Looking To DIY...Quite A Few Questions I Need Help With

post #1 of 6
Thread Starter 
So I've given some thought to DIY'ing a sub for my HT setup (below). I've built ported boxes, sealed box, IB baffle, my false floor, etc for my car so I've got a little experience when it comes to building enclosures and such. My only issue is the finishing stages. I'd like something that's a piano black OR if it was a black vinyl look..it'd have to be good looking and not cheap (edges not matching, cheap vinyl, etc). I don't know much....anything basically lol...about finishing as this will be going in my house and I want it to look very nice. Room setup is:

20x18x10 = 3600cuft AND it's a more or less "open concept". Not enclosed like a basement (I can get pictures if needed to clear up things)

Now, I don't need to shake the entire house. Before this I had a PA-120 and at it's peaky as hell 50hz tune it was "decent", but not anywhere near what I want. My car has spoiled me and that wouldn't cut it, but I picked it up for like $60 I believe lol. I'm looking for something that will have great sound quality, but still be able to handle HT with authority when needed. I don't need a 15-20hz monster, but I would like something that is respectable in the 20's

I'm not sure what kind of enclosure I'm looking at here, but I'd like something that might be a little taller than normal and not stick out from the wall so far. I'd like something that isn't too deep (maybe 22-24") and DEFINITELY front ported so I can have it close to the wall. So let me get into a few questions and hopefully you DIY sub guys (and speaker for that matter) can really help me take off with some ideas. Thanks in advance btw!! biggrin.gif:D


1. Is there anywhere that sells pre-made boxes with a nice finish already on them?

2. How hard is it to really put vinyl (or if there's some other common finish people use that looks nice) on a box??

3. I understand DIY can be for fun AND also as a money saver, but when going with something like a single 15" sealed (possibly ported unless it needs some crazy 6cuft or something)..would it just be better to pick up say..an Epik Empire for $700 or whatever they go for? Looking to stay closer to $500 or so if that's possible.

4. I've been looking at DIY's for a day or so, but seems like most are multiple sub setups OR HUGE lol. 4 18's, etc. I'm looking for something that will resemble stuff like the Outlaw LFM-1ex, Empire, pb-12/sb-12, etc

5. Are there any advantages of going with a separate amp like the Crown XLS stuff over a plate amp? Also, is the Crown XLS stuff good/common? Any recommendations would be great, but I understand it's kinda hard to say until we get some subs in the picture.

6. 15" sub idea's?? Again, would like to go sealed unless ported doesn't require a massive enclosure. Not looking for sheer output; something very musical, but that can still get down into 20's easily with authority

And...of course I'm still going and will continue to research. I just thought I'd get a "build thread" type of thing started if I go this route. All the help I can get is great!

Sure you can buy pre-made boxes:

But it will eat into your budget. You should be able to go to Home Depot, buy a sheet of 3/4" MDF and then have them cut it to your dimensions for you. After that, you buy some cheap clamps (I found mine for $6 apiece) and then glue the box together with PL Premium and add some bracing. Fill in any holes, and then sand the box and you are ready for primer and paint.

For the wood, clamps, paint, and primer + other materials you are probably looking at about $100-120.

Cutting the baffles is probably the trickiest part if you don't have a router. You will either need to borrow or buy one and then cut the baffles using a jig. It sounds harder than it is, but plan on spending $50 or so at least for a decent router if you don't have access to one. That said you should be able to find a tool rental store and it would take about an hour if you have never done it.

A 3.5 cu ft box models sealed with this driver very well:

$120 for the driver.

This leaves you about $250 for an amp. You could either do something like this:

Or buy something like this which would give you more flexibility if you wanted to add a second sub down the road:

With your size room, duals would be awesome smile.gif

I am building 4 similar subs using the driver below in 3.8 cu ft sealed boxes and they model very well using an iNuke3Kdsp amp.

You could easily build two of the above subs for $700. I am building four of them for around $1K.

Oh and another site to buy flat packs:

Erich is a great guy and this is probably the easiest solution if you are not scared of a little primer and paint smile.gif

Thanks for the help. Is his website just not updated that often or what because it says most of his "flat packs" are out of stock
