Predicament..
The original MD500 midranges in my 66’s have the glue/doping on the speaker surface that hardens and cracks over time.
The MF500’s in my Beovox 5700’s are in ‘mint’ condition.
A few years ago I swapped the midranges over and they have sounded ‘fine' in their new homes.
The crossovers had been professionally recapped in both sets of speakers but no change was ever made to the 24uF/30uF cap which varies according to whether an MD or an MF midrange unit is fitted.
Recently I’ve upgraded my amplification and source in my main system which uses the Ditton 66’s. (Yamaha C4 preamp and P2200 power amp, Chord Hugo DAC - all recently recapped and serviced.)
Naturally, I want the 66’s to be performing optimally.
The question:
- For best sound quality should I swap the midrange units back into their original correct speaker cabinets or leave them as they are?
I ask because I’m thinking that the cracked surface of the MD500’s might actually cause more degradation of sound quality than using the ‘incorrect’ MF500’s - I've read that both midrange units' performances once installed in the cabinet are very similar.
- Also, is there a successful procedure for renovating the cracked/hardened surface of the MD500?
Would be grateful for any advice.
