Some Pictures,













And lastly my totally makeshift test enclosure for my 2 nd65-4's with dayton dta-1 and music through my phone courtesy of Amazon Cloudplayer. Worked great until my phone battery gave out!



Also forgot my earplugs so I figured something in my ear was better than nothing. Can almost feel the damage occur to my ears when routing the mdf otherwise.

Beautiful work man. I bet you can't wait to hear them! You're in for a world of delight.

Re: on Sale - $55/pr (drivers & XO)

Got to my dad's place about 11am today and worked til about 9pm including clean up time. Got every panel cut and rabbeted for a pair of nano neos and a pair of the ntn's. Got all driver holes cut. Got ports for all four cut to length and got them epoxied in. I was able to incorporate several things this go around that I didn't do on mine. Namely not cutting all the way through on the ports. I will route out the rest which should make a much nicer port round over. Also used the drill press to cut all the driver holes as opposed to using a jig saw like I did last time. Everything is just that much more precise. Will post up some pics shortly. Still have to glue everything up. So Chris you can move me from thinking about it to doing it!

Only way to make a port

Mikers,

Yeah I wish I had done that on the pair I made myself. I know I picked up that method here off the forums, just couldn't remember who to thank. So much good information here it's hard to keep track of it all!

Chris,

I really want to build a pair of these, even without the woofer on sale, it looks like a really inexpensive full-range system. I need some little speakers to run from the little amp I just finished. These seem easy and have some bass. I haven't really read this thread until a few days ago--don't know why not.
If the wife gives me the okey-dokey, I'll be ordering parts soon. But I have limited access to tools, so they'll look a little rough compared to others' creations.

Thanks for making this public and for all the hard work on it. I can't wait to build them.

I can't wait to see you build them! Out of curiosity, what little amp did you finish?

I can't wait to see you build them! Out of curiosity, what little amp did you finish?

It's a little amp box using the Sure 2x100 watt amp board. It's using a 30V power supply. I have also used the Sure volume encoder board and I threw a switch/light for both the power supply and the amp itself.

Link to more info is here: http://techtalk.parts-express.com/sh...highlight=tomz

I only have two little RS75's in a cardboard box to test these with for the time being and I really want to see how the amp sounds on some real speaks. These speakers Chris designed seem like they will be exactly what I need, cheap, small, and producing actual bass! The cabinets will be ugly, not what I'm used to producing, but at least they'll produce full range sound. I'm in between houses and don't have access to my arsenal of woodworking tools.

Nice Job on your ntn towers, I like them a lot. I'd build the mtm but I don't have any room at all to play with. My wife even said when I told her the size they were going to be... "That's kind of big". We live in a very small room for the time being, so space is at a premium! Are you going to build a pair for yourself now?

And yes, the price is a bit depressing -- not that they're not worth it, but come on PE, have a sale for crying out loud! (I'd buy a bunch of them if they dropped the price to $20 or under! ;) Really, they ought to make these into a one button click "kit" at least. I wonder how something like this doesn't make it into the project showcase? I'm pretty sure the drivers will be around for a long time since they're pretty recent.

Re: on Sale - $55/pr (drivers & XO)

I was going to make myself a set, but after selling my home theater, I realized I could make the statements monitors with the budget I had so that's what I will be doing. It still puts a big smile on my face to listen to the ntns I built though. They just sound so awesome.

Ill check out that amp.

Re: on Sale - $55/pr (drivers & XO)

Alright, I'm in.

Just ordered all the parts, a few terminal cups and some heat shrink tubing to bring my total to $100 and change. I love free shipping.

Woo hoo! I'll have some tunes within a few weeks Lord willing.

Since you don't have your tools, you could just build some "temporary" cabinets. You should be able to slap them together before the parts arrive and be ready to go. Surface mount both drivers (you probably wouldn't flush mount them even if you had your tools as the the tweeter is a simple press fit and the woofer recess wouldn't be round). The woofer comes with a gasket already attached. Four screws for the woofer and a bit caulk for the tweeter, and you'll be playing tunes as soon as you get the crossovers assembled.

That's what I was thinking, cheap temporary cabs. I was just saying to my wife that I don't have to wait until the speaks come it to begin. It's just a simple box. Also, I plan on doing another crossover on a stick type of thing mounted to the input terminal like I did on my RJ's a few years back. This is going to be ugly though, but I'll be glad to just have tunes with real bass in my room. Thanks for the encouragement!

I was talking with my father last night and he said his old Sears (real old, and I'm 40 and remember it being downstairs as a young kid) radial arm saw was dead accurate for miter bevel cuts,

...so I may try my old cabinet building standby... mitered edges for top/bottom/sides, and a rebate for the front and rear panels. I used to do this all the time when I first started building speakers. It makes glue up a cinch because the inset front and rear panels help to square up the top/bottom and sides. Perfect box every time. He has a small compressor and a brad nailer I can use in lieu of clamps.

I'll use his sheet metal deck el-cheapo table saw to make the rebate for the front/rear panels to sit in. I wouldn't use it for anything percise, but I can eek out a 3/8" x 3/4" notch out of a piece of board without too much trouble.

Actually, I have an idea for a super-cool curved cabinet for these speakers, actually the ntn's, curved cabs are so much work for something so small as the neo nano's, not that their not worth the effort, but if I'm going to bother making something curved, I want to see it a bit bigger if you know what I mean.

I have to check out his equipment though to see if it's accurate for real or just 'close enough'. I may just end up building temp boxes for now depending on how this works out.
Man, I need a house bad, it's been 8 months since we've first signed the contract to purchase the house we've been trying to buy, and over a year that we have been living in my parent's spare bedroom. It's really getting to me. And my cat's not too happy about it either.:eek: (projectile furball vometing :eek::eek::eek

Thanks again for the guidance,

My dad had one of those, too! It would be dead accurate for square bu*t-joint cuts, too. ;)

Well...better late than never!! Here are the photos of my NTN's.. got them put together last night and just now got the time to post photos... Let me know what you think! Thx - Chris

Re: on Sale - $55/pr (drivers & XO)

You can pick them up used for dirt cheap (radial arm saw). Cuts well but dangerous and big
