sub questions


Standard Member
i have a yamaha sw-305 sub that at present is inside a cupboard with double doors to the left of the tv facing the same way as the tv.

lying on its side the back of the sub is touching the back wall and the front is touching the 2 front doors of the cupboard. the sub has 2 8" drivers facing forward with the port in between also facing forwards. this means that there is only about an inch gap to the doors. do you think this will effect the performance of the sub much. i've tried listening with doors open and closed but cant tell much of a difference but im not sure.??:lease: :lease:

The sound of a subwoofer is a combination of the subwoofer itself and it's interaction with the room and if you are laying a downward firing subwoofer on it's side then enclosing it in a cupboard I would guess that it won't sound too good.

As a comparison, try putting it right way up in your room and putting it through it's paces so that you can hear what it ought to sound like.

Try putting blue tac underneath each corner of the Subwoofer.


Get a quilt and wrap it around the sub leaving the front and rear untouched - wouldnt want to encourage a possible fire hazzard.

If that doesnt work :rtfm: if you have one......

Have you calibrated your sub with your main speakers? It may be that your sub is set so low that it isn't competing with your front speaker's own bass output. So your speakers are masking (drowning out) the sub. Particularly if your front mains are bassy floorstanders.

It may be that you are listening at low levels? The sub would not contribute much to the mix then unless you turn it up to compensate for your ear's lack of sensitivity to low frequncies.

200Watts and 2 x 8" drivers should be making the cupboard doors rattle like hell on most material! It should sound awful with the doors closed!

Get hold of an SPL meter (RadioShack) and use test tones to confirm your sub is balanced properly in your system.

If you haven't got an SPL meter then (temporarily) set the sub by ear on a range of pop or rock music. The sub shouldn't intrude but should be noticable when you turn the sub down or off. Find a nice balance that isn't booming or inaudible on most music. For films you can probably crank the sub's volume up by a couple of notches.

Then start looking for an SPL meter. (If you haven't got one already).
