The foam grill covers of my Mission 770s crumbled into dust many years ago. Only recently was I able to find what I thought would be a suitable replacement. Everything about the process went smoothly. The foam cut easily, looks good and, to my ears , is audibly transparent.
Has fixed the slight grainy sound on my old Mission 771s. The tweeter had a stain on the back suggesting the fluid had escaped. Make sure you release(unsolder) the coil wires before splitting the tweeter. Audax have replacement tweeters TM025C1 albeit 8 ohm which is another way to go.
Couldn’t be happier, more detail, more clarity. Vocals massively improved and less harsh sounding. Thanks Willys hifi.
Very flexible and easy to work with cable. Made up 6.5m cables shielded with some faraday tape and added PET cable sleeving outer and terminations of ChordOhmic bananas . After about 25hr ‘burn in’ compared with my NAC A5. IMO a better sounding cable, definitely better soundstage.
1990 Linn Index II LS120 Crossover and wiring upgrade.
Truly Outstanding performance upgrade flying in the face of conventional wisdom.
The resistor value is increased from 2.2 to 2.7 and is an official Linn Service 'performance' upgrade.

Carded lambswool replacing original poly wadding. Increased weight replacing 132g ea. for 215g ea. This was weighed out in stages and determined by sonic performance.
Small amount approx 15cm sq of Bitumen foam panel placed in two pieces in base of cab. (leftovers from another project.)
Jantzen solid core speaker cable AWG 17/ 1.15mm stripped of PVC outer sheath to leave only high performance PE insulation. Doubled and twisted Star-Quad. 2.3mm
x2 400mm lengths ea.
Replace binding post steel nuts and locking nuts on back of PCB with copper nuts x8 and locktight. (steel nuts in signal path???= Nuts)
Remove all Plastic front panels and rubber securing bungs. Seal air holes in front baffle sockets. (Holes!)
Total cost £190.00.
Worth every penny! The cost of replicating this level of performance will be many, MANY times this amount. This understanding determined my budget. Happy to spend £200 upgrading on a gamble for the knowledge and experience. The results are very serious for this money.
I purchased these new in 1990 and paid £220.00. They were never highly regarded but always delivered a satisfying sound I never bored of even though Bass is not a strong point in this sealed design. Proximity to rear wall is everything here.
No previous experience with crossover upgrades. Never built a PCB. Very limited knowledge of electronics A beginner !
Every sonic element is vastly improved. Detail everywhere, Soundstage opened up. Depth, Clarity, Definition, Truly remarkable the level of performance these 'nothing special' loudspeakers are now delivering. They are being driven by Oppo 105 upgraded, John Sampson upgraded Musical Fidelity A1. All solid core power/interconnect/speaker cables.
This project was only completed 'confidently' with the kind, generous help and insights from Willys HIFI who supplied all the excellent Mundorf components.
Cannot thank Will enough for his patience and knowledge. My lack of knowledge and understanding was never a barrier to success only because Will was so helpful, enthusiastic and interested in my enquiries. Will cautioned against my extravagant choice of caps. The results could not be predicted and so a more responsible and cost efficient choice was Will's sagely recommendation. Trustworthy, Knowledgeable and Approachable. How refreshing. My choice was a gamble to push the limits and the budget, the results are beyond my hopes and expectations.
Highly commendable service and support. Outstanding in the Audio/HiFi marketplace.
Thank you Will.
John.
