Dear Genelec tech guys,

I am setting up a home studio in a farily small room H:242 cm L:329cm W:261 (however there is a slightly wider section of the room at the front, by the door

After getting some bass traps and treating the reflection points etc, The 8030a speakers were sounding very nice. After adding the sub with 0 adjustments on phase/volume etc i am having some problems trying to find the best spot.

I did try putting the sub on the lower shelf (next to the floor) of my desk, but have been advised against this due to sympathetic resonance (i could feel the bass resonating through the desk quite clearly). To be honest it sounded pretty good in this position, powerful (maybe too loud actually) and tight. As i cant put the sub there it limits positions in the room as i have quite a small room to use

Currently, the sub is placed on the right wall under 60 cm away from the wall (as per manual) and with the same distance between speakers and me, to hopefully stop phase problems.

In this position the bass doesn't sound particularly good to me. Not very tight, genre ally not that clear and a very audible boost around 125 Hz (i have the strongest room mode or whatever you call it there).

Any suggestions for this problem? What is the best place to put it? Maybe i need more traps?

thanks for your help

Hi Kris,

In a small room and in near field configuration, the subwoofer needs to be somewhere close to you and also close to the main speakers in order to have good bass. So the area under the desk looks quite optimal. You said you already tried putting it there but it was too loud and resonated the table. The first thing is easy to cure because the subwoofer has a level adjustment. Turn it counter-clockwise to make the subwoofer sound quieter. The second problem may be reduced after you adjust the level but you can also try some soft rubber pads/mat under the subwoofer, so that the MDF end plates are not directly in contact with the shelf.

Hi Ikka

Thanks for your reply. Funnily enough i put the sub back under the desk last night, it sounds much better, In the other position the sub was causing the radiator to resonate anyway!

Do you have any tips for bass roll off, phase settings or any other configuration please? I have a mic suitable for room testing if that helps - i am very keen to get the best settings possible

would a monitor vibro pad be suitable for the sub?

Have you checked out the operating manual for the 7050B? There we provide information about setting up the roll-off and phase.

Monitor vibro pad would quite probably be suitable. You can always test and see how effective it is.
