What is a sound bar woofer and function


A woofer is a device that producers low frequency bass sounds. Often in a form of Sub Woofer. Bass sounds are not directional. So once set up it will give the rumble and vibration needed to the sound system.

I have a JBL TLX CSS-SUB1 sub at the back are where you connect the speaker wires to the receiver but i don't know witch wire goes in what? i have no clue


The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.

Alesis M1 active 620 woofer problem


There clearly is a fault in the sub's amp section. It's probably the main part that does most of the work. It will need to be replaced.

I think I blew out the woofer...low frequency rumbling...is that something that can be easily switched out?


The woofer would only blow if it was overloaded with too much signal. The common cause of this connecting a speaker of lower power than the amp or ohms than it. The simple way to cut out rumble is at the amp by reducing the bass, however most amps will cut all the bass and not what you want. Another way is a filter designed to cutt bass or low sounds. However your best bet is to use a Graphic Equalizer to control the tone, most have a 31khz control which will cutt the rumble you describe, but keep the wanted bass sound.

Your D-SERIES amplifier was designed to operate efficiently at loads down to 2 Ohms.
This means that you can install four 8 Ohm speakers per channel when using parallel wiring.
of an additional 10W to each speaker.
Please note: The gain control of any car audio amplifier should not be mistaken for a volume
control. It is a sophisticated device, designed to match the output level of your audio source unit to
the input level of the amplifier . Do not adjust this input level to maximum unless your input level
requires it. Ignoring these instructions will result in an input overload to the amplifier, and excessive
2 Ohm Operation
front panel will be illuminated, indicating the amplifier has gone into a self-preservation mode.
these conditions before attempting to power up the amplifier again.
When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The
current draw will so increase by about the same amount, also be sure you have enough current to
run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be
distorted.
Increasing the number of woofers per channel at low frequencies (up to 100MHz) produces an acoustic
coupling effect. This acoustic coupling increases your power output by 3 dB per speaker, or the equivalent
audio distortion. It can also cause the protection circuit to engage.
