Designer of (most models of) the Beta Series, excluding the C250.

awesome! thanks for the info

Oops! I meant to say the horizontal dispersion pattern of the C40s matches that of the C360s . Sorry.

Just a big thanks to Phil for sticking around and chiming in on this thread. How many other speaker designers are hanging out chatting with the guys running his speakers years after they have been discontinued. Great guy!

Shock, you spoke for so very many of us who have been edified, educated, and enlightened by Mr. Hart's fascinating post over the years. Thank you.

Well, because of you guys, I am now the proud owner of a c360 to complement my beta 40's! I'm in the process of moving into my girlfriend's place and we have a sever lack of space for the time being. We are going to use an older 32 inch lcd tv of hers for the home theater (bye bye big tv for now ). Is it as stupid of an idea as I think it is to set a lcd tv on top of the c360? Physical dimensions-wise, the stand for the lcd would fit completely on top of the 360 w/o anything hanging over the edges.

Put some magnetic shielding on top of the 360. Otherwise you will see interference from the speaker on bottom of the screen. You can get some magnetic shield foil.

Probably you will not need any shielding (I´m sorry to disagree with you haloguy628).
I have the C360 below the LCD (well, really 5cm below, because I have a stand) and I haven´t any problem.
The Beta series are magnetically shielded and the LCDs are inmune to external magnetic fields as they don´t use them in the display unlike CRT´s.
Anyway, when i had a CRT TV in the same position, I see a very little color distortion in the lower end of the screeen (C360 magnetic field interfering in the tube magnetic field) and I can hear a subtle 50 Hz hum in the C360 (TV´s magnetic field coupling in Speaker coil).
But with the change to LCD all that problems are gone.
Try and see.
If your C360 is not at ear level (mine is below ear level) it is important to tilt the speaker up to aim your ear. In that case you will need a stand for the TV.

Congratulations for your C360. Initially I purchased a C250 (as you to to complement my beta 40's) and changed it for a C360. It sounds much, much better.
As we can´t have the speaker free standing, at least try (if you can) to have the front of the speaker flat with the front of the closet to avoid to have the speaker "inside" the closet to avoid reflections, resonances and modify too much the dispersion pattern.

As others have said:

Patrick Hart, thanks for designing such a beautiful and awesome sounding speakers. 8 Years after I still found myself thinking "I love my speakers, the best buy I have ever made" every time I hear them.
Thanks for teaching us and still giving us support!!

Where the front of one of my cabinets meets the side, there's an audible reverb happening in the cabinet. Holding the side of the speaker firmly with my hand makes it go away. anyone else get this problem? it just started.

So yeah bought the xpa-3, hooked it up. Opening scene of guardians of the Galaxy, and POP. It was that dreaded sound. If you've heard it you just know. A blown speaker. I quickly paused the movie, pulled off my panels and check out the speaker. A quick touch of the woofers and no problems there. I turn it back on and it's crystal clear. I'm behind the screen now and i hear strange air movement, and it happens again. It's coming from the side. Sure enough, the xpa made my speakers literally rip the cabinet apart. I've owned beta 50's (cherry finish) since 2005, and this particular pair(black) since 2010 and never felt stressed about blowing them. Tomorrow I'll pull the speaker apart and see if I can't reinforce the cabinet. Worst case scenario i caulk it from the inside and hope I don't need to go in there again.

Will take pictures for those interested

so looking inside there isn't much holding these together. looks like they glued them, then added some 1/2 x 1/2" blocks randomly with some more glue, the two on the affected side just fell off and were in the cabinet. the two pictures show how much flexing the side does with just a push of the finger.

I added silicon glue all along the inside edges, will let that harden, then will add silicon caulk, and a clear silicon caulk on the outside too. then, i'll probably add a screw to hit that bracing in the cabinet to pull it all in tight.
