This is the speaker enclosure people mean when they say SVT speaker cabinet. Its all about tone. Other than the color scheme, it is identical to the original SVT-810. Why eight 10 speakers? We learned early on that 10 speakers work much more efficiently than fifteens or eighteensand if you put eight 10 speakers together, you can move a huge column of air. Youd need five 18 or six 15 speakers to move as much air as the SVT-810E! And they simply wouldnt be able to respond to transient peaks as quickly as our tens.The SVT-810E is still manufactured using the same design dating all the way back to 1969. The Infinite Baffle design of these sealed enclosures produces vast amounts of tightly focused bass. Thats why youll find the SVT-810E on stage with such artists as Chris Squire (Yes), Geezer Butler (Black Sabbath), John McVie (Fleetwood Mac), and far too many others to list here. In the world of high performance bass cabs, the Ampeg SVT-810E stands tall and proud.
