It would be nice, but I´m not sure if it would really help. After getting some of these in my paws, I know that specs are not enough. It simply is not... I now own two pieces of B&C speakers 21DS115, and one(soon two) RCF LF21N551. If Beyma isn´t way cheaper, I´m not sure if I would recommend it.
should add Eighteen Sound Tetracoil 21NTLW5000 ( 1800W AES / 4,000W program, 17.5mm XMAX, FOUR voice coils 4.5 inch each in two magnetic gaps, symmetrical push-pull motor ) ... theoretically it should offer performance that isn't far behind B&C but at significantly lower weight. in practice i don't know how durable they are, but i want to build some subwoofers out of this driver. it comes in 4 and 8 ohms.
Too bad they discontinued RCF LF21N551. That was a beast. I am not happy that I got rid of them. Maybe substitute could be LaVoce SAN215.30. I would die for new RCF IPAL class 18" speakers.
And non ID model, and RCF LF21N551. It is solid, and belongs just under 21IPAL and Eminence, if one wants to use the excursion. Both 21SW152 and 21DS115 cannot touch it.
