If I may add to what Mark said.
The Maggies sound great, but they need room in the back and on the sides.
A ballpark of about 3ft+ off the rear wall and 4ft+ on the sides.
They are also 6ft tall...If you're married that may not fly with the wife.
Of the two speakers (if using that receiver) and sensitivity of the Triton Two is at 90 dB. Impedance runs a little low, hitting a minimum of 2.9 ohms at 3 kHz and averaging about 5 ohms. Maximum impedance phase shift is -46° at 20 kHz-not an extreme shift, and not at a frequency where there's a lot of energy. (got that from a review.)
I'd get the Tritons and a pancake fan to pull air up and out of my Denon.
Just my $0.02
