Does anyone have any thoughts on doing this, im thinking a 2-3 litre sealed enclosure, it wont get below 80hz, but ill build a little sub with the 8inch tang.
Anyone know of an Oz distributor?
Where can i find a cheap amp designed for computer use in Oz?
thanks guys

Have a look at ESP. (http://sound.westhost.com ) Apart from being an informative read in general, his kits are highly regarded and he has numerous articles relevant to your situation.
What I suggest is using chip amps with line level crossovers where possible(2nd order passive line level high pass http://www.t-linespeakers.org/tech/filters/passiveHLxo.html and 4th order active lowpass) Using small drivers FR with a 2nd order butterworth highpass network at the –3db point (sealed box with Qtc of 0.707 (Butterworth alignment) of the FR will give you 4th order Linkwitz Riley alignment. The lowpass can then be constructed either with a simple opamp buffer to sum the two channels followed by a 4th order Linkwitz Riley highpass section as per ESP. This should give you an acoustical 4th order crossover with minimal investment in components for the electronics.

Be careful using phase plug speaker drivers. There is a tiny gap between the cone and the phase plug.
Tripath Trio amplifer fits in a expansion planel. It puts out about 10 watts per channel.
I was thinking of using three TANG BAND W3-881S per channel. Then add a three way series filter to optimize the frequency response.
Parts Express are now carrying Tang Bang speaker drivers.
