They certainly look "unhealthy".

But check out the pictures here:

The deformation on the surround is almost visible in multip ...

Thanks for the KUBE curves. I have mk1.

I had that issue with bright treble before adding the KUBE. The parametric equalizer had been set for -3dB beyond 5kHz and that tamed it enough. Thought it w ...

If the KUBE is extending it's slopes to the midrange, it can be set before the bass and midrange power amps and take care of both ranges, leaving the treble alone to feed directly from the preamp to t ...

So you are saying, tri-amp, in effect, by splitting the crossover and drive each section alone, and avoid the active crossover stage.

That's an idea, however, if IIRC, I've read that the R107 main ...

I just added the KUBE to the amplification chain (removing the quick and dirty solution of the parametric equalizer I used) and it makes a huge difference. But it really strains the amplifier (2x110W/ ...

You can go the good quality heavy wood with braces and bitumen sheet damping. I have done that for a 200lt enclosure with 20mm high quality plywood, hardwood braces (3 across the height) and 9mm bitum ...

Obviously, if you have the sub, use it.

Regarding using the KUBE or not, there are those who find the op amps in most KUBEs offending and swap them for better ones or prefer to listen without the ...

I don't have a pair of 104/2 but do have a functional pair of 107. Similar bandpass design.

Although it's not the same speaker design, the bandpass low frequency section is able to give a real hard ...

Yes, seems to be gone.
I contacted KEF in the UK to let them know that we hope it's just an update glitch.

Hope it comes up again soon.

Until then,

B200 SP1054 + T27 with a passive BD139 give you the essentials for a KEF Calinda. Although the Calinda is a smaller box compared to the Cantata box.

DN18 is the proper crossover for the Corelli, wh ...

According to specs (see http://www.kef.com/html/en/explore/about_kef/museum/1970s/Reference_Series103/index.html) you can use an amplifier between 25-100WRMS.

The A900MkII, rated at 90WRMS @8Ohms, ...

What's wrong with them? Perhaps they can be repaired for a fraction of the cost.

Don't know where you are located but check them out:

How does a tweeter with dried up ferrofluid sound? Does it sound bright or dull?

My KEF 107/1 tweeters appear to sound a bit bright. I am not sure if the first series had ferrofluid or not. Wonder ...

My 105.1 didn't need too much power before the couch I was sitting on started to vibrate in sync. The room is the key. In a small room you eventually have speaker/listener positioning c ...
