Where's YNWOAN's thread on versions ?
To me the first version has the woofer with no protruding cone.
Then came a protruding cone with silver mesh over tweeter.
Then black mesh.
Then bi-wirable.
MDF came somewhere ??
I have two pairs of the black mesh ones, which I believe that these are early Mordaunt Short built ones.
I think that most of the 14's found in North America are the black mesh ones.
I'd like a no-cone early version in Walnut :-D
Not sure about this.
MK1 (a)
The VERY first version seems to be the one with the glued in port (like a drain pipe, no "lip" round the outside edge). Mine have shorter yellow bungs which cime out (but may have once been stuck in).
Concave centre to bass unit, obviously chipboard throughout. Cardboard - like gaskets.
Label on back saying "epos ES14 SPEAKER SYSTEM"
Capacitor value 3mF (might be 3.3mF)
MK1 (b)
The later version of the MKI's.
Removable port, glued in bungs which are grey and longer than the earlier version. No label on back. Concave centre to bass unit.
Synthetic material for gaskets (neoprene foam?)
Appear to have thicker chipboard walls to cabinet and finer material for back wall and baffle (could be better grade chipboard or MDF?). These cover the serial no's 2000 I think.
Capacitor Value same as MK1(a)
MKII (a?)
Removable port with removable bung, same as MKI (b).
Convex centre to bass unit
Cabinet walls thicker than MKI (a) similar to MKI (b) but not chipboard (?MDF)
Capacitor Value 2.2mF
All these have black mesh over the Tweeter, and are sitting in my "snug".
There seems to be a later version of the MKII (call it MKII (b)) which is BiWired.
There's photo's higher up the post.
Incidentally, in my system, the MKI (a) has a sibilant top end, the MKI (b) doesn't. The MK11 (a) is generally lighter in sound with punchier (but less) bass. Certainly not sibilant though.
And I know that this all seems a bit pedantic, but it would be really useful to be able to recognize the different versions as I have now bought three pairs which I thought were the same and they are all different. (I wanted to try some - bought a black pair to try, liked them but needed a wood veneer pair. Bought some "Walnut" veneer only to find that they were different (MKII(a), so bought a pair of "Cherry" MKI's only to find that they were different again!!
Hey Ho!
