and look at the PB13-ULTRA in the 15Hz tune and then add 6dB to the numbers, and then compare them with the sim provided, it will show you how the 15” SDX 18Hz tune with a 1000 watts driving it compares to the ULTRA 15Hz tune. I have room to add more power to the SDX or tune it higher, (more output) but this works for me in the room I’m in. We are able to use larger enclosures due to no shipping considerations. My cost $50 since I have everything on hand over the years of building. If I were to cost it out (considering the 15” SDX was still available) around $8-900. If I were to build a second sub, that would cut the cost in 1/2 for the second due to opting for using a pro amp running each sub off of each channel.
This in no way is to downplay the ULTRA, (I have had 5 of them in the past) and are great subs. Pro's and cons to consider. We never count our time over here in DIY. Many of us would be very hard pressed to come up with a finished project looking as good as the ULTRA also. The SDX driver is what I would call a SQ driver like the ULTRA. The 12" SDX costs what some popular 18"s do. Very heavy driver like the ULTRA also.
Thanks for that link Steve, Was very helpful.
Quick browse through the diy comparisons and i like the look of the 15hz charts of the Re Audio MX18D2 MX 18, RE Audio XXX, and the Mach 5 UXL-18. Aesthetics Are a big plus and very important to me as i find the Piano Black SVS i own right now gorgeous so with that said i dont mind spending some extra cash on a nice cabinet, preferably with rounded edges. I plan to take the cabinets to an auto repair place and have them shot with piano black for that professional look. Also love the metal grill on my SVS anyone know of a source for something like that for a diy build?
This shows the highlighted areas open to my sub(s). Ceilings are 8ft and is quite a big area as the stairway has full 20ft height.

I ended up with a box 22"X 22"X 20"deep, not that much bigger than my SB13. I don't regret my choice, the UXL has ton of bass and it's a huge step forward when watching movies compared to the SB13. And according to DataBass, it should also do better than your PB13 Ultra.
I see you're in Canada, don't forget to check the shipping costs and brokerage fees if you're buying drivers from the US. Mach 5 audio are based in Canada and shipping costs are included in their prices.
You can see my build here.
Thanks Niavlys, I notice you came from a sealed unit prior. Iam a little worried with what iam reading about jumping from a ported to a sealed but the sealed is so much more enticing as its smaller and more plug and play. Im a little intimidated by the thought of tuning. Heck ive owned my svs for a year and am too afraid to go into anymore measurments than chucking the port foam in and slapping it to 15hz.
Because i like pics and chances are you guys do too!Edited by hybridfive - 12/7/13 at 8:03pm
