Frequently asked questions
Can I use just the VRX932LA-1 without a separate subwoofer?
Yes. The VRX932LA-1 is a full-range passive speaker with response down to 75 Hz (±3 dB), making it suitable for venues where low-end extension below that is not critical. The SRX828SP, by contrast, is a subwoofer only and requires main speakers to cover midrange and high frequencies.
Which is better for touring?
Both are professional touring tools, but for different roles. The SRX828SP excels as a dedicated subwoofer in multi-speaker touring rigs. The VRX932LA-1 is lighter, more portable, and works as a standalone main speaker for smaller tours or rental applications, but provides less extreme low-end than a dedicated sub.
What's the key frequency-response difference?
The SRX828SP extends to 29 Hz (–10 dB) and operates only as a subwoofer (35–12 kHz at –3 dB), while the VRX932LA-1 covers 75 Hz–20 kHz (±3 dB) as a complete speaker. The SRX828SP goes deeper; the VRX932LA-1 covers the entire spectrum.
Do I need an amplifier for the VRX932LA-1?
Yes, the VRX932LA-1 is passive and requires an external amplifier (800–3200W depending on configuration). The SRX828SP is self-powered with a built-in 2000W peak amplifier, requiring no separate amp.
