Hi Guys,
Well it's that time again - time to start another DIY build.
This 5th build will have influences from the lessons learned from my previous builds. Some ideas worked great, some didn't work at all!!
This will be my 2nd biggest box to date. Remember my V2.0 box with the big white Sony drivers? (avatar pic) This is my benchmark box as it had simply beautiful sound. I'm planning on replicating this successful build but with improvements.
To ensure the V5.0 will have the same awesome bass, it will also have 8 inch drivers but the cabinet width and height will be reduced slightly. The depth of the box will increase though to maintain the correct volume of cabinet air to allow the drivers to punch deep and low.
I'm using all brand new components for this build. If this box works well, I plan on making more for my little band of locals who like to buy my builds when they're finished.
Ok, firstly I needed to find a very rare thing indeed - an 8 inch, 4 ohm driver. The ever reliable Lepai LP-2020A I use for my builds really needs 4 ohm speakers to perform at its best.
After searching everywhere, I finally found these reasonably priced 8 inch drivers from an Aussie seller. They are 4 ohm with 92dB sensitivity which is ideal for this project.

Next, I needed some sensitive tweeters that could keep up with the drivers. I chose some very nice Krix silk dome HiFi 4 ohm, 91dB tweeters with matching Krix 2 way crossovers.

I'm using a high quality Sure Bluetooth 4.0 receiver to maintain high quality tunes:

Ok, that's the easy bit. Now to build a box to house all of this new gear:
I always use thick 18mm premium grade structural plywood for the top, bottom and side panels for strength. On this build, I used 12mm on the front and back panels as well as the internal walls instead of the 18mm ply used in the V2.0 box to reduce weight and increase the internal speaker cabinet air volume.
As the new V5.0 drivers are heavier than the white Sony 8 inchers, it's important that the new cabinet be kept as light as possible.
The length of the cabinet will be just over 70cms so it's still got some size to it!
Down at the local hardware shop grabbing sheets of premium 12mm and 18mm plywood:

Fired up the table saw and cut the sheets to size. The top, bottom, sides and front panel glued and clamped:

Internal walls glued and clamped:View attachment 28242
Rear access door cut from rear panel then rear panel glued and clamped:View attachment 28243
Dummy fit of speakers:

Speaker holes cut and speakers test fitted:View attachment 28245
Next steps: sanding, routing, sanding, sanding, sanding, sanding and then painting!

More updates to follow.......
I'm really looking forward to hearing this one fire up for the first time!!!!
