So how do these sound since you reference them as I assume you would not reference something you have not heard. 1 Quote Link to comment Share on other sites More sharing options...

Actually , it's the opposite ! the Chinese made Piezo tweeters are Higher Quality since the CTS Ceramic to make piezo tweeters is local , and without the CTS product or the Motorola tooling , no one can manufacture piezo tweeters , let alone knockoffs or clones . the MCM 1900 piezo tweeters were made by CTS /Motorola in Mexico or China , the Mexico tooling was sold to a 1/3 party , the Chinese tooling remains in China , for obvious reasons . https://www.ctscorp.com/products/piezoelectric-products/ Quote Link to comment Share on other sites More sharing options...
noviygera Posted July 4, 2022 Author Share Posted July 4, 2022 So these piezo tweeters sound good? I've never used one so some feedback on the SQ would be appreciated. Also, keeping the single K55v is enough? Quote Link to comment Share on other sites More sharing options...
OO1 Posted July 5, 2022 Share Posted July 5, 2022 yes , as an example , the MCM 1900 used 5 piezo tweeters per side , so 10 total http://www.ss427.com/MCM-1900.pdf Quote Link to comment Share on other sites More sharing options...

noviygera Posted July 24, 2022 Author Share Posted July 24, 2022 It’s slowly coming together now that i have the Jbl cinema subs. There are two possible versions: As you see, Which stack would you pick and why? Quote Link to comment Share on other sites More sharing options...

The stack on the right side places the tweeters about seven feet high. That might be too tall? Get some metal mesh grill covers if the woofers are going to be exposed to party people and other wild animals! 2 Quote Link to comment Share on other sites More sharing options...
noviygera Posted July 24, 2022 Author Share Posted July 24, 2022 Seven feet high may be OK but on the tall side. Definately, grills will be installed. My concern is the 400hz xover and the matching of double versus single midbass to the mid/high section. Quote Link to comment Share on other sites More sharing options...

If you have a separate amp channel for each section, then just adjust the single or double woofer SPL to blend with the subs and with the mids and highs.

Marvel Posted July 25, 2022 Share Posted July 25, 2022 I assume you will have a midrange/tweeter section for the stack on the left... What woofers are in the LS cabinets? Quote Link to comment Share on other sites More sharing options...
noviygera Posted July 27, 2022 Author Share Posted July 27, 2022 Marvel, K43 woofers in the LS cabinets. Yes, there is a left mid/high section for left stack as well! Actually, I took them apart: My K55v drivers came with a pair of spare diaphragms. What I discovered is the dipahrams inside my K55v are different from the spare set. The voice coils are much different. See photos. Can you help identify? What's what here? Are the higher power diphragms installed and the original set is spare?

noviygera Posted July 27, 2022 Author Share Posted July 27, 2022 I think I need help identifying if I should keep the diaphrams installed with the larger VC or replace with the spare set that has the shorter VC. Quote Link to comment Share on other sites More sharing options...
OO1 Posted July 27, 2022 Share Posted July 27, 2022 the diaphragm on the left is the right one if it reads D-20GB . Quote Link to comment Share on other sites More sharing options...

Send him a couple of pics and he is sure to help with accurate info. Quote Link to comment Share on other sites More sharing options...
