Pros: Erin calls these his favorite Klipsch speaker he has heard. With the tweeter trim set to -2dB, the listening-window response stays within roughly +/-1.5dB from 40Hz to just above 10kHz, and they produced genuinely powerful bass that reached about 30Hz in his room. The 8-inch woofer remains below 3% THD from 30Hz upward at 96dB/1m; compression is well controlled through about 90dB, and its limiter was not a concern at realistic listening levels. Exceptional all-in-one connectivity includes HDMI ARC, phono, USB, optical, Bluetooth, analog inputs and a subwoofer output; the Klipsch Connect app supplies useful bass/mid/treble adjustment.

Cons: The app’s flat setting leaves the treble elevated, and Erin preferred a -2dB tweeter trim. There is a likely tweeter/waveguide breakup feature around 16kHz, though he did not hear it. Horizontal coverage is narrow (about +/-30 degrees), prioritizing a focused image over room involvement; listeners who prefer a wider soundstage may not like that trade-off. Ear height matters: he recommends the reference plane between woofer and tweeter rather than directly on tweeter axis. The speaker begins limiting above roughly 90dB/1m, and the two cabinets still require a physical inter-speaker cable.

Emotiva Airmotiv 6s: $400 Discontinued

Emotiva Airmotiv 6s ranking card

Pros: CEA2034 spinorama shows lots of bass energy below 300Hz and the ability to play louder than a JBL 305P MKII comparison unit. Bi-amped design with 100W (tweeter) plus 110W (woofer) drives a 6.5” AirMotiv low-frequency transducer and AMT-style tweeter.

Cons: A suckout between 300-600Hz on the listening window is followed by a peak from 600Hz up. The built-in EQ options don’t fix this - one preset has the same dip plus a 3-7kHz peak. Vertical response droops at the 2.5kHz crossover. The reviewer’s verdict: there’s no reason to buy a speaker with a suckout in the upper bass if you have a choice. Discontinued.
