PSB CS605 6.5" 2-Way In-Ceiling Flush Mount Speaker at Vinyl Sound Toronto Canada

The CS605 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. Positioned as the most accessible model in the PSB CustomSound CS600 architectural series, the CS605 brings over 45 years of PSB acoustic research into a 6.5" ceiling format suited to whole-home background music, multi-room audio installations, and Dolby Atmos height channel builds where multiple speakers are required across a large space. It features a 6.5" carbon-filled polypropylene cone woofer with foam surround, a proprietary 3/4" treated textile soft dome tweeter, and a first-order high-pass crossover network. The CS605 shares PSB's consistent sonic signature across the CustomSound series and integrates naturally alongside CS610, CS630, or CS650 speakers deployed in the same multi-room installation.

PSB Signature Sound at an Accessible Entry Point

The CS605 is built around PSB's 6.5" (165mm) woofer, using a carbon-filled polypropylene cone on a stamped steel basket with a foam surround. This construction delivers the warm, wide, and even dispersion characteristic that has defined PSB's architectural speaker lineup across its full price range. The 3/4" (19mm) treated textile soft dome tweeter is ferrofluid-cooled for thermal stability under sustained use and concentrically mounted for consistent high-frequency dispersion across the listening room. A first-order high-pass crossover network keeps the circuit design simple and the overall speaker weight low at 4.6 lb (2.1 kg), a practical advantage when installing multiple units across a large home. The CS605's sonic character is deliberately matched to its CS600 series siblings, ensuring consistent tonal balance whether the CS605 is used as a standalone speaker in a background music zone or as part of a larger PSB-based system where CS610 or CS650 speakers handle primary listening areas.

Easy Installation and a Clean, Low-Profile Ceiling Finish

The CS605 is designed for fast, repeatable installation across multi-room projects. The heavy-duty dogleg cam-lock mounting system secures the speaker to finished ceilings without special tools, and the speaker can be removed and repositioned without damage to the ceiling cutout. The provided round magnetic frameless grille attaches without visible hardware and is paintable to match any ceiling finish, giving the CS605 a virtually invisible installed profile. Spring-post terminals accept bare wire, pin connectors, and single banana plugs, compatible with standard in-wall speaker cable and multi-zone amplifier outputs. A cutting template is included in the box, and optional pre-construction brackets and a backcan enclosure are available separately for new construction rough-in applications. The CS605 shares its 8 3/8" (212mm) cutout diameter with the CS610, CS630, and CS650, providing a future upgrade path to any of those models without additional ceiling penetrations.

Frequently Asked Questions

What is the PSB CS605?

The PSB CS605 is an entry-level 2-way in-ceiling flush mount speaker featuring a 6.5" carbon-filled polypropylene woofer, a 3/4" treated textile soft dome ferrofluid-cooled tweeter, and a first-order high-pass crossover. It is the most accessible model in the PSB CustomSound CS600 architectural series, designed for whole-home audio, multi-room background music, and Dolby Atmos height channel installations. It is sold individually as a single unit and includes a round magnetic frameless grille only.

What is the difference between the PSB CS605 and the PSB CS610?

The PSB CS610 is the next step up in the CS600 series, while the CS605 is the entry-level option. Both share the same 8 3/8" ceiling cutout, allowing a direct drop-in upgrade from the CS605 to the CS610 without additional ceiling work. The CS610 features an aluminium dome tweeter with a waveguide and aimable ball-joint pivot mount, a 2100Hz LR4 Linkwitz-Riley fourth-order crossover, a single tweeter level switch, and gold-plated spring-loaded binding posts. The CS605 uses a treated textile dome tweeter with a simpler first-order crossover and no tweeter level adjustment or aimable pivot. For primary stereo listening rooms or home theatre applications, the CS610 is the stronger choice; the CS605 is best suited to secondary rooms, hallways, and multi-zone whole-home audio builds where value and quantity matter most.

How does the PSB CS605 compare to the Polk Audio RC60i or Klipsch CDT-3650-C II?

The PSB CS605, Polk Audio RC60i, and Klipsch CDT-3650-C II are all 6.5" entry-level in-ceiling speakers targeting whole-home audio and home theatre surround use. The Polk RC60i uses a 1" silk dome tweeter and is widely used in budget distributed audio installations, but its crossover and driver tuning are not benchmarked against a national acoustic research facility. The Klipsch CDT-3650-C II uses a tractrix horn tweeter for high efficiency suited to cinema dynamics. The CS605 is tuned to share PSB's consistent sonic signature across the CustomSound series, which means it integrates naturally in multi-room systems where CS610 or CS650 speakers handle primary zones. For Toronto homeowners building a PSB-based whole-home audio system, the CS605 is the natural starting point in the CS600 family.

Can the PSB CS605 be used for Dolby Atmos height channels?

Yes, the CS605 is well suited for Dolby Atmos and DTS:X overhead height channels in a home theatre system. Its 6.5" woofer provides adequate dynamic output for cinematic overhead effects in rooms of standard ceiling height, and the treated textile dome tweeter delivers smooth, even high-frequency dispersion across the listening area. For primary left, center, and right channels in a demanding home theatre, the CS610 or CS650 are the more refined choices due to their LR4 crossovers and higher-specification tweeter designs.

Does the PSB CS605 come with a square grille?

No, the CS605 is supplied with a round magnetic frameless grille only. PSB's own data sheet confirms that within the CustomSound series, only the CS605 and CS805 are supplied with round grilles only; all other models in the CS600 and CS800 series include both round and square grilles. If a square grille profile is required, the CS610 is the next step up and includes both shapes.

What amplifier or receiver works with the PSB CS605?

The CS605 presents a nominal 6-ohm impedance load and is compatible with standard home theatre receivers, stereo integrated amplifiers, and multi-zone matrix amplifiers used in whole-home audio installations. Brands such as NAD Electronics, Bluesound, Yamaha, Denon, and Anthem are all suitable pairings. The CS605's 85dB anechoic sensitivity (87dB in-room) means it reaches comfortable listening levels with modest amplifier power, making it practical for installations requiring many zones from a single multi-channel amplifier.

Where can I buy the PSB CS605 in Toronto or Canada?

The PSB CS605 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 for whole-home audio builds, amplifier pairing, and professional installation services for residential projects throughout the Greater Toronto Area and across Canada.

Is the PSB CS605 sold as a pair or individually?

The CS605 is sold as an individual unit (each). For stereo in-ceiling pairs, two units are required. For multi-zone or Dolby Atmos installations requiring four or more ceiling speakers, the appropriate quantity should be added to the cart. All units include a round magnetic frameless paintable grille and a cutting template.
