Acoustic  Research  AR28B  
Compact sealed-box speaker from famous USA manufacturer, Acoustic Research. The AR28B model woofer has a different cone and dustcap from our previously offered AR38s model, and also a soft dome tweeter rather than the paper cone/dome of the AR38s.

The crossover is similarly minimal, just a single capacitor, which in this pair has been upgraded to a new polypropylene type. Both woofers have new high-compliance foam surrounds.

Cabinets are generally good, and they come with the original grilles, NRPavs may replace the cloth in due course.

Tight and punchy sound, designed to work best up against a wall. These 2-way speakers will function well as main speakers, but in combination with either AR94, or in future, AR98LS model fronts, they would help make up an excellent 70's style home theatre set.
