Description

A pair of LS1s stereo subwoofers integrate seamlessly with the LS1 or LS1a to make a uniquely phase-coherent three-way system.

Although the LS1 on its own can play down to 40 Hz with quite impressive power, the bottom octave down to 20 Hz is hard to reproduce with a two-way loudspeaker system. A dedicated driver for frequencies below 70 Hz solves this. The low system distortion offered by the LS1s will appeal to those who like to listen at higher sound levels and to those who are in search of low distortion in general. As a bonus, the LS1s sub can be taken off the footplate and placed in the optimum position for low-frequency reproduction, which is not necessarily also the optimum spot for the main loudspeakers. The LS1s is based upon a very high-quality Peerless woofer and a 500W Hypex amplifier.

• Linear response down to 20 Hz
• Turns the LS1 into a powerful 3-way system
• DSP-controlled frequency curve
• Phase-corrected crossover at 70 Hz
• Peerless woofer and 400W class D amplifier
• Mains outlet for LS1 minimizes cable clutter

A pair of LS1s stereo subwoofers integrate seamlessly with the LS1 or LS1a. Its phase-corrected crossover at 70 Hz is already built in the LS1, so just adding the subs turns the system into a unique phase-coherent three-way system.

Although the LS1 on its own can play down to 40 Hz with quite impressive power, the bottom octave down to 20 Hz is hard to produce with a two-way loudspeaker system. Classical music especially does benefit from a balanced reproduction of these ultra-low frequencies. Also, professionals who need to check their mix at raised SPL will value the lower LS1 system distortion offered by the LS1s option.

“Adding the LS1s subs turns the LS1 system into a unique phase coherent three-way system.”

At low frequencies, wavelengths are so large that the speaker’s orientation does not matter. This fact offered us the opportunity to elegantly fit the LS1s between the legs of an LS1, facing upwards. As a bonus, the LS1s can be taken off the footplate and placed in the optimum position for low-frequency reproduction, which is not necessarily the ideal spot for the main loudspeakers. To match the immaculate quality of the LS1, Grimm Audio selected a top-notch Peerless woofer and a 400W class D amplifier of Hypex fame.
