Product Description

The all new TS312 powered subwoofer extends the bass response of virtually any full- range speaker, relieving that speaker of the difficult task of having to reproduce the low bass frequencies. The result? A system with stunning wide-range response characterised by dramatic, impactful low frequencies and effortless, undistorted mids and highs. The listening audience will hear everything with perfect clarity, from the lowest bass synth tones to the highest percussion bells and everything in between. 

• Driver: 12-inch with high-temperature, long-throw voice coil
• Amplifier: 1000W continuous, 2000W peak Class D power
• XLR outputs, with six discreet output modes for ideal matching with companion speaker
• Extended LF switch for increased EQ control
• Electronic clip, thermal and transducer overdrive protection
• Integrated 35mm pole socket
• Rugged, mar-resistant splatter-spray finish always looks good, even with heavy use
• Designed and tuned in the USA

Bang for your buck!
This new sub from alto is amazing. Great sound, especially when run with alto tops. The inbuilt dsp allows you to tell the sub exactly what tops your running and adjusts the output to match. Great product at great value.
