Putting the speaker tweaking cart before the electronics horse.

Howdy Al!

I just made X-overs for my Chorus II's

using the original schematic.

Used Solen air cores, and caps.

Still playing with the mid, though.

I had a 5.6uF Solen bypassed with two Harmony 0.22uF.

(They didn't have a higher value.)

Sounded pretty good.

I had some extra money, so I picked up a pair

of Crescendo 6.0uF caps.

(These are double the size of a Solen 6.2uF.)

Them Hovlands are spendy, I'm sorry.

Sounds a little better.

I ordered some cheap Madisound Carli polyesters

on a whim.

I tried a lower value, 15uF polyester, and it

seemed to really smooth out the mid-horn, but

it was a little too low.

So I'll try a 6.0 Carli, to hear the difference.

I'll probably end up sticking with the Crescendos.

The mid circuit still uses the autoformer, of course.

The X-over is the same as the schematic, except

3.6mH (Solid 12awg) for the woofer, instead of 3.5mH, and 1.8mH (14awg litz) for the midhorn, instead of 1.75mH.

Couldn't afford to have 50 custom wound.

But the resistance for the 3.6mH was .55 ohms.

The stock 3.5mH was .59 ohms.

Real close.

The only resistors of quality without stacking,

was the Mills 20 ohm 12 watt.

Expensive, but probably worth it.

Boy, the high end came to life after this upgrade.

The bass is tighter and clean, though I may have

lost some bass, it's probably me being used to

boomy speakers over the years, so I'm dismissing

it as that.

I have a pair of subs for the bottom end anyway.

They seem to be getting more bass as time goes on.

(The crossover's only have about 10hrs on them.)

I'm in the Solid State realm, with a Yamaha

MX-1 amp, and CX-1 pre.

Thanks Al, for having your site, with those nice

pictures of your crossovers.

I spent one night looking at the Cornwall X-over

photo and the graphic.

With this, I could ponder out a layout for the

Chorus II, the solder posts, terminals, etc...

It helped out a helluva lot.

(Plus you helped me out on a couple of questions

on the BB.)

You are doing the Klipsch heritage owner's

a great service, IMO.

Hopefully these guys will keep you busy this coming year!

THANX! And a Happy New Year!

PS, I think Kelly needs to do some DB testing.
