DQ-10 System Restore

[bored184]

If you followed my last thread, LINK HERE, some of you know I have had some issues with my DQ-10s. The time has come to tackle this project.

Stands
I started with the stands because the DQ-10 speakers are currently working. In the living room the carpet is pretty plush and when they are on their stands they sit unevenly and could of easily been knocked over. I had my father cut four 2in x 24in x .25in steel plates. I also ordered 2 sets of Dayton audio spikes. Come spring they will get painted black.
The final result.


DQ-1Woofer
The woofer had excessive voice coil drag and had to be shipped off to Miller Sound for repair. He did an excellent job with a quick turnaround. I will post photos if anybody wants more details on the repair.

MX-1 Crossover
In my last thread we know the external cross over has some issues. Upon closer inspection I think I found one of them. The NPE cap in the below photo looks bulged, I apologize if its hard to see in the photo.


Parts List

4x 150uf cap
1x 80uf BP cap
1x 160 NPE cap
2x 15ohm 25Watt resistor

New Parts

I had to go with all NPE caps because of size and cost. Four 150uf poly caps would of cost me near 200 bucks from Erse.


P.S. I apologize for any grammar mistakes. I did this with a 1 and 3 year old on my lap. More to come during their nap time.

Nice to see the crossover getting attention. We have all seen and posted speaker upgrade-rebuilds and such but the crossovers haven't been shown much.

Nice stands. Another interesting approach to the base of the stand. Looks good and matches the speakers.

New parts in, the resistors checked out just fine so I left them in. In this photo the transformer was removed, it made getting to the resistors a little easier.


Using the setup below I had a friend get me some ohm readings on his.


Friends Readings (stock and known to be working):
Left:
Max - 1 ohm
Medium - 31.5 ohm
Min - 16.1 ohm

Right:
Max - 4 ohm
Medium - 3.9 ohm
Min - 3.9 ohm

My readings (recapped):
Left:
Min - 15 ohms
Medium - 30 ohm
Max - my meter climes, must be charging a cap. Sitting at 50,000 ohms but still climbing.

Right:
All - 3.5ohms


I plan on checking the caps with my Eico 950B after Christmas to see how much they have drifted over the years.

Thanks! I'm still thinking about running a piece of wood in the front to match the wood on the side. Don't know if it improves the sound quality but it sure helped with stability which is what I was shooting for.

Take a look at the speakers and the active crossover, no front chunk of walnut. If you are happy with the look without the brown wood across the front, you are more matched to the family. Put the wood on the sides of the MX-1.
