  • Noah's 8's tweaked a bit and finished with some rough pine

    So I hesitate to even post these on here with all the great wood workers/builders and more elaborate projects... long time lurker and first time project poster. I had a pair of Dayton 8" classics sitting around for literally the past 10+ years. They'd made it through 2 separate house moves. Decided I better do something with them before it was too late.

    Started with the Noah's 8's project, then did the original tweak of the crossover from Chris Roemer (though he recommends a further tweak beyond what I went with -- I went for the parts that were in stock at the time which matched his drawn up XO).

    For the tweeters, I switched to the shielded versions because they were on sale and I knew if I wasn't happy with these, I had a project in mind that would use the shielded version.

    I had some 2" vents already (again, been sitting for 10+ years) so I just cut those down to the appropriate size after recomputing the values... I know they're a little small but for my normal use(s) I don't expect (and haven't had) chuffing. I moved the port location down to about the 1/3 area of the cabinet as well.

    I kept the cabinet volume the same, but changed the dimensions slightly to end up at 36" tall since I'll eventually be building a tall TV stand that same height so these will match that.

    Used 3/4" MDF throughout... most likely inadequate bracing as I only have 1 window-ish brace. Then, I wrapped the top and 2 sides with the "paint grade" pine from Lowe's. I like it because it's rough and knotty and hides my mistakes well along with any bumps and bruises they'll receive over the years. Finished them with Ipswich Pine stain and 3 coats of poly. The black face and back were black primer then 2 or 3 coats of the Rustoleum Textured Black.

    This was my first project to use my new router and circle cutting jig stuff.

    I like 'em. Look like they belong in a ski lodge. Do you like their sound?

      Yes. I don't have any real measuring equipment... but running a frequency generator through them... things seem very smooth. I am not hearing any noticeable gaps or spikes in response. They're not boomy... but the response is there. So like Daft Punk's Solar Sailer (from Tron)... the bass line doesn't get any quieter on the lowest notes... just nice and clean all the way down. I was scared mid's would be too soft in a 2 way like this, but I don't really find anything lacking. But I've always suspected that anything you build yourself always sounds "better". Thanks for the great (and easy) XO design.

        That's true. Just like how your car runs better after you wax it.
