HISTORY:
This 4" mid range was removed from an old Sansui DA-P500 stereo system, a budget unit from the days when Sansui (and many other Japanese manufacturers) went down the price spiral and cut costs, in short - horrible plastic little jobbies!
Anyway, these Sansui's have nice LARGE volume speaker cabinets and as the main system unit had failed, I decided to have a look inside the cabinets.
3 way system (all speakers are on my advertisements, as separate items) and this one is the mid range speaker (one channel)
These are NOT Klipsch's by any stretch of the imagination but they are "adequate" general purpose, fairly low power requirements.

Generic Mid Range driver (ex Sansui)
1980's era
Part # E10BP45-66F
4" cone *** special note ***
I am not sure but I suspect this cone is not paper based. It is obviously cream/white colour but it looks and feels different to paper. Much smoother to the touch than a paper cone, it may be some type of polymer or kevlar perhaps. If you look at the photograph of the cone you can see a "light pattern", that is NOT the cone material but light reflected from the roof - the material is quite reflective.
15W RMS power handling
8 Ohm impedance
Total weight: 300g
Magnet size/diameter: 45mm diameter x 15mm deep
Made in Taiwan
COSMETIC CONDITION:
Everything looks ship shape, no damage to any part (cone, surround etc)
Basket (fully enclosed) is in "as new" condition
Spade terminals are secure and clean
TESTING:
The DA-P500 system was only used for low level background music, to entertain guests - nothing special from an audio point of view.
Before removing from the very large (massive but no porting and absolutely no wadding inside!) loudspeaker cabinet(s) I checked the loudspeakers - each individually (tweeter, mid range & this woofer) and listened closely for scratching or other strange cone/voice coil noises - nothing heard, in fact the audio is nice and clean - pretty good and better than I would have expected under close audio scrutiny.
The basket is pressed steel, closed frame
4x mounting holes around the rim.
I connected these to another system I have under test here (Technics SE-A808) and slowly pushed up the volume while listening to how the loudspeaker was handling the music. I went right up to approximately 20W RMS and the audio was still nice and clean - I went no higher than this.
Just a note about these mystery Taiwanese speakers. Back in the day, these exact same speakers could be purchased from Radio Parts (Melbourne) in 1980 for A$12 each - they were sold as generic but reasonable quality loudspeakers, not high end but not "bottom of the barrel" types either. Radio Parts would only identify them as sourced from the "world's largest manufacturer of speakers" in their advertisements. I do not know which factory pushed these out, Taiwan had MANY audio (and specifically loudspeaker) manufacturers in this time period but it is pretty obvious that this woofer was made to a price point, which explains this choice by Sansui for their "price conscious" DA-P500 market.
So in summary, a reasonable mid range loudspeaker for general, low power needs
Since removal from the cabinet, checked and then laid onto stiff cardboard (cone down) and sealed in plastic to ensure no dust contamination
PLEASE NOTE: this advertisement is for ONE mid range loudspeaker but I do have TWO. If you purchase the 2 of these in my store checkout, a discounted price (for buying them both) is automatically applied.
