Frequently Asked Questions
It's quite respectable; the Digipro G3 amp keeps things tight, but it's not the absolute fastest—some higher-end models offer even quicker response.
It's genuinely fanless, relying on convection, but prolonged periods at maximum output will still generate noticeable heat, though it's less intrusive than a noisy fan.
Absolutely, the delay function is very useful for aligning the Sub 918 with tops, especially in situations where speaker placement isn't ideal, and the Aurora Net software expands the delay range significantly.
