Short answer: the KLH Model Five on measured sound quality, the Klipsch RP-8000F II on price. The KLH Model Five ranks #125 of 228 floorstanding speakers, rated 4.0/5, at $2,998. The Klipsch RP-8000F II ranks #138, rated 3.9/5, at $1,099, $1,899 cheaper.
The KLH Model Five is the deeper-bass pick. A retro styled sealed tower with a wide, spacious soundstage, low distortion and useful treble adjustments for your room. Its bass reaches about 52Hz before falling 3dB, against 67Hz for the Klipsch RP-8000F II. Watch for: On-axis response is visibly irregular because the wide vintage baffle creates diffraction, and the upper/lower midbass mismatch around 200Hz can sound lean away from the intended wall placement.
The Klipsch RP-8000F II is the more accurate choice. A very easy to drive tower with twin 8 inch woofers that stays clean and composed at high home theater volumes. Its measured preference score, a predictor of how neutral it sounds, is 5.39 against 4.76 for the KLH Model Five. The tradeoff: Mid-bass sounds lean despite the dual 8-inch woofers, and bass extension disappointed for its size: expected to reach 50Hz, didn’t get there in-room.
Buy the KLH Model Five if sound quality is the priority over the price, or the Klipsch RP-8000F II if the price is the priority over sound quality.
