You are so right. Most just kind of scold you verbally and think your nuts:)
Acoustic Zen Crescendo speaker crossover capacitors ... who makes them?
I own the MKl version of the Crescendo and see the crossover uses all Acoustic Zen branded capacitors. Most are blue in color with the smallest values bring black. Does anyone know what company makes these for AZ? I did email the builder, but no answer. Love any information the community may have on this topic.

Ok, I finished the upgraded crossover board and just installed them. A ton of work. Imagine replacing caps that are 1/2 inch in diameter and 2.5 inches long with caps almost 6 inches long and 4.5 inch diameter! Had to get it all to fit into the same space. Initial results seem most excellent. The thing I noticed within 20 seconds was the absence of noise, music flowing out of a dead quiet backdrop. The difference over the standard crossover is astounding in this regard. Already I hear more resolution combined with greater space, body, texture and improved natural tone. I also hear a greater sense of ease and natural flow. Only 2 hours thus far. I will report back after 24 hours. i will try and post pics in a link as you have to see the before and after. |
This link should take you to a slide show. The first pic and last are the original board with no upgrades. http://s1097.photobucket.com/user/grannyring1/slideshow/ |
There is also an additional board on the very bottom of the speaker that I have not touched as yet. It is for the bass drivers. Unfortunately it contains two 1000uf electrolytic caps! The two resistors on the bass board are sand cast and will be replaced with Mills MRA 12. As for those 1000 uf caps I will think on my plan of action. I cannot believe how many parts are in this crossover. This is not your simply first order type. I believe it is a 3rd order Linkwitz/Riley design. |
This is the amp I am using to drive them right now. It started its life as a Cary Rocket 88r. I modified it to the hilt with.... - all high quality film caps in the power supply (Clarity TC, ASC, Obbligato) and increased the capacitance. Needed to add a wooden expansion chassis to fit the film caps in the power supply. A double decker build. - Arizona capacitor blue cactus coupling caps - Western electric NOS hook up wire - Mills MRA resistors - Moved the RCA jacks right next to the input tube and also made more direct connection in addition to shortening the signal path - removed all electrolytics caps and replaced with Clarity and Theta caps. - removed binding posts and use Teflon posts to "clamp" the output transformer leads directly to the nude speaker cable. - direct soldered high quality power cord There is more, but you get the idea.... Here are some pics. http://s1097.photobucket.com/user/grannyring1/slideshow/Cary%20Rocket%2088r%20upgrade%20and%20mod |
