Short answer: the JBL 705P for better sound quality, the Dayton Audio M4 for the lower price. The JBL 705P ranks #22 of 60 powered bookshelf speakers at $1998. The Dayton Audio M4 ranks #28 at $249.98, $1748.02 cheaper.
What the JBL 705P offers: CEA2034 spinorama shows flat response with excellent directivity, similar to its larger 708P sibling. Bi-amplified 500W design (250W woofer, 250W compression driver) into a 5” woofer and JBL’s 2409H compression tweeter. Watch for: A cancellation around 750Hz (likely port-related) and a bit of boosted response at the 1.75kHz crossover show up in the on-axis curve. Sits right around the ear’s most sensitive hearing range near 100Hz, so that region is partially audible even at modest levels.
What the Dayton Audio M4 offers: Good build quality. Has a subwoofer output for extending the low end. Overall linearity is decent for the price. Avoids sibilance since it’s slightly recessed right in the harsh 4-8kHz region. Watch for: The amplifier is only in the left speaker, so it’s not separate amps in each unit. Bass doesn’t extend very deep, and unlike some rivals it doesn’t use DSP to boost the low end. Sounds noticeably different up close versus at a normal listening distance, with a softer treble near field and a more recessed upper midrange farther away. Limited output headroom - distortion rises sharply above about 93dB, so it’s better suited to near-field or desktop use than as a far-field living-room speaker.
Buy the JBL 705P if sound quality matters more than the price. Buy the Dayton Audio M4 if the price matters more than sound quality.
