Independent shopping perspective
The Korena take
The TS408 is an active 8-inch PA speaker that combines 2,000W power with onboard mixing, Bluetooth playback, DSP control, and app access. Its three-channel mixer gives separate level control for connected sources and Bluetooth audio, while the two balanced combo inputs and XLR link output cover direct connections and speaker chaining. Use it upright on a 36 mm pole, as a wedge monitor, or in an installed flown or suspended position. True Wireless Stereo pairs two TS408 speakers for a wireless stereo system.
Strong match
Who this is for
- Small PA setups needing microphone, instrument, and Bluetooth sources controlled from one powered speaker.
- Floor-monitor use, pole-mounted reinforcement, or installations using the speaker’s specified suspension and flown options.
- Wireless stereo playback when using two TS408 loudspeakers with True Wireless Stereo.
Consider the trade-offs
When to look elsewhere
- A single-speaker setup when you specifically need the two-speaker True Wireless Stereo function.
