On placing fullrange baffle or non baffle (even closed box) spakers to the place they trully deserve

At your risk. They sound amazing due to their point source coherence etc but usually there is an annoying mid high heaviness that can hurt. So this is an option. Adding an say 1.7mH inductor in series to cut mid, midhigh heaviness, ie treeting it like a woofer. Then to restore high frequencies a resitor of say 29ohms is placed in parallel with said inductor. the resistor can be variable until one gets it right. Results are promising. These are values used with the great Fostex FE-127E 4.5ii fullrange placed on a Pioneer cs-353 box. Unboomy deep articulate bass, natural mid, sweet highs. It works nicely with other great full range speakers such as a 5ii by 10ii Grundig on baffle etc. Tried also sussesfully with a Staren 5ii fullrange and a Bayma 8ii fullrange. If a woofer such as a Philips 8in is used it may be preferable to uise a small say 1uF capacitor instead of said resistor in order to enchance high frequency response, ie treat the speaker as both a woofer and a tweeter!, see a previous post on speakers with or without baffle.
