Crites crossovers, rebuild or new for Forte IIs?

    I had Forte IIs for ten years, what seems like a long time ago now. Rebuilt my own crossovers with some paper in oil caps, purchased a bunch of upgraded resisters to dial in close tolerances. Added vibration damping to the backs of the horns.
    After all that, it wasn't much if any different than stock. Probably because I put in upgraded replacement parts with stock values.

    My advice, buy the ALKs. You can always put updated parts in the stock crossovers to refresh them which would be more similar to the Crites and stock versions.

    Believe me, you want the better sound than the factory Forte II's.

    As Al form ALK indicated, the decision to upgrade to titanium diaphragms is up to you.

    I don't particularly care for them myself. One of my pairs of A7's has them and I don't care for them. They sound metallic to me.

    My main A7's with the ALK crossover's, don't have metal diaphragms and I think they sound more natural.

    I would do the ALK crossover upgrade first and then decide from there.

    I would definitely want you to hear the Fortes II with the upgraded crossovers first, before you do anything else.

    I agree, if you go this route, do these, listen for a while and decide if further upgrades are needed and if you do the diaphragms you will then know the changes you are hearing due to the diaphragms. I built a pair of Super Heresy's (google them if interested, Claude on Klipch forums) and used ALK crossover. Being these were built from scratch I don't have a frame of reference to compare but I think they are quality built and sound good, but nothing to compare against. Good luck!!

    I have Forte 1's. Did the Crites full crossovers last Saturday. Made a already great sounding speaker even more enjoyable. Took all of an hour to swap out. YMMV

    As I have already commented, it is not only Klipsch, but Altec Lansing. They both know how to manufacture outstanding speakers, but neither of them knew all that much when it came to crossover technology. Besides that, capacitor technology, with regard to audio has vastly improved over the years.

    This is on of a pair of A7's that another individual had customized. He spend a lot of money cutting 8" off the bottom of the original cabinets and enclosing them in an outer cabinet, which he had veneered in what appears to be a black walnut real wood veneer.

    The Eminance Kappa Pro bass drivers that are in my main pair were $175/ea. and the bass drivers he used in these cabinets are from Europe and cost $350/ea. by themselves.


    The drivers for the HF horns that I use are the 908 series, which have the Altec Symbiotic diaphragms, while this pair has their 9+02 series, which are aluminum. I don't particularly care for their "metallic" sound. I don't particularly care for most metal tweeters.

    The 908 series drives handle twice the power of the 902 series, which are supposed to be the better sounding drivers. I don't agree.


    These also have their original Altec Frequency Dividing Networks (which is what Altec calls their crossovers). The previous owner spent some money having them recapped, I don't know with what, but I still don't care for them. They need to be replaced with ALK crossovers and the diaphragms need to be replaced with the Symbiotic variety.


    These cabinets have custom made, removable grill cloths, so they look like large monoliths, with the grills installed.

    The grills are photographed in front of a corrugated aluminum warehouse door.


    Just because you use expensive components, is no guarantee alone, that you are going to end up with a superior sound.

    These custom speakers are still going to require some time, money and effort in order for them to sound their best.
