No, the 3070 is an active subwoofer, meaning it has a built-in 140-watt RMS amplifier. You can connect it directly to your receiver or pre-amplifier using an RCA cable.
The twin 170mm drive units work in tandem to move more air than a single driver, resulting in deeper, more controlled bass. This configuration, paired with the Helmholtz Pressure Equaliser, helps minimize distortion and ensures a punchy, cinematic low-end response.
The dual 170mm drive units allow the subwoofer to move more air than a single-driver model, resulting in deeper, more controlled bass. This configuration helps maintain clarity and impact even during intense movie sequences.
The unit uses a standard RCA input for connectivity. It is designed to integrate easily with most home theater receivers and stereo amplifiers that feature a dedicated subwoofer or LFE output.
Point-to-Point (P2P) bracing reinforces the internal structure of the cabinet. By minimizing unwanted vibrations and cabinet resonance, it ensures the bass remains tight and accurate rather than muddy.
P2P bracing is an internal structural reinforcement technique that stiffens the cabinet walls. By reducing cabinet vibrations, it ensures the sound remains clean and precise, preventing unwanted resonance from coloring your audio.
The 3070 uses standard RCA connectivity, making it compatible with most home theater receivers and amplifiers that feature a dedicated subwoofer or LFE output.
With a 140-watt RMS output and dual drivers, the 3070 is well-equipped to fill medium-to-large rooms with impactful bass. Its performance is best suited for home theater setups where you want to feel the scale of blockbuster sound effects.
HPE technology is designed to equalize the pressure within the cabinet. This reduces the 'boxy' coloration often found in subwoofer enclosures, leading to a cleaner and more natural low-frequency response.
