Is there any stat speaker to stick on the wall?

thanks you all for these suggetions.
Really useful.....

VMPS ribbon monitors can be pretty close. My RM30s can be placed against the wall and will still sound terrific. Among the most beautiful cabinets, too.

Yes Magnepan's model is great for a budget speaker, they only sell internet direct but you can do 6 surrounds and a center for I think $1200 get an HSU Research sub and amps that have some power, and everyone is happy.
Martin Logan also makes wall mount speakers.

Magnepan has their MMG-W model for wall mounting. It's a planar magnetic rather than an electrostat, but it might do what you want...

Electrostatics, like most planar speakers, are typically dipole radiators, and therefore emit some sound to the rear of the speaker.

Because of this, amoung other reasons, they're are usually not designed to function properly next to a wall.

For other advice, it would help to know more about your musical preferences, size of listening room, your listening habits, and/or equipment you have liked or disliked in the past.

Ultimately, if your family maintains veto power over your speakers, you could be in the wrong forum.
