UPDATE- I know this update is not that important but why not. Im not active at all on this forum since im on other non-audio related forums, but I posted this thread in 2017, its oct 2020 and my speaker set with the 4 super tweeters wired per speaker box (8 in total) are still going great and strong. So by wiring 4 super tweeters properly to a 3 way cross over per speaker box(thanks for informing me of this on this thread) instead of 1 tends to increase the life of the tweeters.
Actually I had to replace the foam around the 2- 15" bass sub woofers with new foam rings using Guerrilla wood glue and it worked great. (had to hold the foam down with weight for 1 day to allow glue to dry).
My 17(or more) year old Sony receiver finally broke down and went into permanent protect error mode so I bought a new Sony receiver, I really nice one with amazing low bass frequencies, Sony STR-DA3100ES.
My old EQ started to hum way too loud(problem started 10 years ago and got louder and louder) so I bought an excellent Technics EQ SH-Z200. As I mentioned on this thread, I use 2- 10 inch bass woofers as the midranges but since the midrange is really loud on 2- 10", I always turn them around and not facing so the midrange would be lower. With my new Technics EQ I lowered a certain level of midrange and the 10 inchers finally sound perfect when facing the front, for some reason when I lowered the midrange on my older EQ it didn't sound perfect enough to allow me to turn them around, whereas with the new EQ it does.
My 3 way crossovers are still working great but before I bought my new EQ I bought 2- 2 way crossovers to see how my super tweeters would sound like without using the 2- 10 inch woofers as mid ranges. The bass sounded perfect but the super tweeters had a very loud and annoying high midrange sound and sounded bad, so I had to reconnect the 3 way crossover back to the way it was.
I HAVE A NEW QUESTION. I notice 2 way crossovers are really popular and sold everywhere. I know you connect 2 speakers to a 2 way crossover, a bass woofer, but what kind tweeter or midrange do you connect to the crossover as the highs? Although im happy with my 3 way crossover the way it is sounding great with my new EQ, but im still curious about what 2 speakers do you wire to a 2 way crossover. If you wire a midrange speaker there will be no tweeter highs, and if you wire a tweeter or super tweeter there will be an annoying loud mid range. Are there speakers for a 2 way crossover that I don't know about??
