I looking for a 8” woofer to go into a sealed box app. 45L . I would like to spend $100. Or less per .
Looks good, and price is right. Really want to stick with a 8”. I would like to keep width of cab.,to 11.5” overall.,

11.5" are 29cm. You will find a lot of 10" woofer that fit that baffle and work with the large volume you got. If you got the volume, use it.
You may tell a little more about your plans, because the woofer should not have more SPL than the other 2 speakers. Do you know how to do a crossover? Maybe do a search for "3-way speaker" or the like.

11 5" width works with the SB26SFCL38.
You will have better sonic results than a 8", 346 vs 220 cm2

The SB Acoustic SB23MFCL45-4 is a great driver with large Xmax and low distortion. NOTE this is the 4 Ohms version - do not get the 8 Ohms version. It's about $150 though.
45L is a bit too much volume for most 8 Ohm drivers so overall the Q will be on the low side (drooping response). For example, in 45L the SB driver has Q=0.45 with F3=61Hz, F10=27Hz. You could add 2 Ohms series resistance to get Q up to 0.575 and then F3=37, F10=22Hz but sensitivity will go down from 88Db to 85dB at 2.83V.
As others have posted, a 10" driver will likely work better in 45L...

My personal rule nr 1 in loudspeaker design, always start with the biggest woofer you can get away with. A good fundation is very important as it improves your mids, highs and stereo imaging as well.
I like this as an old school 3way, but really want a sealed box. Of course nothing is written in stone.,

Morel MW 266 is a good candidate for a sealed cabinet. PE wants 166 bucks for it.
You really need a woofer with a Qts of near 1.0 for that size sealed box. GRS 8PR-8 ($14) would work in 25L, you could fill with some wood blocks to reduce volume. Goldwood GW-8028 ($32) may work too but works better in a 35L box.
Back to 10" and you have the Peerless SLS 10" 830668 ($60) would enjoy a 45L sealed enclosure with F3 around 47Hz, the 8" version works best around 28-30L.

Eton 8-412 would suit, but sadly too expensive.
An alternative might be the not fancy Monacor SPH220HQ. Not sure if easy to get in the USA, but can be ordered from https://www.soundimports.eu/en/monacor-sph-220hq.html
Looks like qtc of 0.65 and 45l gives an OK f3 54hz, f6 40hz.

Thanks, but the box volume is not fixed. I see the a sealed box woofer is going to be hard to find.
It isn't difficult to find a unit well suited to a sealed cabinet, but it is more difficult to meet your expectations.
Dayton RS225-4 and RS225-8... both will play nicely with an 800 Hz crossover. They have low distortion, and reasonable Xmax. They are in your price range.
RS225-4 in 45 liter sealed box: 4 Ohm, F3=59 Hz, F10=29 Hz, Qtc=0.59, sensitivity (2-pi) = 91 dB
RS225-8 in 45 liter sealed box: 8 Ohm, F3=57 Hz, F10=27 Hz, Qtc=0.57, sensitivity (2-pi) = 87 dB
You could use any box size from 20 to 50 liters with only a small change in bass performance.
I recently used the RS225-8 with a passive radiator, and I thought it was a very good value... A high quality speaker for the money.

I would really like to keep the cabinet as small as possible. Using a passive radiator is not a bad idea. Right now I just putting a concept together. Cost is one aspect, getting so decent sound is the main thing, of course, but I don’t see why using decent low cost drivers would not work. I have some Cambridge soundworks model 6s , not great , but very comfortable to listen to. I don’t think the drivers in them cost much, but they are well thought out, for what they are.
I am gathering information right now, and looking at what others have done. I have no intention of rediscovering the wheel. They will just be another rendition of the old three way “ book shelf” , but will live on stands. Looking for f3 around 40hz
