My son's neighbor just gave me a pair of these. Physically they are in excellent condition, but my walk from house to car and back... twice... justifies a wait before I can hear them. I know they were stored on their sides for a long time, not being used, but the environment was pretty ideal. I run all my audio (such as your review) through a Realistic STA-95 and Optimus 1s. I can listen to anything all day with no fatigue and I highly enjoy what I'm hearing the whole time. I'm eager to hear the comparison. Hopefully tomorrow :) Thanks for such a great video.

I used to drool over these in the Radio Shack catalog. I never did get a set. I eventually ended up with a pair of Fisher "Studio Standard" with 15s.

@@vintageaudioreview no stock electrolytics will sound as good as polyester or metallized poly low ESR caps. I’ve modded everything from Kef to Klipsch and there is not one example of electrolytics sounding as good. Electrolytics dry up and degrade in as little as 3-5 years, let alone 39 years. The midrange and treble clean up considerably and don’t saturate as easily with better caps.

@@scottlowell493 My experience with testing caps (value,ESR and leakage with the appropriate voltage applied) has shown that many caps that are >40yrs old are still fine. I read a paper in the last 6month that showed there really was no difference between the expensive "audiophile" caps and others. If your experience tells you otherwise, then you are going to disagree but that is what the hobby is about, I suppose.

@@vintageaudioreview we totally disagree. Too many variances is electrolytics. Poor quality , Memory, smearing the sound. They sound duller and more closed in. Square waves look like sawtooth. All of the people that have heard the mods vs original said the same thing to me, without me telling them anything. They are not exotic audiophile caps. They are a couple bucks like Dayton 5% or similar. If YOU can’t hear a difference, you have the problem. Hearing or listening skills, or perhaps poor electronics feeding them like murky and rolled off vintage receivers.

@@scottlowell493 At least you are using reasonable priced caps. My listening skills are quite good, I think, and completed Harmon's "How to Listen" training. As I have tested all of my gear, no problems there. I doubt most folks have the audio memory to be able to tell the differences you are suggesting. I am not talking about a capacitor that has changed value by a very large amount over their rated spec. If you had a pair of speakers and measured their freq responses/impedances and they were very close, and then did an a/b test and were convinced they sounded pretty much the same, and modified one of them by just replacing the caps with ones that were the same value but some other material, and then remeasured them, would there be a difference ? Will have to talk with an engineering friend who builds speakers and designs crossovers to get his take on this- I have never had to replace any crossover components- might make for an interesting video.

Perfecto 👍

I really enjoy my Mach 2's. I have four hooked to my onkyo m508 system. I had the woofers and midrange refoamed. Have not done anything with the crossovers. When listening to CD's with the onkyo DX 7500 the system sounds really good to me.

Great video. I subscribed. I almost got a very nice pair of Mach-1 for $190 today but someone could pick them up before me. I have the Klipsch kg4 and like horns now, even though that is a mid-driver horn. I recently got a Rogue Atlas power amp (2005) for $400 and a pair of Sennheiser Momentum 3 wireless headphones (like new) and the kg4 are so much smoother than on my Onkyo SS AVR 6.1 amp. Thanks!

I have no doubt that replacing capacitors and/or inductors in a crossover network can make a big difference in the sound of speakers. We have reached an impasse, it appears.
