I recently cloned the circuit of my Krielser 11-104 stereo (which I found by the side of the road years ago). I replaced the 6M5s with EL84s. Using a single channel, it sounds good through an old Plessey 12PX film projector speaker, but I want to get some appropriate speakers for it. The original unit used 8 inch Rola speakers. Can anyone suggest some current production speakers which would be a good match? I doubt that I need 12 inch speakers. I'm thinking maybe 10 inch. I'll make my own enclosures. I won't be listening to high volume doof-doof music or anything like that. Beatles, Beethoven, Miles Davis. That kind of thing. My output transformers are Hammond 125CSE, with a frequency response of 100Hz-15kHz. Thanks.

The 12PX was a great speaker & I still have a pair in use but as a replacement for your Kriesler have a serious look at the Altronics C2000A which is a 200mm (8") twin cone . $15 each & good for 10W RMS.

I built a pair of sound columns for my outdoor cinema using 4 each of those speakers in series parallel in each column to give me an 8 ohm load on a pair of 50W RMS valve amps for L & R channels.

They had to feed an audience of 330 people or more on busy nights & they worked brilliantly until I had to replace them as the boxes started to fall apart being wooden & in the open thus copping the occasional summer rain storm..NOT possible to bring them in and out each night as high up on a 10M wide screen.

Thanks Lindsay. That's the kind of info I'm after. At $15 each I have no excuse for not buy a pair and trying them out. I I don't know how the original 8" Rolas compare with speakers today, but they sound quite good for a unit designed for low level home use. Good 3-dimensional sound, never harsh, good bass. One of them even has a hole in the cone, courtesy of some form of insect life. Still sounds fine though.

Cheers
John

Well if the original Rola's were simply single cone type & not the 8MX twin cone variety then you will be rather pleased with the Altronics C2000A with twin cones..nice & bright sound.
