Monitor Audio CL2 S is the compact model in the current Climate Series 3G: a passive, 2-way, IP66-rated wall-mountable loudspeaker engineered for both outdoor and indoor installations. It is packaged and sold as a manufacturer-defined pair, with Black and White finish variants under one product family.
Each speaker combines a 4-inch C-CAM RST II bass-mid driver, a 25 mm C-CAM black-dome tweeter and an Auxiliary Bass Radiator (ABR) in a sealed weather-resistant cabinet. Monitor Audio publishes a 56 Hz–30 kHz on-wall response (-6 dB), 84 dB installed sensitivity, 108 dB maximum peak SPL and 70 W continuous power handling.

IP66 — preserve the actual rating
Climate Series 3G is rated IP66. Monitor Audio describes this as full protection against dust and protection against powerful water jets, using a sealed cabinet engineered and tested for demanding environmental exposure.
That rating should not be simplified into a generic “waterproof” claim. IP66 is the verified ingress-protection classification; it does not mean the speaker is designed for submersion. Installation location, cable routing, mounting surface and applicable electrical / building requirements still matter.
Auxiliary Bass Radiator instead of a conventional port
CL2 S uses an Auxiliary Bass Radiator (ABR) rather than a conventional bass-reflex port. The passive radiator moves in response to the pressure generated inside the cabinet by the active bass-mid driver, extending low-frequency output without requiring an open port through the weather-resistant enclosure.
This architecture is especially relevant outdoors, where low frequencies do not benefit from the same room-boundary reinforcement available in an enclosed interior space.
Quik-Link-inspired mounting system
The Climate Series 3G mounting system is designed around a die-cast Quik-Link-inspired bracket. Monitor Audio allows the bracket to be pre-fitted to the wall in a vertical or horizontal plane, with speaker cable terminated into connectors housed within the bracket itself.
Protective rubber seals help keep those connections sheltered from environmental ingress. Once fitted, the speaker can rotate on its axis to direct sound toward the required listening area. This separates much of the cable termination and bracket work from the final speaker attachment, which is particularly useful in pre-wire and staged-installation workflows.
Amplifier matching
CL2 S is rated at 6 ohms nominal and reaches a published minimum impedance of 4.9 ohms across 20 Hz–20 kHz. Continuous speaker power handling is 70 W (CTA 426-B).
Monitor Audio separately publishes 150 W recommended amplifier power, specified as RMS with a music signal. These are different specifications: the 70 W figure is continuous loudspeaker handling under its stated test standard, while the 150 W figure is the manufacturer's published amplifier recommendation. They should not be collapsed into one generic “wattage” value.

CL2 S or CL2 M?
CL2 S is the more compact Climate Series 3G chassis. CL2 M is the larger companion model with a 6-inch C-CAM RST II bass-mid driver and larger enclosure. The correct choice should be based on required output / low-frequency capability, physical scale and mounting location rather than treating the larger model as automatically appropriate for every outdoor space.
Finish, SKU and GTIN identification
| Finish | SKU / MPN | GTIN-13 |
|---|---|---|
| Black | CL2SB | 5060565774919 |
| White | CL2SW | 5060565774902 |
Important purchase detail: CL2 S is packaged and sold by Monitor Audio as a pair. The pair is the manufacturer's normal sell unit; it is not a retailer-created multipack.
Warranty
Monitor Audio's current Climate Series 3G product page supports a 5-year warranty. This current warranty supersedes older internal material that listed a lifetime term for CL2 S.
