Short answer: the JBL Studio 530 for better sound quality, the Pioneer SP-BS22-LR (Philharmonic AAM Mod) for the lower price. The JBL Studio 530 ranks #23 of 56 bookshelf speakers at $399. The Pioneer SP-BS22-LR (Philharmonic AAM Mod) ranks #33 at $168, $231 cheaper.
What the JBL Studio 530 offers: CEA2034 spinorama shows a fairly flat on-axis response. Watch for: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz.
On the Pioneer SP-BS22-LR (Philharmonic AAM Mod) side: This is Dennis Murphy’s “Affordable Accuracy Monitor” (AAM) mod of the discontinued. Set against that: Some directivity error appears near the crossover frequency.
Buy the JBL Studio 530 if sound quality matters more than the price. Buy the Pioneer SP-BS22-LR (Philharmonic AAM Mod) if the price matters more than sound quality.

The Two Speakers In Full
JBL Studio 530: $399 Discontinued
Pros: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off.
Cons: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time. Discontinued.

Pioneer SP-BS22-LR (Philharmonic AAM Mod): $168
Pros: This is Dennis Murphy’s “Affordable Accuracy Monitor” (AAM) mod of the discontinued, budget Pioneer SP-BS22-LR: the stock tweeter is swapped for a Peerless BC25TG15 dome and a redesigned 3rd-order crossover is built to match it to the stock 4” woofer. CEA2034 spinorama shows only small variations from a flat on-axis response with some directivity error near the crossover, a marked improvement over the unmodified Pioneer, which the reviewer notes shows much more variation from flat. Distortion at 86dB SPL/1m is reasonably controlled above 200Hz, and tweeter distortion barely rises even at 96dB SPL/1m.
Cons: Some directivity error appears near the crossover frequency. Distortion climbs in the woofer’s range (below 200Hz) at both 86dB and 96dB SPL/1m. Minimum impedance dips to about 5 ohms with a couple of resonance peaks. This is a DIY project, not a finished retail product: Murphy sold ~$168 pre-built pairs for a while but no longer does, so it now requires sourcing a used/discontinued Pioneer SP-BS22-LR pair plus building the crossover and swapping the tweeter yourself. The mod itself is public domain, but there is no current turnkey way to buy this speaker.
