Re: DQ20 tweeter

 

I think that this might work:
Use the existing hole as a guide, lets say you want to open the hole by 1/8" in diameter.
Use a 1/2 router bit with a guide bearing on the tip that's 1/16" smaller than 1/2".
Route it out to a depth that leaves about 1/8" of the old hole at the bottom which will make the opening
1/8" bigger in diameter.? It is good practice to round over the bottom for smooth air flow and a rasp by
hand or drill type could be used to take that last 1/8" off and round it over.
I'm going to try this.

What a nice setup.?
Sadly few of us have access to such things.
If anyone knows of away to get this done at a reasoable price it would be great to hear from you.

Looking for the best midrange replacement for my DQ20i s and just wanted to note that the cutout is 4.25".
The mid is 5.25" but many modern types are too big for the 4.25" cutout.
The GR Research M130 requires 4.75" for example.

Thanks Pete! You're a good man! So my brother used his high end milling machine to properly mill out the spaces for the new midrange and tweeter. Also had to construct a new tube for the 6" midrange difference. Turned out great...the fit and finish. So here's what I ended up with.
-Hi-Vi L6-8R 6" mid
-ScanSpeak classic
D2008 852100
-Advent P001-31858
12" woofer
- All new Solens
Capacitors
They are just now getting stretched out and sounding fabulous! Obviously I'm not a purist! Lol I'm sure the DQ20 purists would be tripping because of the non originality! But I don't care...I care what my ears hear though. I wouldn't change a thing. Seriously.? I hope this message finds you well Pete. Let me know what you have going on.
You sound like someone who is always thinking and tinkering. Be well.
Sincerely,
Mick

My marked up schematic shows black/brown going to positive, and black/white going to negative.
Please let us know what mods you made and how they sound.

Pete, I'm getting ready to install those new mids we talked about on the DQ20's. Polarity question again...is the brown stripe the positive? Once again no markings on the mid connection. Thank you very much. Mick?
