Anyone need a Subwoofer?

[xtremerevolution]

I just discovered that they actually had quite a few T3 audio products available. A lower powered 400W version is for sale for $49 in both a single and dual 4 ohm configuration.

Seeing how fast the 600W version went, anyone who missed the last one might want to jump on this one. I can model a few boxes if anyone is interested in these as well.

For that 400W one, do you think the amplifier (Pioneer 5400T) would be able to power it? The amplifier puts out 380Wx1 at 4Ohms stable. I think a single 12" subwoofer would be sufficient for my needs, considering the 8" Bazooka was fine for me at the time this could only be a upgrade from that.

Yeah, that 4ohm 400W sub would be great with that amp.

Phenomenal, I saw another one on ebay for $50 w/ free-ship so I may just snag that. Do you think that a single 12" would hit loud enough? Im not going for ear painful deafening just need more bass than the 8" Bazooka put out. Could you also help me design the box for this woofer?

Thanks!

For you, I'm sure it will be loud enough. You're looking at 2.5x the cone area as an 8" bazooka sub, and more excursion to boot. I can design a box for sure. I'll try to get around to it tomorrow or the day after. Better jump on that sub before it sells out.

Plan on purchasing it tonight, and thank you for the help!

Hold off on it just a second. I'm working on a box and it looks like you'll need to go ported, so I'll have to tell you what round port to also order from partsexpress. Do you have access to fiberglass or mineral wool insulation or batting?

Alright, ill hold off until you give me a go. By access do you mean it being available to my house or by being able to purchase it locally? Stores near me include Lowes, Home Depot and Walmart. I think one of those would have it though.

Ok, got a box model ready for the T400 Single 4 Ohm VC.

You'll need 2 cubic feet gross internal volume using 3/4" MDF. I would recommend a double thick front baffle, but its not absolutely necessary. Use one 4" round port at 17" in length. This is the port you'll need:

One set of dimensions you can use for this size is 16" height x 20" width x 16" depth. This tunes the box to around 30-31hz.

I would very highly recommend that you line the walls with fiberglass or mineral wool material as described a few posts back. If you need box carpeting, order that at this time from partsexpress, as well as a terminal cup. Let me know if you need recommendations on exact parts.

By access I mean can you get it readily. Home depot and lowe's both have it but it may only be found in large packages of way more than you'll need. Some people have extra lying around from past jobs. You don't want the hard foam board material either, as a lot of that is closed cell foam that won't work.

For a good music variety in a more SQ based install, run this at 1.25 cubic feet gross volume, 3/4" MDF, double thick baffle with the second baffle acting as a recess and reinforcement.

Thoughts on this box? Btw, there's an autoplay youtube video about halfway down the page to the left http://www.ebay.com/itm/New-Black-Ca...-/330661072592

Seems fairly cheap so no telling how good it actually is, but seems to meet a couple of the specs you went over. $40 to my door sounds way better than trying to make my own though

[xtremerevolution]

Looks like it will fall apart in no time. Anyone who knows how to build a sub box knows to build it using wood glue. I'll bet that's screwed or nailed together and the caulk is used to attempt to seal it. You never need anything more than a generous bead of wood glue at the butt joints to seal a box that will last a lifetime. I guarantee a ton of leaks and it will probably fall apart after a while

You get what you pay for, and prefabbed boxes flat out suck. I have never seen a well built prefabbed box, at least not at that price point. Please build your own. I will even teach you how to do it.

Yeah, prefabbed boxes are not the way to go if you have ANY other option! And ya, PE seems to have bought out the last of T3's crap now that they are out of business/restructuring/redoing whatever lies they are telling now.. (I despise J.Demuth/Ed Lester with a passion) That said, these are GREAT prices on some decent woofers. So far Ive ordered 6 of the t600s and 6 of the t1000s (incase i get bored of the 600s) You would have a hard time finding a comparable woofer for the same price.

Cool, I had a feeling it was probably garbage. I guess I'll give making another box a go, should be way easier than that slotted rockford box my buddy and I built. Not to mention smaller, by a lot.

Yeah, they're easy to build. I can knock them out in a couple of hours now, start to finish if I already have the materials.

Use a bead of glue almost as thick as a pencil to cover the surface of the wood you're gluing together. Clamp it down with wood clamps, wipe off the excess that seeps out through the seams.

I can build boxes for people as I have all of the woodworking materials needed to make a perfect box, but chances are most people here won't want to pay what I'd charge to build a box and shipping.

I could possibly do a group buy if there were enough people interested and wouldn't have to make several trips for MDF or spend the time to setup each time.

I think im going to build my own, with your help that is whenever you're free. Its like the saying, "Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime." I would personally rather have the knowledge to construct my own box, and know its done with quality in mind and then be able to construct another down the line or help a friend construct one too.

I almost have the speakers in, running the wires through the door jambs turns out to be very tricky when its 39 degrees out and sun has already set where I am. I hope to have them in though by tonight, fuses for the distribution block should be here within a few days and then everything will be set to go for the sub!
