ScanSpeak 2-way with waveguide

[nicoch58]

the 15w is really wild on bass I use from 2001

Interesting, as ever, Goran! 5" plus 1" seems to be the only speaker with enough overlap on driver response to get away with LR2. You've given it a decent sized box too. Most speakers like this are too small IMO. Lumpy bass is bad. 🙂

I'm seeing huge interest at this forum in the Earl Geddes type waveguide currently. It solves the time alignment problem one way. And matches dispersion too. I'm thinking that SEAS DXT tweeter might also be good too in this sort of speaker.

You start to appreciate what designers like our own tinitus (RIP) aka Lars Dyreborg and Duke LeJeune are up to here:

My Intimates speakers uses a very similar SS bass/mid with different last initials. Mine is the K01 version with the coated cone. It's also housed in a PE curved 15L cabinet and has listenable bass down to 40 hz. vented.

Those SS 15W's sound like amazing drivers to get listenable bass at 40Hz with a 5.5in woofer. Although the factory recommendation is 55Hz F3 with a 10L box.

I carefully follow this thread.
I still have 4 pieces of Dynaudio 15W75-4 (formerly been planned for the car).
For years, thinking what to do with them 🙂
They are not the same, but similar to the SS 15W.

I might get some idea after your posts 😉

V nice design. I've got the same SS units/pair of HDS tweets which I thought to waveguide (to help tame above 10khz)
