Review: Perfect Tweeters - Used to refurb my 1975 Rectilinear XIa bookshelf speakers. The front panel of the speaker boxes needed some trimming to properly fit these speakers, but it worked out very well. These are awesome tweeters.
Review: Sounds Good - Quality Seems Really Good Too - Just what I needed as a replacement speaker for a 1950 Motorola television set. Works great!

### ⭐⭐⭐⭐⭐ Sounds Good - Quality Seems Really Good Too
*by B***R on May 12, 2025*

Just what I needed as a replacement speaker for a 1950 Motorola television set. Works great!

### ⭐⭐⭐⭐ just 4
*by C***H on December 30, 2013*

only limitation on these is low power rating--15 watts rms, 30 max. hence 2 per the cabinet. sound is okay in homebuilt enclosure, (must tweak): being a cabinetmaker helps as nothing is ever permanent insofar as shape or materials. that's the fun of it. and with the price for both being what it is (way reasonable), disappointment isn't an option. not shielded, so i'd avoid computer applications.
