Hi
i am starting a new open baffle project and am looking for an open baffle midrange with high efficiency that can cover
500-2000hz . i am considering running them naked AKA no baffle, possibly in a MTM configuration, so two midrange drivers would be used.
candidates i have researched so far are :
Audax PR170MO
great reputation , amazing efficiency , but ridiculous 0.5mm driver exursion (???)
PHL1120
looks good , 96db efficiency, 2mm xmax
B&C 6MD38, 96db , 2mm xmax
18sound 6ND430 92.5db , 2mm xmax
Acoustic Elegance TD6 Dipole 91db , 3mm xmax .
these are all 6.5" drivers as i think that size would suit the OB best , considring 1st dipole peak .
smaller driver is also possible .
below i will fill in with two Acoustic Elegance TD15LO which play from 80 to 500hz but could go higher .the low bottom is covered by a boxed sub.
tweeter is Beyma TPL150 , at this time just with the open back , but i plan to either build a dipole horn/waveguide for it, or to purchase one that will shortly be available.
crossovers and correction will be done by a DEQX so high slopes and EQ is not a problem.
any experience and/or comparison and opinion about the mentioned drivers or others that fit the requirement is much appreciated .
