Revival Audio Sprint 4
2.5-way floorstanding speaker with an ARID dome tweeter and basalt BSC-7 midrange/woofer, designed for rooms of 30 to 60 m².
Description
The Sprint 4 is a 2.5-way floorstanding speaker intended for stereo listening in a living room. It combines a tweeter dedicated to the treble with two 18 cm drivers sharing midrange and bass reproduction, a configuration aimed at combining precision in the upper range with impact in the low frequencies.
The tweeter is a 28 mm soft dome fitted with ARID (Anti Reflection Inner Dome) technology, designed to limit internal reflections and refine high-frequency reproduction. The midrange/woofer drivers use a BSC-7 diaphragm with a basalt sandwich construction, a process that seeks a compromise between rigidity and lightness for responsive bass. Frequency response extends from 45 Hz to 22 kHz (+/-3 dB), with crossover filtering spread across two points, at 1.6 kHz and 2.2 kHz. With a sensitivity of 89 dB (2.83V/1m) and a nominal impedance of 4 ohms (minimum 3.8 ohms at 200 Hz), it requires a recommended power of at least 50 W, with a power handling of 180 W.

What to check before buying used
The basalt BSC-7 diaphragms deserve careful visual inspection: basalt and composite fibres can mark or crack on impact, unlike softer diaphragms. Also check the condition of the bass reflex ports and confirm there is no play or deformation in the suspensions of the 18 cm drivers, which affect how well the bass holds up over time. A test at gradually increasing volume can help detect any unwanted noise or distortion linked to driver wear.
