New Baby Boomers
 
3 Attachment(s)
Here are some photos of a couple mew portables. The cases are vintage French made clarinet cases cr. early 60's. reinforced with 1/4" board to give them more stiffnes.
One has a pair of Aura NS3-193-8A and a modified Sure 2024 amp with a Li-ion 12v battery for power. The second one have Tang Ban W3-881SJF full range drivers with a small low pass filter and a Sure TPA3122D2 amp with the same Li-ion battery pack.
I find these are really fun and challenging projects and would like to thank all the folks on this forum for all your help. :hohoho:

Nice! How do they sound, and how do the Tang Band compare to the Auras? I choose between exactly those two drivers for my build!

They both sound quite decent for such a little box. The Aura/2024 has a nicer full rich sound with a little better bass than the Tang-Ban/3122 combination. The Tang-Ban/3122 is quite a bit louder but a tiny bit thin. All and all I am quite happy with the way they turned out. Friends who have heard them are quite amazed by the sound and volume they put out. I have one more case to work with- not sure what I will put in it. I'm pretty much limited with the 12v battery supply.

OK that is what I expected! I went for the Aura for that reason.
I must say that your builds look really great, I guess they turn a few heads.

I have thought of making one with a 4 channel amp split to 2inch full-rangers and to some "sub". Like an active crossover. Then the sub can be used to fill out the low end at low SPL, and then run the full rangers only when battery time is an issue. But I'm not sure if that is really a good idea, just an idea I have.

I really like the little Aura's. I have a pair in a mini Onken cabinet. They sound great with a ODAC, 02 pre and modified Sure TPA3122D2 amp. Makes a wonderful book shelf set up.

Love it!! those cases give them a nice retro look.

Congratulations, they're cool! I have something similar in mind so this is good inspiration. Unfortunately the speakers you're using are not as widely/cheaply available in Europe and shipping+taxes is generally a deal breaker for me when buying from US so I'm currently looking into alternatives. Tang Band W3-665SC is on my short list in order to stay low budget (can be found for 10) but I'm not sure how they compare. Logitech have used them with success in their computer speakers though so it's supposedly a tried and tested driver.

Update to the above: I managed to find the Aura's for a reasonable price (about €16 here in Denmark) but the same shop also has Monacor SPX-32M for around €20 which could be just as interesting. In any case the odd looking wooden phase plug would be a neat match for a retro style box like yours!

Cool looking cases.
But not much in the way of driver separation (stereo) and What keeps fingers. toes and Golf balls from destroying those cones ?
