In Reply to: RE: Center Speaker Recommendations for Main Horn Speakers posted by cin5 on August 16, 2024 at 15:38:46
Sorry; I had posted the wrong link. The mains Troy's building for me use this midrange horn.

The B&C DCM50 midrange driver which Troy measures and does listening tests on in this video-please watch entirely from time 15:18 to the end of the video. https://www.youtube.com/watch?v=8haDt66kueM&t=982s
And the tweeter (which Troy not I) insists on using is the Fostex T900A, for which Troy developed these two improvements:

https://www.youtube.com/watch?v=e6QiCzbUhkg
Finally, the above would be crossed with these Altec 416-8B woofers. https://www.youtube.com/watch?v=-bo-g5-EFuQ&t=25s
From evaluating those videos, I hope you might share your predictions of what these completed speakers might sound like.
Given the drivers and the overall design, would these speakers serve for the front speakers in for a 3.1 movie sound system as they would for a two channel stereo system?
Unfortunately, Troy informed me that he's no longer doing custom speaker designs and has now switched to only offering turnkey speaker systems. Thus, he declined to build me a center speaker. So, perhaps this model?

Or one of these? https://www.safeandsoundhq.com/pages/search-results-page?q=center channel speaker&page=1&rb_vendor=Dynaudio|GoldenEar|JBL&rb_price=1105,4250
Follow Ups:
You would have two Large hi efficient 3 way horn loaded speakers that will give dynamics with the " jump factor" on 10 watts.Most commercial available center channels will give an impression of dynamics with little jump on 150 watts.
I think this might be a case where a moderate footprint vintage or ProAudio dynamic driver/ horn mid/tweet combo will fit far better to your needs than classic lay on side center channel
Another option might to use a B&C Coax driver shown in link. No issues with normal center channel comb effects no matter where people sit in relation to screen

Thanks for the ideas but none are options. First, while I have good soldering skills have next to no woodworking skills-and my day job and other commitments leave zero time to build anything. My the screen of my 65" OLED TV would be blocked by any kind of large vertical center speaker. That's especially because I want the height of the TV ~ 10 ft away such that my gaze will fall very close to the screen's center.Consequently, the TV has to be mounted on a stand like this and placed on the floor, or if necessary, a ~ 5" riser. https://www.newegg.com/p/169-01UY-00141 I would estimate only ~ 9.5" clearance from the floor to the bottom bezel of the TV-only enough space to fit some center speakers by KEF, Dynaudio, B&W, et al.
Obviously, I'd have to find the model with really excellent off-axis response and dispersion, though of course the center speaker would also have to be placed on some kind of wedge to elevate the speaker to have it as close as possible on axis with my ears.

A wedge stage monitor might be just the less set of compromises
Don't have to make them
Many offerings but not all are equal. Quality in Pro Audio comes at a more reasonable cost than hifi.
Lift the TV. The top of my screen is eight inches from the ceiling, allowing placement of any speaker I wish below it. The viewing angle is better too.
??? Don't understand. What's your screen size? If your screen is only ~ 8" from the ceiling it must dwarf my 65". And I said that I insist on having the screen at the height where when seated ~ 10 ft away my eyes easily fall very close to being on axis with the center of the screen-just like when I watch my 32" 4:3 CRT TV from 10 ft away in my bedroom. Therefore, the bottom of the 65" 16:9 OLED TV in my living room has to be no more than ~ 13" from the floor, if that much.I really don't get how my sister and lots of people tolerate having to crane their necks upward to watch TV in their living rooms, but they insist on instead placing the TV on top of a credenza or wall mount it at some height that puts the screen's center well above their seated line of sight. NOT my cup of tea, thank you.

My screen is 55 inch. The bottom is 5 feet off the floor. I don't crane my neck upwards at all, it's perfectly placed for viewing from my recliner. If one's seated line of sight is low then said seat would be a straight back chair. I don't do straight back chairs. My TV sits atop an old entertainment center, which last housed a 36 inch CRT in the usual fashion, with the center of the screen 40 inches off the floor. I had to tilt my head down to watch it. When I got my first plasma, a 48 inch, it wouldn't fit inside so I put it on top. It was much better.
Mine is not a straight back chair. It's a Drexel upholstered swivel/rocker with an adjustable seat back tension.
https://www.facebook.com/marketplace/item/1147143526472378/May I ask what make/model of recliner-or its dimensions?
And laying down on it how far is your head from the 55" TV 5 ft above the floor?

I have a Stressless Consul. I don't lay it flat for TV viewing, although I do for napping. My viewing distance is 12 feet.
You need a larger TV. My 77" OLED is 5.5 feet away to give me the "Dolby Subtended Angle" of 45-50 degrees while my visual acuity with glasses, cannot resolve the individual pixels, so it's Optimum.
I can't go larger than 60 inch, the alcove where it is won't allow it, and I'm not going to put my chair in the middle of the room. No matter, I got along with the setup when I had a 30 inch CRT.
This looks wonderfully comfortable. https://www.stressless.com/en/products/recliners However, without open space around the head beneficial reflections may not be received, especially for music listening. I use the Drexel chair with a small ottoman somewhat like this so it won't block delivery from the main and center speakers. https://www.ebay.com/itm/404316098756

Mine doesn't block anything.
As for comfort, I spend some 7 hours a day on my computer. I used to do so at a desktop, sitting in a conventional computer station chair. It put all my weight on my hips, which killed my back. I went to Stressless and a laptop, the laptop on a table like this: https://www.homedepot.com/p/Karl-home-Height-Adjustable-26-in-H-W-Retangular-Gray-Wood-Iron-Computer-Desk-with-Wheel-941228127004/318312582
That ended my back problem. Between being on the computer and just watching TV I'm in my chair some 10 hours a day, with no ill effect.
"Troy informed me that he's no longer doing custom speaker designs and has now switched to only offering turnkey speaker systems."That might be a good thing, depending on what he means by "turnkey", as long as you like the sound of them - before purchasing and installation.
OTOH, when a contractor says he's going to do something, and then says he's not going to do it, that's a big red flag.
You might want to put him on 'hold', and start shopping around for a different contractor.
