Description

Big sub-low end. 8-inch front-firing driver delivers smooth, accurate sub-low frequencies.

Bluetooth 5.0 stereo input ensures outstanding wireless audio quality.

Power to spare: 100W Class AB amplifier (50W RMS) delivers 100 dB SPL peak output (@ 1 meter) output with minimal distortion. That’s plenty loud!

Deep low frequencies: 30 Hz to 200 Hz frequency response.

Input gain control gives -30 dB to +6 dB of continuously variable output

Continuously variable lowpass filter keeps resonances in the 50 Hz to 130 Hz range.

Defeatable highpass filter (crossover) removes sub-80 Hz frequency content from the full-range signal sent to the main speakers for a perfect match.

Left and right, balanced ¼-inch TRS and unbalanced RCA main inputs ensure easy wired connectivity — or go wireless with Bluetooth.

Left and right balanced ¼-inch TRS and unbalanced RCA pass-through outputs onboard for connecting satellite speakers.

Polarity invert switch corrects phase-cancellation issues.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $11 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for PreSonus products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
