DIY sub to best SVS PC13-Ultra - Page 4

Still not sure if I am going to do dual opposed or 2 single boxes yet. Drivers should be here on Friday so maybe I will get inspired when I see them and make up my mind sooner.

I think the wife will help make that decision when she sees the size of the drivers and box plans. Several pros for sealed: No high pass filter, no port chuffing, smaller box ect. Probably just being lazy but did not like what modeling was showing for port velocity and such. With Inuke6000 for just the 2 drivers I should have some decent head room. Another thing that made me consider sealed was that data-bass has measurements for SVS PB13 ultra as well as a sealed DIY build with the dayton 18's. The single sealed 18" dayton had higher output at 10hz and 12.5hz and across the board except SVS was better at 16,20 and 25hz. With 2 18 dayton's the SVS gets destroyed as far as output is concerned. We will have to see how sound quality is compared to SVS.

The speakers and parts showed up today. Wow those are really nice looking well made drivers. They are also huge! If nothing else at this point they look loud just sitting there. Hope to start on box or boxes Monday. Amp should be here on Wednesday. Hoping to have something ready to hook up by then.

If you are trying to mimic the SVS, you are going ported right?

I've been doing some M&S on this scenario, and I keep thinking 2 x 4" ports about 29" long for a tuning freq of 18 Hz is just about where I'm at. That's a 22x23x32" box, and the ports will need a 90 degree elbow. I'm wanting to use thin-wall PVC "sewer pipe" but it can be hard to find. The regular schedule 40 PVC is 4.5" OD and eats up a lot of internal volume. (about 0.6 cubic feet!)

A single 6" port might be nice but it would have to be even longer. About 33". 1130 cubic inches displaced

And don't accidentally wire it 2 ohms just be careful it's not as fault-tolerant as more expensive amps i.e. you can break it. That's the other thing I know from 'personal experience'. Not the amps fault.
