This is the speaker cabinet for the bass player who demands the ultimate in a single, compact cabinet setup. The SVT-410HLF delivers devastating low-end bass, all the way down to 28Hz, thanks to four 10 inch speakers working together to move a tremendous amount of air. The SVT-410HLF actually moves 10% more air than two 18-inch speakers, and 25% more than three 15-inch speakers! And those leviathans simply can't respond to transient peaks as quickly as four tens can.
