Avantone Pro CLA-Sub: An NS-10-styled Studio Subwoofer
Extend the low-end of your classic monitor system.

The Avantone Pro CLA-Sub is the perfect subwoofer to add to your CLA10 monitors, but you can add it to any studio monitor setup for extended bass.
Avantone Pro is renowned for resurrecting classic audio designs and modernizing them with uncompromising quality standards. Whether it’s mics or monitors, you can trust that every detail has been considered to give you the best audio reproduction possible at a reasonable price.

The new CLA-Sub is a 300-watt studio sub with a 10-inch dual-magnet driver that can be configured in front or downward-firing modes. Housed in a ported enclosure, the paper cone driver system offers extended low-end response with minimized distortion. To optimize the input signal, there is a variable high-cut filter (50-180 Hz), so you can adjust the frequency range being sent to the sub.
In addition, if you need to send signals to studio monitors, there is a low-cut filter that can be set at 80 or 100 Hz to match the size of your monitors. For convenient operation while mixing, you can also use a footswitch, and there is a power-saving mode for efficiency. If you’re wondering about the difference between the front and downward-firing modes, you can switch between them by redeploying the rubber feet accordingly.
Front-firing gives you the cleanest possible results, while downward-firing couples with the floor so you get a bit of extra oomph. To cater to different setups, the CLA-Sub has a pair of XLR combo inputs and a pair of XLR thru ports. Meanwhile, there is also a polarity inversion switch in case you need it.
Overall, the CLA-Sub is an impressive addition to the Avantone Pro lineup and the perfect companion for your NS-10 style monitors. For most producers and engineers, the bass response is a major weak point of the NS-10, so this makes the CLA-Sub an ideal solution for helping these classic monitors to remain relevant in 2026.
