What the manufacturer says:

"With its four specially designed 10 inch speakers, 1 inch horn and dual front ports for extended low end, the Ampeg B-410HLF was born to rock hard and low. Suitable for most sizes of venues, the 4-Ohm enclosure handles twice the power of the B-410HE and features heavy-duty recessed handles and detachable casters. The extended range of the B-410HLF makes it ideal for 5 or 6 string bass players seeking solid low frequency performance (all the way down to 40Hz), with shimmering top-end up to 18kHz.

"The rear jackplate features two 1/4 inch jacks wired in parallel, allowing for easy daisy-chaining from one speaker to another. Either jack can be used as an input or a through connection. The 3-position HF Horn switch allows for full high frequency output (0 setting), -6dB reduction of the highs (-6 setting) and Horn shutoff (off setting)."
