Model TW-410t. I don't think these are being made anymore. 400 watts, 8 ohms, very good condition. I don't know how old it is but would guess about 5 years. Covered with carpet, has castors mounted on bottom, nice big handles, metal grill. Has an variable attenuator for the tweeter. Rear ported. Very similar in sound to a SWR Goliath II that I owned a few years ago but I would say the tubeworks has smoother highs - maybe a better tweeter or crossover. Great cabinet for slap but pretty versatile all around. I'll let it go for $250 plus shipping from 53704. Prefer local sale.
