Subwoofer

What is a subwoofer? Is a dedicated low-frequency speaker cabinet, usually self-amplified, that fills in

Subwoofer
the deep, rich bass that is missing from most main speakers. Subwoofers are specialized, and don't reproduce midrange or high frequencies. Most main speakers are passive (unamplified).  Subwoofers usually handle frequencies below 150 Hz or so. 

A quality subwoofer not only reproduces the thrilling deep bass notes with authority. Its presence in the system also allows the receiver / amplifier to reproduce mid-bass and mid-range notes more cleanly. All kinds of instruments, including voices, can be heard more clearly. Why should you add at least one great subwoofer to your system? 

1. Deep bass adds the emotion, the physical feeling of presence and excitement, to a good music or movie performance! One reason that inexpensive speakers sound "just OK" is that they cannot reproduce deep bass very well. 

2. Subwoofers help solve problems in speaker set-up and placement. It's difficult to set the main speakers where they are able to provide realistic imaging, and set them in the best place for bass.  In-wall and in-ceiling speakers can be placed where they work best cosmetically, without concern for their bass reproducing ability, when the system has at least one great subwoofer. 

3. High-quality subwoofers are engineered to generate the massive cone movement required by low bass reproduction. A good subwoofer is specifically designed to generate deep bass. Whether you like jazz, classical, pop or rock, a good system can be made better with a good subwoofer.

200W Hybrid Audio Amplifier Circuit

200W Hybrid Audio Amplifier Circuit - c onnecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors. TDA 2030 is produced by SGS Ates and is a complete audio amplifier. AB class of the final amplifier cand deliver up to 14W on 4 ohm at a +-14V power supply. With a proper designed power supply this audio amplifier can output 200W. Active components: IC1, Ic2 TDA 2030 T1, T3 = BD 250, TIP 36 T2,T4 = BD 249, TIP 35 D1 … D4 = 1N4001 200W Hybrid Audio Amplifier Circuit
