so if i have a 8ohm crossover designed for a single 75/150 and ss9700 and double it up,this is good??another words,use one for the upper mid/hi and one on the lower? MTTM

Why do you want to use two tweeters? It's completely unnecessary.

If you've got a good crossover design for using one mid and the tweeter, then why not go with that?

Even if you were to wire the two mids together, and create an MTM, there wouldn't really be any point as the tweeter wouldn't be sensitive enough to match the mids output.

...and lobing in the mids, and blurring the image

So, you want to spend a lot of money in something you don't know. For a start, what kind of 3-way are you using, ideas, speakers, room size, stereo? And you have the idea of using what you already have, do you have woofers?

You can mount a second tweeter and it won`t but useless, but only if mounted on the backpanel. Opera loudspeakers from Italy do it, if your backwall is at least 1m away of your loudspeakers the effect of the second tweeter will be worth. They have started to sell a configuration where they use two tweeters and one midbass, however I have not heard anything of this line yet and cannot comment it.

this is what i currently have
2-ATC 75/150/side
2-SS 9700/side
2-Volt 3143/side
i already have a passive 24db/380hz for woofers and works well BUT when i originally started i had a single mid/hi at 24db/3800hz in a 10x10 listening area and now it is 13.5x22.
So i talked with Chris at Solen and he just sent another mid/hi crossover...hense here i am 2yrs later.
Chris designed all the x-overs and i am not nocking his work but i am wondering about some different cap/designs for the mid/hi only ,maybe if anyone has previously tried such a project they may give some ideas....
I realize the many problems invoved with MTTM,..MTM/SUPER TWEETER or others.
I beleive if someone can build it so can I...DIY
we are all here because we are tired of paying $10-100,000 for someones speakers,maybe one day but not today.
Ever since i seen what a PMC IB1 looked like inside and the cost of the $100 mid/hi in a pair of $10,000 speakers...well i am here building my own and unfortunately, like a 69Dodge Roadrunner with a 440/six pack...I LIKE TO CRANK IT UP ON SUNDAY(LOL)
any help or experience would be appreciated...i would post pics but i am slow on the computer,so if you would like to help you can e-mail and i will send some pics of wher i am at...PM me
I am learning the that there are different caps for different sounds,but have much to learn
thanks john

Hi Mario,I thought about using a pair of Fostex attenuators untill i find my happy point(s) and swapping them out later....this concept(simular to Von Schwiekert,Wilson,Genisisetc.) alows for great levels of clean,clear spl.
I am puchasing a Mark Levinson 333 and 331 to try out and i have a Classe CA300 and Sim Audio Titan for some comparisons(the ATC mids are very picky)

Chris @ Solen made even more money out of your gullibility.
