Frequently asked questions
Can I use the CBT 1000E standalone without a CBT 1000?
No. The CBT 1000E is explicitly designed as an extension module paired only with the CBT 1000 column speaker via its included coupler plate and requires external amplification.
Does the SRX915M need additional amplification or subwoofers?
No. The SRX915M includes built-in amplification and DSP, so it works standalone out of the box. An optional 80 Hz highpass preset works with SRX900 subwoofers if you want additional low-end control, but it is not required.
Which system is more portable for gigging?
The SRX915M is more portable and self-contained—it requires only a power connection and audio input. The CBT 1000E requires an external amplifier, additional cabling, and must be paired with a CBT 1000, making it less practical for quick single-unit deployment.
How do the low-frequency capabilities compare?
The CBT 1000E extends below 38 Hz with six drivers and higher SPL output (124–130 dB) in the bass region, while the SRX915M offers 50 Hz low-frequency extension from a single 15-inch driver. The CBT 1000E provides deeper, more powerful bass; the SRX915M provides adequate bass for general live-sound applications.
