I ended up having to make the port down firing because I didn't have enough internal clearance between the flare and the baffle if I had the port rear firing. Also, this allows me to place the cabinets closer to the wall.

I like the way the cabinets are looking! People are going to be asking you what brand and where can they buy some when you are done.

Thanks! I sure hope so. I certainly wouldn't mind making more of these!

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.

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.

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'* 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.

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'* 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.

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 finished the second one last night and had a listen to both. I couldn't believe the sound. These sounded better than the RM40T'* I bought a while back, and those have a $1150 MSRP. The staging is excellent, and every detail is perfectly reproduced. Nothing short of spectacular. I kept forgetting that my sub was turned off. I ran a few bass tests tones through these and they can definitely play musically down to 32hz. My wife said these sound like my car in regard to bass output. I seriously had to check my receiver'* settings 3 times to make sure my powered sub was off.

The details are very good, the response is very flat with no undesirable peaks, and they sound VERY large. The sound fills the room and with such elegance and accuracy that you really have to hear them to believe it.

My only gripe is that they're not very sensitive by nature so you have to crank up the volume to get them a bit louder, but that doens't bother me as they get PLENTY loud when you push them and have absolutely no distortion at high levels.

I so don't want to give these away. I'd rather scrap my entire Polk Audio Monitor 40 based home theater and use these two instead, but I built them for my father in law so I have to give them to him tonight. Can't wait to see the look on his face.
