Hey all,

First time poster here. I have to say that this is a great forum! Lots of GREAT advice and examples to get ideas from!

Here is my current project. Basically it is a 7 cu.ft. ported enclosure tuned to 20hz. The net volume is a tad over 6 cu ft. I am currently planning on powering it with the Dayton 1024 watt plate amp. I will have a hp filter set at 18hz. That setting seems to give me the best response curve. The enclosure will be constructed out of 1" MDF with the appropriate bracing. In the picture I haven't finalized the bracing design yet, so please disregard what you see there as far as the bracing goes. The enclosure will be covered in red oak veneer and stained to match my entertainment center. I will post pics once the construction begins.

One question though, what is the typical room gain for a sub? I have mine in the modeling program set to +3db at 60hz. I haven't messed with room gain before, so its new to me. Anyone have any advice on this?

Thanks in advance for your help, and thanks for looking!

Here is the rendering and the pdf of the bb6 design.

Re: Dual RE SE-12 End table sub build...

Hi Talunceford, welcome to the forums :wave:

I have to say I'm impressed with your image, top marks on that. This indeed looks an interesting project. Generally room gain will yield upto 6db of gain, but it different in different rooms. If you work to +3db as you are you wont be that far out, and may have a pleasant surprise from the final product if you get more :T

Your cabinet ideas all look good, 1" MDF is what I use and a properly constructed cabinet is very solid (and heavy). I look forward to keeping up with what you have planned!

Thanks moonfly for your comment. I am really excited to get this project under way. I will start cutting the pieces tomorrow. I have access to a panel saw and should have them cut in short order. The way I have it figured up, I think I will use approx 1 3/4 sheets of 1" MDF. Maybe a tad less than that. I will take pics once I get started.

Re: Dual RE SE-12 End table sub build...

Oh and the rendering... LOL, I was in the civil engineering field for over 15 years as a cad tech, I don't know how to do anything that doesn't look like that. I model things as accurately as I possibly can the first time around and make sure that they fit the first time without mistakes. I guess all of the engineers that I have been around drilled that into my head LOL!

Thanks again!

Re: Dual RE SE-12 End table sub build...

If your cutting your panels to specific sizes then thats great, but if you intend to cut panels for the braces, then cut the windowed parts out, you need to make sure the brace panels arent exact size. Make them a couple millimetres smaller than the computer says they should be. In the real world you can fit a brace with no gap at all between it and the outer panels of the box.

Another way around that is to use a router to put a small trench on the inside of the outer panels for you brace to sit into. There is a bit more work in that method though, although it's the better way to do it IMO.

Re: Dual RE SE-12 End table sub build...

Construction started today at lunch. I have nearly all the major cuts done. 1" MDF is some HEAVY stuff! Thanks to my buddy James for helping out! I also have a few updated renders of the enclosure with the new bracing design. Here they are.

Wow, excellent images. This sub is going to be a great addition to the room.

Could we have some lighting in the pictures though, I cant quite vision that :D, and perhaps some texture mapping :rofl:

Well, here are some pics of the port support. It took me a couple hours to complete the support, but I think it turned out great. Not a whole lot of time to work on it today, but I have Monday off, so I will make some serious progress then.

Liking the effort put into that brace, it'll certainly do its job? Looks like you have some structural engineering influence.

Thanks! I used to work for a structural engineer. I inspected quite a few different structures (bridges, box culverts, etc.). Based my design off of that type of stuff.

Re: Dual RE SE-12 End table sub build...

I wish I would have had a smaller jig saw blade, a blade made for scroll type cuts. The blade I used was not really appropriate for making the tight radius cuts that I made, but I had a trusty wood rasp to clean up the mess. I then went through all of the cuts with a RotoZip to help smooth out the cuts even more. Once that was done, I took it over to the router table and finished the cuts off with a 1/4" round bit. I still have to sand it, but other than that, it is finished.

****** UPDATED END TABLE BUILD STATUS (w/pics) ******

Well, I made some good progress on the enclosure today. I made some design changes (cosmetic) and I think that they were worth the extra effort. I have to still assemble the amp enclosure and cut out the back port holes and cut out the area where the amp will reside. The pics you see below are of the enclosure resting on its top. I also included a couple new renders that I made today before construction began.
