Will I notice improvement with crossover mods?

Mitch just let me know when you get tired of them. I will gladly take them off your hands.LOL

I am sure your wife will thank me!

"anyone know of source for cross-x mod for aerial 10-t.thanks,bill."

Bill, I just bought an Aerial CC3B. I'm an incorrigible tweak and e-mailed Aerial for info in the crossover.

If the 10-T's crossover is as complex as the CC3B's, it's complex indeed. All 4 filters are 3rd order and there's at least one tuning circuit in the midrange. Aerial told me they've been using the Axon polypropylenes forever in their crossovers, and they're not bad-sounding at all. My crossover has 6 Axons on it, 3 33s, a 12, a 4.7, and a 3uF. The 3 and 4.7 are series caps for the tweeter, and I've replaced them with auricaps. I bypassed the 2 33uF midrange-series caps (with good caps I already had) but probably I won't replace them. Mine is full of Bennic-brand resistors and as soon as I'm satisfied about identifying them, I'll be replacing some of them.

I THINK my CC3B sounds a little cleaner, but my aural memory is very short--I have trouble identifying some differences in immediate A/B comparisons.

Are your 10-Ts early or late? I understand the 10Ts were upgraded seriously during their lifetime.

I'm glad to hear that you're still "foaming at the mouth" over your "new" speakers Mitch. Given that you started off with what most would consider "better than most" passive parts in your speaker, can you even begin to fathom how some older but very well designed speakers using lower grade wiring, electrolytic caps, scrawny inductors, etc... would benefit from such an approach? This is why i've encouraged others to find good basic designs and build upon what was already there, much like what you did. With designs that are even older than yours, the results can be even more drastic and staggering in terms of improvements. Sean

Well, I am not one to usually say "I told you so", but in this case, that tweeter NEEDED to go. Personally, I am of the opinion that the tweeter change should have happened prior to the crossover mods, but Sean will probably disagree. Fair enough...

As the Hales have a really good cabinet and woofer, with your crossover mods and tweeter upgrade, you now have a speaker that competes on a VERY high level, at a cost that would NEVER allow you to play in that ballpark otherwise.

All I can say to everyone is that if you have a pair of 7 - 15 year old speakers with this kind of potential and do not follow in Mitch's footsteps but "upgrade" instead, you are going to cost yourself A LOT more money and get LESS performance in the end.

sean...I did outfit my speakers with AWG10 coils and fancy capacitors and I do think that performance improved, although I can't say that the slight change I made to the component values (crossover frequency) might not be the reason.

However, do you have any technical explanation regarding WHY a coil with 0.15 ohm DCR should sound different from one with DCR 0.65, apart from slightly less attenuation (so that the volume control needs to be cranked up a bit)? It's been noted that after passing through the coil, the signal traverses some hundred feet of very fine wire called a voice coil (or in my case fine wire glued to a mylar diaphram). Why does the DCR of the coil matter?
