Klipsch RP-500M II Bookshelf Speaker vs Klipsch RP-600M II Bookshelf Speaker

Both are second-generation Klipsch Reference Premiere bookshelf speakers with the same 1-inch LTS titanium tweeter, 90° x 90° Tractrix horn and Tractrix port. The RP-600M II is the larger speaker: a 6.5-inch Cerametallic woofer against 5.25 inches, higher sensitivity (94 dB vs 92 dB), more power handling (100W vs 75W continuous) and deeper claimed bass. The RP-500M II is narrower at 6-7/8 inches and easier to fit on a shelf or desk. Owners and reviewers consistently describe the Klipsch horn sound as forward and dynamic, which suits movies and rock and can feel bright on long listening sessions. Buy the 600M II for a larger room or a system that plays loud; buy the 500M II for tight space or a subwoofer-backed setup.

• Choose the RP-500M II if your shelf or stand is narrow, your room is small to medium, or you plan to cross over to a subwoofer and don't need the extra low-end.
• Choose the RP-600M II if you have room for an 8-inch-wide cabinet and want more output, higher sensitivity and deeper bass without a subwoofer.
