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.

Bazooka BTA6100 Subwoofer Enclosure Tube
Subwoofer enclosure tube gives vehicle owners an easy way to add a subwoofer to their audio setup. Like all subwoofers, the BTA6100 provides the bass, allowing listeners to scale back the bass on the other speakers, which means they can play them louder with less distortion.

Car for subwoofer

Universal Subwoofer Enclosure
The universal subwoofer enclosure provides the perfect box for a truck, fitting easily behind the vehicle seat. Otherwise, the box can also find use behind the back seat of a car. The Obcon Dual 12 offers a premium MDF build with a Tri-lock joint construction. It also utilizes the Labyrinth Power Port for greatly increased bass sound.

Car Subwoofer

Car Subwoofer, for all people is a big gadget what love in your car. If you have a vehicle, the audio system is stronger bass sound that many audio enthusiasts desire. But subwoofers need more than a low-range speaker to perform well. The enclosures they sit in can play a huge part in the subwoofer's sound. help separate the sound waves generated by the rear of the diaphragm on the speaker from that produced at the front of the speaker. Otherwise, the two sounds would create distortion, echo, and reverberation, ruining the listening experience.

So in your car can put this design:

1. Design of car subwoofer with dual chamber.

This style is designed and built for deep bass performance. Offering a dual chamber and shared slot port vent design, 5/8-inch MDF construction, making for a durable speaker. Simple to setup and easy to use, the enclosure provides a sturdy box constructed of quality materials.

2. Design of car subwoofer with screwed down terminal cups

From the provider of superior performance and sound engineering in enclosures, offers a quality 12-inch hatchback enclosure. Completely carpet enclosed, the box has screwed down terminal cups and MDF construction. The enclosure also has 1-inch speaker baffles to help control vibrations and ensure that listeners only hear what the speaker puts out, making for a cleaner sound.

TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 general description:

The TDA1566 is a car audio power amplifier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package. The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identification can be read with I2C-bus. The load identification detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load. The TDA1566 can be configured in a single BTL mode and drive a 1 Ω load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel.  TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 features:

• Operates in I2C-bus mode and non-I2C-bus mode
• TH version: four I2C-bus addresses controlled by two pins; J version: two I2C-busaddresses controlled by one pin
• Two 4 Ω or 2 Ω capable BTL channels or one 1 Ω capable BTL channel
• Low offset
• Pop free off/standby/mute/operating mode transitions
• Speaker fault detection
• Selectable gain (26 dB and 16 dB)
• In I2C-bus mode:
• DC load detection: open, short and speaker or line driver present
• AC load (tweeter) detection
• Programmable trigger levels for DC and AC load detection
• Per channel programmable gain (26 dB and 16 dB, selectable per channel)
• Selectable diagnostic levels for clip detection and thermal pre-warning
• Selectable information on the DIAG pin for clip information of each channelseparately and independent enabling of thermal-, offset- or load fault
• Independent short-circuit protection per channel
• Loss of ground and open VP safe
• All outputs short-circuit proof to VP, GND and across the load
• All pins short-circuit proof to ground
• Temperature controlled gain reduction at high junction temperatures
• Fault condition diagnosis per channel: short to ground, short to supply, shorted leadand speaker fault (wrongly connected)
• Low battery voltage detection
• TH version: pin compatible with the TDA8566TH1
