Dedicated Music Room Recessed Lighting (High Hats)?

Sounds ideal to me.. One of the rooms is 15X20X8 with built in closets 3 foot deep. BASS traps, sub placement and equipment placement. 3 32" wide pocket doors.  That's the plan anyways..

It makes the room, 15X17X8 same size... :-)

It's not just old style LED's that make noise. When I built my music room last year, I tried out some fixtures that stopped radio reception. God knows what it was doing to the AC line, and I didn't want to know how it was beating against signals in the audio chain.

FWIW, I use only quartz or tungsten lighting (that is, strictly resistive) while listening. The LED's are there strictly for maintenance or when the room is used as a study.

I had good results with Quietrock 545, but it sounds like you're past that stage.

bkeske, I didn't specify the LEDs to my electrician. And I just had him put in six 3" LED "shallow" lights in a fireplace bookshelf surround. Unfortunately I wasn't here when the cans went in. So, now I'm going to take the cans out and replace with the LED shallow solid fixtures.

Good idea. I’m an ‘older fart’, and dismissed the new technology early on, for good reason IMO. Heck, I’m one of those guys who bought 2 large cases of incandescent bulbs before they became ‘outlawed’. Since, I’ve actually replaced all the bulbs in my home with dimmable LED’s recently (all very ‘warm’ bulbs that mimic incandescent). I’ve become much more accepting of the new LED technology and their benefits. The shallow LED lights are actually pretty nice for a variety of reasons, and will reduce almost all your sonic concerns.

In terms of sound deadening drywall, ‘sound insulation’, and the like. Yes, those products might have some effect, but it is rather small. The science and technology of creating a true sound dampened/diffused space for high end audio takes a lot more than simply  utilizing those types of products. Check out Acoustic Fields on YouTube. That guy knows what it takes to make any significant impact in a dedicated listening room.

Just finished up my listening room and using led 2700k cans.  Airtight unlike the old style cans. Good dimmer and you are good to go
i have a couple of cases of green glue and s few tubes of acoustic caulk if you need them.

From an architect:
I don’t know about physically/mechanically buzzing, but if you have not already done so, wire the cans on their own circuit.  Especially important not to mix LED and incandescent on the same circuit.  Separating the can circuit will allow you to change dimmers, and troubleshoot if you have problems.  Matching the dimmer model to the cans is important to keep them from buzzing or flickering.
