Ok, got the tiny speakers kinda put together. I need to re-make the baffles for these guys, but I wanted to listen to them. These are Dayton ND65's with 2.5" drivers.
Keep in mind, I'm still going to round the edges and stain the oak.
These things sound absolutely amazing with the 20w x 2 Lepai amp. The fidelity is uneblievable. They won't win SPL competions obviously, but they sound a LOT bigger than they have any right to sound. The frequency response is absolutely awesome, and the bass, while not being very loud, is very impressive for 2.5" drivers. These truly pack a LOT of sound for the size they come in. I'm still going to add some more poly-fill and trim the cabinet depth by 1/2" to control excursion a bit more.

Yes . According to IEC panel standard measurement , 45° is even too low ,60° would be better . For a speaker of this size , well ...That's Xdream revolution's
task to determine whether or not those may influence somehow the sound .
Thick baffles that are not beveled, chamfered or opened up on the inside are audible. A very thick baffle acts like a short tunnel. You wouldn't mount a tunnel in front of a driver, so why have one behind the driver? A tunnel mucks up the midrange giving it a cupped or honky sound. Yes, I've done before and after listening tests. If one cannot bevel or roundover inside, then the next best alternative is o apply some absorbing material inside the "tunnel."
I contributed a small tips and techniques article on the above topic to audioXpress magazine.
I'm whole heartedly for thick baffles, but I prefer a very thin baffle edge in the proximity of the driver.

Got some more progress done this weekend on the towers.
I painted them with the 50-50 wood glue and water two coats, then sanded. I was amazed at how smooth they sanded after the wood glue got soaked in and dried up. With 400 grit sandpaper, it seriously felt as smooth as glass. I also got them almost completely primed. I put 3 coats on, and I have to put another coat so that I would have enough substance to sand down.

In talking to a friend of mine, I realized that these are perfect for an apartment. The reason being is that they aren't as loud as a 10" powered sub, but can still produce musical bass down to the high 30's with surprising volume. I have another guy interested too.
I have some pictures to post of recent progress. Got the primer sanded down, and started painting.
First coat:
Second coat:
They say practice makes perfect, and this is certainly the case here. Lesson learned: don't use brush on primer. Next time I'll be using spray on primer. While I wet sanded the cabinets to get rid of the brush strokes, some still remained and you can see them in these pictures. That's not going to be a problem with the next set I make.
On the bright side, I realized that each can gets me at least 2 coats, and I have 3 cans. I was expecting each can to last me only one coat. This is great because I'll be sanding between every 2 coats and that may do wonders in getting rid of some of those brush strokes, or at least I hope. I'm guessing that 6 coats of clear coat will follow as well if the clear coat lasts me as long as the black paint does.

You can use a small paint roller instead. Then you can buy a big, cheaper can of primer and cut down on the fumes.
LOL!
These are actually presents for my father in law for his birthday and as a "congrats for beating lung cancer (going through surgery and intense chemo" gift.
No, not to be used in a home theater. When i build myself a set, they're going to be black only. These will be used in his "office" to blast classic rock while he works and plays COD.
Got one driver completely done and I had to listen. My Lepai amp kept shutting down on me so I went to my room and hooked up my Yamaha receiver.
So far, I'm only using one of these since the second cabinet isn't done yet, and I have to say I am VERY impressed with the sound coming out of this one driver.
My father in law will be using these on a two channel amp and I know for a fact he will be nothing but truly impressed. The sound stage is quite incredible. Its incredible to believe that these are only two 4" drivers. Even with only one of these in a 350 square foot room, it fills the entire room with very detailed, excellent sound and enough bass presence to not need a sub.
That being said, I still have to hook up the second.
I just played Rag Doll by Aerosmith and definitely hit over 110db to the point where it was uncomfortably loud. I can't even imagine what two of these will sound like, but I'm sure they will be nothing short of epic. Finishing the second one will be the first thing I do tomorrow when I get home from work.

I don't know why, but I love that paint-job.
I usually don't feel anything when it comes to paint-jobs.
I'm building desktop MTM or TMM with the same NS4 and a neo-tweeter.
I'm not sure which is better for a nearfield application. Maybe I could even make one of the woofers fire out the back.
Any opinions?
I mostly think it's better to combine similar topics/builds in threads, but I don't know when it becomes "thread hijacking."

Jimmy,
If you have room for a small floor stander, then I have a design that might be worth checking. Your post prompted me to comment that my MTM mass loaded transmission line speakers have been duplicated many times over. I use the Aura NS3-193-08 drivers and every user have positive comments on this design. There is a long build thread on one of the Parts Express forums at:
Jim Griffin's Aura T-line 2-way
Check out that thread as it may be what you are thinking.
