Infinity 1260W Vented Coffee Table Subwoofer

[Chris Roemer]

FYI, that's about 1.8cf for Vas.
Factory specs: Fs 24 (not 32 - but that's not THAT bad), Qts 0.39 (not 0.62 - this is W-A-A-Y off and throws off BOTH F3 AND Vb/Cb), and Vas 2.9cf (not 1.8 - but that's not off a LOT either).
As Qts rises, the box model might not change all that much IF Fs also rises (which it does, here) and Vas drops (which is also the case here). A Qts around 0.48 would be "reasonable" (but not really 0.62).

I'm not sure how heavy that your table is but adding more wood might make is super heavy. There is always the fabric idea or I used a veneer on mine. Though the damn thing still weighted 150+ lbs when I was finished.

You might consider hardwood flooring.

Get a yard or two of "vinyl" leather from a fabric store, and a can of 3M spray adhesive and wrap it. You should be done in 15 minutes . Here's a before / after of a compact guitar cab I wrapped a few months ago, trimmed with poplar.

I am still debating that, something dark and easy to ignore visually would be nice, but I am also contemplating paneling.

How are you planning to finish the sides?
I built a coffee table sub a few years ago and love it.

This is a great idea for a home theater. Good job!

Does the coffee and other drinks rumble on the table when is at high volume?? :D

Literally when the Deathstar exploded in Star Wars, everything on the tabletop 'jumped'. lol.

Awesome! I love the top. I just started my build today for the 1262, and now you have me reconsidering the top. The finish on mine will be distressed as well.

Re: Infinity 1260W Vented Coffee Table Subwoofer

Hmmm, I actually never have. I measured the impedance in the box (which asserted the tuning) but I never did check the driver. This maybe have been in my period between DATS and LIMP, and I just didn't have the setup to do so. I have no problem measuring the driver if you want though (and it is well broken in!).

That would be interesting, I measured 1 of the 2 1262w I have and does not measure as advertised:


I'll try the other next week.

Re: Infinity 1260W Vented Coffee Table Subwoofer

You got me, I was taking some liberties there, its likely more like 275 watts power handling. I doubt I've ever hit that in my apartment though.

Fair enough, I can't see that I'll ever be able to shake the walls (much):D

Re: Infinity 1260W Vented Coffee Table Subwoofer

Beautiful build, dude!
Um, gotta question the excursion though - the first Unibox shot shows you are exceeding xmax at about 35 Hz.
Do you figure that boundary reinforcement will give you extra headroom?

(Not questioning your competence, I'm just trying to understand sub engineering)

Jason, I guess you measured the T/S, would you mind sharing them?

Re: Infinity 1260W Vented Coffee Table Subwoofer

Correct, here is the box model at 300 watts. It is serious business
