design stage

 I used inventor 10 to design the A-10's (our schools standard design software). the original enclosure was going to be ported but when i got round to buying the actual speakers they turned out to be designed for a sealed enclosure. the enclosure was designed to a 6 liter capacity to suit the speakers. the original designs were for 12mm MDF which would resonate very badly, hence why i ended up using 35mm and thats why the end product looks somewhat distant to the original design. the name "A-10" came from the angle at which the enclosure leans at (10deg) and the "A" was used cause i was attempting to create accurate audiophile standard speakers.

construction stage 

cutting and shaping the speaker were somewhat easy tasks compared to the arduous work of gluing, sanding and routering. i used a homemade router compass to create stencil circles to guide the router around when cutting the speaker holes, although the still ended up pretty lumpy. 

the soundproofing mat i used on the enclosure is a thin mat of tar  with a layer of fluffy fabric over it. attaching these sheets was pretty simple , they were already pre-glued; so all i had to do was cut em up and stick them on. 

i used 2-pac marine epoxy with an added black die to glue the cases. this was probably the most frustrating part of the whole job, considering i only found out halve our clamps were completely screwed by the time i had put the glue down. but i got the job done in the end.

hours were spent with the belt sander and a gas mask  to make the box nice and square again, really frustrating stuff. i went through 1.5 cm of MDF at the bottom of each speaker making it all level again. but in the end it was all worth it when the cases came out nice and square thanks to a bit of builders bog.

finishing stage

orinonaly i used a 2 part bumper repair paint- just so i could get the assignment done on time. the finish was a mat black sorta look. but eventualy i got them re-painted in a gloss red, which i am very pleased with. i got the job done by a local kitchen painting place at $60 a speaker, which is a pretty sweet price considering they also had to remove my previous paint job, and sand all the surfaces to perfection.

the crossover was a simple single stage setup, I'm still not entirely clued up on the whole thing so i got mike to help me out there. the sound they produce is somewhat sharp and surprisingly pure, they need to be assisted by a sub to get some lower end to their sound.. so i guess thats next.
