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.

A stupid idea.

It will mess up the image as it changes the group delays between the drivers.

Yah...like I said I figured it was dumb. So I guess I either live with the Maggies or inferior sound.

There are speakers out there that are better than some Magnepans. Which Maggie do you have?

It is not a dumb idea… and there are speakers out there you would enjoy more, like @russ69 said.

Of course I do because I often imagine bad things happening before I act. Maybe this is a silly habit of mine

Dino Game

I admit to putting Martin Logan SL3 electrostatics (&10" woof) on wooden dining room chairs, exactly where they normally sat on the carpet. Everything up 20".

Of course this was only during semi-free-for-all at-home parties we threw in my thirty's.  Otherwise I was civilized and sat down, along with the speakers...

Same history as above; planars for a long time, then good dynamic boxes, then great boxes. I also feel, adding up everything, they provides the least compromise.

I have a pair of older Genesis Genre I in a secondary system.  They are sloped back, which should tip the soundstage up but I always felt the images were lower than natural.  I put them on cinder blocks in my previous apartment and this did improve the sound in my opinion. I didn't import those cinder blocks to my new place so the Genesis speakers now sit on the floor and sometimes I'm keenly aware of they'd sound better if I put them back up on blocks.  So, it can be beneficial in some circumstances.
