Short answer: the JBL Stage 250B if sound quality matters most, the Pioneer SP-BS22-LR (Philharmonic AAM Mod) if price matters most. The JBL Stage 250B ranks #52 of 88 bookshelf speakers, rated 3.2/5, at $439.95. The Pioneer SP-BS22-LR (Philharmonic AAM Mod) ranks #61, rated 2.8/5, at $168, $271.95 cheaper.
Why pick the JBL Stage 250B: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The catch: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
The case for the Pioneer SP-BS22-LR (Philharmonic AAM Mod): 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. The catch: Some directivity error appears near the crossover frequency.
Buy the JBL Stage 250B if sound quality is the priority over the price, or the Pioneer SP-BS22-LR (Philharmonic AAM Mod) if the price is the priority over sound quality.

The Two Speakers In Full
JBL Stage 250B: $439.95 per pair Amazon JBL eBay
Older model: the JBL Stage A130 (ranked lower, rated 2.1/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Measured bass extension of 64.5Hz (-3dB).
Cons: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.

Pioneer SP-BS22-LR (Philharmonic AAM Mod): $168 per pair eBay
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. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 83dB.
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.
