I loved *both* red boxes.
That gave me an idea: now I want to also build a portable "docking station", with, say, 2 x 5" or 6" speakers + battery powered amps , slightly larger than my Netbook, so I can use it as a "Portable DVD player", only it would play cool downloaded AVIs instead.
How's that?
PS: my 2 x TDA2003 PCB can be wired either as a bridged or stereo output, so both configurations are possible.

JMFahey,
The TDA2003 is a class A/B 10 watt amp correct? Have you considered T amps? The batteries will last longer and you get more power.

Hi Guys,

Mine doesn't qualify as a true Boombox as it runs off house mains. Nice thing about that is you get to have some decent power. The Toolbox has Extremis 6.8 woofers running off a plate amp, and the Wharfdale mid basses and LG drivers drivers running off the Tascam mini PA amp. Seven compartments in total.

Both the Toolbox and the Pentagon use RCA for inputs.

It's extremely loud.

I was gonna make 'er pretty but I noticed a twist in it after glue up, so I had to change plans and do whatever I could. Toolbox is the first thing that came to mind.

I like what pegodk has done with his too.

Nice design Cal. I see you are a fan of plate amps for woofs. Where are the ports for the woofers or are you running them sealed. Thanks for showing us pics of the wood under construction, a picture is worth xxxx words. How many watts on each channel?

Since it haven't been brought up yet. You might want to read my Boomintor thread

The Boominator - another stab at the ultimate party machine

Just google "Boominator" and see all the different boomboxes people have built based on this design.

You might also want to read the development thread I have recently started for a MINI version.

http://forum.speakerplans.com/boomin...opic74610.html

Enjoy.

Thank you, yes so easy to control the bass depending on the listening enviro.

Sealed, both in one chamber. Plate amp in its own.

Woofers share the 125 watt plate and the Tascam is 30wpc.

I think the Boominator might be the best option for him.

Or the MINI, as that's what he's actually seeking. And the MINI is dirt cheap. Doesn't even break the impossible $150 budget limit by a mile.

Here is a build I did and it sounds awesome. Quite loud, and I hope it's somewhat waterproof (Everything sealed with Silicone).

Box; $18.88 (Amazon)

Speakers; $40 (Amazon)

Amp; $20 (Amazon)

PSU; $12 (Amazon)

Charger/Controller; $10 (Ebay)

So everything with a 12V SLA Battery is around $115. I haven't completed this one yet.. But I have a smaller version that sounds GREAT!

I also incorporated a 12V Charger, and it will charge my Samsung Galaxy S3 AND output Audio through USB, so there's only one cable to plug into the phone.

I have a simple 12V Plug for input.. The external PSU plugs into it.. The controller/charger charges the SLAs while providing power to the AMP.. Really cool system.
