Active Subwoofer

High Power And Efficient Car Subwoofer

Car owners and manufactures often add the car subwoofers with the car Audio System to enhance their performance and to take them to a new level or sound excellence.  In fact the subwoofers are complete loudspeakers that are dedicated to reproducing bass audio frequencies.  The frequencies range from 150Hz to as low as 20Hz depending on the taste and requirements of the user. They are called subwoofers since they are used for augmenting the low frequency performances of any of the main speakers.

A unique feature of the subwoofers is that they are constructed by mounting woofers one on another and enclosing them inside well-braced cover that is either made of plastic or wood. They are available in multiple designs and are widely used to enhance the performance of the car stereos of any type.  Main designs are bass reflex, horn-loaded, band pass, and infinite battle types. Of course each of the types has its own pros and cons to deal with.

Broadly the subwoofers can be classified into two types.  One of them is the passive subwoofers and the other is active subwoofer.  Passive subwoofers consist of the subwoofer driver.  The enclosures will be powered by an external amplifier. On the other hand the active subwoofers have an inbuilt amplifier in the subwoofer. Way back in the 1960s the first subwoofer was developed for providing the addition of bass response to the home stereo systems.

Sensurruound was added during the 1970s. Compact discs and cassettes added further technological excellence to the subwoofers during the 1980s. DVDs arrived in the 1990s and with them came up the LFE or low frequency channels. That was the time when the subwoofers started gaining popularity for home videos and car stereos.  It turned out to be the universally accepted Sound Reinforcement system by the time the new millennium arrived on the scene.

Numerous qualitative subwoofers that are used for the car audio and stereos are available in the market today. Recently the Infinity Systems, one of the units of Harman International Industries announced their new line of subwoofers.  Many other leading brands and companies are following suit. Advantage of the modern day improved subwoofers is the industrial designs and the value price added to them. Today the subwoofers use large-roll surrounds, polypropylene cones as well as progressive spiders in them.  In result they have gained optimal control of the Sound System and made the bash Sound Effects free from distortions and also prevents sound from breaking down while delivered.  The progressive spider applies increased force with the cone travel approaching its limits.  In result the subwoofer gains much greater durability.  Large roll surroundings help the cone edge maximum suspension eliminating any rattling that travels up the edge. Polypropylene cone is stiff despite being lightweight and thus provides an excellent balance of efficiency with power handling.

Active vs passive subwoofer?

which is better for a Home Theater system?

I am looking at different systems and some have passive and some have active subwoofers.

I don't have an amp for the passive subwoofers if they should have one.

If I get a passive subwoofer system, would I have to get an amp for it to sound as good as an active subwoofer system?

it all depends on the power of your receiver. if you have a gargantuan reciever (200-300 watts/channel rms) then you probably do not need an active sub, but im guessing you havent spent 2-4 grand for one of these brutes ... so an active sub is probably in order.

also ... you have said nothing about the size of the room ... or where you plan on putting the sub ...which all factor in when selecting a particular size of sub ..and the power/frequency response of one as well.
