    Well, I finally made a decision on my sub design. I figured for my needs a 75l DPL12 should fit the bill, at least for now. I am a virgin when it comes to subwoofers, or DIY projects as far as that goes. I figured that I could take the money for a plate amp and put it towards a new Denon 1603 receiver (last years model i.e. on sale) and use my NAD3150 to drive the sub. I was a little concerned about the power, ~60 watts/channel @ 6ohms or bridged for ~150 @ 4 ohms. Because I wanted to use the NAD and wasn’t sure that I wanted to commit to a 3.4 ohm draw, so I installed a dual binding post cup so I could the voice coils separately or in parallel. So far I find that I have more than enough power running the VC separately (left – Right).

    I have to say that I am thoroughly impressed with this little sub. Although, after I finish building a pair of surrounds and center channel, I think that I will have to try Chris Brady’s push-pull TL sub but first things first.

    good looking sub, I like the seperate base design. I wish you would have veneered the back, but I guess whatever suits your needs if it will never leave the back wall.

    I wish there would have been a picture of the driver.

    I would have done the back, but the veneer that I bought came in a rolled 24"x96". This didn't leave me enough material to cover the back, another $50 + tax for another strip of veneer. I don't think that it will be out from the wall in normal use, besides I am already thinking of another sub design. Not that I am dissatisfied with this one, I’m hooked on DIY now and would like to experiment with other designs. As for this one, I wish that I had built this sooner.

    As for photos, I have a few more during construction and I’ll probably take a few new one’s. like the driver photo.

    Is there a place to get the DPL 12 or an alternative? Adire seems to be out until mid-march.

    Maybe the Parts Express 12" Titanic would be close? I guess I need to compare the specs on the two.

    Colin, I thought the SAE matched closer to the Shiva.

    What do people think of the LAB12 by Eminence? Folks on DYISubwoofers indicate that it is very similar to DPL12?
