Infinity Kappa 7.1-II (mid-1990s)
Documentation on the Infinity Kappa 7.1-II is thin. There are no formal reviews, no confirmed production years beyond a single seller's "vintage mid 90s" claim, and no factory spec sheet in the archive. What the record does show is a 3-way tower from Infinity's well-regarded Kappa line. It still has a following among vintage enthusiasts, judging by the active market for replacement parts.
The driver complement is the most concrete thing the archive has. A period listing describes the Kappa 7.1-II as a tall, front-ported tower with a 10" woofer, a 3" dome midrange, and Infinity's Emit-R ribbon tweeter. That is the same basic layout the Kappa series used in the late '80s and '90s. Owners care most about the Emit-R tweeter. Original replacement units (part 902-7206) still trade hands online for around $99.
One caution for anyone shopping for a pair: the sources conflict on woofer size. Some parts suppliers list a 10-inch foam surround for the 7.1-II, while others explicitly warn that "the Kappa 7 uses a 12 inch ring." One repair kit (Springfield Speaker's 2A12-03) is described as fitting Kappa 12-inch woofers and is marketed for both the 7.1 and 7.2i. Given the contradiction, check the woofer diameter on the actual driver before ordering surrounds. Foam surround deterioration is the known weak point of these speakers. The availability of multiple repair kits confirms it's the common failure mode.
Beyond that, the record is quiet. The manual exists (11 pages, English only). The one descriptive line on file says the Kappa 7.1 II is "known for its high-quality sound reproduction," which is thin but consistent with the Kappa family reputation. If you own a pair, the archive would welcome measurements, dates, or any documentation you can share.
