well i am tired of the speakers we are using now for the tv as they're more or less shot from abuse when i was young. so i have decided to build some new ones.

here's the plan i got a pair of Aurasound NS3-193-8A and NT1-204-8D on the way and all the other stuff that is going to be needed to build these. the dimensions are going to be 10"h x 5.5"w x 7"d with a 1"d x 4.75" port. the box is going to be constructed from 3/4" mdf and the baffle is a 1" hard wood(don't know what one yet). i plan on painting the box black while having the hard wood baffle clear or stained.





i am going to be using a Linkwitz-Riley 2-way crossover at around 3800hz. the tweeter is getting a 2.2uf cap and a .67mH inducer and a L-pad with 4.5ohm and 6.5ohm resisters. while the full-range woofer is getting a 2.7uf cap and a .67mH inducer.

well guys RED OAK won.

FedEx dropped off all the speakers and crossover stuff. i nearly fell out of my chair as the door bell rang around 9:30am. in all the time i been ordering online i never have gotten a package this early as they normally come after 7pm and late as 10:30pm.


well i just got back from the store and i am now $120 poorer as all the special tools were $20 a pop. i also started making the boxes.









so far so good. should get done with majority of the building and into the sanding stage late tonight.

more picks t come

Might consider re-designing the port some. If you can, make it a LITTLE bit larger in diameter (obviously keep the same tune, so the length will change too). Also, make sure you bevel the edges of the port as well with a router or something (or get rounded port tubes off Parts Express). If you have a flat edge on your port, you'll get some pretty bad port noise. That's also why the port should be a little bit larger in diameter.

Otherwise, looks great.

EDIT:
Nevermind, I see that you already planned to round the edges. I would still suggest a slightly larger diameter though.

I'da built thewhole thing in MDF and put a hardwood veneer or thin piece of your choice material on the front. Less resonance.

i was playing with a larger port but i figure its not needed as its only a 3" woofer. if it was any bigger i may of jumped to a 1 1/8" or 1 1/4".

I need to learn to read apparently. Didn't realize it was only a 3" driver. Yeah, a 1" flared port should do fine....as long as its the right length.
