PA Knock-Down Trapezoid Plywood Speaker Cabinet for 12" Driver

This American-cut knock-down trapezoid cabinet is perfect for your next PA speaker system project. Pre-cut hole accommodates most 12" drivers. Includes CNC-cut plywood knock-down panels, optional front protection grill supports, wood screws, and assembly instructions. Popular trapezoid shape can be used horizontally as a floor/stage monitor, or stood upright for traditional vertical applications. The 3/4" plywood used in this cabinet is exceptionally smooth, dense, strong, and virtually non-resonant. The high quality low-loss wood means more of the power that drives the speaker will turn into sound and less will be used to shake, rattle, or resonate the cabinet.

Specifications: • Internal volume: 1.6 cu. ft. • Dimensions: 24-1/2" H x 17" W (front), 10-1/4" (rear) x 13-1/8" D.

Rated 4 out of 5 by from 12" Knock Down BoxThis is an affoardable way to put together a near quality cabinet. The finish & fit is typically good and assybely is easy enough. You can increas the net voulume by front mounting your own baffle, this will get you slightly more than 2 cu ft!On the negative side you will need to pre drill ALL your holes or stripping screw heads will results- be sure to get the proper tip to fit the screws provided. You also shoul use some carpenter glue to secure leak free joints when putting together. This is not provided. I also incorperated some internal bracing as the wood is not a full 3/4" thick.These are good cabinets and with some extra knowledge you can put them together very well and end up with a good looking & sounding cabinet!

Rated 4 out of 5 by from A Nice Winter Project!I purchased two of these speaker cabinets for a winter project. I chose these particular cabinets because I wanted the 3/4 " thickness for extra strength. They went together well with no problems and with some sanding, staining, and polyurethaning turned out respectable. The dado joints and pre-drilled holes really helped. Fine furniture they are not, but for the price a good deal, especially with free shipping. GREAT SERVICE FROM PARTS EXPRESS!!

Rated 3 out of 5 by from Decent for the priceI bought 6 of these for a friend's school. PE only had 4 in stock, so they shipped them, and I got them very quickly. Fit and finish are not great. There were some gaps in the plywood, and corners and edges did not go together flush. Also, the woofer cutout is 11 inches. I used Goldwood GW-12PC-4 woofers, which require 11 1/8 inch cutouts. Overall, for the money, they were easy to work with, went together well, and , with a little extra finish work, turned out to be pretty good sounding cabinets.

Rated 4 out of 5 by from made in china not usa!!at 1.55 cu ft, it is to small for a 12" speaker.cutout should be for an 8", some 10" could work in this.as a monitor, the sides are angled to shallow.aim's the baffle at your knees.wood is decent. prefit adequate. screw heads don't sit flush with sides. bear down and the heads strip.grinding a must. sanding, too.solid after plenty of wood glue.would recommend, probably.

PA Knock-Down Trapezoid Plywood Speaker Cabinet for 12" Driver

What is the true weight of this cabinet?

Asked by: nola50

Would this cabinet be an appropriate volume for a 12-inch coaxial floor monitor? I was thinking of installing the Eminence Beta-12CX and PSD:2002S-8 with the PXB2:2K5CX 2.5 KHz x-over in this box.

Asked by: Deff
Yes this will work well with that driver. I would recommend a 4" diameter, 2" long port for a tuning frequency of 45 Hz.

Are the screws for fastening the speaker to the baffle included?

Asked by: Zippy
No, it only comes with the wood screws for assembling the enclosure.

I like the 12" trapezoid 1- Do you make one that would used my 8 inch peerless woofers HDS seriessame 1.6 cft I purchased from you quite a while ago. 2- on the 12 inch does it have any braces internally. thx fredc

Asked by: salsaf
We do not have any trap cabs for 8" speakers. This 12" model doesn't have any internal bracing, but adding this with dowel rods would be quite easy.
