Having heard Vifa dual ring radiators (XT19/25) in various speakers, I'd love to build a speaker around them.
Being a Tannoy nut, and also due to being a first time speaker builder, I'd like to only build a full range 2 or 2.5 way design. There are a few DIY pages out there using this tweeter, but mostly bookshelves or three way designs. Due to my main listening room being a bass suckout and my other listening room being on the large side, I'd like to build a large two way. This tweeter doesn't typically like to go low. But according to a thread here, by using a 10-12" waveguide it can supposedly go down to 500Hz, making it usable for a larger two way.
Now the difficult part, finding a woofer that it will play nicely with. From my limited knowledge, the Peerless 830669 may work: http://www.tymphany.com/830669
Now, I'm not sure if I want to build a open baffle or ported box. I helped build the 200 liter cabinets for my Tannoy HPD's and recently veneered them myself, so I have some experience with building. But the thought of a waveguide and 1-2 12" woofers mounted on a piece of 1.25" thick MDF veneered with zebra wood...
Thanks,
Mike

A large woofer will beam, so it depends on how you do your listening - sitting in one place or moving around.
A design like this (2.5 way despite the number of drivers) will probably give you better sound dispersion in the room.:

(the Mark 1 uses the tweeter you like)
I suspect your bass problem will need to be dealt with separately, though, using a separate judiciously placed sub and/or room treatment. It would also probably mean that ported would be best (for efficiency reasons).

you've probably seen my thread 🙂 I use exatly same drivers.

it's more like 700hz crossover point.
you may do some research, if you don't already own these drivers. I think there are better options for ultimate two way speaker 🙂 take a look at Gedlee's or sp technology speakers.

MisterTwister, I tried to send you a email, but the forum won't let me.
I read your thread, but didn't catch that you were using the same woofer. Just curious, why aren't you happy with your setup?

To be happy with this 12" driver, you should add a 5" driver to handle the 500-2000Hz range. A SDS134 or a HDS134 will fit very well. The SLS315 should works in a 70L closed box. http://www.tymphany.com/830669-app-note. Don't forget to put a RLC on the SLS315 to suppress the 2kHz resonance peak.
I've made an OB with 2xSLS315, a SDS 134 and two DX25 (one rear) and I'am very happy with this setup. It 's works extremely well, but very difficult for me to tune it correctly.

You could use a wideband/fullrange driver with the 12" peerless, instead of the XT25, or use the XT25 as a supertweeter if you like that idea, but then I think XT19 sounds sweeter, but maybe not as "clean"
Btw, Accuton makes 2" tweeter that may do what you want, and theres may be a new better version with more topend coming
Also Tangband makes a 2" and 3" dome mid

Face, I am very happy with these speakers.
I meant there are better drivers for this kind of setup: lambda woofers and scanspeak tweeters 🙂
I know it's hard to believe, but this tweeter has no problem with such low crossover point. of course it's not extremely high spl speaker. sptech has dome tweeter crossed over @600hz....
