A Final Swing around Jupiter's Rings While few people want to experience a natural seismic event up close and personal, having the Earthquake SuperNova MKIV-15 subwoofer in my home theater was an exciting but safe way to make the earth move. Even in my large room, a single SuperNova was able to put out enough low-bass energy for the most bombastic scenes of mayhem and cosmic destruction. More austere films, too, benefited from the MKIV's nimbleness and finesse. Even music's harmonic foundation gained solidity and presence. If you've priced the most expensive state-of-the-art subs, you could almost buy two MKIVs and still come out ahead. But you shouldn't need more than one. There might be better subwoofers on the planet, but I haven't heard them. I heartily recommend the Earthquake SuperNova MKIV-15 for any system requiring the ultimate sonic boon.

Driven by test signals in my large home-theater room, the SuperNova produced audible bass as low as 15Hz. More remarkably, there was no apparent 30Hz doubling. No other subwoofer I've used, including the earlier SuperNova MKII, could even begin to produce 15Hz tones cleanly. Of course, one doesn't hear 15Hz as much as feel it. My room sure felt it—hanging pictures and doors rattled and shook. The Earthquake MKIV-15 did 15Hz with panache and style. Only the passive woofer's extreme excursion hinted at how hard it had to work to put out this subterranean tone. From my listening seat, it just felt like magic. At more common frequencies, between 20 and 40Hz, the SuperNova was as clean as a freshly washed white tablecloth, and as accurate as a newly graduated aerospace engineer. Whatever the material—full-scale orchestral recordings, small-ensemble jazz, blockbuster movie soundtracks—the MKIV performed with aplomb. To take full advantage of the sub's apparent speed and control, I changed my system's crossover point from 50Hz to 60Hz. Even though my Dunlavy SC-VIs have two 15-inch drivers apiece, the overall low-bass response in my room improved when more of the low-bass duties were shifted onto the SuperNova's shoulders. Bass transients became a bit cleaner and better defined, while the midbass lost some excess bloom and congestion.

On the Bench THD measurements were made with our calibrated microphone placed 15" from the active driver. I was able to achieve a maximum SPL of 120 dB at 1 meter, using a combination of 20 Hz, 31.5 Hz, and 50 Hz sine waves. At 15 Hz, THD+N was almost 20%. Part of the reason for this, is that the passive radiator is doing most of the work below 20 Hz. The active driver has an Fs (free air resonance) of 26 Hz.

clik on link above on review test shows all specks in test how performed i just own it i dont work for them in anyway just lov helping pp 98 bd at 17hertz

Conclusions I guess it was worth the wait for an Earthquake SuperNova MK-V, because I loved it. This subwoofer plays loud, deep, and clean. It's reasonably priced if you get the polyurethane finish. You can't ask for anything more than that. At 25 Hz, THD+N was now down to less than 2.5%, a superb number for such high output.

We have a pretty big listening space in the lab, and plenty of wall and corner treatments, but the MK-V managed to fill it to the brim with thunderous sound. From Tchaikovsky's 1812 Overture, to Stravinsky's The Firebird, there was nothing that made the SuperNova flinch. There is nothing like a big high-excursion driver coupled with lots of watts. With music, it is easier to detect harmonics, because it makes instruments such as string bass sound abnormal. However, I could detect no harmonics even at high listening levels. With movies, ah what a sound! From Matrix: Revolutions, to Pearl Harbor, the room shuddered with wonderful deep bass. Although one SuperNova is plenty, there is still some advantage to having stereo subs. Not all SSPs have stereo subwoofer outputs, but some do, such as the Lexicon MC-12 and Theta Casablanca III. The Burl Wood SuperNova is beautiful, but very expensive. So, if I were populating my system with the SuperNova, I would get two of the Black Polyurethane versions, which together are almost the same price as one Burl Wood version

Introduction I have been wanting to review an Earthquake Subwoofer ever since I saw someone standing on one at CES, getting an 18 Hz massage. Not only was he shaking, but everyone's clothing nearby. I suppose the adjacent booths didn't like it, but I know all the passersby did. Joseph Sahyoun and John Paul Lefebvre dropped a SuperNova MK-V (the previous version was the MK-IV) off at our test facility last month for me to try out. It is big and heavy, as all good subwoofers are. In this case, all 88 pounds of it, with two 15" drivers (one active, one passive) and a 580 watt digital amplifier. http://www.hometheaterhifi.com/volume_11_4/earthquake-supernova-mkv-subwoofer-10-2004.html read review bigge rpics
