I am an actual owner of one of the best valued passive floor standing speakers EVER made! These three-way four driver towers deliver one of the widest frequency ranges combined with an astonishing 96db sensitivity!! That means these speakers can be driven with minimal wattage from your amplifier, but it also means you can play your music or watch your movies at higher levels with less distortion. The frequency range is 25hz to 23,000khz. With a maximum of 250 watts, these speakers sound best with at least a clean 100 Watts of power. At 1299.00 a pair, this system is impossible to match in how it?s sounds! Rich beautiful mids, point accurate highs, and that Bass!! A subwoofer is simply not required. The included spikes and spike plates are almost impossible to set up on a hard floor, so I fashioned my own ?plates? from a carpet like material that had a foam rubber backing, cut into one inch squares. The Grills are made very nicely, and attach magnetically. But for music listening, leave the grills off. My KLH Kendall?s are driven by the Yamaha AS-801(100w per channel @ 8ohms). This combination is an almost perfect pairing both in keeping the cost down and most importantly, sonically! The smaller footprint of the Kendall?s (Less than 8 inches wide), helps to produce the wonderful soundstage as the speakers themselves become transparent, disappearing in all of the luscious sound they deliver. In closing, the KLH Kendall Floor Standing Speaker system, may very well be the last speakers you?ll ever buy.....they are simply......that good!
