monacor sph135ad and sph135tc with dt252

[beboni]

hy folks !
does anybody know something about these drivers because iam planning to make some speakers with them.

they shoud be three-way speakers {slim enclosure}

for woofer:
-2 x monacor sph13tc dual voicecoil so parallelig two drivers i get 8 ohm impedance
Win ISD gave me these calculations for them:
volume-36.6 lit
-tuning 38.4 hz{-3 db}
BR pipe diameter 5cm and 7,2 cm long

for midrange separate box 5lit driver is monacor sph135ad driving from 200-2500hz {12db}

and for tweeter monacor dt252 from 2500-20000hz

crossover would be combination of pasive and active crossover

i just wanna hear professional opinion about this idea {that 2 smaller drivers could give fast deep and god definition of bass}??
thans!
