Short answer: the JBL 4305P for better sound quality, the Focal Alpha 65 EVO for the lower price. The JBL 4305P ranks #14 of 40 powered bookshelf speakers at $2200. The Focal Alpha 65 EVO ranks #16 at $499, $1701 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. 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.
The case for the Focal Alpha 65 EVO: Very neutral, not quite as good as the Klasik 2020 in the midrange, but with better soundstage and instrument definition than the HS8. The tradeoff: Ignores sub-bass, and the LF/HF trim dials lack a center detent so getting back to flat takes trial and error.
Buy the JBL 4305P if sound quality matters more than the price. Buy the Focal Alpha 65 EVO if the price matters more than sound quality.

JBL 4305P: $2,200/pair Amazon JBL
Pros: 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.
Cons: 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.

Focal Alpha 65 EVO: $499.00 Amazon
Pros: Very neutral, not quite as good as the Klasik 2020 in the midrange, but with better soundstage and instrument definition than the HS8
Cons: Ignores sub-bass, and the LF/HF trim dials lack a center detent so getting back to flat takes trial and error. The reviewer’s original sample showed an odd distortion spike between 1.5-8kHz at 86dB SPL, though a second sample from Focal didn’t reproduce it - likely a defective unit rather than a design flaw.
