#162 PMC twenty5.21 Discontinued Estimated eBay
Older model: the PMC twenty.21 (ranked lower, rated 1.3/5).
Pros: The successor to the PMC twenty.21 in the same cabinet, with a new woven cone mid/bass and Laminair vent fins that cut turbulence in the transmission line. The Ear found it even-handed and revealing with very quiet backgrounds.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. The Ear found dynamics limited on loud music and bass that needs near-wall placement, and it has been replaced by the twenty5.21i. Discontinued.
