Lin - classic speaker guru par excellance and Rofiel - mono aficonado
Rofiel found this Jensen M10 field coil 13" driver (OEM WE TA4151 - more info) stashed in an ancient garage 120 kms. away from Manila
I revived the tube rectified power supply with fresh Sprague ATOM capacitors. Since original replacement cones are unavailable, we took it to Lin for restoration.
The result of Lin's...
...painstaking labor.
To augment the top end, we added a phenolic diaphragm'ed Jensen RP103 alnico horn tweeter through a simple DIY crossover
Rofiel designed a Klangfilm inspired open baffle using phenolic plywood with piano hinged wings to maximize bass yet convenient transport.

Hi Je! First off all - thanks for your amazing blog and your contribution to all audiophile world. I’m very intrigued to make mine version of similar open baffle for mono system. However Jensen M10 is so rare, that I almost lost my hope. So my next thought was to pair Jensen RP-103 with Jensen F15LL. What’s your opinion? Can you provide holes in my concept, or where I will miss something? Also, maybe there is availalable blueprint with dimensions / matereals of this open baffle?
ReplyDeleteThanks in advance :)
