Description:
Selling a professional, high-end Neumann KH 810 active subwoofer in excellent working and cosmetic condition. This unit has been operated exclusively in a clean, smoke-free, structurally dense studio environment. It has been meticulously cared for and never driven hard or abused.If you are running Neumann KH 310 or KH 120 monitors, this is the native, acoustically perfect companion subwoofer designed to form a completely seamless, phase-aligned monitoring system. Due to a recent studio downsize and relocation into a highly treated concrete room, this massive unit is simply overkill for my current monitoring needs, forcing a reluctant sale.Key Features & Technical Highlights:

• Built-in 7.1 Bass Management Console: This is not just a standard subwoofer; it features a comprehensive bypassable 7.1 surround sound bass management matrix with balanced XLR inputs and outputs, making it the perfect centerpiece for professional Dolby Atmos, post-production, multi-channel surround, and high-end broadcast facilities.
• 4-Mode Bass Management: Offers maximum flexibility for traditional stereo or advanced multi-channel routing.
• Pristine Transient Response: Engineered to remain completely linear and undistorted down to 18 Hz, allowing you to accurately track and mix critical low-end sub-frequencies.
• Acoustical Controls: Integrated 4-position bass equalizer and continuous phase control (0 to 270°) to perfectly tune the sub to your room's acoustic profile.

Condition & Cosmetic Note:

• Cosmetic: Rated as Good / Standard Studio Used. The chassis shows visible cosmetic scuffs, surface scratches, and edge wear across the cabinet casing from normal studio handling and placement (please review the detailed photos closely to see the exact cosmetic condition). There are no structural cracks or deep gouges in the wood cabinet, and the front speaker grille mesh remains fully intact.
• Functional: 100% operational and rock-solid. While it shows cosmetic signs of a working studio life, it is perfect where it counts. All XLR inputs/outputs, the back-panel gain/phase pots, and the internal amplification stages function flawlessly with zero signal degradation or line noise.

Shipping & Logistics Policy (Europe-Wide):

• Free Shipping Included: Price includes fully tracked, premium express ground courier shipping (UPS/DHL) anywhere within the European Union (EU).
• Safe Shipping Insurance: Full transaction value protection/insurance is entirely baked into the checkout price for absolute peace of mind during transit.
• Packaging: The unit will be heavily over-packed using thick, industrial-grade, double-walled box reinforcement and custom high-density foam padding to insulate the heavy 26 kg chassis from any shifting or courier drops.
