My current setup is 4 ceiling hung 2x2 styrofoam DML panels + a sub + heavy EQ. It sounds good, but is very inefficient, and with the panels' LFE ending at about 200Hz the bass is uneven throughout the space.
I want to replace the panels with conventional drivers slim enclosures. I want to keep it simple and cheap. For the tweeter I am debating using a compression driver without a horn as those seem to have great dispersion. But I imagine the overall sound is harsh. So any recommendations are welcome there. Then for the woofer I think a 6.5-7" driver will be fine. I'm just unsure of whether to keep it simple and go sealed or add a passive radiator. I mainly listen to music from the 60s-80s so rarely anything super bass heavy. I'm looking more for clarity, response and better efficiency. I'm OK with doing a little EQ as well but nothing crazy. TIA

Jbl 2142 if you have room ( check the depth) - 97db @1 watt - cheap on Ebay -
I did a room with 8 of them and subs, really nice.
Now doing 24 of them and 4 x 18 subs in 1500 sq foot - really, really nice …………. No one who works there wants to go home, they stay late and play music…it’s that good

For OP
With a sub it opens options.
8" is rather standard ceiling speaker. If high efficiency can start getting up to 92 maybe 97 dB
tradeoff is less bass. But the sub changes that.
Higher prices include mentioned JBL or B&C the budgets typical PRV and Lavoce
Likely lean towards PRV on budget side.
Very cheap be Goldwood or many others. Those will be typical high Qts ceiling speakers. Bolt it to the ceiling and done. High Qts so no box usually, ceiling is the baffle of course.
Group of Photographers back in the Mall days. Great Friends and good memories.
Have a feeling the environment you created might stick with them , many years from now. Sub at work? Geez
Sounds good to me.

Nice! pretty cool story, best memories was removing the " corporate approved" CD's at work and replacing with our CD

It’s not whistle while you work at our place, not when you want a little reggae. We also have 4 way 7 foot high old school JBL in our other shop - 2 pairs of them with 21 inch subs, 2 x 18 inch woofers, 12 inch mids with bullet tweeters in the mid cabinets, and the yard wide lens with 26 pound Alnico midrange drivers - nice, but you can’t mount 1800 pounds of them in the ceiling.

I prob wasnt clear enough about what I'm building/what I have. Heres a Reddit thread I made with a video
Basically, I am looking to build shallow enclosures that will sit flushmount on the ceiling. So no cut outs. This leaves me a lot of freedom with driver choice.
I do like the idea of a coaxial, especially with its own crossover. I just want something that will pair well with a 1 cu ft enclosure and maybe a PR, though I am OK to sacrifice some low end for better accuracy. That JBL looks interesting but the recommended enclosure size is too big

You can mount the JBL driver ( or other coaxial) without a box, you just get less bass from it, but with a separate sub you can work around it.
Here’s 3 of the JBLs on open baffles, not that you would mount yours that way, but to show they can be used without a box. There are floor mounted 18 inch subs ( and more of the 2142’s on open baffles ).
It doesn’t seem like it would work until you hear it.
The system with 24 of the 2142 are all on the same open baffle mounting - and more subs

Just checked the price on those JBLs- way out of range! I need 4 of these, don't want to spend more than $100 per channel on the drivers (and passive radiator if necessary)
I didn't consider going OB with these though. That would simplify things a lot

you won’t use passive radiators, not many around and they only work with boxes - your budget won’t cover what you first had in mind.. Just mount coaxial drivers ( maybe car drivers if you can’t get good used industrial ones) in the ceiling with no box and no radiator, maybe experiment with some fiberglass around the back of the drivers to increase bass a litlle and reduce reflection. You won’t get deep bass without separate bass drivers - forget passive radiators . The 24 JBL coaxial drivers on open baffles with subs are being installed in a 1,600 sq. foot workshop in Birmingham, Alabama, with about 2 Kw to drive them. We high pass filter them at 115 hz with a big polypropelene capacitor so we don’t overdrive them in the bass region without a box. We got a very good deal - paid $110 a driver plus shipping for used 2142s. If you're ever out that way let me know.

Interesting makes sense. 1 cubic feet for 8" little on the small size.
Probably pushing to a 6.5 inch. A driver that would work in a small box will need low Qts around .3 they can get spendy just because low Qts is usually rather healthy magnet.
Staying with healthier bass idea Dayton does have low Qts drivers in 8" I wanna say the DS215-8 is one. And just do a 2 way
Crossover be typically around 1200 Hz for a 8" so your looking for a larger tweeter 1"1/8 so the RST28 will work right along with it.
I think ported be easier, if you want to do passive radiator. Dayton actually has matching radiators for DS series woofers.
Fs for the powered woofer is 34 Hz would basically just calculate whatever weight needed to be 34 to 37 Hz.
Far as I remember last time I simmed one it didnt need weight. Was ready to go. Ironically I think a actual alignment for that woofer is around 1 cubic.
Low Qts makes it possibly. Rather healthy magnet for its price.
