Great thread Gary!  I'll bet your AL-III's sound fantastic!  Thanks for posting and welcome to the Forum!

I agree this thread is an instant classic.  The photography was excellent - what camera and lens did you use?  Really good macro photography.  Impressive to see someone with the alls to tackle something like this.  Where did you source the cylinders used to separate components from? (see picture below)

Thanks!

Thank you~

Camera was just an older Sony digital camcorder, but it has the great ability to focus to @ 3 mm!

The cylinders are called AVRisers & are sold by Rick Ott from the CarverAudio forum.  Here's a link to his web site:'

Rabbits are common - especially in TN.  I am down on all TN guys this week as they failed to stomp SC this past weekend on the football field.

On the other hand, TNRabbit has 2 systems.  One he tinkers on at his place, and the other is on my deck.

I found symmetrical leading aircraft wing edges available in balsa wood for SUPER cheap (under $2 each) & ordered several in both 1/2" & 3/4" sizes to build my waveform guides to correct the notch resonance.   \/   I'll shape to fit & paint them black to match the ribbons:



I'll post pics when I get them done!

Someone asked for it, so here goes:

Before/After Review:

I guess I'd have to say the main difference is CLARITY. Cymbals are crystal-clear; the "edge" of instruments shows through--saxaphone, trumpet, etc. Stringed instruments& awesome voices sound so good on great recordings it could just make your cry. The closest I can call it is a "graininess" that was there before & now isn't. Before, if I played at moderately loud levels, it would sound better after about 30 minutes, but never as good as now. My guess is the caps & in-line passive crossover components were aged & in need of replacement. If I had all new passive crossovers, PERHAPS the difference between passive & active wouldn't be as great. Too late to tell for certain now~


On top of that, a lot more headroom is available from the amplifiers; I give a conservative estimate that roughly 40% of available power was wasted on the passive crossover components.

I can't think of a single thing that's suffered (other than simplicity) from the upgrade. I highly recommend it! Just don't skimp on active crossover components, & get the most for your dollar there.
