Short answer: the Klipsch RP-6000F II for power handling, the Sony SS-CS3 if you need the lowest price. The RP-6000F II ranks #51 of 74 floorstanding speakers at $1,500 and stays clean at typical volumes, though it has worse baffle-step coloration than the RP-5000F II and a sibilance issue. The Sony costs $450 and its 88.6dB SPL at 2.83V/1m sensitivity suits budget AVRs, but resonances from 100Hz to 600Hz color male vocals.

Klipsch RP-6000F II: $1500 per pair Amazon eBay
Pros: Highest power handling and clean, well-behaved compression at typical volumes. Precise imaging from the controlled horn directivity. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 90dB.
Cons: Worse baffle-step coloration than the smaller RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have: a real regression in tonal balance despite the higher price. Bass extension is mixed (less deep at -3dB (67Hz) than the 5000F) and needs a subwoofer regardless. Narrow horizontal dispersion (~50-60 degrees).

Sony SS-CS3: $450 per pair Discontinued eBay
Pros: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Harmonic distortion remains reasonably low at moderate listening levels (86dB SPL) when high-pass filtered above 80-100Hz with a dedicated subwoofer. Front-ported design allows relatively close placement to front boundaries without excessive port occlusion. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments. Irregular frequency response peaks and dips make automated receiver room correction difficult to equalize effectively. Poor low-frequency extension (F3 of 72Hz, F10 of 39Hz) for a floorstander, combined with rapid distortion escalation below 80Hz at higher SPLs (96dB+). Supertweeter driver adds crossover complexity without providing audible high-frequency benefit within the human hearing spectrum. Discontinued.
