You have drivers? We have the Mastering Lab Crossovers and ML10 custom cabinets ready to go!
The much sought after ML10 used the original Tannoy SRM-B/SGM-B 10" Dual-Concentric rolled-rubber-surround paper cone driver with the Mastering Lab Crossover. Manley and The Mastering Lab jointly-commissioned the last ever production of this famous driver to build a limited run of the ML10 before Tannoy discontinued the SGM10 p/n 2558R driver around 1992. The beefy, dense, non-resonant cabinet was constructed of 1 1/2" thick MDF finished in black formica with either 1" thick solid walnut or cherry sides. These sides served to protect the corners of the cabinet. (There do exist some early ML10 without the solid wood side bumpers and yes, we observed folks dinging the corners of the formica slamming into walls and doors which is why we added the solid wood side bumpers!)
The Crossover was The Mastering Lab's creation. They had been retro fitting the crossover into little plastic boxes banged on the back of stock Tannoy SRM-B/SGM-B 5/8" ply cabinets before this joint project came to light. The idea was we would design and build strong and heavily braced new cabinets 15" Wide X 10" Deep X 22" Tall weighing in at 50 lbs. each, order the drivers and build Doug Sax's crossover into these ML10's with proper production techniques, all with the crossover controls mounted on the front for the first time, and Bi-ampable/Bi-wireable recessed five way binding posts on the back. The dream speaker was born. People really started crying when they all sold out!
The ML10 offered point source localization combined with absolute time alignment, low distortion and phase coherence. Amplifier power of 100 to 200 watts was recommended. Designed to provide the recording engineer with a highly accurate yet musical tool, the ML10 is now a highly sought after collectible. Used, they are selling for much more than the original retail price of $2950.00 USD. We have seen them selling for over $4000/per pair.
Sooooooooooo.... we created the ML 10A follow-up design to "keep the dream alive". We went on with another then-current production Tannoy 10" Dual-Concentric rolled-rubber-surround paper cone driver (7900-0267) #2598 as found in the 1992-1998 Tannoy Stirling hifi model. A new crossover had to be used with the newer driver to compensate for the different balance of woofer to tweeter efficiency in the newer driver. Approximately 50 pairs of ML10A were produced before we decided to discontinue the ML10A project.
But hope does exist!
Yes we do offer to swing YOUR SGM-B/SRM-B 10" drivers into our big beefy ML10 cabinets and install the Mastering Lab Crossovers for $2000 per pair, just like the original ML10. We are currently using a beautiful Lyptus - wood with a medium cherry stain sealed with a hand rubbed waxed finish for the solid wood side panels.
ONLY the SGM/SRM/SGM-B 10" Tannoy drivers will work for this. The Tannoy driver part numbers are (7900-0071) #2558 for the SRM driver and (7900-0132) #2558R for the SGM driver.
No LGM 12-inchers, no older LSU/HF/IIILZG/8U or HPD type drivers may be used in our system. ONLY the SGM-B/SRM-B 10" Tannoy drivers!!
Here is the driver that works:
See below for what you may NOT use:
Even though the fronts of the drivers look similar, if the back of the driver you are thinking of installing with the Mastering Lab xovers looks like this, then you have an older LSU/HF/IIILZG/8U or HPD type driver and it will not be suitable for this particular crossover. (Read: it will sound very strange. Keep your original setup.)
CURRENT STOCK STATUS 4/2015: We have NO SGM/SRM10 drivers in stock right now, sorry.
We always have plenty of cabinets + TML xovers available if YOU have the drivers. Factory-direct cost is $2000 for the pair of cabinets and TML crossovers (using YOUR drivers).
(And yes, we also provide the strong shipping cartons and packaging as part of the deal.)
If we are installing your drivers in our cabinets, you are welcome to ship us the drivers so we can test the whole system with your drivers. But you do not have to. If you prefer not to ship your drivers to us, we can test them with a set of drivers from our ML10's that we use in our QC room and you can screw in your drivers yourself. Four allen bolts and a Molex plug and you have installed your driver.
FAQ ML10: Can you just sell me the crossovers only so I can put them on my Tannoy cabinets?
Answer: Sorry we are only allowed to offer TML xovers complete in our cabinets as a whole system. You can contact The Mastering Lab and see if they could sell you a set "stand-alone" with their external mounting kit.
And that's the story!

Recones and Repairs:
As part of upgrading your old cabinets to our new ones, we will check over your drivers to make sure they are in tip top shape and both drivers sound the same. If you are having trouble with your old drivers we can sometimes fix them and/or recone them for you for an additional charge when we are installing them in the new cabinets. We keep the SGM recone kits in stock and can also order more from Tannoy. Actually if your drivers require a recone, we will order a new pair from Tannoy for you in order not to deplete our stock. The SGM woofer recone kits run about $250 each, and our shop rate is $125 per hour for repair time. Gamma is very good with these.
