My studio speaker is

which frequency range is 40hz-40000hz


Now I need a subwoofer that can make a sound of 20hz. Which subwoofer do you recommend?

thank you

I'll save you some time and say what everyone else is gonna say.

You don't need a sub.

40hz from your monitors is already quite low. You probably don't need to go much lower than that. I'd say get a sub if the frequency response of your monitors was 60hz +

which sub you need is really depending on your main speakers, nearly
every setup benefits from a good sub
- 40hz on monitors is not linear but shelve off quite rapidly, not providing 40Hz @ 0db
- most 5 or 6" monitors are ported, sub bass response is much more tight on a subwoofer.
- Having the low frequencies being taken care of by the sub enables you to use low cut on your monitor which makes all of your amps power available for midrange / high freq duties, resulting in more controlled detailed sound
- also using low cut, enables a 6" speaker to work within it's optimum response range

So yes, in most cases it DOES make sense to use a sub in your setup, especially in EDM where the low/sub end is the most important and driving part.
so which sub to buy? one with high level stereo in and outputs and i would go for a sealed 10" of 12", not a ported version

MOST IMPORTANT: DON'T forget your room treatment

Is your room treated? If not I would spend the money on treating your room instead, Focal monitors are really good, ive got the Twins and my room has a good few bass traps - no sub required but i check my mixes on a system that has a sub

If you do get a sub i would just use it for checking - not for mixing but be aware that adding a sub can further excite room modes making things worse

Most guys seam to suggest keeping the full range and using the sub as a slight boost. Thomas jouanjean has an article floating about as to why. This was in reference to small to medium studios so I think it would apply in this case.

True, That can be a strategy as well, at the end it's all about extending your frequency response and the quality of your low end in order to make informed decisions rather than guess around.

so amending on the roll of of the monitor or replacing some low end and relief the monitor can both be strategies that work imho.

Just echoing what the best acousticians suggest. And using low grade crossovers isn't one of them.

true, I guess driver roll-off is more purist than shelving passive filters found in monitors. but then again, saving power for mid and high freq duty might just be the upside for just doing that.
