subs don't have to be 12" or even 10" they can be 8" or even 6". They don't have to be boxes either they can be tubes
Yes, indeed. The 3 subs I mentioned in my earlier post were discussed with my mate and his wife where I made suggestions about how they could be integrated into their room. The boxes had a small square footprint and were built to the height suited to their purpose. One was placed next to a bookcase and painted the exact same colour. The second served as a stand for a large pot plant and the third served as a side table replacing the table that had been there before. The whole installation was unobtrusive and took up very little extra space.
Where there is a will, there is a way.
The tube MC referred to allows more options. They can be used horizontally and vertically. As well as placing behind a sofa they can be used in the horizontal corners formed by the wall/ceiling junction.
6.5" drivers are common and they do not need to be specifically designed for 'subwoofer' use. If you regard them as 'acoustic equalisers' they will do something that is difficult to conceptualise if you have never heard a DBA. You get the music robbing nulls filled in and the shouty peaks tamed.
The above is suggested for owners of small rooms always complaining that they just don't have the space. If you do have the space then go to 10" or 12" drivers and enjoy the benefit of muti-subs down to a lower frequency.
The number of subs and their size depends on who wears the trousers in the house. In the above example my mate definitely wears the trousers, he just has to ask his wife which ones he can wear! 😉
Absorption, diffusion and bass trapping will take this to the next level. I have been playing with this for some time and I can tell you that some of my mates who were always introducing new and expensive components, endlessly chasing their tail, have mellowed out and are basking in their glorious sound, being more interested in the music now.
