Dayton 10" DIY Sub Build
« on: July 05, 2016, 02:58:12 PM »
Decided to give a Partsexpress subwoofer bundle a try - for 200 bucks and some sweat equity not much to lose and a lot to gain from trying to smooth out the dips in response from 20 to 90 hertz in the cave.   For your entertainment some pictures of the build and results.

The cabinet comes like this - precut by some computer-controlled device that makes extremely precise cuts:

Goes together like a jigsaw puzzle:

I chose to veneer it,  not necessary - the finish is smooth enough that you can use textured paint to do it.

(the pic shows I need to do some minor stain touch up in the veneer-to-baffle area)

The combined response, collaborating with my Rhytmik FV15HP,  met my needs (crazy suck-outs at 30 and 80 hertz gone):

The Dayton sub runs out of power at 25 hz (it is a sealed box) but in-room it gets help from the side wall to drop lower.  On the upside it is very precise,  tight.  Building these things is, of course, a blast.   The Gorilla glue is a big help compared to regular wood glue,  recommended. 

I am driving the sub with one channel from an iNuke 3000DSP,  using a couple of PEQ filters to smooth things out in that channel using DSP.   The other channel is driving Dayton bass shakers that I turn on for movies.

Regards,

Pepe

Forgot to add specifics about the 10" driver - a Dayton Ultimax 10" dual voice coil sub:

The voice coils are wired in series to get the impedance up to an amp-friendly 4 ohms:

That woofer looks very beefy. Always reading good things about the Dayton speakers, but you never know if it's coming from someone thinks Sounddesign or Aiwa sound great or a more serious listener like yourself.

Those Ultimax are killer subwoofer drivers. I had designed a huge box, 4'x8'x12" for a PAIR of the 15" Ultimax. They sub was used as a couch platform for second-row seating. It was phenomenal. Nice build!

thanks all...  I am very happy with the performance of this Dayton sub so far,  need to monitor to see if it is durable (will watch the Lian Neeson Taken trilogy as a test  8)).   On the other hand, if it is going to fail it probably would happen during the first few hours of coil-heating.  Will see.

On a separate but related topic:  check out this cool design for a hideaway transmission line sub:

They have it hiding under a couch, but I bet it would be an awesome riser for an Expedit filled with records.   All that weight would really anchor it.
