Genelec 7040 APM

On various forums I read that Genelec sub woofers are over priced and that similar or better results can be achieved with some sub woofers from hi-fi audio market, at a lower cost. I decided to take the risk and try my luck with 7040. This was my sixth sub woofer and with previous five I was never able to achieve proper balance between the main speakers and the sub. There was always some boominess of the lower end and the bass was either bloated or not present. My room is not treated and the only spot the sub could go was right in the corner, next to the right main speaker. I followed Genelec's recommendations and adjusted the dip switches for the in corner position and the magic happened! I had to play with the volume a bit but it was a different, well balanced kind of a sound!
I was a bit skeptical about letting the sub restrict what goes to the main speakers (nothing under 85 Hz) but that actually improved the sound of the main speakers. They sound more open and relaxed. Another benefit is that bass is present regardless of the sound level you are listening at. Sub is not affecting the sound level sent to it, so you don't have to play it loud in order to activate the sub. Some people may not find the specs too impressive but I was not looking for -3 dB at 20 Hz since I am living in an apartment building and that would not be the most pleasant experience for the people living above and below us. The sound I am getting is very clear and musical. I am very happy with my choice!
If there is an area of criticism, the sub does not have any protective feet at the bottom of it so it will be scratched if placed on the hard surface.

As expected this sub works excellently with 8010A and 8020B.
Nicely controlled, very clean, well balanced and more powerful than its specs would suggest.
The super broad range of sensitivity control and internal high pass filter mean it works well with all manner of non-Genelec powered monitors. Just order the correct cables because connections are XLR only.
I was surprised how much the sub adds with somewhat larger speakers such as Mackie HR624Mk2, provided you accept the sub's power limitations.
Auto-power off/on works well.
DIP-based adjustments are adequate and easy to configure, but not something you'd want to fiddle with every day because of their location.
The setup is used for critical listening to music rather than movie/nightclub use. This sub won't loosen your teeth, but provides precision bass reinforcement for smaller boxed speakers.

I am buying this to accompany my pair of 8030C bought half a year ago for the low end extension.

My room is tiny measuring ~ 2m*3m with a wardrobe making the listening space 1m away from speakers and sub, I opt for the 7040 since it's the only quality sub with highpass filter which fits and don't take up my leg room.

At first I was a bit worried it won't be powerful enough being a 6.5" driver in tiny package, ended up it's a perfect match, with the sensitivity knob matching the Genelec monitors for seamless cross over, and dip switches very easy to make them either having flat bass down to 30hz and hearable at 25hz, or to make it slightly bass elevated by 2db as in preference curve, this is the best purchase decision in my audio journey, now I have almost full 20-20khz sound which is very smooth, can't recommend it more in any space limited rooms
