atc sm75 and hiquphon ow II

[leifislive]

Hi,

i came about the idea to use the atc sm75 and hiquphon ow II, yet I am a little bit concerned about polar pattern response behavior due to a >3k crossover point.

this will be an active 24dB project.

afaik the atc 75 needs a 154mm hole to be mounted in and the owii is 92 mm, therefore a minimum at 30 degrees can be expected at 2750 hz.

my question would be:
what do you think of that combination?
what crossover points are you using for the atc?
how close can you bring any tweeter to the atc, before havig problems due to the two magnet systems?

not related to this, but, is there any benefit using the s version, when i am usually listening to levels not exceeding 90dB?

thanks for your answers

I appreciate any comment


regards
