glass in front of driver?

[davepenney]

I am thinking of building a sub that doubles as a coffe table for my a-level project.

My plan is to build a very attractive table with the sub mounted on the top surface. Above this(around 25mm) there will a thick glass top.

Does this pose any problems, other than not being able to stand your coffee on it.


thanks.

You would want to make sure there is enough airspace around the cover, 25mm is not very much (rule of thumb is 3 to 4 inches, which would be over 100mm). Could you just fire the woofer downward??

Firing downward has a lot of advantages (protection of the driver, more efficient coupling to the room), unless your goal here is to show off the driver. If you leave a 25mm gap on top, the question of probing fingers will not be an "if," it will be "when" and "how bad."

[paulspencer]

upward firing is a problem, a pratical problem. If anything happens to get on top of it, it will rattle and get fired up in the air and the cone will hit it and you may cause cone damage - gravity doesn't help. Downward firing makes more sense, perhaps hide the fact that it is a sub, but make it very heavy!

Rear side of a driver looks way cooler anyway.

Fronts of drivers are boring
Once u have seen a couple, mag cone, paper cone, plastic cone, alu cone, phase plugged, none plugged, fiberglass cone, aerogel cone, kevlar cone, SS sliced p cone, carbon fibre cone, inverted dome, non inverted, dust cap as one cone, forward surround, bakwards- half way surroud. Really once you have seen one or two you've seen them all

The rear of a cone, yeah nice too, I take out the drivers in my speakers, or invent something to tweak no matter how dumb, just to see the rear of the cones once in a while. When you do this, you know you've lost it, utterly DIY audio obsessed.

Go into madisound storeroom for a few hours

If I won the lottery Id buy like 100 drivers pairs in a shopping spree just to see what they all looked like in the flesh, ofcourse I would use them too . Or place them round the room as ornaments.

Your xmas tree has a star or fairy on the top, mine has a w15cy001 speaker cone with a plasma tweeter on top of it lighting up the whole shebang. Chocolates for the kids on the branches?? Perfect lay silver inductors, babals? vifa xt25's oh and you think you have tinsel, well ive got Tinsel LEADS! HAHA.

OK thats bit much me thinks
Where did that number go for the therapist.

you might wanna look at some subs that e-design makes. http://www.edesignaudio.com

there speakers though used alot in cars would make a great home sub. They also would work up or down and you really wouldnt have to worry as much about fingers really hurting the cone because the cones are flat, and the material the cone is made with is pretty sturdy. These are great subs, and i have absolutely loved the sound and look of every one of these i have seen.

good luck

[davepenney]

To Fulfil the design brief I need something of the driver to be visible on top side under the glass, ideally. This is where Im a bit stuck...

any ideas?

another problem i have, is that I live in the UK and all the drivers I find on the net, the shipping is too much. I was originally thinking of using a shiva (top of my budget), but am not sure as I don't know where this project is going.
