Eventually I'd like to add a second one so I have one for each monitor. My lovely lady bought me the driver for our anniversary. The driver is a CSS SDX10 and it will be going in less than a cubic foot of airspace. I believe the dimensions came out to about 12.5 x 12.5 x 10.5. I just got the driver today so now I'll be able to figure out bracing and what kind of space I'll have in there. It modeled well in bassbox pro and should be able to get pretty loud, but we'll see what it looks like with distortion. I have high hopes for it with the XBL motor since the thing feels like a cinder block. Reactions: Rickster71, BMXTRIX, Adam and 10 others

Once that dries I'll bring the driver down and do a dry fit to see what kind of room I'm working with for stuffing and bracing. Given the size of the box I'm guessing I'll probably be doing an H style bracing so it doesn't take up much airspace. Reactions: psbfan9

Just straight from driver open air? Click to expand... Correct. It's just a habit now that I check every driver to make sure the FR looks like it's supposed to open air before I start building the box. I usually take a couple measurements close mic'ed and then run sweeps, tones and CEA bursts (since REW added them) and then take another close mic measurement to make sure everything seems kosher. All of this is done at 2.83V or less.

I mean who cares is sub plays to 1khz typically Click to expand... The only reason I played it up that high was to see what it's high frequency potential could be. It's only a 10 incher so I was wondering what it might look like as a woofer where it might get crossed as high as 200+hz and would then need a smooth response to at least 800hz. I would still need distortion and off axis measurements, but from what I took it looks like setting things up for those measurements could at least be interesting. I can't leave well enough alone My plan is to get another one eventually so I can have one for each monitor and then use a miniDSP to cross the monitors over to them. I don't know where the crossover point would be, but it's nice to know I have a wide area where I can cross and have smooth response 2-4 oct above. Once I get it in the box I'll have a better idea just how high it'll go for sure, but so far with the open air measurement it looks good. Reactions: BoredSysAdmin

I noticed the out of spec driver because it didn't measure as it should have once it was in the box and the other one was that first subwoofer. If I had tested the sub before I built the box I would have known something was up and I wouldn't have had a gigantic empty box sitting in the middle of my living room for a month and a half. So now I test it all, since it doesn't take long and is easy to do. Reactions: Adam

Tomorrow I'll bring the box up and drop the driver in for a dry fit. It doesn't look like there's enough room to do the bracing I was thinking of, but I have a new idea that should work Reactions: Adam and psbfan9

There will be a little bit more, then lining the walls, then getting the internal front baffle pieces glued and finally dry fit the front baffle. Hopefully by then the terminal cup will be here and I'll be ready for a test. If the test goes well then I'll glue on the front baffle and get to work on the outer front baffle and trim and I'll be halfway home. Reactions: Grador and psbfan9
