The CLA-310 Compact 3x10 Line Array Subwoofer delivers focused low-end reinforcement for sound engineers running small to mid-size line array systems. Built specifically for venues where traditional subs are too bulky but bass extension is non-negotiable.

This passive subwoofer houses three 10" drivers with 2" voice coils and 50 oz magnets, handling 400 watts RMS and 800 watts peak power. The 40Hz-500Hz frequency response provides the foundational bass that pairs seamlessly with full-range line array elements.

At 8 ohms impedance with 102 dB sensitivity, the CLA-310 delivers 128 dB maximum SPL while maintaining efficient power transfer from your amplifiers. The compact 11.75" x 18.75" x 27.5" birch plywood enclosure weighs just 71 pounds, making it manageable for mobile setups. High-intensity aluminum suspension hardware enables both ground stacking and line array frame mounting configurations.

Churches, schools, gymnasiums, and clubs benefit from the CLA-310's focused 90° x 50° coverage pattern. The system handles venues up to 300 people when properly amplified and arrayed. Works effectively as front-of-house reinforcement or side-fill support depending on your coverage needs.

Dual Speakon inputs provide flexible daisy-chaining options with standard speaker cable. The unit ships ready to connect to your amplifier or powered mixer.

Seismic Audio backs the CLA-310 with a one-year warranty and ships direct to keep professional-grade line array components accessible for working sound engineers.

Frequently Asked Questions

How many people can the CLA-310 subwoofer handle?

The CLA-310 effectively reinforces bass for venues up to 300 people when properly powered and positioned. For larger crowds, multiple units can be ground-stacked or frame-mounted together. The 128 dB maximum SPL provides substantial low-end impact for most small to mid-size applications.

What amplifier power do I need for the CLA-310?

You'll want an amplifier capable of delivering 400-800 watts into 8 ohms to properly drive the CLA-310. Most professional power amplifiers or powered mixers with sufficient wattage will work well. Match your amplifier's 8-ohm rating to the subwoofer's power handling for optimal performance.

What cables do I need to connect the CLA-310?

The CLA-310 uses standard Speakon connections, so you'll need Speakon-to-Speakon speaker cables. The dual Speakon inputs allow daisy-chaining multiple subwoofers from a single amplifier channel. Standard 12 or 14 AWG speaker cable with Speakon connectors handles the power requirements effectively.

Can I use the CLA-310 without other line array speakers?

While the CLA-310 is designed to complement full-range line array elements like the CLA-2x5, it can work as standalone bass reinforcement for existing PA systems. The 40Hz-500Hz response focuses purely on low frequencies, so you'll need main speakers to handle mids and highs for complete coverage.

How does the CLA-310 mount in a line array system?

The CLA-310 features high-intensity aluminum suspension hardware that allows both ground stacking and frame mounting with compatible line array rigging systems. Side pocket handles make transport manageable, and the compact birch plywood construction keeps weight reasonable at 71 pounds per cabinet.
