The biggest secret in audio world revealed - The cheap Altec Lansing 920-8b but much better as most

I am not smart to reveal this secret to you before I scored a set myself, because after this video the prices will not stay this cheap. The Altec lansing 920-8b is from 1993 and used in stage monitors. The altec lansing 920-8b is a 12" full range driver with a woofer, mid and 1.5" tweeter. Frequency response is 70 to 15.000Hz. When you can score 2 of these drivers you only need to made a big enough cabinet(see google for the best size) And if 70 Hz doesn&go deep enough, you should built that cabinet in a transmission line principle(make the bass path longer) If you can fscore the 920-8A is also a good driver with other specs as the 920-8b With the price these drivers / speakers cost you can say, without any doubt, that these are the best speakers you can have for this and much higher price
