Up for sale is a great sounding pair of speakers from Infinity's '90s Reference line. The Ref Four is a three-way design with a 8" woofer and 5" mid featuring Infinity's IMG cone, polypropylene injected with graphite fibers for a cone that's lightweight and extremely rigid. The tweeter is Infinity's EMIT-R ribbon tweeter using a radial pattern.

Both woofers and mids have just been refoamed with new surrounds.

I did two mods to these back in the 90's. First the internal wiring was upgraded using Esoteric Audio OFC speaker wire. Second the front panel behind the grills was covered with damping material to reduce unwanted reflections from the front panel and improve imaging.

The cabinets are in excellent shape, the grills are in great shape as well but the right one does have small hole in the cloth. Still overall, very presentable.
