km5 introduces Sp1 speaker alongside Mp1 wireless mixer

km5 has introduced the Sp1 portable wireless speaker alongside the Mp1 wireless mixer. The Instant Sound Audio Sp1 uses two 45 mm full-range drivers. Preorders for both products are scheduled to open through km5's official store on 16 November 2026, with shipping planned to begin from February 2027.

The Sp1 combines its drivers with two passive radiators and incorporates a digital power-amplifier IC. Its built-in battery is rated for approximately 12 hours of continuous playback. Two Sp1 speakers can be linked together for stereo playback. The speaker has a slim, compact enclosure that supports wall mounting.

Bluetooth audio playback is supported alongside an integrated FM radio and playback from microSD cards. The Sp1 can also record radio programmes to microSD, allowing the card to serve as both a playback source and a recording medium.

The Instant Wireless Mixer Mp1 is a two-channel model that accepts two Bluetooth audio sources for mixing. It can transmit the resulting mixed audio to a Bluetooth speaker. Line input and output connections provide wired audio connections alongside its wireless facilities.

The Mp1 includes three-band EQ and a filter function for adjusting the audio being mixed. A loop function allows a selected section of music to be repeated. Power comes from a built-in lithium-ion battery, with a rated continuous runtime of approximately six hours.
