X4 mofos!
i find the bass perfect on the DF's. hook them up to a powerful amp with low output impedance and properly direct-coupled(lot of direct coupled designs tend to roll off the low to sub-bass. that's why lot amps back in the 80's were very high bandwidth design going from DC to 170,000hz at half it's given output to prevent roll-off and stay flat at full output from 20hz-20,000hz with very little to none negative feedback).
not just amp but high voltage source as well people always forget. any professional balanced audio interface or mixer will provide a +4dbu gain(1.23v RMS) off it's balanced outputs. that higher voltage will feed higher voltages through the preamp(which is already high voltage to drive the power amp. preamp avg 1.2-1.5v rms and can deliver max output of 5v to allow the power amp to reach maximum dynamic headroom if needed). the DF was design around high gain professional mixer boards and equipment and everyone knows professional equipment fellows atleast the +4dbu gain rule. sometimes it as high as +10dbu(maximum output is 7v rms) but only used for very high powered,power amps and powered mixers. all consumer gear and equipment is -10dbv which is well under 1v rms. there is about 11db difference between -10dbv(consumer) and +4dbu(professional).
