That’s not up to just the sub, ….only the kick drum fundamental will be in the 50-100hz range along with the bass guitar…….everything else is up to your mains or washing through the mains to sub crossover region.
Room treatment is very important if you want that kind of bass, as others have said. Room modes will be difficult to get rid of. Bass traps help, but may not get rid of them completely.
Also, it depends on your mains. If you have a 5" trying to play loud down to 150 hz or lower, that will cause huge excursion and will muddy and blur the sound. Even some 6.5" drivers will do that.

Is it necessary to filter 150hz or lower? Sort of defeats the purpose. For the ‘ask’ here, my 7” Wavecor driver does best as the lower frequency driver in a two way with a powerful 3” full range crossed at 300hz. Completely articulate drums and bass with a very coherent overall mix
It is not necessary, I was just mentioning some drivers can't handle the lower frequencies and do midrange at the same time, especially at high volume. The 7" Wavcor should be fine.
How loud are you listening, in SPL? What distance are you from the speakers?
Also, which Wavcor 7"?

It's the alloy cone, don't know the model number. I have them in a THX setup as two-ways with the FRs. Covers a 3m x 3m listening area. Bi-amped and no DSP or boost. At the moment it's in separate cabs with the FR on a shelf and the bass cabs on the floor underneath. At some point, I will make a common box per side. Such a setup is very responsive to music and very coherent output. Makes a very good monitor for mixing a bass guitar with FL Studio drums or a Roland TR drum machine system, as on my JDXI and DJ-202......highly recommend these drivers as woofers in 15L-18L volumes ported at 35hz-40hz
My practical experience disagrees. It may not be the best driver for a dedicated sub, but its very musical and overall a good sounding driver.
Hi,
It's impossible to disagree, if you like it then you choose : ). However there is another way of looking at it, and this is trying to achieve sound accuracy as best as possible for given budget and/or time constrains. So for me, it should both sound pleasant and measure good. I always found these factors to be highly correlated, sometimes to a high degree of suprise. Also there is huge variation in programme material. Some types of music are not rich in content and forgiving to various distortions, others not at all, and this can be one of reasons why people tolerate different sound quality in their systems.

If we are talking about subwoofers, what matters most is how much air they are able to move, and the room response.
If you do not do anything special the room modes will fully determine the bass sound you get. THD will not matter at all.
More subwoofers in the room will help even out the room modes and will improve the sound, especially if you are able to control each differently with a bit of DSP, either build in the sub or as part of e.g. one of the newer surround receivers e.g. from Denon with multiple sub outputs and Audyssey to do the DSP.
One difficulty with a pure sub satellite setup in my opinion if used for both music and movies is that I want much more sub volume with movies than with music .... so need some way to switch. Therefore I also have normal 3 way main speakers .... with all the problems stated above

Hi,
I agree that the effect of room modes is huge. However having tested different woofers in the same room, with the same area/Xmax, I can not agree that drivers do not matter. To me, it is perhaps the largest factor in sound quality that can be changed and there is a big difference in the way it sounds. Units with high HD% can often sound rough or not clean at all, especially when working hard, muddying all sounds together. Nothing can be done about this with DSP or whatever, unlike frequency response which depends on woofer placement, number of drivers(as you mentioned) and so on.
