Short answer: the JBL 4305P for better sound quality, the Emotiva Airmotiv 6s for the lower price. The JBL 4305P ranks #16 of 62 powered bookshelf speakers at $2200. The Emotiva Airmotiv 6s ranks #60 at $400, $1800 cheaper.
What the JBL 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Tonality is neutral and non-fatiguing, vocal coloration is absent, imaging is precise, and the HDI horn maintains near-constant horizontal directivity above 2kHz. Each speaker is bi-amplified (125W LF + 25W HF), while USB, optical, balanced analog, AirPlay 2, Chromecast, Bluetooth and 24/192 wired interconnect make this an unusually complete system. Grilles caused no meaningful response penalty. Watch for: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room, so this is a near/midfield system rather than a high-output theater speaker. A baffle discontinuity produces a 1–2kHz directivity mismatch that cannot be corrected uniformly in the vertical plane; stay within about +/-5° of tweeter height. Soundstage depth and layering trailed the KEF Reference 1 Meta, and wireless speaker linking caps resolution at 24/96.
What the Emotiva Airmotiv 6s offers: 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. Watch for: 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.
Buy the JBL 4305P if sound quality matters more than the price. Buy the Emotiva Airmotiv 6s if the price matters more than sound quality.
If sound quality matters at all to you, skip the Emotiva Airmotiv 6s. It ranks near the bottom of the 62 powered bookshelf speakers, so look higher up the list instead.
