LS1s
Loudspeakers
A pair of LS1s stereo subwoofers integrate seamlessly with the LS1. Its phase corrected crossover at 70 Hz is already build 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. Especially classical music does benefit from a balanced reproduction of these ultra low frequencies. Also, people who like to listen at raised volume once in a while 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, wave lengths 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, that is not necessarily the ideal spot for the main loudspeakers. To match the immaculate quality of the LS1, we selected a top notch Peerless woofer and a 400W class D amplifier of Hypex fame.

You must hear that! Absolutely!
Fritz Fey, Studio Magazin, Oberhausen (LS1be)
Total peace of mind
Marja Vanderloo & Henk Boot, 6Moons (LS1be)
These dmf subs are insane! It took me 30 seconds to decide I had to buy them. Authoritative, open, tight, life-like, in one word: wow!
Wessel Oltheten, Spoor 14, Boxtel (LS1s-dmf)
The LS1be has a very beautiful low end, that not only goes to great depth, but is of exceptional pureness.
Marnix Bosman, HVT magazine, Nijmegen (LS1be)
Truly, this could be the last system you'll ever buy; an endgame solution.
Marja Vanderloo & Henk Boot, 6Moons (LS1be)
The system (...) is the equal of systems of hundred thousands of Euros when it comes to aspects like neutrality, purity and naturalness of tone.
Clemens Wergin, Die Welt, Berlin (LS1)
One for all and everything.
Fritz Fey, Studio Magazin, Oberhausen (LS1)
You will have to go to great lengths to find something that matches this sound quality for the same price.
Roy Ervin Solstad, Stereo+, Oslo (LS1)
Their natural sound and their unimposing, deep trueness kept overwhelming me and my colleagues.
Bernhard Rietschel, Editor in Chief of AUDIO, Stuttgart (LS1)
This is a speaker that sets a reference level and everybody should hear it, regardless of whether he intends to buy it or not !
Dimitris Stamatakos, AVMentor, Athens (LS1)
I've played everything from Rammstein to chamber music on these speakers, and they eat everything raw.
Roy Ervin Solstad, Stereo+, Oslo (LS1)
These are the most immersive, dynamic, detail-rich, nuanced, elegant, engaging, emotional, and yes, musical speakers I have ever heard. By far.
Timothy Roth, Positive Feedback (LS1)
I had that feeling of an open window into sound, across a wide range of music styles.
Nigel Palmer, Audio Media, London (LS1)
This is the most exciting, strange, beautiful, ridiculously convenient piece of non-audiophile audiophile gear I have seen or heard. These things are a bit science fiction really.
Bogdan Roscic, President Sony Classical, Berlin (LS1)
The naturalness of the LS1 turns me on big time.
Wolfram Eifert, AUDIOphile, Stuttgart (LS1)
The LS1's frequency response is unusually flat - indeed the flattest we've ever measured.
Keith Howard, Hi-Fi News, Croydon (LS1)
This is probably the most 'correct' loudspeaker I've ever laid ears on. The combined honesty, neutrality and pleasing musicality is at a level that I haven't come across before.
Christian Rechenbach, EinsNull magazin, Duisburg (LS1)
The LS1 seems to be a melting pot for all your expertises. I just find it fascinating. I am quite certain that the LS1 is at least the very very best 'value' in the market right now.
Wai-Shan Lam, hifi enthusiast, Hong Kong (LS1)
I’m afraid my english isn’t good enough to describe the overwhelming feeling while listening to music, reproduced by the LS1.
Ulrich Watermann, Berlin (LS1)
After all these years I finally have a standard on which I can rely.
Al Pryor, Mack Avenue records, Hempstead (LS1)
If someone came up with the idea to call the LS1 the best speakers he's ever heard, I would join in with a smile.

My audition of the LS1 was a transformative experience.
George Massenburg, McGill University, Montreal (LS1)
The LS1 is by far the best speaker that AUDIO had the pleasure of reviewing in over 35 years; this especially in the two crucial audiophile disciplines of neutrality and detail reproduction.
