Preliminary report on the NeoMags. And I'm sorry I don't have before and after clips (I'm not much of a self-recording dude). Mine have aluminum caps. The speakers are very clear - pristine even. At first, I thought they were defective because of buzzing I was getting on certain notes. I finally determined that most of what I'm hearing is originating not in the speaker or the cab but from my guitar strings and fretboard. I prefer low action and get some fret buzz then I dig in hard. The Jensens weren't audibly reproducing this buzz - the NeoMags do. I'll either raise my action in response or just get used to it. The NeoMags are also noticeably less efficient (i.e., less loud) than the Jensens. In fact, they seem way on the low end of the efficiency spectrum to me. This is intrinsically neither good nor bad, it depends on your rig. In my case, it's neutral - the Carvin DCM200L I'm using to drive the NeoMags as way extra clean power to spare. Fascinating the overall NeoMag tone. I'd describe the mids and highs as almost piezo-like. They remind me of Jerry's tone in his later years. Some may like this, others won't. I think these speakers could be well paired with an amplified acoustic guitars or acoustic-electric guitar.
“[P]ersonally I disagree with the general philosophy of ‘genre equals gear’ at anything beyond a cosmetic level. I think the right idea is to find the right amp for you, and then play whatever kind of music you like. The “Jerry Thing” was just Jerry. It wouldn’t have mattered what he used and he used a lot of stuff.” Steve Kimock (The Gear Page 04/08/18)
