forget it... I'm out

A better question may be - I can get an MS909 FOR £X, is there anything else I should consider for the same price. FWIW I think the MJ would be better than the MS in most respects.4Real said:I like the MJ but the MS909 look and sounds solid. So which is better?
1. Which has a deeper bass
2. Which can go to a lower frequency.
3. Which has a better overall sound and performance
4. Which sub can deliver the goods for both music and home cinema impressively
The nice folks at this store Alf Electronics gave me a demo of the MS909. Speaking to the guys in there, they also rate the MS909 over the MJ Reference I MkIII. I was told that too deep a bass/frequency will only end up blowing air.
4Real said:From my understanding they were saying that if any subwoofer produce too deep a base or frequency i.e. really low frequencies then it will end just blow out air rather than blowing out heavy bass lines. Maybe you could clarify this for us since you are an AV consultant and would deal with subs of various range, quality and price. Your input is valid
4Real said:Aaaigh.. Nice info Hayes... So when they say it will end up blowing air he was "technically" correct. As the human ear won't pick up the "sound waves" but will still feel the vibrations.
Actually he also mentioned that downfiring subs which are "too close" to the ground is not "efficient". If I understand the guys at Alf Electronics correctly, a sub with higher stands/pins that create more distance between the floor and the speaker and/or sub unit will result in better/efficient sound performance. He reckon some downfiring subs though great in spec defeat the obejective with too low "a legs" to stand on...
4Real said:So the MJ down firing is a better performer than the MS909 forward firing?
welshy said:Does the MS909W only come with spikes? I have laminate wood flooring and even purchasing round feet for the spikes to stand on would still leave the sub to move around won't it? What would be the best way to keep this sub firm on my floor?

4Real said:LINK Scroll down untill you see the TS8 and the TD Sub. I thought maybe the leg design was to do with stopping vibration etc going into the ground like on traditional speakers and some speaker stands.
If you placed a forward firing sub in the middle of a room (with no help from the boundary), it would sound different facing you compared to facing away from you. And a downward firer in the same position will sound different again. Why would a manufacturer produce forward AND downward firing versions of the same sub?!! Pointless!!Nimby said:A downfiring subwoofer should offer no more or less than a forward firing subwoofer ->except splendid protection for the driver. (as mentioned by Hayes)
Raising a subwoofer off the floor might well alter it's frequency response. This has the same effect as moving a subwoofer away from a corner or wall. Both of which will reduce the output at certain (but not all) frequencies by reducing boundary reinforcement.
Sorry, but firstly, because sub A goes down to 10Hz and sub B goes down to 20Hz has no bearing whatsoever on which ones better. A sub can be 'tuned' with ports to reproduce frequencies it wouldn't normally be able to, which is not a good way of doing things, which is why the best sounding subs in the world are infinite baffle. Secondly, most subs that can reproduce frequencies below 20Hz, are doing so at up to -6db (even stupidly expensive subs can only reproduce this region at -3db, so something less than £1k has no chance), which while under the stress of reproducing many other frequencies at a much higher level, and hearing a lot of mid and treble from the rest of the speakers in the room, is going to be lost. If it's too quiet, you won't feel it. It'll just compromise the drivers ability to produce the frquencies you can hear. So at the volume that 15Hz would be playing at in the average AV system, the sub would probably more than likely be 'blowing air'.A decent output very low down (under 20Hz) is usually a good indicator of excellent overall subwoofer performance. The quality of the driver necessary to achieve very low frequencies at high SPLs helps it to achieve a dynamic and powerful performance at all frequencies within its useful bandwidth.
