    Comments about Mackie iP-18S 18" Passive Subwoofer:

    These subs are great. Got a couple to my existing powered arm 1850 subs. These things have great lunch and have great detailed bass that you can't really find on lower end models. These speakers have no handles and are ment for permanent install hence the no handles and pole sockets for speakers. They do have fly points so that's a plus. These subs look very sleek and professional. The only downfall though is that they should have used a extra thick coating. I can easily see if anyone decides to dance on these subs that scratches will easily show. My verdict, very happy with my purchase.
