Here's something I found:

ID'ing old Magnavox console components

"Here is what I do know:
This unit was one of Magnavox's first solid-state versions ca. 1965.
It was about 6 feet long with removable sliding wooden panels on the top.
The control unit and record-changer were in the right-hand side.
An album storage bin and speaker selector switch were located in the
left-had side
The amp was 50 watts and was remotely located in the bottom of the cabinet.
The woofers are 15" in diameter and say, 'Magnavox 581515-1 719' "


probably not full range then. But if you search for the part number you'll find other reports of similar consoles. Can you measure them?

The Magnets look very small and do not look to be ALNICO but the over all build quality looks good. I wouldn't expect them to handle a lot of power but the light weight paper cones should give decent mid range performance. They would most likel make an excellent guitar speaker. Just guessing though.

What makes you think they are not alnico? They come from the right era when the surround was part of the cone. They might be a good candidate for an OB in the garage or WHY.

Don't recall numbers anymore, but they sure look like what I used in early 48" high x 2 ft^2 open bottom TLs, so high Qt. Fs was around 40 Hz and had output to 10+ kHz for good overlap with a 1st order XO. My memory is they're AlNiCo, but an easy way to tell is wave them around a CRT TV or monitor, small compass, etc.. If it doesn't affect it, its AlNiCo.

Hi,

Nice guitar speakers IMO, suit most probably jazz guitar, open baffled.

They are AlNiCo magnets, couldn't be anything else with that shape.

Other than retro radiogram / jukebox rebuilds, not suited to hifi.

rgds, sreten.

critical point. I guess most of the ALNICOS I've seen have that horseshoe looking thing around them, but it looks like I'm wrong. I don't have a lot of experience with old speakers so I was giving my best guess.

Why don't ALNICO magnets effect CRTs?
