Well, I dug through my parts bin, and it looks like I'm going to be ordering most of the parts, lol.

Madisound doesn't seem to have the 0.15uf caps (I usually use Solen) so I'm going to have to snag Auricap from parts express.

Has anyone used them before and are they decent, within good tolerances and such?

The 0.15uF could be find if you have a local electronic dealer ?

if this one ? too expensive
Auricap 0.15uF 400V Capacitor

This one can do the job but ten pieces...
0.15uF 200V Polyester Film Capacitor

10 probably wouldn't be bad either, I plan (eventually) to re-do my center channel and all 4 surround speakers with the same parts at some point in time.

I priced them out and it looks like it's going to be around 80 usd for each crossover, which isn't too bad, but most of it is the coils.

Damn you copper prices!

Jerome, could you check this shopping list and make sure I read all your values correctly?


Coils: 2.2mh, 1.0mh, 0.22mh.
Caps: 10uf, 2.2uf, 0.15uf.
Resistors: 3.3ohm, 10ohm, 6.8ohm.

Just want to make sure I didn't move any decimals where they shouldn't be! Also, it appears that Solen has the 0.15 caps for $1.83, much cheaper!

It's ok for me
Choose a good film cap 10uF and a low resistance for the 2.2mH (0.1..0.3 ohms). The 1mH and 0.22mH don't need low resistance.

Merci!

I had planned on getting pretty much all Solen parts, except for the resistors. I'm pretty attached to their stuff, along with Goertz.

The Solen 2.25 claims 0.33 dcr. Should do pretty well!

Wow. I quickly twisted together some extra components I had laying around in this basic design and I have to say, what an improvement! Much more relaxed, less edge / harshness and great dynamics.

I can't wait to hear what they sound like once I order all the correct parts with the right values.

I finished the new crossover with proper values last night. I'm still in the process of listening to a variety of material, but so far, I'm very happy. They are much more relaxed and less fatiguing than they used to be now that the M6A peaks are under control and the tweeter FS is damped.

I just wanted to say thanks one more time for giving me a head start on learning Speaker Workshop and for helping me with a starting design. Next step, learn how to implement BSC!

Hi,

If you have copied the bass section of the ZX Spectrum c/o, the
value of L1 should tell you that you have already implemented BSC.

rgds, sreten.
