PSB CS805 8" 2-Way In-Ceiling Flush Mount Speaker at Vinyl Sound Toronto Canada

The CS805 is an entry-level 2-way in-ceiling flush mount speaker from PSB Speakers (Lenbrook Industries, Ontario, Canada), available at Vinyl Sound in Toronto, Canada. The most accessible model in the PSB CustomSound CS800 architectural series, the CS805 delivers PSB's signature hi-fi sound in an 8" ceiling format at a price point suited to multi-room audio installations, whole-home background music systems, and home theatre surround builds requiring multiple speakers across a large space. It features an 8" carbon-filled polypropylene cone woofer with foam surround, a proprietary 1" treated textile dome ferrofluid-cooled tweeter, and a verified frequency response of 48Hz to 20,000Hz (±3dB). The CS805 shares the same 9 3/4" (245mm) ceiling cutout as the CS810 and CS850, allowing future upgrades to either premium model without additional ceiling work.

PSB Signature Sound in an 8" Entry-Level Format

The CS805 is built around an 8" (203mm) polypropylene cone woofer with a stamped steel basket and foam surround, a driver combination that provides broad bass extension down to 48Hz and sufficient dynamic output for large room coverage in whole-home audio installations. The proprietary 1" (25mm) treated textile dome tweeter is ferrofluid-cooled for thermal stability, providing clear, smooth high-frequency reproduction across the full 48Hz to 20,000Hz bandwidth. Unlike soft dome tweeter designs found in some competing entry-level in-ceiling speakers, PSB's textile dome is tuned to share the sonic character of the CS800 series as a whole, ensuring that the CS805 blends naturally with CS810 or CS850 speakers installed elsewhere in the same system. A first-order high-pass crossover network manages the transition between woofer and tweeter, keeping the circuit design simple and the overall speaker weight low at 3.25 lb (1.47 kg) per unit — an advantage when deploying multiple speakers across a large installation.

Simple Installation and Clean Ceiling Aesthetics

The CS805 is designed for fast, reliable installation in finished ceilings. The heavy-duty dogleg cam-lock mounting system secures the speaker to the ceiling without special tools, and the speaker can be removed and re-installed without damage to the ceiling cutout. The provided round magnetic frameless grille attaches magnetically with no visible hardware and is paintable to match any ceiling color, allowing the CS805 to disappear into the room. Spring-post terminals accept bare wire, pin connectors, and single banana plugs, compatible with standard in-wall speaker cable. A cutting template is included in the box. Pre-construction brackets and a backcan enclosure are available separately for new construction applications. The CS805 shares its 9 3/4" cutout diameter with the CS810 and CS850, providing a clear upgrade path to either model in future renovations without requiring new ceiling penetrations.

Frequently Asked Questions

What is the PSB CS805?

The PSB CS805 is an entry-level 2-way in-ceiling flush mount speaker featuring an 8" carbon-filled polypropylene woofer, a 1" treated textile dome ferrofluid-cooled tweeter, and a frequency response of 48Hz to 20,000Hz (±3dB). It is the most accessible model in the PSB CustomSound CS800 architectural series and is sold individually as a single unit. The CS805 includes a round magnetic frameless grille only.

What is the difference between the PSB CS805 and the PSB CS810?

The PSB CS810 is the mid-tier model in the CS800 series, while the CS805 is the entry-level option. Both share the same 9 3/4" ceiling cutout, making them directly interchangeable in an existing ceiling opening. The CS810 uses a 1" titanium dome ferrofluid-cooled tweeter with a precision waveguide and aimable ball-joint pivot, a 3100Hz LR4 crossover network, and a dual-position tweeter level switch for post-installation room tuning. The CS805 uses a 1" treated textile dome tweeter with a simpler first-order crossover and no tweeter level adjustment or aimable pivot. The CS805 is the right choice for multi-zone whole-home audio builds or secondary rooms where value and installation speed are priorities; the CS810 suits primary listening rooms and home theatre applications where tonal accuracy and imaging matter more.

How does the PSB CS805 compare to the Polk Audio RC80i or Klipsch CDT-5800-C II?

The PSB CS805, Polk Audio RC80i, and Klipsch CDT-5800-C II are all 8" in-ceiling speakers positioned for whole-home audio and home theatre use. The Polk RC80i uses a 1" silk dome tweeter and is designed as a budget multi-room speaker with a simple crossover, similar in positioning to the CS805. The Klipsch CDT-5800-C II uses a tractrix horn for high efficiency, which delivers strong cinema-style output but can have a brighter character in reflective rooms. The CS805 differentiates through PSB's NRC-informed driver tuning and consistent sonic signature with the broader CustomSound series, ensuring it integrates naturally in systems where CS810 or CS850 speakers handle primary zones. For Toronto homeowners building a multi-room PSB system, the CS805 is the logical entry point.

Can the PSB CS805 be used for Dolby Atmos height channels or home theatre surround?

Yes, the CS805 is suitable for Dolby Atmos overhead height channels and home theatre surround use. Its 8" woofer delivers sufficient bass output and dynamic range for cinematic overhead effects in standard ceiling heights, and its frequency response to 48Hz ensures adequate low-frequency support for height channel content. For primary left, center, and right channels in a demanding home theatre, the CS810 or CS850 are the stronger choices due to their more refined driver and crossover specifications.

Does the PSB CS805 come with a square grille?

No, the CS805 is supplied with a round magnetic frameless grille only. This distinguishes it from the CS810 and CS850, which include both round and square grilles. If a square grille profile is required for aesthetic reasons, the CS810 or CS850 would be the appropriate choice in the CS800 series.

What amplifier power is recommended for the PSB CS805?

The CS805 accepts between 10 and 100 watts per channel into its 6-ohm nominal impedance (minimum 4 ohms). Its 85dB anechoic sensitivity (87dB in-room) makes it easy to drive with standard home theatre receivers and multi-room amplifiers. The CS805 is compatible with distributed audio amplifiers and receivers from brands including NAD Electronics, Bluesound, Denon, Yamaha, and Anthem, as well as dedicated multi-zone matrix amplifiers used in whole-home audio installations.

Where can I buy the PSB CS805 in Toronto or Canada?

The PSB CS805 is available at Vinyl Sound, an authorized PSB dealer in Toronto, Canada. Vinyl Sound carries the full PSB CustomSound architectural speaker lineup and can assist with multi-room audio system planning, speaker quantity calculations, amplifier pairing, and professional installation services for residential projects throughout the Greater Toronto Area and across Canada.

Is the PSB CS805 sold as a pair or individually?

The CS805 is sold as an individual unit (each). For stereo in-ceiling systems, two units are required. For whole-home audio or multi-zone installations requiring multiple ceiling speakers, the appropriate quantity should be added to the cart. All units include a round magnetic frameless paintable grille.
