SUBWOOFER FOR MUSIC

Yes I know the cutoff points and I wonder why they don't keep that point as low as possible..I just don't understand..If I use a subwoofer I intend to cut it off at 35 hz..that ios also a bit confusing..my Paradigms have the 39 hz frequency range and then it says that low frequency extension is 25 hz..so I think it can go as low as 25hz but I am not sure how low it goes in my room..so if I have a subwoofer I will have to experiment with it..I wish the Pro 50 had a lower cutoff point.why don't they have the point as low as possible??
REL is also too expensive for me..

I would think that the setting of the cutoff will also depend on other things like room acoustics, amp, etc.

I'm also not sure how they specify that cutoff, but I imagine it is a -3dB point.

Generally speaking, I would estimate that you would want the cutoff on the sub set somewhere near where your speakers roll off to about -6 dB or so. Any higher and I would imagine you are likely to get too much energy in the room at that frequency.

I would imagine your speakers are -3dB at 39 Hz and -6dB somewhere below that (perhaps 35 Hz). The MJ cutoff at 40Hz is probably borderline for you. However, the other factors involved may or may not make it acceptably 'disappear' in your system.

For the pricepoint, I think the MJ is most likely a steal and would be worth a shot for you to try, especially since it's about half the cost of the REL. I would suggest you find a shop that might let you demo the MJ.

I'm not sure about other subs, but at this price point, I doubt there are others that have the same musical performance as the MJ and REL. The only other that comes to mind is the Monitor Audio ASW100? Also with a cutoff at 40Hz and also cheaper than the REL. Or perhaps you can find a used Q150E or an older model like the Q100? Check the cutoff specs first though.

what are your main speakers Chris??
I went to a hi-fi shop today..they sell MJ..I told him that I have Paradigm 100 and he said for Paradigm the mj50 would not be enough..he told me that the MJ Pro 50 would not keep up the pace with Paradigm..he suggested something bigger..so I think I would go for Servo-15 at the end but I am still not sure..by the way in UK the Servo-15 is just for 750 $ ..so it is cheap...

My mains are Snell E.5s.

If the dealer will let you home demo the MJ, I would try it. All the reviews I read said the unit has very impressive output for its size/amp rating.

Hey Aram,
using a subwoofer is okay, but there are great differences between them. The most subwoofers are for home-cinema or for deep bass. High-end subwoofer are making not so deep frequences, they are constructed for subsonic bass. That's a sort of bass you cannot hear, but the space and the contour of the instruments and voices is much better then before. There's a link for you: www.audiophysic.de
Their you can see a high-end subwoofer, it cost about 2000 Euro, but it's the best of the best (i read it in high-end magazine).
