PA Knock-Down Trapezoid Plywood Speaker Cabinet for 15" Driver
PA Knock-Down Trapezoid Plywood Speaker Cabinet for 15" Driver is rated 4.1111 out of 5 by 9.
Rated 4 out of 5 by from Great for the PriceI found the 11 ply birch decent quality. I have used better but at a price.I built mine as a coaxial Mid Hi pak, 15" and a 1.4 exit horn, so I cut the over all height by 8 inches. Use a lot of wood glue, and definitely seal the inside with RTV, about 1 tube per cabinet. Also I used the pieces provided for mounting a grill to brace the baffle on the inside. Very solid. Use a lot of putty, sand well, and you end up with a nice box. Take your time, do things in stages. Let glue and RTV cure. I also used a router on the corners. When you drill holes, go slowly. If you push too hard using a hole saw, you could remove some of the ply. Go Slow. I will try and add some photos later. The one thing I really didn't care for was the gaps left between the baffle and sides top/bottom. Had to use a fair amount of putty to seal those up.

Rated 5 out of 5 by from Very simple assemblyI needed some quick and sturdy boxes for some JBL D-130 woofers and these did the trick quite nicely. I finished them with black "Restore" deck paint after rounding off all the edges with a router and 80 grit sand paper. My main advise is to cut your holes for your horn and ports on the baffle before assembly. I only wish that Parts Express offered a pre-formed grill that fit these cabinets with no modifications required.

Rated 5 out of 5 by from Not a bad set of boxes.Been doing sound for a long time and if you load these with the right components these boxes rock. Just recently took out a couple of 22xt peavey drivers and newer black widow 15's out of an old sp3 cabinet that was finally falling apart and recycled everything into these newer and much lighter boxes. Ended up having a nice pair of pretty much brand new speakers. Using peavey sp2g crossovers which work fairly well with these boxes. Instead of using port tubes I cut slots for handles that act as porting. Overall was a quick and easy project to complete. Also, if you are using heavy duty speakers that move a lot of air you MUST seal every joint in these boxes with silicon and use a generous amount of glue on all cuts and tabs. The only suggestion I would make is a better system for grill covers to be mounted. These boxes are made for a P.A. not home stereo so a steel mesh or expanded metal front should be used not grill cloth.

Rated 4 out of 5 by from Rumble FilldirtA great choice for me.Pretty good Birch with very few voids visible on the edges.Cut edges require a little sanding but fit together well after some TLC.Each box eats up a whole pint of wood glue and a whole tube of caulk, but is very leak free and strong in the end.I added some 1" oak dowel rods in 2 places as bracing and after that the cabs were rock solid.They ring like a bell when I rap on them.I also doubled up the baffle as I used these for 12" woofers and had to make a smaller speaker hole.Adding a layer of 3/4 Baltic Birch to the baffle made the boxes very stiff.They ate up a gallon of texture paint and a quart of oil based primer, but now they look awesome.I recommend these to anyone who doesn't have access to a complete wood shop, or as anyone's first DIY project.These boxes rock with 12's, I can't imagine them with 15's installed.Just for the cost of wood, these are a good deal.Very satisfied,Rumble

Rated 2 out of 5 by from Needs better plywoodThe cabinet enclosure volume is too little for most 15" drivers, if you correctly subtract the amount of space the driver itself occupies inside. So I put in 4 12" as two pairs of clamshelled isobaric pairs. And I added a thick fromt removable baffle board. You can get decent plastic or metal cabinet corners for 15 degreee trapezoids, and they make it look a lot more finished. But in the end, this kit is screaming desperately to be made of better plywood. I had no idea they made plywood this cheap.

Rated 4 out of 5 by from Good concept that needs more thought in it's executionThis is not just some kit that you can slap together and expect good results. First, you need the right tools. You're going to need to take your time with it. After getting your holes cut for ports, mid, tweeter, pocket handles and terminal cup, which could take anywhere from 1-3 hours, it will take about an hour to assemble. My advice from actual experience with this product is to assemble the cabinet as directed, with one exception. Don't glue the top of the cabinet on until you are finished loading your drivers, crossover network and have given it a good test run. This made my job so much easier because I had free access to the inside walls of the enclosure.After I was all set up and ready to go I cued up some music and set the mixer gain at a moderate level and punched up the bass. Vibration. I heard an obnoxious rattling that just kind of droned. I lowered the volume. Even at low volume there was undesirable noise emminating from the cabinet. After some investigation I discovered that the front baffle was flexing between the woofer and midrange. This is my main reason for advising to not glue on the top panel. After my little test run I simply removed the top and installed a T-brace with the top of the T pushing against the spot that was rattling. It took all of 5 minutes to solve the problem. I think including a brace in the kit would improve customer satisfation since some people might think it's not so great a product because they don't have the experience to deal with a problem like this.It is a strong, lightweight box when finished and I am very please with it's performance now that the bugs are worked out.

Is it possible to order these cabinets with a blank baffle so i can use with 2 twelves instead of a single 15?

Asked by: Kc1200
These cabinets are shipped to us this way and pre-packaged, so there is no way to substitute the baffles.
