Cheap upgrade needed

[Nickiboy]

Hi.

I am looking at adding a sub to my current system, it is only used for music. I mainly listen to techno. The current system is:

Macbook

Aune T1 (Next to be upgraded)

Perreaux SM3

Genelec 8030A

I have been originally looking at the Richter Thor. However I am thinking maybe a smaller better quality sub will be better.

I was also hoping the sub has audio out, so it will be connected to the preamp. And the monitors to the sub. Or is there a better way of doing this?

As I'm buying second hand, I'm looking for something that I can buy for a few hundred.

The room it is filling is approx 5x5.

Cheers

Search on "subwoofer" in the classifieds.  There's a few there at the moment.
