Hello Diy

This is my first speaker project ,I have a habit of biting of more than I can chew when it comes to projects :xeye: :) .
This project has been going for a number of years now ,life just gets in the way more often than not . I'm also building the electronics from frontend to amps which doesn't help .Plus I have no real electronics knowledge :eek:.Plus the room it self needs a bit of acoustic treatment .I was a its all about the front end ,but over the years I feel its more speaker ,xover room interaction .

Any here's a novice approache to speaker design and build :) .

The design ,seperate bass cab's to the mid section so I can move them around and swap out the top section for a Synergy horn ,designed by Paul Spencer ,but thats another project :).

Drivers ,I've heard the Raven tweeters a number of times and I really like how they sound & they sound really nice with PHL's .Bought the drivers from Pat @ War Audio in Perth ,Australia . Pat has been very helpful over the years .

Cab's & Baffles

I wanted large round overs on the corners and a triangle shape cab ,so with toe in the cabs don't look as wide .Also hoping for less defraction on the edge's .
I looked at making a sub frame then wrap it in multiple layers of bendy ply .I found a supplier who would guaranty a 100mm radius with there ply .I was having a chat with a cabinet maker who also built speaker ,Andrew W. from Aslan Acoustic about my project and he offered to CNC the cabs for me .He also machined the front baffles ,which he loved doing :p not.I think 12 months latter the swarf was still appearing .

Cabinet piece's the jigsaw begins :).

Stacking to Glue

Talking to Andrew about gluing the cab's he told me to watch out for horizontal movement when clamping down to glue . So I made a jig to hold it all in position , if you know me I like making jigs :). To make it more complicated for myself I used ally dowels instead of timber ,15 of them .I hoping the alloy baffles & dowels will add stiffness but not alot of weight .

The rectangle section is set back and acks as a dummy baffle .

Gluing

Talking with Andrew about gluing he warned me about horizontal movement when gluing and clamping down . So I made a jig ,I like making jigs :) .
I also done a dry run stacking and clamping to see how much work time I had ,the epoxy glue I used has a 45min work time .The epoxy I used is designed to glue dissimilar materials . The dowels 15 of them are alloy ,I used alloy dowels & baffles ,hoping to improve the stiffness of the cabinets .

Another jig

One problem with triangle shaped cabs you just can't lay them on their back and work on the front baffle :( .
So I thought I'll make a jig for the cab to sit in so I could router the area where the baffle fits .Plus I wanted a new portable work bench something I could roll out side and work on .

Hmmm think we must be shopping for jigsaw puzzle speakers at the same shop... :scratch2:

Great looking project cant wait to see the results :up:
We must be :D ,I never did like jigsaw puzzles .
Amp case's each layer is made up of 4 pieces .
An externally hosted image should be here but it was not working when we last tested it.
