Likewise. I got a lot more definition in Frank Sinatra's voice, and the horns and drums had more punch. I removed my A55G/2s for the time being, but I plan to use them again with the next crossover, probably the ALK CSW-450.

I stand corrected. MY ears don't lie. I'm always right in that department.

You may not need an adjustment at all. You'll know when you hear it. Ears don't lie.

@Crankysoldermeister, so what are the acoustic differences between the CSW-450 and your design? I know you're biased toward your design, and that's fine by me.

I haven't figured out what that chart means. I'll youtube it. However, my K-400s are wrapped in Kilmat, which definitely adds to their clarity. That may be a consideration with the boost in volume and clarity, which is definitely more pronounced with the A55G/2s. More experiments to follow.

I've added Kilmat to my Heresy and Chorus II mid horns. The audio improvement was substantial. For my Heresys, the Kilmat improved the bass and high mids simultaneously. For my Chorus IIs, the Kilmat completely got rid of a honking hollow sound that was very distracting. Kilmat may not be as dramatic as a better horn, but it is a substantial improvement.

Well... the tweeter and woofer music was a bit more recessed. The A55G/2 music was very forward. A lot like the loud kid in the class.

The volume levels and audio quality from all three drivers were out of sync. Based on my Heresy experiments, I think the ALK CSW-450 plus my new tweeters and mid drivers would give me the flexibility I need for experimentation.

Same here. I got more space and detail with my A55G/2s. However, the overall sound for my La Scalas was not balanced with my new crossover caps from JEM Performance. So I got new diaphragms for my K55Vs and reinstalled them. The sound is very balanced now. I'm still waiting on another ALK crossover, at which time I can experiment with driver levels for the A55G/2s.

Hadn't thought of an NUC. I'm using a Schiit Audio Modi Multibit DAC for streaming from my Sony tv. I really love the PrimaLuna EVO 100 tube DAC design. That's my next DAC move.

For what it's worth, I went with the Furutech copper connectors, as they were the only copper connectors I could find. Carry on.

Thanks for the input. I assumed ALK's crossovers are more in line with modern Klipsch crossovers, and Dean G's crossovers are more in line with the originals on steroids. I really should get Dean G's crossover and compare it to my audio memory of the ALKs in my Heresy pair, or just get both.

Definitely.

I found Al's design philosophy regarding the AA crossover, as well as a schematic on his website for his CSW or universal design. The CSW-450, for a little more cash, has a woofer filter at 450 Hz, similar to the AL5. I am making a meager/fun attempt at imitating the AL5. The CSW was wonderful with my Heresy I pair, especially with SMAHL tweeters. I'm expecting more of the same from the CSW-450s for my La Scalas. http://www.alkeng.com/bad_AA.html

Yes. Inquiring minds want to know.

Deang designs crossovers for the La Scala et al.

Validating my findings is unimportant in this exercise. Audio quality is the only measurement I'm using. Ears. Speaking of audio quality, I know you've listened to the ALK CSW-450. What is the sonic difference between the CSW-450 and your crossover, according to your audio standards/ears?

Never thought I would. I'm waiting on a high quality crossover. I also have my new tweeters and mid drivers waiting in the wings. Didn't think the wires and connectors would be an issue, but they were. Fixed it.

I'm used to hearing live drums, guitars, vocalists, etc. The goal is to get my kit to sound like band practice. Composing music is goofy too.

I was thinking the same. What I'll do is get 10AWG copper connectors. Wrapping 10AWG around those little screws on the crossover isn't my best option.

Excellent editorial skills.

Still there. I'm wondering if this listing is real.

Good to know. Bare wire will be my next experiment.

These connectors gave an immediate upgrade to the sound. Much better than my home made adapters. Maybe I'll put copper connectors on all of my crossover terminals.
