Good dispersion, excellent breakup performance similar to the SB Acoustics ridged drivers. If these have better bass performance they could be an overall superior driver.

Don’t know what the off axis angles are but if the second curve for the tweeter is 30 degrees, then the dispersion is amazing. Too bad it’s a full flange instead of compact.
 
L16RNX3 seems to be designed specially for active 2-way mini monitors. Their special intention is to make powerful punch and impress, rather than seek for elusive sound qualities. Strong magnetic circuit (large motor force factor over 11) is combined with particularly long linear stroke (+/-7mm) thanks to record-breaking 20-mm voice coil lengh in 5" class woofers. Great volume displacement capabilities are possible also with unusually large cone area packed into small frame. 104 cm2 in 146-mm diameter is remarkable! Long VC wound on extremely durable titanium former also means high power handling of 200W and good mechanical stability of moving subsytem. Break-up mode is thrown high becouse of the stiff VC former material used and probably more-than normal thick aluminium cone. Unfortunately, these design goals have also their serious drawbacks which nearly ruin this offer. 20-mm long voice coil generates very large inductance rise toward higher frequencies despite promises of shorting ring usage. If only they made good optimization, if not, fair amount of inductance-related distortion in the midrange will pop-out, negating advantage of break-up far away the pass-band. Weight penalty is also severe - 2x more Mms than usually found in 5" drivers so midrange sensitivity is below normal, despite its motor strength... The SEAS price probably will make it non-starter agains SBxxNBAC series of woofers.

20.8g Mms on a 104cm Sd and overall sensitivity of 84db with a troublesome looking response between 500Hz-2Khz. Inductance of 0.68mH - what`s the copper in the motor doing? Another no-no from the new Seas range for me (following the clearly marketing designed Graphene series).

The tweeter, however, looks interesting. Will be interested to see how it measures compared to the new peerless DA series.
