I've been doing the capacitor-go-round in my speaker crossovers for last several years and have found that polypropylene caps consistently sound more open and dynamic than polyester caps.
Here is a list of MKP caps I like:
Mundorf Silver in Oil highest price
Jantzen Supreme high price
Sonicaps medium price
Audyn low price
All in my humble opinion of course.
I also use and recommend these caps for interstage coupling in amps and preamps, not just speaker crossovers BTW.
I use Marchand tube and a modified rane
You hear the difference between a great amp or amazing amp
Do you cascade over to the Rane ?
Hi I use 2 different systems,the one with the Marchand
The input is via a tvc to the Marchand then split into 5 mono blocks and 2 stereo amps,I use a 4 way all horn system ,yes the sub plate amp and bass horn amp is cascaded
For the rane direct input from tube preamp ,the bass output is cascaded into a stereo amp and plate sub amp,the time delay really helps with dialing of horns,
As brooks shield said, nothing comes between my amps and voice coils.
Me too, I highly recommend Marchand active crossovers.
Remember, it's all about the music.
I also totally agree with both of you. The best cap in the signal path between the power amp and the driver is no cap at all. I started using various active electronic crossovers in 1982. The first was a pro model from Crown which sounded only fair by today's standards but much better than passive crossovers. I used numerous other active crossovers up until about 2004 or 2005 when I bought an early model DSP engine from DEQX. I have a much better DSP now, and I feel that is the best route to a musical sound that best pleases me.
Are you finding a difference in the low and high portions of the network?
Yes, I find that better caps are more noticeable for tweeters and mids than for bass response. You can get by with lesser quality caps for big bass values.
Mids and tweets have a cap in series with the driver to protect them from low frequencies, on the woofer the cap is in parallel thus not in the signal path.
Only those of you that have them are.
So you're saying you have no coupling caps in your amp, preamp, DAC, player or speakers?
I don't have any caps in my speakers. No crossovers at all.
Everywhere else you mentioned in your reply, yes, I have caps. I was just having a bit of fun with your use of the phrase "Were [sic] all listening through our caps" with regard to speakers.
Any added external electronic crossover will have caps in the active audio circuit ( to create the roll-off ), and more caps in the power supply to filter the supply voltages.
It becomes a question of
(a) using a passive crossover, at speaker level or
(b) having a whole other gain stage ( called an active crossover)
with extra cabling, extra RCA jack connections ( in and out ) and less than perfect electronics, repeated " one more time" in the added external active crossover's line stage.
The user gets to " pick their poison ", so to speak.
I prefer as simple as possible, and HIGH efficiency.
So, I run just a two-stage direct-coupled 2A3 SET amplifier into a two - way mass-loaded ALTEC A7-800, with my own DIY speaker-level passive crossovers, film caps multiple-bypassed to get the music played back OK to my ears.
Have fun in the hobby, I still surely do !
You are correct sir. +1
Full range horns!
