Hello,
I am looking for plans for a cabinet to fit my Scan-Speak P17WJ speakers. I have recently built DDVP-20 cabinets for my Visiton BG20s. I loved the bass and would like to get a similar sound again. Can you suggest a model I could make? Thanks Very much.

Thank you both for this information. It's not exactly what I'm looking for but it is very interesting. Thanks!

Forget it. Standard Classical Design which is not at all good.

Regarding that vintage Danish design. I have listened to it using several drivers ranging from a 4" Altec Lansing A405 to 6.5" Philips fullrange and it sounded surprisingly good. I am sure a modern massloaded fuzzy TL with internal resonators and optimal placement of driver and damping material is way better.
Make an adaptor plate and mount the 6.5" driver in the DDVP-20 cabinet that you have.
If you like the result go for an identical cabinet or scale all dimentions down by about 6.5/8. You can also go the simulation route, and try out endless designs in silico.
