Klipsch PRO-800SW In-Wall / In-Ceiling Subwoofer (Each) at Vinyl Sound Toronto Canada

The PRO-800SW is a passive 8" in-wall and in-ceiling bandpass subwoofer from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Part of Klipsch's Professional Series architectural audio lineup, it is purpose-built for whole-home audio, distributed audio, and small to medium home theater installations where a completely hidden, minimal-footprint bass solution is required. The PRO-800SW uses an 8" Long-Throw Cerametallic Dual Voice Coil Woofer in a sealed MDF enclosure with a bandpass port tube, covering a frequency range of 38Hz to 125Hz (+/-3dB) at up to 125W RMS and 300W peak at 8 ohms. The bandpass design routes all output through a flexible port tube that terminates in a 4.25" ceiling or wall opening, matching the diameter of standard recessed down-can lights for a visually seamless installation. The Dual Voice Coil driver design provides maximum wiring and system configuration flexibility for multi-zone and custom installation applications, and the optional 4" x 10" Floor Vent Kit accessory allows the port tube to terminate through a floor register for below-floor cabinet installations where ceiling access is unavailable.

Bandpass Design and Minimal Visual Footprint

What separates the PRO-800SW from conventional in-wall or in-ceiling subwoofers is its bandpass acoustic design, in which the 8" Cerametallic driver operates inside a fully sealed MDF enclosure and all acoustic output is channeled through a flexible port tube rather than through an open driver face. This approach allows the cabinet to be positioned inside the wall cavity, above the ceiling, or below the floor, with only the small port tube termination visible in the finished room. The 4.25" grille opening at the port termination matches the diameter of most standard recessed down-can light fixtures, creating a visually minimal footprint that integrates naturally into the ceiling plane without drawing attention. Both a round magnetic grille and a square magnetic grille are included in the package, allowing the port termination to suit either a circular recess or a rectangular register opening. The sealed main cabinet and the port tube design together also help isolate low-frequency energy from adjacent rooms, a meaningful benefit in multi-room residential builds.

Dual Voice Coil Woofer and Placement Versatility

The 8" long-throw Cerametallic cone woofer in the PRO-800SW is wound with a dual voice coil, giving system designers multiple wiring configuration options including series, parallel, or independent coil connections to suit different amplifier channel assignments and impedance requirements. This makes the PRO-800SW especially well suited to multi-zone distributed audio systems where a single subwoofer unit may need to serve more than one amplifier channel, or where impedance optimization across a multi-speaker network is required. The Cerametallic cone material is rigid and lightweight, enabling high excursion with low distortion across the 38Hz to 125Hz operating band. Klipsch's KDA Series DSP amplifiers include factory-configured equalization and limiter presets engineered specifically for the PRO-800SW's driver and bandpass enclosure combination, delivering optimized acoustic performance and driver protection when used as the matched amplification solution. The optional 4" x 10" Floor Vent Kit, sold separately, connects to the port tube to allow termination through a standard floor register when the cabinet is positioned in a below-floor or under-stair location, adding a further installation option unavailable with conventional in-wall subwoofer designs.

Frequently Asked Questions

What is the Klipsch PRO-800SW?

The Klipsch PRO-800SW is a passive 8" in-ceiling and in-wall bandpass subwoofer from Klipsch's Professional Series, rated at 125W RMS and 300W peak at 8 ohms, with a frequency range of 38Hz to 125Hz. It uses an 8" Long-Throw Cerametallic Dual Voice Coil woofer in a sealed MDF enclosure with a flexible bandpass port tube that terminates in a 4.25" ceiling or wall opening, matching standard recessed can-light dimensions. Both round and square magnetic paintable grilles are included, and the optional 4" x 10" Floor Vent Kit allows below-floor cabinet placement with floor register termination.

How does the Klipsch PRO-800SW compare to the PRO-1000SW and the Sonance Sub 8 Round?

The Klipsch PRO-800SW serves a different installation scenario than the PRO-1000SW despite both being Professional Series passive subwoofers. The PRO-1000SW is a stud-bay in-wall design with a 10" Cerametallic driver, reaching deeper to 24Hz at higher output of 200W RMS, optimized for dedicated home theater LFE reproduction. The PRO-800SW is a bandpass in-ceiling and in-floor design with an 8" dual voice coil driver, prioritizing placement versatility and minimal visual footprint over maximum low-frequency extension. The Sonance Sub 8 Round is a comparable in-ceiling bandpass subwoofer with a similar installation philosophy, but the Klipsch PRO-800SW's Cerametallic cone technology, KDA Series DSP amplifier optimization, and Skyhook tool-free installation system provide advantages in both acoustic performance and installation efficiency for professional custom install applications.

Can the Klipsch PRO-800SW be installed in the floor?

Yes, the Klipsch PRO-800SW supports floor installation when paired with the optional 4" x 10" Floor Vent Kit accessory, sold separately. In this configuration, the sealed MDF cabinet is placed in a below-floor cavity, crawlspace, or under-stair enclosure, and the flexible port tube connects via the vent boot kit to a standard 4" x 10" floor register. The register sits flush with the finished floor surface and directs bass output upward into the listening room. This placement option is particularly useful in rooms where ceiling access is not available or where a below-floor installation results in more even bass distribution across the listening area.

What is a Dual Voice Coil woofer and how does it affect system design?

A Dual Voice Coil woofer contains two separate coil windings on the same voice coil former, providing two independent sets of speaker terminals on a single driver. This allows the installer to wire the coils in series to double the impedance, in parallel to halve the impedance, or independently to two separate amplifier channels. In the PRO-800SW, this wiring flexibility supports multi-zone distributed audio systems where impedance optimization across multiple speaker loads is important, or where a single subwoofer needs to be driven from two separate amplifier outputs. It also allows the system designer to match the subwoofer's effective impedance to the output requirements of a specific amplifier without adding external impedance-matching components.

What amplifier do I need for the Klipsch PRO-800SW?

The Klipsch PRO-800SW is a passive subwoofer requiring an external amplifier. Klipsch recommends the KDA Series DSP amplifiers, which include factory-configured equalization and limiter presets custom-engineered specifically for the PRO-800SW's bandpass enclosure and driver, ensuring optimized frequency response and driver protection at high drive levels. Any monoblock or stereo amplifier with stable 8-ohm output capability and adequate continuous power is also compatible, provided a suitable active low-pass crossover is used to restrict the signal to the 38Hz to 125Hz operating range. The dual voice coil design allows impedance configuration at 4 ohms (parallel), 8 ohms (single coil), or 16 ohms (series) to match available amplifier output impedances.

Where can I buy the Klipsch PRO-800SW in Toronto or Canada?

The Klipsch PRO-800SW In-Wall and In-Ceiling Subwoofer is available at Vinyl Sound, an authorized Klipsch dealer in Toronto, Canada. Vinyl Sound carries the complete Klipsch Professional Series architectural audio lineup and can advise on placement options, amplifier selection, Floor Vent Kit compatibility, and system integration for new construction and retrofit whole-home audio or home theater projects across the Toronto area.

What is the difference between the round and square grille included with the PRO-800SW?

Both magnetic grilles included with the Klipsch PRO-800SW cover the same 4.25" port tube termination opening but present different visual profiles in the finished surface. The round grille produces a circular face that matches the diameter of most standard recessed down-can light fixtures, allowing the PRO-800SW port to integrate seamlessly with existing ceiling lighting for a visually cohesive appearance. The square grille produces a rectangular face that suits register-style openings or installations where the square profile matches adjacent architectural elements in the room. Both grilles attach magnetically with no visible hardware and are paintable to match the ceiling or wall surface color.

What is the Skyhook tool-free installation system?

Skyhook is Klipsch's patent-pending tool-free installation mechanism designed specifically for the PRO-800SW's in-ceiling port tube connector. When the port tube is inserted into the ceiling cutout hole, the Skyhook system automatically engages the mounting dog legs against the ceiling surface without requiring a screwdriver, drill, or separate fasteners. This eliminates the need to work with tools in the confined overhead space during installation and significantly reduces the time required to secure the unit. The 90° connector on the port tube also simplifies routing from the concealed cabinet through the ceiling void and into the cutout opening in tight ceiling joist bays.
