Ok, I don't mean to be redundant about my love affair with Claritycaps....but....I had replaced all of the solens in a 3 way Dynaudio system in just the mid and tweeter sections. It was very spendy, about $200 worth of SA and PX series. The system consists of a 24W100 10" woofer, 17WLQ Esotec 7" mid, and a Esotec D260 tweeter, designed on LEAP about 10 years ago(crossovers acoustic at 250hz and 2500hz)....for the JBL nuts, I do have a 2245H and BX63A for the lowest end (modified with Mundorf silver/oils, Auricaps, etc).
Anyway, I had a 180uf cap in the 250hz low pass to the woofer. It was a parallel cap between two Erse inductors. Very large, for sure, and I had 80uf and 100uf solens in there. So, I bit the bullet, and replaced them with 6 each of the 30uf PX series claritycaps....damn, what an ear opener. Complete perfect blend now with the rest of the system. The bass (and guitar, vocals, etc, etc) is transparent, tight, punchy, natural....right. Spent over $125.00 just on the low end caps. It was worth every penny. Amazing difference in every way. I am aware of those who would just biamp, and forget it....but nothing is more focused or as good a blend as a LEAP designed passive....and even the best active crossovers (I have Ashly's in my live rig) have IC's, mylar caps, high and low filters, another power supply, etc, etc....which I feel add more coloration and haze than a good passive setup. Especially if the dcr of your coils is taken in to account in your box design and tuning.
If anybody wants to know, yes, it is worth it to replace ALL of the caps in a 3 way system with similar caps for a good blend, and nothing is more affordable at anywhere near the performance of the claritycap. Go humblehomemadehifi.com and check out a neat website with info, and go to e-speakers.com for pricing and ordering. Hope this all helps anyone that is contemplating what I have done. The SA series is more transparent, but the PX series is damn close, and less money for the really big values. And, yes, these caps are HUGE.
The photo is the mid and tweeter sections only, but you can see the relative size of these caps. My camera is a dinosaur, as you can see. Since the signal goes through dozens of feet of inductor wire, including a tiny voicecoil wire, I don't use huge monster wire as I once did for connecting components and drivers. 16 or 18 guage solid core does it just fine (bastardized from some audioquest speaker cable), and is easier to work with and do a neat job. 12 guage wire for a 3" or 6" length doesn't seem to be worth the audible effort....for me, anyway.
All of my systems have claritycaps now. 4406's, 4301B's, 4208's, and 7" Dynadio 2 way surround speakers as well. These caps transformed all of these already decent systems by an amazing margin.
I might also mention that I finally got rid of all of the cheap wire wound resistors, as well. The mills resistors I got from parts express are incredible in comparison. Pure, smooth, with way less hash and grit. At $3.85 each, it is a cheap improvement.
