Not sure if this is the correct address to post but was looking for some recommendations for some in ceiling speakers that will provide near hifi sound (if even possible) that will be driven by one of the tpa d amps else where on this forum?

I can't see a reason why it is not possible. If it is what you want.
But ceiling will need some kind of reinforcement... Or you can go the Bose way... so you have to provide subwoofers (not on ceiling of course). This will improve the sound considerably. More subwoofers are better. The key is to integrate the subwoofer with the room (and the small and not so important midrange drivers).
And that impedance issue... why most ceiling use transformers... is not really an issue...

I do not have a very large budget around 1-200 dollars. Would I be looking at two way speakers or full range? Anyone have some suggested models. Also not sure what was meant with the comment about ceiling speakers using transformers. I am new to this and ha e just purchased based on what was on sell not knowing what would be the best way to go. I did this in my living room and do not think the sound quality is very good so wanted to do something better for bedroom.
I think "ceiling" speakers can mean different things. In a multi-storey building, the building management will implant speakers on ceilings for public address purposes. There are many speakers, and there are long cables... TOA and Philips are the most common brands... with impedance matching transformer of course...
Another example is in large supermarkets where the ceiling speakers are mostly for background music...
In small cafes, Bose style is more common (sattelites mounted on ceiling plus subwoofer)...
Or at home, ceiling speaker is not so different than in-wall speaker, taking advantage the infinite baffle and minimum reflection...
Okay understand, I am talking about in-wall speakers for home use. What would be some good ones to use or how can I determine which ones to buy?
The difference between hi-fi in-wall speaker design (not the one for public address) and ordinary design is that in in-wall speaker no bass signal is going backward. This should be taken into account in crossover design. The implication is:
(1) You cannot put ordinary 2-way design inside a wall, without removing BSC component of the crossover.
(2) Full range drivers, you may check their frequency response. I think most of them will need some kind of equalizer. May be you will need to find ones that is flat in infinite baffle if you don't plan to use equalizer. Unfortunately not many design example here I believe.
In-wall design is not flexible, but for small bedroom I think it is a good idea to prepare holes in the wall and an ordinary boxes to be fit in there. If there is a 2-way design with dedicated BSC circuit, I think it can be used by removing the BSC. Otherwise you have to design the crossover by yourself.

for mounting in a suspended ceiling, the following might be ok using a decent auto 6x9" coax - a mockup could be made of foamboard or cardboard

I have a pair of these :
Dayton Audio ME820C 8" Coaxial Ceiling Speaker Pair
on 2' x 2' open baffles ......
I enjoy them very much . They are Fs ~60 Hz and Qts ~0.6 thus need some bass
boost on the OB but can handle it to louder than I usually listen .........
I have also had 2 less expensive ones work well in a sealed box :

Those Daytons are supposed to be nice. So are JBL Control 328C. A firend of mine who's in the installation biz swears by top-of-the-range Speakercraft.
...or DIY like I'm doing 😀 Made a sort-of Speedster with TB W4-1720 + OWI-92 active with a TPA3116 in each in a vented 4.5 liter box for each of my two daughters' bedroom. Source is a mini-PC (MiniX Z64) with a decent USB sound card running Spotify (controlled by their resp iPhones) with JRiver's WDI driver for output so I can use its DSP for XO (built-in IIR or convolver with FIR). Took the plunge rounter to the plasterboard to countersink the drivers neatly - dusty as h*ll 🙂
Will be doing another one for my son's bedroom next with 18sound 8CX400 with CD10Fe as replacement CD in 10-15 liter and a THAM12 as sub 50-130hz as there's a loft space above his bedroom.

I’m looking for some ceiling speakers for my kitchen. I’m not expecting the highest fidelity, but I want the sound quality to be decent. In the years since this thread was active I’m guessing things have moved on a bit. So I’m looking for recommendations . . .
Traditionally, ceiling speakers were paper 6-8" corrugated surround drivers with a whizzer cone. Museums used them a lot for audio-visual. Sometimes with line-output transformers to daisy chain them.
Quite a good choice of modern equivalents here at Impact Audio:

Take your pick. I wouldn't throw a lot of money at them. But a good solution for a kitchen, I'd say.
