Raised Towers

Depends. Do you do your listening while standing up?

Considering that tweeters are generally designed to be at or around ear height, no I haven't.

That being said, I have seriously considered elevating one of my subwoofers. Because they aren't directional, having one close to the ceiling or midway up a wall, might make for a more homogenous distribution of bass pressure throughout the room.

The tweeters have pretty good dispersion so that may not be an issure.

I'm wondering if raising them could make them seem more "spacious". 

I'm thinking about trying to kick the Magnepan habit...but then I listen to cones in boxes...they sound like cones in boxes. Trying to have my cake and...

I know there are other threads about putting them on spring isolated stands… for about $1500/speaker..

sheesh..

looking at some acoustic isolators for about $100 a speaker + platform materials as a diy project just to see if I hear any difference.. 

I need to make some anyway for a couple tube monos.  Just don’t know if I want to try a rubber (natural) base, spring isolator or suspension isolators..  

Just wish the weather would hurry and warm up.. shop is expensive to heat right now..

Unlikely to make them sound better. Your going to move the sweet spot above your head.

I used planar speakers for about 35 years. I have heard Maggies of all types for at least 40 year, come close to buying them more than once. I moved to dynamic (box) about fifteen years ago for reasons that to me outweighed the benefits of planar.

After listening extensively to acoustical instruments and attending hundreds of classical concerts I found the reasons the vast majority of people invest in dynamic speakers and to me the advantages greatly outweight the disadvantages. But you have to get good ones.

If you want dynamic speakers to have the attributes of planar… then put a set of super tweeters on top of your towers. That is what is missing… the effect of frequencies above hearing level impacting the frequencies you hear (well and adding some fine detail).

For listening standing, my platforms can change the angle of speaker. Otherwise they have pretty large footprint for higher stands.
