My next project is going to be a two way in a sealed enclosure using a 5-6.5” (probably poly) woofer. What are some of your favorite tweeters for under $75, $25-$50 is even better?
Thanks,
George

Stock tweeters:
SEAS DXT if you need to cross low, XT25 if you do not.
The Peerless DQ25SC16-04 also sounds great if you need really inexpensive and would probably sound even better on a waveguide, although I'm not sure how well it would mate to one.
Modified tweeters:
XT19/25 on waveguides (will obviously cross much lower as a result).
The D2608/9130 sounds good on a wave-guide too although comes across as a bit brighter due to bunching (loss of directivity control) in the off axis in the top octave.
I haven't tried the SB26ADC tweeter, but on paper this looks like a no brainer, waveguide it for something better. It'll cross very low and basically do whatever you want it to do (within sensible reason).

The DXT is a tiny wave guide so it doesn't maintain pattern control very low. Realistically you only get properly controlled directivity from about ~4kHz and onwards.
The guide itself shapes the response well below this, adding in the extra output down low that allows the tweeter to go lower than you might expect.
The idea with the DXT is to really cross over before pattern control starts, where both the woofer and DXT are omnidirectional. Then all narrowing of directivity is handled by the DXT alone giving a smooth end result.
You could of course cross the DXT to a 4" woofer at ~4kHz for a good directivity match but that'd really be a waste of the DXTs capabilities.
Xt25 is my favorite tweeter too, far better sounding then dx25 and the hds-tweeter.
Another favorite is s-s 9300 but at a higher cost.
if i was not short of money i would buy a bunch of seas excel t25cf001

I've just acquired newest incarnation of SB26ADC and sadly, dome and voice coil is adhered to frontplate so kinda disappointment for waveguide conversions..
I had the same problem with the Transducer lab N26CR2A. Perhaps a transfer paper to mark all screws and then transfer them over to the waveguide for cavities to be predrilled might work but I gave up.
Mark K's ER18DXT crossed the DXT at 1500Hz LR2 acoustic slopes. Very drastic XO, but the horizontal directivity match to an 18cm/6.5-inch driver is exemplary and the vertical dispersion great for a non-coaxial speaker its size. He has the tweeter tested to 105dB/1m to make sure the tweeter could take such a slope. The XO used to achieve the target LR2 rolloff is not so much a high-pass as two notch filters (details in his build log).
Could you guys please clarify which XT25 that you are recommending:
XT25BG60-04
XT25SC90-04
XT25TG30-04
BTW, as far as a budget tweeter is considered, I like the DQ25SC16-04 in one of my recent builds (Zaph Audio favorite).
Thanks,
George

Let me throw in an out-lier. The Alpair 5.2 (or FF85wk). I am not a big fan of dome tweeters, and like a really low XO.
We have done a 2-way with FF85 and 2 5.25” Silver FLute W14 woofers in a Woden TL — it has very good performance.

Not at all.
Don’t forget that both the drivers i mentioned have 18-19mm dustcaps that act as super-tweeters.

My fav so far is the SB Acoustics SB26STAC-C000-4 for around $42 or it's smaller faceplate neo brother SB26STCN-C000-4 at $33. Nice crisp, clear, open sound.

I agree that the XT series are all fantastic. For low xovers, the DX25 is hard to beat for the price.
The RT1C-A is good, but can't xover below 4.5k. I prefer the RT1.3 for use almost an octave lower to 2.6k.
Peerless DA25BG08-06 is a very nice tweeter.
I hope the new Peerless TX series is phenomenal, as I have the 32mm to try.
SB26CDC does sound quite good. I heard it in JeffB's Ceramicos before it was even released.
Airborne (Hygaeia) RT5002, a phenomenal AMT, but slightly above your $75 limit.
ND28F-6 is a smooth tweeter, and inexpensive, and can xover at 2k.
Vifa D26NC56-06 is a rebadge of the old D26NC55, and it had an incredible reputation.
CSS LD22F is a great 22mm that does what most 22mm won't.
Most of the Wavecor line is under the price point, and they are all smooth sounding, but the FR might have a few wobbles here and there.
Can't go wrong with the MDT30.
...and I can't stand the DQ25.
Dust-caps as super-tweeters? Sorry, but that is breakup that needs destroyed.

In fairness, a central dome of a wideband driver that is direct-coupled to the end of the VC should be the least resonant part of the driver in question. They can in fact work rather well. I like and use conventional tweeters also of course. And in fairness it's worth pointing out that ring-radiators, which don't lack for fans (I like the Scan versions of the XT25 and the Satori TW29R myself), are not exactly functioning as pistons either.
Throwing a couple more into the mix, the evergreen Seas H1189 and H1212 are familiar and conventional but still excellent units, even though they've been around for a while, so they are always worth considering.

Can sound "bright" depending on how it's integrated in the design, particularly in contrast to the partnering mid-range/mid-woofer. It sounds like a good monopole electrostat to me (with far superior dispersion).
Not the best for a low-order and extended/low "slope" high-pass, but still good for a lower freq. (down to 1.8 kHz) high-pass with the right filter in the right design.
If you want something that can handle more extension look to the Aluminum ADC or CDC from SB. ..or: for larger waveguide-use look to the Scan Speak D2604/ 833000.

-and while the linearity doesn't look great, it's not bad on a typical (8"-9") narrow baffle.
