Very loud, tight mid bass. I have 3 of these wired in 4 ohm mono and connected to a Cadence a7000 which puts out 900 watts mono@4 ohms. It is enough to make you sick and feel very faint. LOUD and terribly loud. I take motrin.

not enough low, low bass

These subs are well worth the money, but I can't get them to go as low as I want them to. They need more air I think.
