Seems to me Eminence kinda fudged the Le Rating on the
"new" legend. Mechanical Quality and few others have changed as well so it is a different driver. But yah the model shows glorious highend because the gave a very low number for Le and this will have a big effect in the model.
A Le of .33mH is a little ridiculous for a 15. Model the legend with a Le of 1.1 mH then the model will kinda show more whats happening in the real world.
For the most part it still sounds like any legend I have heard.
Which is really just average for alot of 15's with a roll off around 2k
Which is the biggest difference between looking at pretty graphs
and actually hearing the driver.
anyhoo look at the Response chart of the Legend CB158
then look at the response chart of the Delta Pro 15a
Sensitivity advertised at 101 dB much much more highend.
handles about 40 watt less than a legend in bass applications.
But for a single 15 rig not much of a issue and the sensitivity is much better.
no im not talking about the standard series delta its the pro series Delta pro 15a
If your worried about the lowend response of the 15. Just remember how many dudes just do fine with weezy 10's
throw a legend 10" or some other eminence 10" in a standard volume of say 1.3 cubic feet, and then compare a 15" in 5cubic feet and right away you will see the difference in lowend.
The volume and tune you chose for the legend is a great choice.
5 cubic around 40hz. that driver sounds best in bigger boxes.
The Delta pro can drop in the same large box.
if you really concerned about power handling the Delta sounds fine in smaller boxes so take it down to 4 cubic and tune at 40hz.
