Who is janFIN? Before I start writing I feel the need to introduce myself to you: I am a music/movie enthusiast who lives in Helsinki, Finland. Hometheater has been my hobby for a few years now. Like everyone else I struggle to find the equipment worthy of playing my source material. Sometimes it gets so bad that I feel the equipment is more of a hobby than the material I reproduce with it. I'm almost happy with my current system and I feel that I can actually enjoy the music and movies without getting distracted by the quality of the equipment. Here are the main elements of my audio system: Amplifier: Cambridge Audio Azur 540R DVD player: BBK DV 971 Main speakers: Tannoy Sensys DC1 Rear speakers: Tannoy Fusion1 Subwoofer: SVS PC-Ultra EQ:d with Behringer Feedback Destroyer Pro DSP1124 Onwards to the actual review... My time with the Gemini was limited and I had alot to do the weekend I tested it so I have to keep it short. How does it look like? The first impression was rather funny, how cute and small can a subwoofer be? Don't be fooled, it has a very good finish and looks rather serious instead of funny, but it is VERY small! I took a few pictures to show the size related to a few things you might be familiar with: Gemini and Tannoy Fusion2 Gemini and PC-Ultra Gemini in front of PC-Ultra The pictures don't do justice to the small size, but they do show the good finish. The pictures probably made you wonder about those displays on the amplifier. It has separate lowpass filters and gain controls for both low and high level inputs. The high level input has a lowpass adjustment range of 30-120hz and the low level input crossover is 30-120hz/LFE. The amplifier is rated at 150W and there are leds to tell you how much of that you are using. The power usage leds are between the crossover displays. Here is a picture of the 8" driver: I used my BFD and TrueRTA for calibration and the FR looked like this: Large version The yellow, violet and green curves is the subwoofer at different levels. The turquoise is with the main speakers and the orange one is background noise. My listening room has a huge gain at 20hz so the FR looks good. These measurements where done with only one -7dB filter at 55hz on the BFD and are not comparable to anything. I just wanted to show them because I like measurements... I also did some THD measurements in room at 50cm distance: 20hz was too distorted to be measured. 25hz 87dB 10% 32hz 95dB 7,5% 50hz 105dB 7,5% 63hz 110dB 2,7% How does it sound? I listen to many different artists like Genesis, The Police, Pink Floyd, Madonna, Metallica, Limp Bizkit... and my girlfriend is a technomaniac, so I had to try out that too. Genesis and The Police are easy on the subwoofer, but they tend to point out the subwoofer if it has difficulties to keep up. I got the feeling of larger mains while still keeping the bass tones transparent. It could play harder than my ears would take with this music. Pink Floyd has some very low notes. The first track on "Dark side of the moon" is good to test the extension of subwoofers. The thumps in the beginning go as low as 25hz with great intensity. At normal listening levels it sounded natural and even shook my room. Trying play it really loud made it sound muffled and like it was choking. Metallica and Limp Bizkit have a lot of bass guitar and drums involved. Still nothing to complain about at normal listening levels. Bass guitar tones are easily distinguished from each other. Even very fast drumbeats sound like separate beats. When trying to wake up the neighbors the sound became monotonous and loose. At around 50hz it has enough output to play almost any basic techno song at levels that make my head ache very fast. The beats sounded snappy, just like with my PC-Ultra. I also watched Monsters Inc (I just love that Boo... ). The Gemini added some feeling to the movie, but most of the real room shaking effect were unnoticeable. Not much more to tell about that. Conclusion The thought of testing sub that's smaller than the XLS200 was wierd, but it didn't take long for me to understand what it's all about. It is obvious that the Gemini is made for the WAF market and for music lovers. It has enough power for it's purpose and tonal qualities very close to the Monolith. With music it had no problems playing even the lowest bass in music at normal listening levels (my RS SPL meter needle is around 75-85dB normally) in my room. This could be a good choice if you are going to use two subs in stereo. If you like ground shaking and room pressurizing bass you should add a lot of money and buy something larger. I will gladly answer to questions if I have the answers.
