4" Full Range Transmission Line - Aucharm speakers

Looks great, I haven't had a steady enough hand to do such in at least 20 yrs, but would need an A/B comparison, though from long experience doping drivers it falls in my airbrushing category of being too subtle for all but the thinnest, limpest, diaphragms, etc..

I've still got a few of these and other once popular 'el cheapo' 'FR' drivers and if I can ever get back to DIY audio before my body completely gives up, I want to literally steam the starch out of some for further experimentation.

Thanks GM. Was hard to build, first time working with wood and using only a circular unstable marble saw. But I'm really impressed with the result. Thank you so much.
I use polyfill fiber to stuff but I think still missing some bass. Still there any possibility to tunning more the bass?
