I honestly do not know.
The 12Q was before my time with the company.
My guess is that if it was called a "paper weight" was due to the fact it would not have been cheap, 4" coil with high inductance, more SPL oriented, which is not the group we try and market to.
It was a one off product that was kept in the companies personal collection, until we had no need for it.
Its more of a conversation peice for collectors of rare speakers.
Flat cone 4hp.....you wont see another one of those floating around.
