As I mentioned in my introductory post, I'm the new owner of a pair
of DQ-10s. However, the 2" midrange dome and 3/4" dome tweeter on
mine are bad.
For the midrange, the tinsel wire has been burnt up or broken inside
its protective resin right where it enters the cloth dome. The voice
coil is in good condition with no evidence of being overheated and
the like loosening of wires, continuity there also checks fine. So,
it must have been a mechanical breakage. In the past, I have
repaired similar breaks in similar drivers (the 2" dome midranges of
a pair of Infinity Quantum 2s), however the proximity of the break
to the dome makes such a repair too difficult to undertake. And so,
I am in need of a company that might be able to affect a repair of
this driver or a source for good, but used equivalents. I am aware
of Regnar, but so too am I that their prices are above and beyond my
range.
As to the tweeter, the aluminum tinsel leads have corroded from
exposure resulting in one breaking just as it passes beneath the
magnet cover. Unlike the midrange, this driver appears to be glued
together rather than screwed and so I cannot take it apart for
repairs. Nevermind that my success at resoldering aluminum VC wires
even with the appropriate solder has been minuscule. So, I need one
of these as well.
Another issue I discovered while tracking down the above problems is
that the woofers, while largely the original Advent woofers with the
masonite ring, have been reconed in the very recent past. The foams
and cones are spotless, but rather than the dark, almost purplish
cone with annulae, I find that mine have light grey and very plain
cones. The foam surrounds, however, were reglued appropriately.
Anyone know how I might identify whether the woofers were reconed
appropriately with the correct cone mass and VC replacements? There
is a number printed on the back of the cone that I do not remember
nor wrote down, but that I can retrieve if it might point to the
answer. If need be, I do have a pair of Advent/1s on loan to some
friends that I might retrieve and sacrifice for a woofer transplant.
The drivers in these speakers I believe are the same as found in the
New Large Advent and thus are the same that Simply Speakers sells as
replacements for the DQ-10.
While I have mine apart and am working on them, I do plan on
eventually recapping the crossover as per the schematic in the files
section. I'll likely also affect the mirror imaging project shortly
after I can locate the needed replacement drivers. So, I might as
well implement any modifications at the same time. Does anybody have
experience with various modifications or suggestions for what I
might do to improve these speakers? Since half my midranges and
tweeters are shot, perhaps there are better options available that I
should install rather than direct replacements? Any and all
information would be greatly appreciated.
Thank you for your time.
