    I replaced the tweeter. BOY does that make the old girl sing! This forum has been wonderful to bring a limp, frumpy organ back to her former glory. It's amazing to think this thing was built in 1974 ... it's older than me! It doesn't sound like the Casavant, Holtkamp, or German built Wech I played in college, but for a small town church, she holds her own. It is just so exciting to have made the organ come alive. Now, if I could get rid of the padding on the pews and carpet --- She's got a lot of music yet to give!

    The reason it's adjustable is because the setting depends on your environment and your personal taste. The answer to your question is to set it where it sounds best to you.

    I'm going to order me up one of these. We'll see how it goes.

    Anyone have opinions on where the adjustable high pot on the cross over should be set - 1/2 way, full???

    It is probably an 8 Ohm speaker, but you can measure the DC resistance with an Ohm-meter--if it is about 6 to 8 ohms, then its impedance is 8 ohms. This my recommendation for an 8 Ohm replacement. If the bad tweeter has an open coil (i.e., infinite resistance), measure the good one in the other cabinet. You should not need to replace both tweeters as Allen doesn't use stereo sound production so a slight imbalance won't be noticed. There probably will not be any imbalance, anyhow.

    Last question ... The other speaker/channel works fine. Knowing that a replacement speaker won't be exactly the same as the original, do I want to replace both so they match, or just follow the adage: If it ain't broke, don't fix it.

    Let me check my audio manual. I think it may have the ohms listed for the HC-10. I'll check tomorrow when I'm near the manual.

    The tweeter on the HC-10 looks like this .... will any old phenolic tweeter work? I see new ones are 4 or 8 Ohms. Would the original be stamped on the back? I didn't pull it out.

    The mid speaker is probably OK for now.

    Someone please correct me if I'm wrong, but isn't the tweeter on an HC-10 one of the ones with a phenolytic (Sp?) tweeter? Would the Peerless tweeter from the HC-12 be a drop-in replacement?

    started a topic Allen HC10 tweeter

    Allen HC10 tweeter

    I finally crawled to the speaker and found that tweeter is dead in an Allen HC10. There is plenty of voltage after the Hi adjustment on the crossover at the speaker terminal. Any suggestions for a replacement?

    On another related note, the Mid speaker has what I would say is varnish or glue over the entire cone??? The other channel speaker doesn't have this. It looks normal. I didn't take a picture of course.
Working...
