Is this low-freq driver a rigidized versio of the 515 or 416. I see that it won't reach down too as low as the 515 or 416, but 421 can play very loud.

If you are talking about a cast aluminium 16" frame as rigidized then yes.But a 416 or 515 not sure what you mean.
Ruggedized = higher temp glues and for the voice coil, and stiffer cone to take the more violent excursion of musical instrument speakers. I was wondering is the speaker based on a 515 or 416 magnet structure/frame. I've heard that some musical instrument speakers are based on the company's hi-fi speakers.
All you have to do is either look up the specs or look at the speaker.Quote:

Since the 515 and 416 are both Alnico, the answer is pretty easy. No.
The 418 can be converted to a 416 by reconing.
There is no MI speaker close to a 515.
The 420 Biflex can also become a 416.
Good info, thanks!
Old Guy: Thanks for the info. I was just wondering if there was any equivalent to other woofers. Sometimes the frames and magnet structures are the same except that they use a different cone and voice coil that can withstand the more punishing musical instrument sound.
I had a friend who used his hi-fi speaker as a guitar speaker, and that was a "no go," the voice coil overheated and there was literally smoke & flames where his voice coil used to be.
Smoke AND Flames! I hope that happened on stage--would have made for one hell of a pyrotechnics display! Talk about a "smokin" guitar solo....Quote:

Would hate to do that with a pair of Altec drivers! :eek:
The 421-8LF is a bass driver and it has been used in place of the 416 or 515 for professional use. I am thinking of the 828 cabinet. There is the A7 and there is 1236.
