Our Bijoy Series Active subwoofers are the best choice for those, who want an accurate yet powerful bass at a reasonable price range. We introduced this model to fulfill the demand of our starter level audio enthusiasts who want a sub which can perform well for both music and movies within a limited budget of course. It has a very powerful 10” driver from LG electronics which is capable of driving 250 watt RMS and can reach as low as 28Hz efficiently which made this sub an ideal one for all purposes like movie, music and gaming etc.
Just connect our subwoofer with your AV receiver, TV, PC or any media to boost up the bass response and feel the actual sound which musician wanted you to feel. The Amplification: As large amount of power was needed to drive the sub we used powerful TDA7294 chip from ST electronics to power it up with its high power, low THD & high durability and protection capability. We used two of this 100 watt chip at Bridge tied load to get the maximum power and shake this baby at its full. The chip itself has some good protection circuitry and stable power handling capability which made the subwoofer a durable one yet powerful one.
Cabinet Design: We also tried to bring maximum efficiency and accuracy while designing the sub cabinet. We tuned it at 30Hz which is very much musical and can also meet your movie needs by going as low as 28Hz. The ported/Bass reflex design gave us maximum output level at the given power and given the ability to reach the deepest possible bass frequencies without compromising the loudness much. As the amp has to deliver huge power driving the sub, it also gets too hot while running at highest level, so we had to take care of the hit issue and our cabinet design gave us the opportunity to emit the hit through the port. Because of our intelligent design we made it possible to run the sub continuously 24hours at highest level without any sort of problem.
Connectivity and Control: We made the connectivity as simple as connecting a headphone into your mobile phone, the difference is you just have to give a power source in it. We gave multiple RCA socket for line level input. You can either use a stereo source or LFE/mono source to play the sub and either case you will get a filtered low pass out. For better matching with your speaker, surrounding or environment, room size and your taste of music; we gave an active crossover controller which will allow you to pass 80Hz to 200Hz by turning a simple knob. A volume or level controller knob is also there to match the bass level to your speakers. We gave standard IEC socket for AC power in which you can switch easily if you wish to.
Protection and safety: In designing a powered subwoofer particular attention must be reserved to the circuits devoted to protection of the device from short circuit or overload conditions. The chip we used in the circuit has come up with some protection features which automatically control itself from extreme condition and keep the circuit safe and protected.
All at once our driver choice, amplification system, cabinet design, acoustic treatment inside the sub, its well bracing and shielding, the outlook and our after selling service everything made it possible to compete this sub with any other renowned brands in HiFi audio field. And we are proud to introduce something like this and build it by our own in Bangladesh.
