Without measurements -for now- I would only opt for the above, improve some components, increase the rigidity of the box, speaker connectors, wires ...

More measures are missing, such as only the tweeter, the impedance and phase graph and the CSD. And, most importantly, the frequency response at the listening point in your room. If it is in the near field everything is easier.

It is pretty good. With a slight answer in "V" that rockers -JBL lovers- like but that I would soften.

I would first try to flatten the answer without abusing, focusing on the tweeter. With a minimum phase PEQ in a good software player.

First brute attack with an only filter at 8 kHz. -3 dB and Q=0.8 (proportional aka RBJ filter).

Danny has created a new crossover for my KEF 102.2's

These were made in 1995. I have owned them for the last 15 years.

They do sound much better that they ever have.



Front of the speaker


Old Crossover


New crossover, first attempt to build one. Picture missing huge coil for the woofer



Drivers removed, Back of mid/tweeter is aluminum shell.



Back of cabinet with woofer. Cabinets are about 1.25' thick



Tube connectors installed



Current freq response.

I guess the two speaker connectors work. Have you noticed much improvement with the new ones? By the way, in Europe I have not seen them anywhere!

No Rez too?

PS: this week I wanted to change the cheap Bennic resistor of the KEF Q100 tweeter with Mills 5 watts but the other person could not be there and thus verify if we notice the difference between the two and how much.

I didn't put any No Res in the cabinets. The cabinet is thick enough. When tapping on them they are very solid.

I wrote the question before adding the image in which thick walls of chipboard are appreciated.

But... I am surprised that it weighs so little, only 11 Kg.

Do you notice the difference? With very good recordings with high dynamic range (DR). Like I have listened to hours ago:

MFSB - The Best Of MFSB (Love Is The Message) (1995), CD, Legacy / Epic / Sony, Europe
