Fostex PM-SUBmini 2

Bought for use with Eve Audio SC203 monitoring system. Despite overwhelmingly positive reviews i remained sceptical it would please me as a bottom end for casual listening and monitoring sound. Pleased to say this is a tremendous value for money unit - £130 vs £460 for the Eve TS107.

While i don't have direct comparison to more expensive studio grade subs as a casual listener/producer it is more than enough. Has a clean, punchy bass response which perfectly suits smaller monitoring systems such as Eve SC203. Without it I was missing a lot of low end, SC203 has surprising bass but little impact. Upon firing up the SUBmini sound immediately became much fuller. In my situation it sounds best with phase inverted (brings a warmer, bassier response) and volume around half way, though your mileage may vary.

So to conclude this is perfect for smaller monitoring set-ups where super deep lows and loud listening volumes are not a requirement. Clean sound and very well made unit for the money.

My requirement was to pair a sub with the PM04 Fostex monitors. The SUBmini2 handles the job very well. The bass is tight and sounds precise, no more power is needed for desktop monitoring, and the controls are unmatched for the price range. The frequency cut-off works fine, and you also get a phase inversion switch and a volume level control. The auto-standby feature is also very useful, in that it does not affect the connected monitors i.e. no popping sound is transmitted to them, and its sensitivity is enough to keep the sub on in relatively low volume levels.
As drawbacks, I may note the lack of balanced input/output connections, and the bright blue light when the sub is on, which may annoy some if placed on eye level.
In total, I'd recommend the subwoofer to pair small studio monitors and limited studio space, thanks to its plentiful and well-implemented features and sound quality for its price range.

This small subwoofer delivers not a big amount of bass, but because it is not ported the clarity of the sound is very good, even considering it small size. I compared to a 8 inch Mackie (around 300 euros), and even though the Mackie would make some stuff shake in my room, it wouldnt sound as clear. My room is around 17 square meters.

I have it paired with some Presonus 3.5in monitors (for 129 Euros) and the combination works PERFECTLY. Visually, the presonus have composite cones which also fit very well with the Fostex cone.
Compared to the previously mentioned Mackie, this subwoofer would not send any noise to the Eris speakers, while the Mackie did, EVEN when it was turned off. So thumbs up for the Fostex.

The only complain I have about the subwoofer is that it only has a unbalanced RCA input and does not offer a 6.3mm jack balanced, which is pretty much standard.

Anyway, for the price I paid, and for the amount of space it takes, I dont think you can do better.
