Crossover Porn

Seeing all these pictures are making my crossovers feel inadequate. There 6db on a two way, one cap and one inductor lol.

No kidding, my Norman 2 way crossovers look downright inadequate compared to some of these.

No matter, they sound great and they do have the 1970's tailight bulb that is glaringly lacking in those other XOs :)
 
These are the custom outboard crossovers that came with my Maggie MG IIIs (iPhone 6 for size reference).

And below are the onboard high frequency crossovers (yes, they're dusty).

My recapped AR90 boards. Mundorf caps on the series values, and Axon on the shunts.

Excellent application of the Axon and Mundorf caps. I'm building a pair of Nelson Pass JBL L300 crossovers using the exact same combination of caps - with one exception. I'm combining a Jantzen Superior Z-Cap with a Mundorf EVO Aluminum.Oil for the series midrange cap.

I'll post a photo when they are done.

Thanks! I look forward to seeing the pictures of your new crossovers. Plus, I'm definitely curious on how the EVO Oil's and Superior-Z's will mix? I've used some ClarityCap ESA's since the Mundorf's, on another AR recap, and I think they would combine well with the Mundorf caps too. Warm and open, hopefully?

Westlake Audio TM-3VF. Nearly all caps will be hand matched and measured Solen. Westlake's networks are hand built a pair at a time.

Now THAT's a crossover. :) I like how the caps and inductors are color coordinated. Obviously, it makes no difference to the sound, but is a nice touch. The ratio of caps to inductors & resistors would indicate that they are doing more massaging to the frequency response than the one in the original post.
Imagine the look on some AK member's face 50 years from now they open the speakers up to do a recap. :eek2:
 
I built these for my JBLs. All Solen Fast Caps with Theta by-pass caps, Mills resistors, Erse coils, heavy wire, and silver solder.

This subject brings back memories of repairing crossovers and replacing drivers that had been over powered. Crossovers of the 70's did more than just divide frequencies. They corrected for speaker impedance curves, frequency response and changes in drivers to get a matched set ofxrt22xover.jpg stereo speakers. Guess which speaker? They were from the 70's and used lots of tweeters and X was part of the speaker model name. X__-__
 
These are the crossovers I'm making for my new speakers that use 18" and 10" JBLs and Heil AMT. The lugs are spaced for double bananas. Because I made the 8 mH low frequency inductor from three 2 mH values, I have various "taps" available. The 11-position "Bass" switch allows me to change the crossover frequency and contour the bass by using the full length of the inductor (160 Hz) and if desired, bringing in the other taps via resistor for more presence. Even though the 10" goes below 160 Hz flat in the nearfield, it's a whole 'nother story across the room and letting the 18" play higher than 160 Hz, at reduced levels, makes for a fuller sound. I don't know why these letters cut through after they etched in but will figure it out.
