but in room, generating tones on true rta they seem solid to below 40 hz before amplitude begins to dip and still have good output to around 35hz and seem to load the cone very well with little cone movement at kidney massaging levels

i realize thats very subjective as far as empirical evidence goes and would love to properly test the in room response, but the real point of the post was that this driver will definately not sound bass light in this cabinet and imho it would be as shame if the poster did not give karlsons a try as they are an easy build and he now owns some of the best drivers for them. i'll bet a bass reflex with this driver would be no competition

nothin to lose but time, money and plywood
