The 511B and 811B differ only in cutoff frequency and size

Made in the USA! These horns can be found in the ALTEC "voice of the theater" speakers, and have been used by all of the best known bands of all time live on stage! I have two pairs of Altec horns, one each of the 811B and the 511B, and I've always wondered what the big difference between them is, besides the fact that one can supposedly be crossed over lower? In most of my older Altec information, Altec actually crossed over both of these horns at around 1200 HZ. Used Altec 511B for sale on 400+ second hand hifi sites & shops
