A thread for Tysen and variations on FAST - Page 17

Our next project based on this concept playing in my office today.

Woden Design's Twin EL166 ML-TL (with my own variations). Executed as an MTM with an FF85KeN. We started this one before FF85 was discontinued, you could use your favorite mid-tweeter -- i think Alpair 6M should be a good candidate -- or a tweeter of your choice.

Lots of good well controlled bass. Even thou XO work is still at early stage, i am quite happy with them.

XO work...rather you than me, mate. Dancing ballett while carrying sacks of coal and paying for the privilege?

Fortunately in the 250-400 Hz range and i'll be able to get away with 1st order so not a lot of degrees of freedome to deal with.

hey Dave - besides that new project - got any F.A.S.T. suggestions for a reasonably compact speaker to play the odaiko-stuff at heady spl? Seems (?) like it'd have to have the fullrange move less than the woofer to survive indicating 2nd order highpass. -got a Trio12 in my pile.

Another FAST-related idea I've been kicking around is to update vintage boxes with a fullrange + woofer setup.
Could first-order passive high and low pass filters work with the right driver combination?
If the fullrange drivers are used with said high pass ~ 200 Hz, could they share a 1.5 ft^3 sealed cabinet with an 8-10" woofer?
Just rudimentary musings -- sorry if this is categorically not in line with the FAST philosophy.

I've had 1540TBX woofers laying around for ages - maybe a sealed/"boosted" with cap for the woofer and Faital 4FE30??? I like this little Faital for its cost and sound but don't have experience with other 4"

spare woofers - higher mms, lower vas, moderate sensitivity

500uF effect (assuming low drive Z)

maybe 15TBX is too loud for this application? - in a little reflex its 3-4.5dB lower in sensitivity than a strong woofer with half its moving mass making it 7dB less than the JBL in a Karlson

Factory spl and Z

I have commented & shown more pictures of these in other threads, they turned out VERY well.

Here is the XO we ended up with.

The new FF85wk should drop right in.

Here is a visualization of the next iteration of "Tysen", with the new FF85wk augmented by an ML-TL with 2 Peerless 4" (thanx Scott). The little uFonkenSET are already in play and quite stunning, the Peerless woofers are on the break-in bench.

Sounds interesting Dave - why this choice of woofer support ?
