At last, it is finished! I know there are about as many of these kinds of threads as there are sonosubs in the world, but I just HAVE to share. Sorry. The EBS shiva is simply fantastic. It sounds great! Just like you read on so many DIY threads, having a good sub reveals tons of material that you never heard before in certain movies. It sounds much better than the old sub did with both movies and music. My expectations were very high. My expectations were met. I went into this DIY sub thing with two preconceived misconceptions: that larger drivers cannot reproduce higher-frequency bass clearly and that sealed subs have substantially higher sound quality than even well-designed vented subs. I'm very glad that folks like Jack Gilvey steered me in the right direction. My shiva sounds better crossed over at 120 than my old 8-incher did. I've found that many things in the house (and components of the house itself) rattle at certain frequencies. It's fun to be playing a test tone that you can't really hear, but know something's playing by the rattling of various objects here and there. I have a good start on my rattle-prevention campaign... vases and decorative stuff are easy, but I don't know what I'm going to do about the window panes. Speaking of test tones, I (for the first time) did the "walk around the room and find the peaks and nulls" thing. My placement of this sub is terrible. There are huge peaks and huge nulls all over the place. I want a better living room shape!! Not having giant openings to other large-air-volume rooms would be nice, too. I was running it waaaaaay hot at first (hey, new toy ya know) and I bottomed it on LOTR. Eeep! That's an ugly sound. I presumed I was bottoming my old sub when I heard lots of distortion, but I guess I wasn't. The 8-inch POS was making LOTS of unwanted noises, but not THAT noise. I hope I didn't damage my brand-new driver! It still sounds fine. For future reference, is there any way I can inspect the driver to make sure I haven't damaged it? Anyway, I'm absolutely pleased as punch. If you have a more normal sized living room without giant openings to every other large room in the house, I don't think you'd have a problem with bottoming. I can listen to most material as loud as I care to listen with no problem... it's just LOTR. Here are some pictures of the build process and the finished sub... http://boxybutgood.com/temp/sonosub/ Building a sub is a lot of fun. I'd like to thank Hank Frankenberg and Mark Hayenga for their help!
