Raising standmount speakers

My main system is in the media room and consists of Harbeth SHL5+ resting on stands that are 18 inches high (as recommended by Harbeth). When we were building the house this room was meant to be a proper media room. So we had the builder make a platform in the back 1/4th portion of the room to get the stadium seating effect. The platform is about 8 inches higher than the rest of the floor area. My listening chair (actually couch) is placed atop the platform. The problem is that in this listening position my ears are a little above the tweeter level.

I'm looking for suggestions on how to raise the speaker stands by 4-6 inches without breaking the bank or the aesthetics of the room. The room is fully carpeted by the way.

P.S. - please don't suggest removing the platform. We still plan to put a theater setup in there some day ... although, I'm running out of excuses to postpone the decision. I would much rather keep it as a dedicated 2-channel listening room, but the rest of the family is not too thrilled. The thought of just getting rid of the family has certainly crossed my mind though ...

A bit of 'tilt' (shim ... fraction of an inch) to adjust the angle to proper height.
My guess would be that the eight inch rise would not have a great effect.
Does the speaker not sound right?
Seating at a poor acoustic position would make a difference regardless of the type of system ( 2.0, 2.1, 5.1).
The platform could be resonant though.

Tilt the fronts of the speakers up a tiny tad.

If the footers on your stands are adjustable just raise the front, or lower the back (footers).

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.
