Hill Audio Gravo SWA-1510

Active 15’’ Sub

800W Class D Amplifier | Plywood Cabinet | Active Crossover

The Gravo SWA-1510 active subwoofer complements the Andante series of moulded speakers to perfection, adding the low bass punch that can only be obtained from a powerful driver in a solid wooden enclosure. Being a direct-radiating, vented design, it’s perfect for short-throw applications. A 15’’ driver with 3’’ voice coil and an optimized magnetic motor system provides great power efficiency, and adding the 770W class D amplifier module, it delivers an impressive low-end performance with high maximum SPL. Connection to sources and integration into systems is simple, with a stereo input provided, which is carried forward to a link output as well as a satellite output, the later subject to high-pass filtering (120/150Hz switchable). In this way, one or two satellite speakers can be connected, running the system in mono or stereo; further systems can easily be daisy-chained. The total system volume is adjustable, and the sub volume can be shifted against the main volume from -12 to +6dB. Made from 15mm birch plywood, carefully assembled and finished with extremely scratch-resistant black paint, this subwoofer is ready for the rigours of the road as well as the aesthetic requirements of installations.
