Deep bass sound and surprisingly good mids and clarity from this ported 18 inch bass cabinet. And it's seriously road-ready. Heavy plywood cabinet with metal bracing at all corners and large casters. Steel grille over the speaker and port. Metal and plywood front cover attaches over metal grille so the whole thing can be sealed up for transport. Solid handles on each side for lifting. Single 8 ohm input rated for 400 watts. I've been playing a Trace Eliot 200W pre-amp through it, but I haven't played out any at all in recent years, and this cab is too much for my needs (and too large to carry up and down stairs alone). I bought a great sounding, lighter Epifani 15", and need to sell this one. Located in Chesapeake, Virginia (near Norfolk / Virginia Beach).
