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

    The price was incredible for a solid Mackie Product. (stupid deal of the day!) Okay - so they're not powered. I have a bunch of amps not being used so not an issue. I have these sitting on the floor in my band room. They are paired with a small set of Polks for the mids and highs. These are clean, not muddy or thumpy. You can't even tell the bass is coming from them. They are totally unobtrusive in the sound field yet beautiful in enhancing the low end.
