Acoustic research 58s speakers. I re foamed woofers using the shim method. The seal on the woofers is good. I removed original crossover, and replaced them with ar91 crossovers. These are the same crossovers, except that the ar91 came with midrange and tweeter switches. I recapped them with Dayton npe caps. Smooth sound and detailed. These are exceptional 3 way speakers, and are essentially a 3 way ar9. These have a superior tweeter to the ar3, ar3a, ar11. No question about it. I installed new grill fabric. The walnut veneer is in good condition. They aren’t new…… But they look nice. 1 midrange driver has a little dimple, but I detect no sound difference. Great lows, great highs, smooth mids that you can now tailor/adjust with a switch. I really like them alot, but 3 pair of ar9’s live here.
