My sub will be in the living room where there is activity. I want grills that will actually protect the woofer.
Reliable H/W has got grills for the right price but my SDX10 and APRs are surface mounted with that big gasket.

These don't look like they will fit over the gasket. I could cut the gasket down i guess or make a new gasket altogether but they look like they are meant to cover flush mounted drivers.

Basicly i want heavy duty grills, function over form to some degree

Down-fire the sub, no grilles required, and as down-firing adds a level of acoustical filtering of harmonic distortion it will sound better too.

Hey Bill, I'm curious to learn about the distortion lowering properties of a down firing design? I dont recall seeing this referenced before.

The output in the passband is omni-directional, so it's not affected by down firing. The above bandwidth harmonics, both those sourced in the signal and those created by the speaker, don't go around corners as well, so they're attenuated. And if the distance between the cone and floor is just right that space acts as a resonant chamber, enhancing the bass while acting as a low-pass filter to attenuate harmonics, just as a bandpass box does. Having the sub facing the wall does the same thing, though if the floor is carpeted that adds another dimension of harmonic damping.

what distance would it be?

I use these, but they don't protect against prying fingers.

Down firing? my box is already built with my amp opposite my driver and the room is carpeted.
that's not great for down firing i hear. Or is it?

i like those Z! why did'nt i see them? hmm
I'm gonna order one and try it out
thx!

update... shipping is more than the part!!! arg haha
i'll look around locally and see what i find but i think this is what i'll end up getting

Carpeting is not an issue if you use sufficient clearance - won't affect the response otherwise.
Here is Collo's rules regarding this - click on FAQ.

You can use a box program like WinISD to calculate it. Or simply experiment.

According to whom? Carpeted is preferred for down-firing, as the carpet damps reflection of harmonics while having no effect on the low frequency output.

i misunderstood.
i did the CSS Quartet10 build basicly just how CSS suggested, 18" cube, sealed box, its a 10" driver and 2 10" APR's. these guys are talking about ported sonotubes. does that matter?
i'll do a comparison of side and down when i get her finished this weekend.

NO. It was referenced just for the distance between down firing driver and surface to give you a working rule of thumb guide. The enclosure type is not relevant.

cool, cuz i have an extra 18" x 18" piece of mdf that i'm going to cut a 11 or 12" hole in and install my extra spikes so i can downfire it if i want.
like an adaptor plate if you will
ill do an a/b test

I should have taken a picture of the base itself but the sub is on that base with the feet upside down. i'll flip that over and i can put the sub on it so it will be downfiring.
You think that will work? i dont want to try it till the paint has dried for at least few days
it'll probably vibrate too much since it's not actually fixed to the sub huh?
i had the extra materials so i thought id give it a shot

If you mean it's going to be installe much like it is there with the lady painting it, but rotated so the driver is on the bottom, it should be fine.
I like the colour.

i've already got it set up to be side firing but i'll have that board with the large hole and feet as an option to point the woofer down but i'm not going to install it rather just set the sub on top of it with the driver facing down.

thanks! it should look cool with the black woofer and apr's.
