Yeah, I'm about to make a craigslist ad to sell all my Polk speakers so I could build 4 more of these and perhaps a center channel as well.

Got to this too late. Lol. He had a mild smile on the whole time like an "oh my goodness I can't believe this. This is so cool." He'* not one to make huge theatrical reactions so video taping him would be a bit dull. He absolutely loves them though, and I do too.

After listening to them in his room for an hour and coming back down to my $1150 Polk RM40T'* and $300+ Monitor 40'*, I almost couldn't believe the difference. They undoubtedly sound MUCH better. They sound richer, fuller, and you can hear each instrument and vocal sound better. You'd have to compare the two in order to understand what I mean. Its just incredible how much better they sound.

He played some good songs that he'* been listening to for a very long time and as we were listening to them, he said he could hear things that he never heard before in the songs. These are just so accurate, so rich, and so well balanced its ridiculous. The...imaging and the sound stage is just insanely good. I seriously have no words to describe how good these sound.

That being said, I am building 4 more, and I will be taking orders this time. They will be based on the exact same design, just different sizes (with a stand built in), and either flat black, gloss black, or any other color I might feel like painting them.

Oh, and my current Polk speakers are for sale.

Built a new driver based on my own design, for the first time! Granted, I had a lot of help with the crossover (ok, someone designed it for me), but otherwise this is more of my design than anything I've ever done, and I'm happy to report that they sound amazing. Very good value for what I spent on them.

Nuance TW5-2LR Tweeter: $3.75
http://www.parts-express.com/pe/show...number=279-061

Aura NS35-255 Driver: $4.50
https://www.madisound.com/store/prod...oducts_id=8992

Crossovers: $10.64 per

Total for the speaker pair: $37.78

I bought over 10 so I only paid $4.25 each for the drivers. I also added a round push-type terminal for an additional $1.10 per cabinet.


For this design, I decided to use poplar because its light, its cheap, and it will stain very nicely. However, I know its not as dead as MDF so I decided to go crazy with this project. This project involves 20 separate cuts of material per cabinet.

Doubling up each panel with two 1/4" thick panels does a few things. First, it allows the panels to be more dead due to overlapping wood grains, since I would otherwise have parts of the wood on a 1/2" piece that would be more dead than others. Also, the generous and even distribution of wood glue between the panels adds more rigidity. The other thing is that these will look superb with roundovers, as you will be able to see 4 different wood grain panels with the 1/2" roundover bit I'll be using.

Crossovers are from this thread:

Mounting the drivers was a big challenge because there is technically no usable flange width at the N, *, E, W points, so I had to mount them on the much wider ridge below and use some weather stripping to seal them up. I will be trimming the weather stripping so it looks better later.

I got these put together quickly so I could use them during a bonfire we had today so I didn't get to take a whole lot of pictures, but I put a good amount of stuffing inside and they sound great. They definitely got loud enough to have to yell over in our back yard on my Lepai amp, and while the bass isn't too great, its definitely there and its enjoyable for casual listening. Honestly, at this price point, you can't have everything and they are a great value for what they are.

More pictures to come once I get them rounded over and stained.

Is anyone even reading this thread? I can stop posting in it if nobody really cares...


...

Almost done! Just need to stain them and get some of my open cell egg-crate foam on the walls that I can reach since they resonate a small amount. Got them stuffed nicely with polyfill, and they sound just as good as they look. Can't wait to hear my mom'* voice on the phone when I ship these out to her. She has no idea I'm even making them.

Awesome! I'll carry on. BTW, I'm having such a damn good time right now.

Cold beer, 80 degrees and windy, smell of "big storm is coming" in the air. Quite relaxing.
