Raising standmount speakers

Couldn't you just try a pair of 24" speakers stands? Many available in that height.

Also, the suggestion of a bit of tilt should tell you if you are on the right track. You could do the math to determine how much tilt. Or you could use something like a drywall square to do it by sight. Place the top of the "T" against the front (or back edge) of the speaker with the leg at tweeter height. Look where the "leg" is pointing. Should point to about ear level at your seating position when you have the tilt right.

Stand in back of the speaker with a small flash light or a laser pointer and hold it at the tweeter and see where it hits at your listening position. I have done this in my dimly lit audio room and it works great for level and direction. Some of the laser pointers even tell the distance which is great for us audiophiles.

Thanks for the suggestions. When I said 'without breaking the bank', I meant no more than $200-300. So this rules out buying a new pair of taller stands unfortunately.

I like the suggestion of creating a tilt, but I don't need to tilt just to find out if it makes a difference. I can slump on the couch a bit to get my ears a few inches lower than the proper sitting height. So the truth is that there's not a huge difference when I'm sitting upright or slump down a few inches. The main difference is that the music gets a tiny bit more immersive and the soundstage gets a bit taller when I lower my head. But I don't know if I can justify spending more than a few hundred dollars to get marginal improvements.

I do have the ability to raise or lower the footers, so that's something I'm going to try first. My only concern is stability. 

@yogiboy -- thanks for the IcoAcoustics suggestion. I didn't think of that before, but this might be a reasonable solution if the tilt doesn't fix the issue. 

What do you guys think of using thick butcher blocks underneath the speakers? I don't know how they impact the sound though. Probably a bad idea but who knows.

By the way, I've always heard that the tweeters should be aligned with your ears for best results. Is the advice always right, or is this one of the 'it depends' things?

I was going to suggest that under your stands. Not a long term solution, but would get you what you want.
