Polk audio

I bought a Polk psw10 subwoofer and Polk t15 bookshelf speakers think I could connect the speakers to the powered subwoofer and be done. But no sound come from the speakers at all, but the subwoofer has some sound. Do I need a receiver for them?

Re: Polk audio

I love Polk Audio Speakers.  

 

Powered Subwoofer simply means the subwoofer supplies it's own power and only needs a signal from the receiver which is going to be a very low current signal

 

Most receivers do not send power to a subwoofer.  Subwoofers tend to use a lot of power.

 

Most speakers do not have a power supply.  They are powered through the speaker wire from the receiver/amplifier.

 

In order to get sound for your speakers you need to connect it to a receiver. 

 

Question, if you do not have a receiver what is your sound source going to your woofer

I just pluged it in to my tv's headphone jack with a 3.5 to rca cable. I'll buy a receiver and do it properly.

Re: Polk audio

I'm just learning about this. Any suggestions on receiver/amplifier? Do most work with any speaker?

Re: Polk audio

In a typical home theater installation you have 

 

TV  Typically most TV's have speakers and produce their own sound. Inside the TV is an amplifier that sends a powered signal to the TV speakers.  

 

Receiver, the words receiver and amplifier can be interchanged and quite often are.  Essentially the same thing. But a receiver is built to accommodate a number of inputs.  An amplifier simply supplies power to the receivers outputs and is inside a receiver (typically) 

     If you want surround sound or simply more sound you have options

 

It call all be called Home Theater.

Basic.  Two speaks or Two speaker and a sub woofer.

Less basic.  You can get systems that quite a few speakers. 

 

You hook your TV audio out to the Receiver input.  Your receiver will have at a minimum 2 outputs.  Left and right speakers. Most receivers (that are referred to as home theater) you can but today will support 5 speakers and a subwoofer or more. You will see things like 5.1, 7.1, 9.1.  The first number is the number of speakers you can attach and the second is the number of subwoofers you can attach. 

 

 

I would suggest going into the store and looking at the open box area.  I purchased a Yamaha receiver last fall for my secondary TV.  I was able to get a receiver originally priced at $450 for $79
