Our OS-15 sub designed for  customers with larger rooms and those who want greater bass impact  specifically. Our OS-15 sub offer two advantages when compared to our other subs. The first is 2 dB higher output. At bass frequencies, every 6 to 10 dB increase sounds twice as loud (the actual number varies with listeners). So the 2 dB increase with our OS-15 sub will sound around one third louder. The second benefit is an increase in perceived authority and impact. When a subwoofer amplifier reaches it's limits, clipping occurs. This tends to reduce the dynamics and authority of the sound. Our OS-15 sub can play cleanly where our other sub are operating at their limits. The difference is felt as much as it is heard.
Include our CORE TECH sub                                                    
For audiophiles who want something more, we proudly introduce our Signature Edition subwoofers. They are instantly recognizable as a very serious high end product. Elegantly finished in Vintage Brush black .Finish.
For audiophiles looking for uncompromising accuracy in an elegant package, our OS-15 Signature Edition subwoofer is the ultimate choice. As an audiophile you appreciate that bass is the foundation of a satisfying music or home theatre experience. You also appreciate that there is more to a home theatre subwoofer than shaking the room, and that music can be far more satisfying with a subwoofer that can play deep.
