I thought I was making a long drive...Twin Cities? Thanks for the encouragement! I love a good project.
ADS-910's
- Thread starter GD70
- Start date
Merit badge? Do i need one? Sounds like it! I've had ....oh....30 or 40 pair of ADS...(2030 biamped with c-2000 includedĺ
Anyone tired of
the umbilical cord setup for the 910 xover? I have a permanent fix for it. Not selling, simply offering what I've learned.Secret sticky ADS dome coating?
Not so secret any more. This dome was COVERED thick with dust and hair, with grill marks all over it. Still perfecting the process, but a good start.
Am i wrong about this? Maybe! Maybe not. Sonic results? So far only used a non functional driver. I do coatings for a living, so think I'm in the right track. Feedback welcome and encouraged.
I've got the Braun 810, and the ADS 810. Happy to A/B them for you, if you have not done so yet.

That looks pretty good, but the true test will be how it sounds.
Your well deserved badge! 2030's bi-amped? Good God!
Why not? I'll be there and you don't see the Braun version very often.
Used a 7 channel Lexicon amp (at the time of this pic) 4 channels for the ADS, 1 for the center (Chapman C-3), and 2 for the rear, ( CM-7) Best setup i had thus far. Richard So reconed one woofer, and did some protection work on the crossovers. Picked these up in Bellingham for 400.00. Sold them to my buddy, got them back, then let them go again. The faint sound in the distance is my continued sobbing.
Indeed, the sound. Think someone with far more tech ability than i will need to step in on the sound test.
Here is my proposal: I supply 1 dust coated driver, and one clean driver to be tested by someone. I can run a freq on them and monitor with a mic, but prob might be a better way? A builder would be better than a listener like me. They measure the drivers, inspect the physical properties, and i re-coat the dusty devil. They measure again, and see where we stand. I searched on occasion through the years for a dusty dome repair, and found none. If there is one already, then my apologies. Through my years of the ADS/Braun Love affair, and as both a certified (NACE) coating inspector and paint contractor have been on the lookout for what would work, and what i FEEL is original, but perhaps made proprietary by a slight alteration of the compound. It has not happened over night, but has been enjoyable, so its ok if i am 100% incorrect. The dome looks the same, FEELS the same, but this one doesnt work. Next up, a functional driver, and someone other than me to test, rate, and record. Who am I? Been lurking in the background learning from many folks here, but dont post much. Im excited that i can POSSIBLY clean up my drivers...finally.
I shall not divulge in case im off base. Could be wrong, thats ok too. Im hopeful.
My first sets, i used to just re-solder the orig 6 way on the board, and use needle nose to rotate/twist the male side askew enough to bind when inserted. This "worked" but... wasnt satisfactory. I took a note from Jim at QRX restore and his pin method of the quad board. I use the shown 6 pin locking connector. 1. Remove female side from board. 2. Bare wires and insert all 6 into board, and bend them over 1/8 or 3/16" and solder directly to the traces. Then tie the wire bundle to the center screw on the woofer inductor so they dont pull on the board. Then cut the plug off the other side (input to speakers) and install the other plug (getting all 6 phased and lined up correctly). This plug is super tight, and locks. I "felt" that i heard a marked improvement in the entire speaker. The xover can still be unplugged as before, however has a longer lead, and CAN be layed up top to hook in, without un plugging it (protect the top). Having done this to 3 other sets over the last 5 years, it seems to work very well, and i have yet to observe a down side, though perhaps one does exist. I ordered 4 sets of these originally, and cant recall what they were called exactly.

Molex connectors, interesting. 
And eee-gads gents, I think many of us have been "out-gunned" by allhart's collection.

That sticky dome research deserves its own thread...lots of sticky domes out there!

WOW!!!!!! Curious why you let them go? Those are bucket list speakers!
That setup must have sounded unreal!
Indeed it did. With the Lexicon MC-12HDB preamp, and oppo bdp 105 I could play anything. Did mostly SACD and DVD-A on this setup. I also had a pair of Avalon Opus at this time, for 2 channel. The Avalon required some more expensive gear to run, due to how revealing they were. Had 30k into that particular setup, which I liked quite well, but did not "enjoy" as much as a simple receiver (Tandberg) and some 710's. (Or the like). I had gone stone CRAZY! Had VTL MB450 on the Avalon, ect...looking at my system began counting how much I had into it, and felt disgusted with myself. (Have 5000 records as well) People with whome I care for in need, the economy had been crap, but me oblivious to my surroundings while listening realized I diddnt LIKE me. Got a hair in my butt and sold it all. CHEAP. Regretted the 2030 sale..routinly. the did in fact sound killer in the outlined application. At that ohms each speaker got about 6-700 watts. Evenin 2 channel mode the Lexicon combo was quite impressive. However, the hair in but went away (plucked OUCH) AND today's system is less expensive, however, nothing to Sneez at (achoo)WOW!!!!!!

OPPO 105-D
Lexicon MC12HDB
Krell KAV 1500 (rebuult)
Chapman T-7 fronts (rebuilt)
Chapman C-3 center (new production)
Chapman T-7 rear.
Very enjoyable still yet.
ADS 1590/2 Rosewood for 2 Channel.
I do still have the C-2000 xover which isn't ideal for the 1590, could be used. I've heard of the mod that can be done, but know of no one capable. Richard So is a no-go. So I've biamped my ADS (and Klipsch Lascala) through an alternative method.
Well, I guess in time, my hair grew back...
Oh...the pain!
Molex! That WAS it. Thanks for the Total Recall. I should source them up again for the spare set of xovers on the shelf. (Missing one inductor)Molex connectors, interesting.

Quite a setup. I get sometimes needing a re-set, and you have a great system now. But yeah, if I had a set of 2030's, unless it was a life & death situation, I wouldn't let those rare beasts go.
