[QUOTE="Uwe Riemer, post: 214285, member: 394"] Hi Kim, IMO a good midrange enclosure is small and tuned highish with small and therefore short vents, to keep pipe resonance out of the passband and if you cross over at 80Hz, you`ll want the 15" driver to have high max SPL around 100Hz. An 80l enclosure tuned to 50Hz with 230 cm2 does nothing of the above. The best midrange drivers according to my sims are 15NMB1000 and 15P80ND, though Xmax figure of the Beyma is interesting with voice coil overhang of 8mm, but both drivers would need an enclosure and tuning very different from yours. 15NTLW probably needs tons of power, but I heard good things about it ( from my dealer :unsure: ) Sims are not reality, so pick up whatever driver you like best, but be prepared to make sawdust, if it does`nt work out well. Like Peter Morris once said: I would not buy a low/mid driver without demodulation ring anymore ( exception 15NTLW ) From your list of drivers I want to use 15NDL88 with passband requirements similar to yours, but couldn`t give it a real world ride for obvious reasons.
