Project Description:
the idea of the project was to complement an existing sub i have in my system. I am currently running a previous 12″ sub design in my home theater and wanted to get just a little extra “boom” in my set up.

Design Goals:
wanted to achieve a tight yet not over bearing “look” of the unit. wanted to keep in the same mindset as the previous unit. the first is cherry wood this unit is black. the idea was to have a seamless flow not only in the loo but also to complementing my Klipsh Atmos step up. it needed to sound a seamless part of the
system and not a “add on” that was noticeably obvious.

Driver Selection:
i went with a Dayton II 12″ Classic sub woofer . (no longer available) it has the tight bass response i was looking for . not and over excursion but had good timing response when called upon remotely. no extended reverberation. and has alot of overhead (turn way up with little distortion)

Enclosure Design:
again my design is the classic look of most subs, yet i did a lot of box work (finishing) to give it a stealth look. you wont immediately notice the box is there because it blends well int the setup. the box is a ported design with very tight construction well braced with 3″ port. will need to modify because of the air movement i have very slight port noise.

Enclosure Assembly:
took my time and did all cuts and joining together over a period of time (4weeks). was in no hurry for this would be in my living room and wanted it to look good. i have a workshop at my job so all tools needed are readily available. construction went well.

Crossover Design:
no crossover . i use a Dayton plate amp list below.

i was able to achieve the clarity the look and the performance i was after. after a period of break in time it looks and sounds better that i had hoped. i keep things for a while so this will be with me for a long time. my next idea is to build a 15″ same concept. till then ill just enjoy the fruits of mu labor. peace!

About the Designer:
have been a parts express “geek ” for well over 15 years and enjoy building speakers just as long. i have built everything from towers to satellites to surround speakers and everything in between. not an “expert” by no means but TO ME my projects are expert. which is all that counts.
