The Two Speakers In Full
JBL Stage 2 240B: $329.95 per pair Amazon eBay
Older model: the JBL Stage A120 (rated 2.5/5).
Pros: Two-way bookshelf with a 1” anodized aluminum dome tweeter in JBL’s HDI waveguide and a 4.5” polycellulose woofer crossed over at 1.4kHz. JBL rates it at 53Hz to 25kHz (±6dB) and 85dB sensitivity with a 6 ohm load. Espresso, latte and black ash finishes.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Rated bass stops at 53Hz (±6dB), so plan on a subwoofer for full-range listening.

Jamo S7-15B: $299.00 per pair Amazon eBay
Pros: Distinctive 7-degree tilted cabinetry, fabric-dome tweeter and a solid 4.52 raw local Spinorama score. With a subwoofer it reaches 6.66, while the compact format and magnetic grilles suit living-room use. Measured bass extension of 69.6Hz (-3dB).
Cons: Despite the 45Hz snapshot extension metric, Jamo specifies a conservative 71Hz +/-3dB bandwidth, so deep bass needs support. The four-ohm load and modest 86.3dB sensitivity require a capable amplifier.
