Im not sure about this carpenters? since speaker consist cabinet, driver, crossover, ... I see some project with cardboard cabinet but if U educate yourself a little bit more, u can find that is one favorite HI FI company make cabinet and after that make drivers to adapt to this cabinet (to help U, at first company make just drivers, now U can not buy drivers, only complete speakers)
Ill attach scheme , pict and impedance dia ...

Last year at the Munich Fair I was impressed with boenicke w5, but unfortunately price is bigger than my limit , especially SE version
Since we have design studio and 2 CNC machine (for other purpose) I tried to do it something similar, but way is more than complicate since need to make holes on 3 different side s
No meter, if not counting our time, material, drivers, crossover and rest is almost 20 percent of price of W5SE
After I test it, sound is more than awesome
Here is couple pict from production process
BTW my workmates is also make pair for him, and we order material for one pair for our office 🙂

Nice work!
Would like to do the same build. I'm an audiophile/woodworker. Do you have pattern or cad file? If so, can you share or send to me.

I would also be interested in the xovers, drivers, wiring, and damping material. How it was assembled. The full build.

Thx

If anyone is interested, I’ve made 3D models of these in Fusion360. I can share the stl or fusion files. I’ve printed them in 8 parts and I’m just waiting for the crossover parts to arrive.

Hello Stramer,

Not sure if I can answer your question directly here...............
I basically use the crossover schematic shared by Etonis on post #6 of this thread. The components I use are

For the FE85's band pass:
Obbligato gold premium 10uF
Panasonic EZP-E 12uF
Mills MRA12 2.2ohm

For the tweeter high pass:
Obbligato gold premium 2.2uF
Mills MRA12 10ohm
Mundorf foil inductor 0.12uH

No crossover for the woofer...

Do note that I lack the technical training so I am not able to tell you what are the crossover frequencies.

I first tried listen to them without crossover and without the rear tweeter, the highs were just "incomplete". Then I install the tweeter with the high pass filter, but without band pass for the FE85, the highs were ok but somehow I just cannot listen to them for too long before getting a headache :-(
Finally I connect the band pass for FE85s and they sounded so much more pleasant to listen to.

Unfortunately I believe I have problems with my room acoustics, and that my refrigerator in my small little apartment is humming at around 65~80Hz, the low frequency somehow resonated too much and was rather unbearable. So I finally sealed the tunnel port and now they are lovely to listen to, the bass are very sufficient and full in my apartment and they are fast and punchy too.

Hope the above helps a little.

Have a safe Christmas.

Bandpass for the Fountek fullranger? I think according to the description from boenicke it is not limited in hights, runs open to the end. It has only one high pass Filter? (10uf)?
