Frequently asked questions
Can I use the 4739 on its own?
No. The 4739 is a bass section only and requires matching mid and high-frequency tops (sold separately) to function as a complete loudspeaker. The AC566-WH is a complete 2-way system ready to use immediately.
Which is better for live sound gigs?
The AC566-WH works standalone for most gigs and is easier to transport. The 4739 is designed for large touring and cinema installations where extended bass and very high output are critical and you pair it with mid/high tops.
How do the frequency ranges compare?
The AC566-WH covers 75 Hz–18 kHz as a full-range unit. The 4739 extends lower (30 Hz) but only handles bass; you must add a separate mid/high section to cover the rest of the spectrum.
Which is more power-hungry?
The 4739 handles 500–800 W and has higher sensitivity (104 dB), making it efficient for large venues. The AC566-WH is rated at 122 dB SPL max with 98 dB sensitivity, suitable for smaller to mid-size applications.
