Pleiades filters for speakers?

At your risk.


Some 70s battery radio cassette players equalize what goes to the speaker for increasing bass from the small radio enclosure. Examples could be JVC radio cassette players, or a Beolit radio etc.


Would Pleiades RL or RC wavefilters do the trick as a last resort in case a satisfactory small fullrange speaker cannot be made?


For example an inductor in series with amp output and a resistor in parallel with inductor.


Or a capacitor in series with a resistor and the total in parallel with speaker or amp out.


But then they are the inverse of Pleiades filters for microphones.


Would a straight microphone amp small speaker chain sound flat frequency response to listener's brain?


Possibly not, as the problem might be the predominance of midrange. Different turnover frequency may be needed for mic or speaker. Not sure yet.


Wave filters can equalize at the expect of sensitivity, efficiency.


It is hoped that the Pleiades Auratone 5C type speaker with the Tesla 5in fullrange drive unit might not need EQ as it is less sensitive at midrange. It is hoped at at small distance it can be connected to just headphones out.
