Frequently Asked Questions
RCF refined the driver response in the MK3, resulting in tighter, more controlled low frequencies and improved transient response without sacrificing output.
The limiter is transparent; it subtly reduces headroom to prevent clipping without audible distortion, protecting the amplifier and driver.
Two-way systems with 10” or 12” woofers in the 500-800W range will complement the SUB 708-AS MK3 nicely, ensuring a balanced frequency response.
