Hey Fred!
Those definately are some 'interesting' set of drivers there from Lambada. Thanks for the link.
I'd 'expect' these drivers to be great for 2-way applications, especially where you need to use their mid-range capability and cross-over relatively high.
However, if I was to use them exclusively for bass and cross-over at about 200-400Hz, these drivers wouldn't figure in my list of choices. More so if I intended to push it to it's power limit.
1. The cone-profile is curvilinear, under high excursions, this profile cone does tent to flatten from the outside more easily. Also the MMS is only 70 grams, implying that the cone+surround assembly weight would probably be around 40-45grams. Being a paper based cone, this means that it is probably thin and not very strong - again more prone to de-formation. (The cone might not get permanently damaged, but it will just be more flexible.
2. The X-Max of 3.3mm: Despite the normal magnet weight and 2" coil, this driver boasts an impressive Bl of 27.6 T/m. I would give credit for this primarily to the 18mm Flange and to some extent the 4 layers on the coil. But beware - as the coil starts to move more and more out of the gap, the magnetic field drops fast and one would find a substantial drop in the Bl.
Again, there is no doubting this driver's capability in the mid-range, and it might be very useful for low-power home-audio applications, but in my opinion, not for PA and if you like it ta hit u hard!
I have no personal experience with this driver, but I design drivers and am still learning! I've been dreaming lately about a 15 or 18" driver with a mammoth 18 lb magnet for bass-horn applications.
Rgds,
Sanjay
