The Ampeg SVT-410HLF Enclosure gives you plenty of volume and clean low end. This 4x10" cabinet has the same speakers and 1" horn as the SVT-410HE with 2" coils and 30 oz. magnets, but the cabinet itself is tuned differently. It's deeper and has a bottom port that results in better low-end response, down to 28Hz!
