Compact, Clear, and Built to Perform
The UNOBASS NP40 delivers 40W of rich sound, wide frequency response, and up to 15 hours of battery life. Use AUX-In for zero-latency playback — perfect for real-time playing with Neoharp. Waterproof and portable, it’s ideal for everyday use at home, in the studio, or outside.
For the best experience with the Neoharp, we recommend using the Unobass speaker, as it offers minimal latency, ensuring high-quality, real-time sound reproduction. For real-time performance with Neoharp or other instruments, use the AUX-In for zero-latency playback. This distinguishes it from many other speakers we have tested, which can introduce a noticeable delay.
