You don’t buy KEF 104/2s to impress your friends. You buy them because you want to hear “Aja” the way it was meant to be heard—without spending the rent money. These speakers were born in 1982, right when KEF figured out how to cram that BBC-licensed smoothness into something that could actually play a bass line without crying.
The 104/2 was KEF’s answer to the LS3/5a’s limitations. Same midrange approach—using a highly controlled polymer cone—but with real extension. The midrange driver is a 160mm (6.5-inch) Bextrene cone with a fixed phase plug, surrounded by a stiff rubber surround that won’t rot like the foam on cheaper stuff. Below that, two 200mm drivers work in a coupled-cavity arrangement: one active, one passive (auxiliary bass radiator). The result is tight, tuneful bass down to about 45Hz—no thud, just pitch.
What makes them special is what they don’t do. They don’t shout, don’t sizzle, don’t draw attention to themselves. Walk around the room and the image stays locked. Transients are crisp but never harsh. Voices sound like they’re in the room, not through a tin can. That’s the BBC influence: designed for critical listening, not showroom theatrics.
The real trick is how small they remain. Standmount size—about 20x14x13 inches—but with floorstander extension. You can put them on a decent stand and forget they’re there. Except for the grilles, which are these weird fiberglass panels that some people love and others rip off. I say leave them on.
Here’s the honest caveat: the foam surrounds on the passive radiators will eventually crumble. It’s a 45-year-old speaker. New foam kits are cheap and the repair is straightforward—pop the driver, clean the old surround, glue the new one. Also the crossover caps could use refreshing. But do that and you’ve got a speaker that competes with $2,000 modern stuff. For $400? That’s not a deal, that’s a mercy.
They came in a few finishes: walnut veneer (most common), rosewood, and black ash. Walnut is the one. They’re not rare—thousands were made—but the condition varies. Find a pair with original boxes and you’ve hit the lottery.
If you want to hear what flat-phase, BBC-voiced coherence sounds like without selling a kidney, the 104/2 is your speaker. Just be ready to refoam.
