Bass from DML's is design dependent. There is a flaw in the exciters design so bass is limited, this is why the BMR was invented as it fixes the exciters flaw. There is also a reason why a BMR driver is (3.5) "SMALL".
Its not really about the beaming its more about the dispersion. High frequencies come out of the center/middle of the cone are closest to the voice coil and disperse outwards towards the edges of the surround material hence why the whizzer cone or plug/dust cap is in the center of the driver. The larger the diaphragm becomes the less prominent the highs will sound as it has to travel across that huge surface area. The smaller the diaphragm the more prominent the highs will become as it does not have to travel that far from the center. This is why smaller panels will have better high frequencies as opposed to larger panels. When you throw a pebble into the pond the highs are in the middle and radiate outwards untill it reaches the edges of the pound but the bigger the pond the weaker the ripples become once it reaches the edges. Not sure if you understand my analogy? lol
Look at the paper cone tweeters on P.E. Most people dont realize that some of the sound radiating off that
"paper", cone tweeter is coming from the MYLAR and or ALUMINUM dust cap in the center which increases the high frequency sounds....I AM GIVING YOU HINTS LOUT. lol
My question to you is have actually HEARD them side by side?....as two drivers can have similar specs but sound fairly different which will further prove that the whizzer cone/phase plug/dust cap does make a difference. I highly doubt that a reputable brand like Tang Band (or any other high end brand) would use whizzer cones on there bamboo full range drivers just for gimmicks.
