Frequently asked questions

Do I need a separate amplifier for either product?

Yes, the CBT 1000E-WH is passive and requires an external amplifier when paired with the CBT 1000. The SRX915M has built-in amplification and integrated DSP, so no external amp is needed.

Which is better for a touring band that needs mobility?

The SRX915M is self-contained and portable, making it ideal for touring without extra gear. The CBT 1000E-WH is designed as part of a larger column system and is best for fixed or semi-permanent installations.

What is the low-frequency extension of each?

The CBT 1000E-WH extends the CBT 1000 system down to 38 Hz when stacked together. The SRX915M reaches 50 Hz on its own, or integrates with SRX900 subwoofers for additional low-end control.

Can the SRX915M work as a monitor speaker?

Yes, the SRX915M's 45-degree monitor angle and rotatable waveguide make it suitable for both front-of-house and stage monitor applications. The CBT 1000E-WH is strictly a bass-extension module for the CBT 1000 column and cannot function independently.
