Infinity Qb (1978-1983). Very good condition. Famous EMIT ribbon tweeters. Sealed enclosures. Midrange control (and fuse) in rear. Very balanced, realistic, nice loud detailed bass. All original drivers (and rubber surrounds) in excellent condition. Cabinets are cosmetically a 9/10 (no scratches, one minor ding - speaker on right in photo, on top, left edge). Sturdy cabinets w/veneer. Easy to power. I don't have grills but someone just contacted me who has a pr. (for free). Asking $220. Contact me for shipping quote. I accept Paypal. Might consider other methods.
