CX100's Resto-Mod
in BeoVox · Jul 7, 2024 17:31Finally got a weekend day to reassemble the new covers. Had to grind down the factory ABS crossover mounts to clear the alloy crossbraces. I like the nickel plated binding posts with the patina. Added 4×4×5/8" open cell …
CX100's Resto-Mod
in BeoVox · Jun 19, 2024 12:25Finalized with fly-cut cross-hatch machining and omitted the thin sheet metal bracket mounts as they'll be attached and sealed with polyurethane rubber adhesive. This will mitigate any resonance at the highest volumes...…

CX100's Resto-Mod
in BeoVox · Mar 13, 2024 01:38The other midrange coil was fried, so I unwound a 25.5mm ID 6.5ohm coil down to 5.2ohm to match the other midrange driver. Cut to 0.950″ total length with 0.44″ coil length to match as well. Glued in and set with shims l…

CX100's Resto-Mod
in BeoVox · Mar 11, 2024 19:10If the driver with the hole in it is NOT the midrange, then B&0 factory installed both my CX100's backwards and got the wiring WRONG.... I'm only going by ears for the sound improvement. As I stated in another thread tha…
CX100's Resto-Mod
in BeoVox · Mar 11, 2024 13:42Again, I removed more mass from the moving dust cap than what was added from the thin layer of dried latex (for cone damping). The speed increase of the lighter moving cone translates to better transients. Here's what B&…
CX100's Resto-Mod
in BeoVox · Mar 2, 2024 01:08After new surround is glued and dried to basket frame flange, I use just a drop off black latex paint to dampen the cones and dust cap. It dries to a miniscule added weight and rejuvenates the dried paper cones as well. …

in BeoVox · Mar 1, 2024 21:35I foamed (1/8" thick open-cell) the inner frames and applied 2 layers of thick polyurethane adhesive to the outer frame baskets first thing after removing old rotten foam from cones with mineral spirits. I protected the …

B&O Inspired Amplifier
in General Discussion & Questions · Feb 21, 2024 17:25I've owned quite a few classic Beovox and I have to say these are the best imaging and midrange-detailed for their size. I have another set that I will do the exact same modifications to. I have built custom baffles out …
