Kurlo subwoofer

In awarding it Subwoofer of the Year 2004 Hi-Fi and Home Theatre Consumer Buying Guide 2004 said: "My first impressions were immediate. From the very first note it played, even before adjusting any of the controls - it was obviously very clean and tight. Very few subs start making an impression so early. ..... The Kurlo 3 is a great music subwoofer and a great movie sub for those with less than enormous rooms. If you like loud action movies and have a big room you can always buy two. This is one of the cleanest, tightest and most musical subs 1 have heard. It goes very deep for its size and price and is well built. The marketplace is well served by 'me too' loud trashy sounding subs that don’t play very deep or sound very nice. The Kurlo 3 is most definitely not in this camp. "

"Wow - this was as clean a presentation of this piece as I have ever heard from a subwoofer at any price! There was no overhang after the transient - it stopped just as quickly as it started. The Kurlo 3 has great rhythm and pace, and its virtues of cleanliness and tightness of reproduction served themselves very well and led me to the conclusion ...... that this is a fantastic music subwoofer. ..... (And) all its virtues described above carried on into movie watching. "

"The Kurlo subwoofer is a delight, handling subtleties as well as it handles explosions."
Sydney Morning Herald "the guide" Oct 22-28 2001

"In fact I could not criticise any aspect of bass performance. It was extremely smooth, powerful, well-extended and tight ....what more could you want". Australian HiFi May 2000

Legend's Kurlo subwoofers add powerful, deep yet tightly controlled bass to any home theatre system producing extra excitement and drama for the enjoyment of your movies. They combine especially well with the famous fast open sound other Legend loudspeakers in our home theatre systems. The Kurlos can be placed in a corner or near a wall where they will 'disappear' because of their profile.

Like the Kurlo 3, the Kurlo 4 uses a 12" (30cm) extra-long throw XLS bass-driver. It has a very large voice-coil and huge 3 Kg magnet to allow a cone excursion of 44 mm. This makes it equivalent to a 15-18" unit having a normal excursion of 6-8mm and so the bass driver will reproduce the loudest, deepest sounds and musical notes with superb ease. With the Kurlo 4 we have increased the built-in power to 400W peak (250W rms) with huge current supply giving massive reserves of power for the long-throw drive unit. It can be connected either directly to your processor or pre-amp (at line level) or to a pair of speaker outputs from your main amplifier. It also has variable volume and upper frequency control, which can be bypassed for direct home-theatre receiver control ; phase control; and optional automatic power-up mode.

The Kurlo has a sealed cabinet to improve speed and transient response. However we have also added a small amount of electronic equalisation so that the frequency response is flat to nearly 20 Hz below which it has been rolled of rapidly to avoid cone damage. At the top end, the frequency response can be rolled off from 40 - 160 Hz at -12 dB/octave. For the measurements shown below, it has been set at 60Hz.

The Kurlo's cabinets are very solidly built to minimise secondary vibrations that can muddle the sound. We use 25mm MDF veneered on both sides with Australian wood on the side and back panel and 40 mm of MDF on the front panel. In addition to giving a superb furniture finish, MDF has high strength and excellent damping. Cabinet strength is further increased by extensive asymmetric bracing; and damping is increased by addition of constrained-layer damping. Sound waves inside the cabinet are dispersed by a proprietary technique and absorbed by Australian wool.
