I have two pairs of these speakers, it is a treat. In addition to being a format that can no longer find these days, they are simply gorgeous.
When listening, they have a very particular sound (low to 90Hz), which gives a bass effect "dry" and not "fat" as do the bass reflex. Note a slight lack of midrange to compensate at the amp settings.
Speakers perfect for fans of jazz or classical.
Only drawback, it is difficult to find HP replacement.
I bought it in a warehouse sale. In super condition.
It is marked 50 Watts 8 Ohm.
2 channels. The Big HP is advanced low compared to the rest of the chamber (phase inversion, which is now with electronic components}. It seems solid (tar paper for the front suspension}
The sound is very punchy. The large paper mailings membranne super low net well. They sound very good (well balanced volume} dscendent but not as low as some closed. The tweeter is difficult to judge, I would say ... glitter (not cool MP3 ...}
In a small apartment with a good sound, they're perfect. Not being listened to Mozart, but the good fat electro.
