The Magneplanar 1.6 are tall but only 19" wide and 2" deep.

But they need about 1.5 metres of space behind them!

And a Krell to drive them?

No, despite urban mythology, they're an easy load, but they do need
*lots* of power. One of the big Rotels or NADs is probably the ideal
partner.

I have no problems driving paralleled Maggies with a homebrew hybrid
tube/MOSFET amp that puts out ~20 volts rms. The power supply is
800VA. And then some people say power supplies aren't important :-)
That's "50 watts in 8 ohms". The Maggies are MG1 improved and SMG-A.
