I’m thinking about getting rid of one pair, and keeping one, “for a rainy day”, and need to decide whether it’s the ‘s, or the ‘s, that will hit the bricks I even used them crossed at 1st order with no problems in home use with Altec drivers but JBL s used on the crossed at hz 1st order “clacked”. However, I recently purchased a single horn for a center channel in a 7. It was all the rage — a decade or two ago. After mounting them and driving with Altec g’s, I couldn’t hear any ringing.

Back when I used the cabinets, and horns, for home stereo, I hofn amazed at how “live” my music seemed! What are you looking for in a woofer? Thanks, very much, for any thoughts, or comments on the performance of these two horns.

I realize, now, that this, too, was probably an effort to dampen any ringing coming from the horns.

Of course they are coated to begin with and don’t resonate. If I were to go to one pair I’d keep the s as they are more versatile and look cooler. A parallel cap, coil, and resistor in series with the driver will do.

FWIW, when I built my ‘s into sled deployment I was aware of folks describing a “ringing” with this aluminum horn. Clean the surface, heat it with a hair dryer, and stick it on. I just looked the stuff up and can’t find it but there are many companies selling the stuff.

I usually find all sorts of awesome speaker parts that I forget that I had. I use a sticky backed damping material sold at car audio install stores.

IMO for home use there’s no better sounding 1″ horns than the and My horns were treated with 1″ flexable foam rubber sheets. Much appreciated, and God Bless! Most folks pay special attention to the exit flanges of the horn. Sep 28, Likes Received: That’s very interesting stuff, and I appreciate your having sent it along to me.
