The TB bamboo cone driver is a longtime favorite and this TL floor stander is my 3rd and most ambitious effort. A rear ring radiator tweeter adds some air and opens up the stage. This tapered and progressively damped line allows this driver to shine, giving clarity and resolution that competes with electrostats (I was a MartinLogan owner for 12 years) but with no crossover or transformers in the way. My Odyssey mono blocks love them.
Maximum LF definition and clarity in a domestically tolerable form factor.
Tang Band 4-inch Bamboo Cone (ferrite version)
Vifa Ring Radiator Tweeter (rear)
Dayton 5K HP filter
Tapered and progressively damped 12-foot transmission line.
Poplar baffle sandwiched to MDF with MDF internal baffles
In my big listening room these guys get subwoofer help but in a 9×12 room with corner loading they’re stunning.

“Domestically tolerable form factor” I know what you meant. That’s funny! Great job also!
There is no “Vifa Ring Radiator Tweeter” in your parts list, nor are there any pics indicating tweeter placement. I hope you amend your post to provide these details. I’ve used the W4-1320 in projects and love it’s capabilities. I’d love to see more that you’ve done with it in this one.
The Project Parts list does not include the “Vifa Ring Radiator Tweeter”. From experience I know the W4-1320 is a very capable driver. A cabinet schematic and an indication of how the tweeter was implemented would go a long way toward helping others realize the merit of the design. They sure look nice.
