may have content down to 40 Hz and below, especially on music videos where the bass guitar may be mixed in the center channel. Low E string on a bass is about 41 Hz.

The idea is to cross over the center channel speaker higher (around 80 Hz) so it doesn't have to handle all that low frequency material. Less amp power required. Seems counter intuitive to buy speakers that have low frequency extension capability and not use it, but a lot of folks do it. Many Salon2 owners let subs handle stuff below 80 Hz. Remember, if you set the crossover at 80 Hz, that doesn't mean there is a brick wall filter and everything below 80Hz is just cut off. It's the turnover frequency and only down 3 dB at that frequency. The slope of the filter determines how fast it rolls off.

You can play around with crossover frequencies. In a recording control room I setup, I set the crossover closer to 65 Hz and felt the mains integrated with the subs better than setting the crossover at 80 Hz.

I crossover at 80hz for movies but 60hz for music. Movies are brutal on low end so I tend to leave that job to the 3 subs. My music listening tastes are not generally too bass intensive and I find I prefer the more seemless blend of the lower x-o frequency. If I had stand-mount fronts or small towers, I might tend to go 80hz all around.
