I have 3 1.1ft cabs loaded with s2010s based off of Duke's initial project. I really enjoy the sound of that speaker/cab. Before the price of Neo went up, it was a fantastic speaker for $75. It's still worth it to me at the doubled price, but only because I know it's a cab that I will use all the time and it suits my needs. I always go back to the sound of it. I went with 3 to get the SPL that I might need from time to time (2.4ohm total), and to spread them around where I need them in the house, practice locations, etc. Mine is based on a gutted Ampeg portabass 1x10 cab (Im still searching for one more, btw). I removed the crossover, pulled the horn out and put a port in without hole cuttings mods, and changed out the stock driver for the s2010. It takes about 30 minutes total. It's under 19 pounds now, btw. It's considerably lighter than the stock cab. Not the most efficient use of money, but I like it a lot.
In my non-scientific testing compared to a SVT-210AV, it's different. More bottom end extenstion, but still growly and very punchy. I think it actually extends a little higher than the svt. Just about the same volume acording to my iphone SPL meter, but maybe slightly less total power handling. They were within 1dB difference. Sounds fantastic in the house! I keep an ear open for speaker stress, but I usually just use my Ampeg PF-500, or a Mesa Walkabout. If you can score a used one in good shape, it's a no brainer for what you are asking for.
Good luck! It's a great project!
