Thought I just share some of my recent edits to previously posted unfinished projects after some time of little activity. I guess this is what I love about DIY, mixing up projects, endless mods and learning bringing in new ideas, enter/exit whenever time allow. For some background I have been obsessing with building retro 12" 2-way coaxials and 3-way monitors ala Tannoy/Heresy/JBL inspired stuff based on cheap PA drivers like Eminence, Fane and Celestion for half a decade now. These projects can be found here - might be interesting to some thinking about the same:

The first few projects was not good, the boxes was too small and Ive struggled with crossovers and what not. The more recent projects are more successful yet I see the need to enter DSP to get any further with coaxial especially. I also struggle to make good cabinets so these are all still pilot/prototype projects until I find decent material and get/learn better tools. I do like the Celestion project still, this is in my studio to come. My last project was suppose to be a Heresy inspired 3-way construction with Fane drivers but it ended up being a two-way with surprisingly good results and has been my go-to sound for the last year or so.
Fast forward and I just bought a house with basement that I plan to build into an audio asylum. Last week I took the last Fane build and removed the bass driver (to be used in a future project with a 5" mid for a 4319 inspired monitor) and installed the Eminence Beta 12CX/PSD2002 coax combo instead from the first mod thread. The Eminence flares APS150S and APT50S are fitted with ASD1001 and APT50 drivers. Plenty of options to play around with HF but not connected as of now 😉
The EB12/PSD coax combo sounds very powerful in this box with the Eminence CX crossover. Still 2-way. Not sure what do with the disconnected HFs - maybe some supertweeter thing, I'm still working on rear ports and terminals and damping, will keep you posted about the results but finally I believe I get the max out of the Eminence drivers I bought years ago. The poplar-plywood is crappy so I might build a new box or find a way to make it better but I think they look kind of cool as well in this chabby basement as of now. I'm also surprised how dynamic it sounds with open back rear baffle removed for cutting. Maybe a dual 18" OB sub is the next project for this basement?
Hope the random thread are of some interest. Ideas are welcomed 🙂
Oh and if someone know how to remove the "Fane equiped" stamp without ruining the MDF paint please advice as this is just wrong now, this is a pure Eminence atm 😉

i would choose black duct tape or black paint over the fane sign
have you tried out any other coaxials drivers?
for high frequency horn, try out the dayton audio clone of the jbl constant directivity horn, it sounds very good, should work with your compression drivers

I have tried the celestion 12” but those are not finished either, need some special attention to crossover or I might go active with those (see separate thread). I am considering replacing the beta 12 with the kappalite coax some day. But I want to get the max out of the ones I got first. I’ll check out the dayton thanks!
