Six years in, and my Carbon 7 SE Mk 2 by Fritz Heiler still do the thing that first amazed me about them: they vanish. I sit down, stare right at each cabinet, and still can't place the sound coming from either one. No sound from the left, no sound from the right — just a stage hanging in the room between them.
Everything else holds up too. Bass that's deep and articulate — pitch and texture, not just weight. Midrange that puts people in the room. Extended top end that's detailed without ever tipping into harshness.
I have other speakers too — large, sealed, Beyma AMT plus JBL 15" drivers — and I've been trying a wide range of amps over the years, running them through both speakers each time. Lately it's a DIY Class D that's lighting up the Carbons in a way I didn't expect. Before that, my Dynaco ST-35 also sounded great — and the Carbons still disappeared.
Anyone else own a speaker that still catches them off guard years in?
