Infinity 1260W Vented Coffee Table Subwoofer

[JasonP]

Silver1omo had asked a while back in Speakchat for a picture of my coffee table subwoofer. I figure I'll post it up here to motivate me to finish it (I lack an SO to convince me things need done!).

My point and shoot canon wants more light than I have access too in my living room, so pic. quality suffers, my apologies.

I'm really proud of the table top. My Dad and I collaborated on that. Its all 2x4 and 2x6s edge glued, stained with Minwax English Chestnut and a couple coats of Danish Tung Oil. Finally a sprayed on a couple coats of Deft gloss lacquer. I like the rustic look, and it does that in spades. Sound wise, its an impressive sub. I have it powered with an INUKE1000, which is more than enough for HT use in my smallish apartment.

Very cool. 150L? 17Hz?

Re: Infinity 1260W Vented Coffee Table Subwoofer

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

That is nice....! what are you planning for finishing the sides? A simple black duratexwould look really good with the metal driver and rustic top. Or you do you have something more elaborate in mind?

Does your coffee do the jurasic park tremors, when the TRex arrives?!?

Re: Infinity 1260W Vented Coffee Table Subwoofer

Man, now I want to re-pourpose my 2 sealed 1262ws to endtables...
Not sure if 150L or 120L
120L at ~20Hz seems to loose about 2-3Hz in extension and have a bit less excursion...

Great project!! That woofer is really nice. Forgot I had an extra one left over from 84" tall horn loaded sub. Really moves a lot of air. Nice woodwork!!

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

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)

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!).

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

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

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.

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

Re: Infinity 1260W Vented Coffee Table Subwoofer

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