Designed by Art Powers Sr., who, I understand, manufactured some of the older Lamm amplifiers and designed their loudspeakers, Madison Fielding's second-generation Flagstone all-weather speakers ($3500/pair) include down-firing 10" Eminence 150W active custom-made woofers, and claim a frequency response of 44Hz–15kHz ±3dB. The Flagstone series consists of two models and three variations, and claims to cover an area of up to 1000 sq. feet.
Heard with a Marantz SA 8005 SACD player, Parasound P 5 preamp, and A 21 amplifier, the sound was surprisingly good. Yes, my SACD pressing of Patricia Barber's Smash sounded a bit thuddy in the bass, and the image was low, but I expect that outdoors, with the woofers firing into a solid surface rather than springy carpet, the Flagstones will work a lot better.
