Hello, I'm a newbie!
Does anyone have the solution to my problem..
<pre>

++==++= = = = = = = = = = = ++
|| ||
speaker A || ||
+----------++-----------+ +---------++-------+
| small active speaker | | single channel |
+-----------------------+ | 5.25" driver |
/ L \ / R \ | amplified |
/_____\ /_____\ |? How to make ?|
|? this speaker ?|
|? to a subwoofer ?|
+------------------+
speaker B
</pre>

Is it possible to turn "speaker B" into a subwoofer?
If so, how?
If it's not possible, I think "speaker B" here can be used as a bass extender from pc's output, but I don't have a clue how?
Anyone can help?

thanks

all you need to do is build a small amp (max 50w i'd think...) and a mono summerizer and a low-pass x-over. All of these projects are very clearly illustrated at Rod Elliots ESP site, http://www.sound.au.com. The mono summe ris on the front-end of the 300w sub amp project. good luck trying to get decent bass from a 5.25"!
