| JL HD750/1 Monoblock |
This ultra-compact monoblock amplifier
employs Single-Cycle Control switching design and R.I.P.S.
technology to deliver 750 W of clean power into any impedance between
1.5 and 4 Ω, giving you the highest degree of flexibility in designing
your subwoofer system. Tight power supply regulation keeps distortion
down and maximizes your bass quality. From a pure sound quality
perspective, we invite you to compare the real-world, in-car performance
of this amplifier to any other amplifier on the market, of any type,
at any price.
This ultra small monoblock very recomended to drive your JL W7 subwoofer, not to worry with it's small size, it has lots of power to punch your subwoofer to its maksimum spl, tested with pairs of JL W7 Subs and it's sound just great without any signs of debilitation.
While targeted primarily to subwoofer
applications, the HD750/1 is a full-range amplifier and can also be
used to drive high-performance mid and high frequency speaker systems.
This amplifier features a brushed
aluminum finish with black powder-coated cast alloy heat sinks and
bottom panel. A black powder-coated, gasketed cover is also provided to
protect the controls.
