km5’s Sp1 speaker matches the Cp1 CD player—and works on its own

km5 has announced two same-size companions for its existing wall-mountable Cp1 CD player: the Sp1 Bluetooth speaker and Mp1 wireless mixer. According to AV Watch’s report from the October 21, 2026 announcement, Sp1 can also play radio or saved music without either Cp1 or a phone.

Radio and saved music, without reaching for a phone

Alongside Bluetooth and an AUX input, Sp1 includes a wide-FM tuner with a telescopic antenna and a microSD slot for music playback. It supports MP3, FLAC, WMA, WAV, AAC and APE files, and can record radio to microSD.

The speaker weighs 490 g, with its built-in battery rated for 12 hours of playback. Those standalone sources make it usable even if you have no plans to add a CD player.

One Sp1 is mono; two bring stereo to Cp1

Sp1 contains two 45 mm full-range drivers and two passive radiators, but a single unit plays in mono. For stereo listening with Cp1, you need two Sp1 speakers paired with the player.

Sp1 can hang on a wall alongside Cp1, which is sold separately. Mp1 is not required for that stereo setup, so there is no need to buy the whole range just to listen.

Mp1 lets you mix two Bluetooth sources

The optional Mp1 is designed for casual music mixing, taking two Bluetooth inputs from sources such as Cp1 and a smartphone. It sends the mixed audio to wireless speakers or wired headphones connected to its headphone output. It can also transmit Bluetooth stereo to two Sp1 speakers.

Line input and output offer a wired option, while a three-band EQ, filter and internal-memory loop function let you adjust the sound and repeat a chosen passage. Mp1 weighs 350 g and runs for up to six hours on its built-in battery.

Both new products are planned in black and white. Neither is on sale yet: exact release dates remain unspecified, and prices will be announced later.
