I am looking for the best full range driver... I know "best" is normally a subjective term, however what I'm interested in is a driver that meets the following criteria:
1. Low cost (maybe around $100/driver?)
2. True full range (like Loather) 30-20k or very close
3. High efficiency for a low power tube amp (3w/ch @ 8ohms)
4. Low Qts for a horn design
I love Lowther, but they are expensive for me. Because I am on a fixed income. Any help would be awesome. Thanks

Look at Fostex drivers. They're well regarded in the right enclosure, such as horns. Mark Audio drivers are great, and I believe some members have used a BLH with a low power tube amp with a lot of success.

yeah - just the stock FE206 - they've crept up to ~$118 each at Madisound. I like the little 6.5" L Cao but its high Q motor will take a different approach.

It doesn't have to be a low Q unit for a back horn, although since you mentioned a 3w valve amp with a presumably high output impedance it's probably a good idea.
Anyway, what was said above; in roughly that price range the FE206En is probably the obvious choice, and shares some overall characteristics with Lowthers.

no best - period, and certainly will be tough to meet all 4 items on your list - unless you stumble upon a "garage sale" price on something exotic
of significance in shortening the list of candidates likely to meet a reasonable compromise might be - exactly how large a horn were you anticipating?

Doesn't meet the $100 cut-off but what about the Dayton ps220? Check out the Singularities for some ideas.
You mean you just scale the horn to fit the Qts? Like a big vent reflex-ish thing?
Slightly of topic tangent I know, but I always wondered this: Fostex off-axis plots always have three readings. Two solids and one stippled. Are the two off-axis ones 15 and 30 degrees as standard? Anyone know?
Well, you ideally design for the actual system Q rather than just the bald driver Q itself. So if you stick a mid - higher Q driver on the end of an amplifier that already has a high output impedance, watch the necessary cabinet [horn] size rocket.
Re the Fostex plots, I think so but don't quote me, I'm still not firing on all four.

One solid, two stippled
...........appears to be based on other brand's documented plots.GM
I have the Betsy K and like them a lot. It's not the end all be all of fullrange or extended range drivers but quite nice for the price. If you want to order them I suggest going into the vendor forum and contacting them via pm as their email on their website didn't work the 3 times I've tried.
The FE166En should also be considered. A bit less expensive, won’t go quite as low and isn’t quite as efficient, but the horn for them is a little less imposing (for FE206En, for FE166En). We recently built a set of Victor & used FF16wk. It is figured to out perform FE166En (and FE166eSR) in this enclosure. A bit less efficient, a bit better bass.’

I was rethinking the horn thing... I was checking out the OB designs and listening to a comparison on Youtube, and I am thoroughly impressed with OB. I NEVER thought OB would sound like that. I am sure I would need more power though (even with that fairly high efficiency of the Betsy(K) than 3W/ch... does anyone else have an opinion on that?

Hello there is no best driver,
over my 40 years developing,
i found the SICA 208.38 1100 will fit your need.
