Default Subwoofer 18L FAST pulse compensation

Hello everyone !,

How should i start ?
First I will tell you something about my first own speaker.
I want to build a f.a.s.t acitve (minidsp)speaker for my desktop.

-Size something like 35x35x35 in the end it has to be a cube.
Design ? I want the full range speaker alone in the front.
I am not sure yet about the full range speaker neither do i know the x0.
What would you recommend ? I know that we cant locate lower frequencys, but what does make sense for a bass speaker on a side of a loudspeaker ?
-budget: around 100 Euro per side.
-I like to listen loud and i love good,hard bass.
-I was thinking of a pulse compensation Subwoofer, so it wont shake on the desk ?

a glance:
-Subwoofer for FAST
-100 Euro
-with a lot of power
-active with minidsp
-pulse compensation ???

AMP: -6 x 100Watt Class-D Audio Amplifier Board – TDA7498
~500 Watt Power supply

My thoughts: 2x w5-1138 per speaker.
2x reckhorn d-165 (my favorite)
mds 06
aw104 (to big???)

That is all which i know and i cant decidee which one is the best for my project.

Sry for my bad english !
But i hope everyhing is clear.

You mean opposed motion force canceling subs? There are several push pull slot loaded sub designs around with 8in drivers. I have designed several. Use the miniDSP 2.1 plugin. A couple of class D amps and you don't need anywhere near 500w! Maybe 30 or 40 max for desktop use.
