The British Are Here!

I was just gifted four KEF 105/3’s and two 104/2’s. Yes, they need work but I managed to make 2 working boxes from the four. New Tweeters too !

I’ll need reform kits for 2 of the 4 and the 104/2’s. I have the replacement Capacitor’s too from the previous owner.

Instead of using a KEF Cube, I dialed in a nice curve similar to the one measured in Stereophile 30 years ago using MiniDSP.

I’m selling my Subwoofer !


ooh that’s a rather excellent gifting - nice one :slight_smile:

I had to refoam a pair of 105/3s so that I could sell them to a friend. My Garrard 301 TT came in very handy when applying the glue to the cleaned cones.


I watched a Video on YouTube on how to remove and replace the surrounds and donuts on a KEF 104/2 (same process as the 105/3’s). He used a “Lazy Susan” to evenly apply the glue and there’s also an applicator available to smear on top of the donuts from ever rotting again.

Thank you James.

These things are sounding better the more I listen to them. Without proper EQ on the “Cavity Coupled” Bass Drivers, they were smothered in Bass. It was horrible. Once I Bi-Amped and brought the miniDSP curve into the Bass Drivers. My friend has the “Cube” but told me it was noisy.

I’m running a PS Audio S300 @ 4Ω (300WPC) into the 105/3’s Midbass/Uni-Q/Midbass “Pods” (I guess that’s what they are called) and a PS Audio M700’s on the L & R Cavity Coupled Bass Drivers @ 700W each !

Just read up on them here, those miniDSPs seem to be very useful for this kind of adventure, replacing old analogue eq solutions must make quite a difference :slight_smile:

At $100USD a pop (without enclosure, add $20 with) and a 48/24 DAC for processing. These things thing are great. Can be configured as LPF, BPF, and HPF modes as well as Parametric EQ with up to 20db boost at either end.

If I didn’t have the Behringer DEQs, I’d definitely be playing with these :slight_smile:
You get more boost / cut and a much wider range of types of filter algorithms with these too.

Looking forward to following your journey with the KEFs. I had a good friend that purchased the 105/3s while I was in college in early 90s and I was really impressed with them.


Just picked up the 104/2’s today and ordered just the Donuts (surrounds are fine) and protectant goop.


All four 104/2’s Woofer Donuts (Butyl rubber surrounds were fine) and Tweeter Ferrofluid replaced. I added an extra pair of Binding Posts for additional Bi-Amping and bypassed the 8" Coupled Cavity Woofer’s Crossover section. Added a miniDSP that replicates the original KUBE Equalizer but tuned to my room. Not as Bass Intense as the 105/3’s, but better suited for our Apartment Living Room.

Can’t wait to get a real house later this and fire up the four 105/3’s as my main & surround speakers, one 104/2 (the other has a Woofer with a lazy voice coil. Works fine if you don’t push it to hard). The mint working 104/2 will be the Center Channel and I’ll hang four of my 901’s as the Dolby Atmos Channels. My friend gave me a pair of Ohm 2000 series on wall Surround Speakers (perfect for Side Surround Channels).
