Found this so makes sense. I think using 22ohm in place of 22.5 will be fine for T2 and 3. -
That's interesting but what you'd want to see is sPL in dB vs frequency for all 4 tweeters separately and their summation. Where did you get that....I think I remember seeing it somewhere but don't remember where.George / NJ

Was there any explanation of the key in that? I don't understand what V(R6:1), V(R7:1), etc. signify. Obviously it is Voltage but are they locations on the PCB where the measurement is taken? Doesn't compute.George / NJ

It’s from an old conversation I ran across. F1nut may know more.

Finished the rebuild. Came out great. Really opened up the soundstage. Sound better than ever.

Who did you buy the 22.5 path audio resistors from?

Special order, how long of a wait? -
Took about 2 months.

I had given up and was going to use 22’s and then they finally showed up. Parts Conn is pretty bad with communication. I think I got them for free actually.

I have 4 22’s if anyone wants em.

Anyone notice whats wrong with my pics???

Where do you ground the Path resistors?Don't take experimental gene therapies from known eugenicists. -
to tweeter ground- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

To tweeter neg tab/gnd.

But is it the correct Path, or Path of least resistance?Don't take experimental gene therapies from known eugenicists.

Perhaps those could be run through the window to a dedicated grounding rod pounded into the ground.George / NJ

Overall, kinda suspicious of the mechanical stability of that top panel. Seems to be attached in six places, but to the plastic edges of the three big inductor bobbins. I suspect it'll sag over time when mounted in the speaker cabinet due to gravity and vibration.

There's a hole in the upper plexiglass board that is missing a screw and standoff.George / NJ

I even LOOKED and didn't see that. Maybe my subconscious was trying to tell me it didn't have proper support.Steel self-drilling/self-stripping screws used to secure the ends (and maybe steel screws for the four THREE center standoffs) of the top panel to the inductors?

I only found it cause I was trying to figure out what you were talking about. So I owe it all to you ha ha. And my mother and father and...........long story.George / NJ

Looks like you need to swap the big Solen caps with the big Clarity Caps.Polk SDA SRS 2A

You are correct.

I'm in the middle of reworking my 1987 vintage SRS crossovers, REALLY like the way you stacked the caps on plexiglass. Now I have to redo my less than stellar effort and mimic your setup!
Did you use 3/8 plexi?Polk SDA SRS 2A

Thanks. No just 1/4 is fine. Tricky to cut and drill.
