60 or below.. real simple..
For me it's more like 30, 40hz and below..
In other words, NOT MUCH!!!

Role of sub woofers?
I had begun thinking about changing out the KEF Reference 1s for floor standers, something like Wilson Sophias, Revel Ultima Studios, or the expensive KEF Reference 207/2s. Then I reset the crossover for a pair of Velodyne HGS-15s from 40 Hz to 80 Hz, and the sound stage size, sound stage depth, and sound stage detail improved so strikingly thoughts of changing anything vanished. I did redo the speaker setup extensively, including redoing all the SMS-1 bass manager connections, so I suspect the vast improvement was due to more than just adding 40 Hz to the range covered by the the subs — I must have fixed some previously unknown problem. Anyway, a setup that I thought was best for jazz and baroque now does large orchestrations convincingly with a sense of spaciousness I had previously imagined only floor standers could deliver. One detail I’ve noticed is that the power-on LEDs of the subs that were previously rarely activated are now usually lighted, suggesting the subs are playing a much more active role.
Well about not changing anything: I have a third HGS-15 I might install on the wall opposite the setup for a three sub distribution.

You have just discovered what many of us have been saying for some time now, that more subs is better, and not only for bass but for imaging, and making the whole system disappear. This happens because bass is so much different than midrange and treble. With bass the waves are all much longer than the room. So they cancel and reinforce creating peaks and nulls. You try and smooth it out with EQ, all you do is make them worse. Better at one point but worse everywhere else. More subs in more different locations means more peaks and nulls. But more subs also means each one can be run at a lower volume so the peaks and nulls are smaller and the overall result is much, much smoother. The next improvement will be to move those subs so they are not symmetrical. Symmetry is the enemy of bass, as it aggravates the reinforcement/cancellation effect. When adding the third put it likewise on a different wall and a different distance from the corner than the others. My system is like this only with 5 subs and the subs and the system entirely disappears, the room dissolves, you are immersed in the sound field, and the bass is freaking to die for. https://systems.audiogon.com/systems/8367 Search DBA, distributed bass array, Swarm subwoofer system, etc. |
Imo the best thing you can do for a system is use subs with a high pass crossover (like JL CR-1) to the mains. I wish more preamps had bass management in them. It could really cut down on the clutter. I have found most speakers cross over best at 60hz give or take. Not low passed but crossed over. If you are going to just low pass the subs they need to come in under the speakers. I like to be 1/2 octave above the minimum motion of the mains bass driver if using a 24 dB slope. 60z is good because a lot of bass drivers start to roll off around 60hz. |
