In Reply to: RE: SEAS A26 Woofer posted by cawson@onetel.com on December 21, 2023 at 07:59:21
Good info that I already knew. But you ignore the main point. I want to build a 2 way without a low pass on the woofer, preferably one that works in a closed box. The important factor is no crossover on the woofer to eliminate the reactance of a crossover. The A26 woofer works but I would like to find something even better. I have searched lots of manufacturers and nothing quite works. There seems to be a Morel driver but it's ultra costly. And there's a SEAS nextel 8 inch but it rolls off too high.
Follow Ups:
You might not find any others and it might not be work so well if you do.
A modern 8" two way in a tower is hard to beat in a normal household living room. Snell E 4. Dayton has some decent 8s and even a 10. Adding the Wavecore TW030WA12 around 1500 for great results. A DIYer can even get Xsim files for both and tweak crossovers till they pass out, finding a design to maximize (compromise) impedance. Furthermore, there are several independent measurements for each to confirm published data, response and distortion.
Anything more is more expensive and complex and maybe only a little better. Anything less will compromise something.
Although aware of the Wavcor brand but have no experience with either.
The TW30 is interesting for bigger size low Fs type projects, have you any experience with either company or driver ?
Maybe a line or url for a Europe based DIY forum with Wavecore experience?

Yes I use the TW030 in a project. I like it alot.
Been tossing around for a larger dome low fs tweeter, most are 34 or 35 mm and so I associated the 30mm Wavcor n that group , but it's just 1mm more than say the Scanspeak 29 series and some SEAS.
Funny that 29 is small, but just a 1mm larger 30 is big.
Thanks for the experience shared
These tweeters cover a lot of bases: Wide range > 1500, low distortion <.5%. smooth response, 92DB or more and decent wave guide off access. Hifi compass and Voice Coil Test Bench verify the numbers. I think they sound great. I like the JBL 2431 slightly better and the SEAS 27TDC (no ferofluid) slightly less. I got rid of everything else.
