La Grande Castine speakers are exceptionally horny

Ultra high efficiency horn speakers are prized by some audiophiles for their ability to make a ten watt tube amplifier sound like 100 watts, but most tend to use conventional woofers, because a horn loaded woofer needs to be ridiculously huge to deliver good bass.

This trivial detail hasn't put off the makers of La Grande Castine, from a new French company called Musique Concrete. All three of this huge speaker's drivers are horn loaded, resulting in efficiency that's high enough to blow you out of the room with about three watts. Additional information is a bit thin on the ground, but expect these big boys to run around $100,000 a pair.
