    Should I get new Xovers??

    in Technical/Restorations

    OK, so what about an "A" network. Looks like a 1st order slope on the tweeter with no back to back zeners for protection. It's less than $200. Since I don't use high power amps with my Khorns (actually part of a 5.1 system with and integrated Onkyo receiver, so no RCA's between signal and power to come loose) I will never accidentally sledgehammer the tweeters with a disconnect.

    What do y'all think? Anyone tried an A network vs. the AA?

    Yes, you should be worried about the caps in the 77 xovers.

    Buy these crossovers, or have the same guy refurb your crossovers, can't go wrong.

    He supports diy refurbs, too.

    Any of the options would work fine. You will be amazed at the improvement in sound from having fresh caps in your crossovers.

    I was always suspicious of the aging potential of capacitors in the Xover in the AA's vs. all the Poly caps all the "golden ear" tweak were touting as upgrades to any old tube or x-over stuff (electrolytics being the best upgrade candidates, I guess). I'm not trying to second guess PWK's engineering or the factory people's ability to verify my K horns were fine 29 years ago. However, chokes certainly don't wear out, my horns have never seen more than about 100 watt peaks (mostly alcohol/good caompany induced) and have cruised along at 1/4 watt power levels most of their life, so the woofer's suspensions have not been strained, no equalizers have ever boosted the low end, phenolic diaphragms are rugged and have probably never seen more than a few milliwats in the treble sections.

    So, it's strictly an age, not abuse, issue. Will I REALLY hear a difference if I just replace the Caps (which is all I want to do anyhow) or is it just a peace of mind thing.

    Saw a pair of AA replacments with what looks like Poly capacitors for less than $300 on Ebay.....made in Arkansas, by, I presume a former Klipsch employee.

    My Horns and single LaScala (formerly 3 channel with passive mono bridge from PWK himself) now part of a hybrid 5.1/stereo setup.

    Anyway my AA networks are 1977, so should I be worried about the Capacitors???
