Hi Develsindetails, slightly off topic, going back to your problem of posting photos, as Dave says you need to save the file as a jepg. Lots of free programs will do that, you don't need anything as powerful or compicated as photoshop. Check out Irfanview and Picasa , I think both can do that. Use the "file" "save as.." function. However these are really photo viewers rather than editors, and there are others that are more powerful, but still free. Other members may have good suggestions.
I too once owned a Kuba console… My wife would not let me restore/keep it - so I scavenged what I could… The radio is plain cute and one day will be restored. As well, I pulled a pair of 5’’ by 10’’ IREL speakers out of the console and stashed them away. Mine are with ‘normal’ alnico-T magnets. Last year, upon building a SEP EL84 amp I decided to try it with as many speaker combinations as I could. One combination was the above mentioned pair of IRELs (3.5 Ohms) hooked up in series to a pair of 3’’ by 5’’ Isophon (8 Ohms) alnico speakers. No crossover. In an ‘open baffle’ (on top of the kitchen table, LOL). The result? One of the most natural and life-like aural presentations I’ve ever experienced. With any type of music.
My initial listening impressions of the IRELs (using a similar minimalist open-baffle approach) mated to an SE amp I salvaged and upgraded (from a Philips console) revealed the same sonic potential. Thanks for your listening observations fullrangeSR!
On pictures I posted motors are mounted inside, similarly. I posted my pictures to show you that you speakers do actually have motors, but on the opposite side of the frame, unlike the majority of speakers. Such drivers were usually made for TV sets, to minimize magnetizing of TV CRTs.
Yes. I understand that Wavebourn. Thks for contributing. I truly appreciate it.I just get naturally curious when I see a unique variation on standard driver construction or application.
As I have subsequently learned these IRELs are in fact quite unique from the pack of other front mounted motor designs and that space and magnetization issues were not the reason behind its design.
Here is something similar:
This speaker was used in some early 70s Russian color TVs
I think the primary reason for the front mounted magnet structures is for compactness. We did an in-wall sub at PSB with a 12" using a front mounted neo structure and were able to get it to fit in the standard 3 3/4" stud depth. A radio/console maker would have some units where losing the magnet structure thickness (it moves to the inside of the cone so you pick up that dimension) would allow more room for electronic components. Most portable radios have to cut out a significant chunk of real estate to allow the speaker magnet to poke into the plane of the electronics componetry. Note that even if that didn't apply to the particular model the units were pulled out of, they would be from a common parts bin.
Being Alnico, the units are inherently magnetically shielded, so no advantage there.
In the case of the ferrite structure inside the basket but outside the cone, this is still slimmer than the conventional units would be. There may be a little shielding from this configuration but I don't think that ws the primary reason for doing it. Sometimes you are just looking for a way to make off the shelf parts fit.

by the way, i did some more accurate research about IREL, it seems that the original company which had just one plant in the Molassana borough of Genova, actually went bankrupt in 1987, part of the tooling and raw parts has been acquired by Montagna, an Italian high end speaker maker.
IREL speakers were extremely popular right up to the company's bankruptcy, not only they were used by lots of Italian manufacturers, but also by many European ones like Telefunken, Blaupunkt, Salora, Saba, Uher (most of the speakers used in the Report line of recorders were made by IREL)
IREL speakers were simple and inexpensive but sounded really good, many of the original 60s models were still made with little changes at the time of the company's demise and they were still painted dark blue and often still used horseshoe Alnico magnets even for cheap TV set speakers.
By the way, the inverted magnet models are meant to be installed with a fine cloth screen in front of them to keep dust off the magnet's gap which is not protected by the spider as in most conventional speakers.

used some speakers of similar construction in the doors of my first car, a 1953 VW because they where shallow enough and had the biggest membranes I could find. It was fed from a
poweramp with transformers and Germanium transistors and could deliver some real 15W despite the fact that the battery was only 6.3V. It was 1 speaker in every door and they where able to make a lot of noise and rattled the doors but the the sound was not anything I would like to listen too nowdays.
