I'm looking for a small rectangular sub for my bedroom. The sub would be in a stand under the TV so it must not exceed 27" large and 8" high

budget would be around $300 maximum

it's for watching movies only

Any suggestions?

thanks

RULE #1 OF SUBWOOFER PLACEMENT:
The most aesthetically pleasing location will always result in a null at the listening position.


This, of course, is not always true - but, basing your subs final placement on aesthetics is a bad idea. It will almost always sound better somewhere else. wink.gif

Thank you ! Looks interessing and matching my size requirements even if it's a bit small (would still have room for one that is a little bit bigger)

What is the difference between a "down firing" sub and a standard sub ? does that means the bass sound will be sent to the ground ? If so it would be a problem if i put it in a stand under my TV since it would make everything shakes...

I dont think people here are interested in making recommendations for *small* subs... and 8" height leaves no room for even a 8" woofer unless it points down, so yeah.

How about making some rearrangements--maybe find a sub that will be big enough to BE the stand for the TV, instead of being IN a stand... biggrin.gifbiggrin.gifbiggrin.gif

The problem I see with recommendations of this type, if you can call them subwoofers, the recommendations are more like full range speakers which enhance one's main speaker output as opposed to being a "subwoofer."

The point, if someone wants a subwoofer recommendation, they need to include size restrictions that will allow people to recommend "SUBWOOFERS."

The point, when size restrictions become so severe, one is no longer recommending a subwoofer.

Just saying.

My recommendation, lose the ideal of fitting a subwoofer into this "SLOT," accept you're going have a big old ugly box, out in the open, that doesn't bled perfectly with the decor, and enjoy.

My question was about downfiring sub, i asked what is the difference between a downfiring and a normal subwoofer. Does it means that the downfiring sub will send sound to the ground ?

Down-firing means the driver is aimed at the ground rather than toward the listening position. Since low frequencies are omni-directional, you will hear/feel bass regardless of which way the driver is facing.

Ok but if i put the subwoofer over a glass cabinet does that means the glass cabinet will shake because the downfiring sub will send vibrations toward the ground ?

If the motion of the driver causes the subwoofer cabinet to vibrate - regardless of which direction the driver faces - that vibration will be transmitted to the glass shelf.

Placing some isolation material (rubber pads, a square of puzzle mat, etc.) between the subwoofer and the glass cabinet should solve the problem.

But is there more vibrations sent toward the ground with a down firing sub ? I don't understand what you mean about the driver, does that means that all sound that comes out of the subwoofer will come from UNDER the subwoofer (so the bass is send in direction of the ground) ?

No. Low frequencies are omni-directional, so regardless of which way the driver faces, the bass will radiate outward in all directions equally.

No. Imagine a puddle of water. Drop a pebble in it and watch the ripples radiate outward in all directions equally. The driver in the sub is the pebble. It doesn't matter which way the driver points, the low frequencies will radiate outward from it in all directions equally. The driver doesn't "fire more bass in the direction it's pointing".

That's not to say buying a tiny "subwoofer" to put in a GLASS CABINET is a good idea... smile.gif
