Klipsch R-40PM is a model that represents an active wireless version of Klipsch R-40M passive speakers, equipped with built-in digital amplifiers with 50W per channel, a Bluetooth module, and wide connectivity options. The speakers feature sturdy, acoustically inert cabinets designed in a minimalist style. The cabinets are made of MDF and finished with scratch-resistant vinyl film with a wood texture, and they are protected by low-profile grilles held in place by magnetic fasteners. The 20mm thick panels make the construction rigid and durable. The cabinets are adorned with vinyl film in a wood texture finish, resistant to mechanical damage. The classic design and high-quality construction of the speakers make them blend well in a home interior. The rear panel of the speaker features an integrated circular port for the rear-firing woofer.

The main feature of Klipsch R-40PM, like other speakers from this American company, is the use of a horn-loaded tweeter. The model includes an updated patented Tractrix horn with square geometry. It has a smooth curve on the inner surfaces to align the directivity pattern of the installed tweeter. The tweeter features a 25mm aluminum dome and a Kapton suspension that ensures linear diaphragm movement (LTS technology). This design allows for a good linearity of the speaker's characteristics at high frequencies, creating detailed and airy sound.

The low frequencies in Klipsch R-40PM are reproduced by a 4-inch woofer. It utilizes the same design solutions as the low-frequency drivers in Klipsch's premium Reference Premiere series speakers. The woofer's diaphragm is made of crystalline polymer, manufactured using high-temperature pressing, and has a monolithic surface. The external copper coating not only gives the speakers a recognizable look but also helps dampen resonances. The woofer is loaded on a rear-firing port, with the outlet located on the back panel of the cabinet.

The pair of Klipsch R-40PM speakers includes a master speaker (active monitor) and a slave speaker (passive monitor), which connects to the master speaker using screw terminals and the included cable. The active monitor houses digital amplifiers with low noise levels and a phono preamp, with a volume control knob on its rear panel combined with an input selector and all necessary connections. There are a pair of RCA jacks that can function as a line-level input or as Phono sockets for connecting a turntable (selected by a separate toggle switch). Other inputs include: Aux (3.5mm) for a player or smartphone, a USB port for connection to a computer (PCM up to 24 bit/96 kHz), and an optical connector. To enhance the bass foundation, Klipsch R-40PM features a Sub Out for connecting an active subwoofer.

Klipsch R-40PM is equipped with a Bluetooth receiver, allowing audio streaming from smartphones, tablets, and other Bluetooth devices. The speaker also includes a dynamic EQ for boosting bass response, particularly effective at low volume levels. The pair of Klipsch R-40PM speakers can be a great alternative to multi-component audio systems, as it features built-in amplification that synergizes well with the speaker drivers, and includes all necessary connection ports. A small remote control is also included in the package.
