These are a set of 0-3's that I built from Danny's (GR-Research) kit.They are solid MDF construction per Danny's instructions/plans and then to SPICE things up they have SOLID joined Black Walnut baffles and bases.The sides/back are a textured black.I opted for the ports in the front as I think it adds a lot to the look of the speaker.These sound amazing like everyone says that has heard the kit.These have the XBL-2 rear drivers and "No-Res" upgrades.I am looking for $1200 obo.I am not looking to ship these as they are HEAVY.I am located in Charleston, S, Carolina if interested...
