Use your judgement. Place bracing wherever you think the enclosure will flex. Some guys use wood dowels to do it, some guys use 1x4s, some use 2x4s.People use whatever will work. If you're really have trouble with simple things maybe it would be a better idea to have someone else build the box for you instead of attempting to do it yourself.
I wouldn't mind having someone build one for me, except I don't want to pay an arm and a leg. If someone is near me, I live in agawam, ma, such as connecticut, let me know so we could work something out.
yea to get an idea of what internal bracing is go take a look at the the (Dwight-Satisfied Customer) thread and look at the window pane style brace woodlawn uses tht is an example of internal brace.
IMO with subs 1000wrms or less u really dont need to double baffle ....still i good idea to brace internally where necessary depending on the shape of the box...
IMO, doubling up on a front baffle is waste if the enclosure is a daily "listener" box. Bracing can do the job just fine to minimize any " flex " issue without adding an azz load of weight to the enclosure.
However, doubling baffling is more a personal preference rather than a necessity.
alright thanks guys, i think im going to try and build my own, im gonna have some free time over the winter, so why not right. you guys have any pics of some good bracing i could use
I had a suspicion that was you that e-mail me for a quote and I replied back that for the dimensions stated there wasn't enough volume to RE's recommended spec's for the SX 12 ported.
I also said as well that you would have to increase the dimensions in order to achieve the required spec's.
Maximum Dimensions W x H x D - 18" x 14" x 16" just ain't going to cut it, not with the small amount of port area at 1000 watts.
Ya gotta come up with more room for the enclosure size, unless you say that all there is and I do the best I can with that as long as you understand there's going to be some port noise or the net volume drops to maintain port area at a reasonable size.
Or
Bag the SX 12 and go with something that going to work with what ya got because I'm not going to build an enclosure and get my azz ripped after the fact.
Yea i understand, the largest I would really wanna go would be w x h x d - 21" x 14-15" x 17" somethin like that. would that be sufficient? Im trying to keep the box short enough so that the hatch cover can lower properly without laying on the box, had that problem with my old 15".
Well actually could you give me some minimum requirements, like different measurements that would work without being too tall, nothing higher than 15", that would meet re's specs
Well, what could always be done is at the point where the top of the box would hit the underside of the hatch is angle the top of the box down so the hatch won't hit it.
That's a easiest simple solution to that problem, all i would need to know is what the angle is or what I could do is angle the front baffle as the shortest top depth of 16-17 inches and the bottom depth is whatever to make up for the volume requirements.
Here's what I'm going to do:
Use the max dims ( 21" w x 14.5" h x 16.5" d )
The 16.5" is will be the top dimension.
The bottom dimensions will be whatever it has to be to meet the requirements.
