Is it true that JBL drivers have a high BL no. therefor prefer bass reflex loading? I just assumed due to there being no front horn loaded JBL in my experience while most Altec woofers appear in front horn loaded cabinets. And the Altecs favoring larger cabs in the 8/9 cu. ft. range while JBL's somewhat smaller 3/6 cu. ft. seems to predominate in home speaker applications. Even the JBL home 15" D 130's are rather different than 2226h/j's in their specs. I only ask since there seems to be varying opinions on how each driver should be used over the past 40 yrs of experimention.
