Acoustic Research AR 25BXI (1980s)
The AR 25BXI is an Acoustic Research model that survives mostly through the parts trade rather than the historical record. It's tagged as a 1980s speaker. The most solid fact we have is that it uses an 8-inch woofer in an acoustic suspension enclosure, the sealed-box design AR pioneered. A replacement woofer driver is readily available, listed at $31.00. Foam surround repair kits are sold by several suppliers, which points to the usual age problem of decaying foam surrounds. Recommended amplifier power is documented at 10-100 watts.
The "BXI" designation appears to denote an enhanced variant of the earlier AR-25, with upgraded crossover components and refined driver integration for improved frequency response and soundstage. Beyond that, the record gets thin. No production years beyond "1980s," no original price, no frequency response, impedance, sensitivity, or dimensions are documented. One listing calls the 25BXI a "digital crossover monitor" with "Arista's advanced digital protocol analysis technology." That is almost certainly a listing error, since it makes no sense for a 1980s analog speaker, so we're omitting it.
