DRIVE UNITS BY MANUFACTURER:
753 XOR
NOW SUPPLIED WITH AN EASY CONNECTION COLOUR CODED LOOM.
PRICED PER PAIR.
The Mission 753 crossover features general purpose polarised electrolytic capacitors wired back to back (in series) as a cost and size cutting exercise.
Featuring point to point wiring and a wealth of hot melt adhesive, the crossover build quality is typical of the era - it is quite tricky to work on for beginners as it is in the form of a split section PCB sandwich connected by brass bus bars.
Our upgrade includes various changes and modifications that take these speakers to a new level of performance - please see the reviews.
How does this work ?
Purchasing this service generates a unique job number - you will receive an email with instructions of how to send the crossovers and our workshop address.

Finally got my electricity back today after the storm on Friday. Initially I was a bit apprehensive, as I had no experience in electronics. As I followed the colour coded looms, it got easier and more straightforward. Guess what! My Mission 753s sound better than they ever did in 1998 when I bought them brand new. New crossovers also brought one of my tweeters back to life (was dead for ten years) What a quality upgrade, worth every single penny. Willy and Caroline, you guys are legends.
Thanks for the great review Lamaat - enjoy the 753's !

So I did the tweeters a few months back, and they were a revelation. I debated the crossover upgrade a while- but I decided 'in for a penny' and went for it.
Wow!
I fully agree with the other reviewers here, they pretty much nail it.
The units are very well put together, and ooze quality.
Overall tonal balance is improved, clarity and soundstage (particularly in the mid/upper-mid) is significantly improved, and the 'air' added by the new tweeters is given another boost. But the biggest thing is the bass- there's more of it, it goes deeper, and is superbly tight and controlled.
Dropped my standard test-track (Groove Armada's Suntoucher) and it left me grinning like a small child who's just left his mam a present in his nappy.
So if you're in two minds, I say go for it. I paid a ton for the 753s on Facebook, £400-ish for the tweeters and crossovers- and I don't reckon you could beat them for less than 1500 quid now. The improvement is more than I expected, and I'm now pulling out CDs I haven't listened to in years.
Worth every penny.
I'll sign off with a mention of the superb, personal service from WIll & Caroline. It's not often these day you feel truly valued as a customer, so thank you!!
Thanks for the review Jon, we're glad you like the upgrades !

The newly rebuilt crossovers look fantastic and the wiring was easy to reconnect due to the colour coding. After reconnection I tried everytype of music from Bach, Faithless, Pink Floyd and the Dub Pistols. The sound was brilliant, it seemed to be less muffled. The sound seemed to be crisper and was clear in the mid range and the bass was punchy and clear, giving the sound a more distinctive punch. Overall the upgrade was worth every penny. Can recommend this upgrade to anyone with 753's, it does improve them hand over fist.
Thanks for the review Russell !

I am very impressed with the performance improvement of these new crossovers and replacement tweeters that are now in my Mission 753's, a great improvement on the originals, a pair of speakers I've had from new. Thank You.😊
Thanks for the review Colin !

I came across this upgrade for my mission speakers I had from new in 1990.The sound improvement was immediate and gives a superb bass response and improved overall sound to what was already a great loudspeaker.Fitting was easy.I now plan to buy the tweeter upgrade for the loudspeakers.
A great upgrade,remarkable.
Thankyou for your review Michael !

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.

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.

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.
