The best there is when it comes to subwoofers and this is made to connect with a classic sound reproduction, the REL Classic 99 provides the kind of low end that will lose none of the crispness and accuracy you want to hear from your recordings, especially from your vinyl collection. This is in wonderful condition and only a couple of years old. I have it working with two Harbeth HL-Compact 7ES-3 XD speakers and they work well together, I recommend them highly. This is not a trade deal.
