Talking Portable HIFI ( or somthing close )

Hi there Dear members of DIYAUDIO.


As Diehard HiFi lovers i think everyone has made atleast one solution for enjoying hifi quality sound while outside the house.

Class D amplification is interesting for this due to its high efficiancy, i know from experiance that portable valve radio's eat more battery's than anyone is willing to carry to there picknic.

What kind of solutions have you guy's came up with for that trip to the beach, battery powered shed amp or any other kind of portable hifi thing, please show it here so we can all enjoy and learn some things!

Ill kick it off then with my little ultra portable Class- T amp
At a minor 400 grams in alu housing pretty neat, but im still thinking of a good speaker solution ( any sugestions, more than welcome ) probably bass reflex, coz a TML will cause a bit too much size and weight.

Greetings from Shenzhen / Holland

Ah, but what about speakers? No good having a top notch portable amp without the equivalent sound reproduction?

Default Portable speakers

Aha! making a mini amp is less than half the challange, small speakers are hard to make, especially when your a bass head like myself.

So ive come up with numerouse solutions, among witch glass transmission line speakers alu housings and wooden housings.

ill show you what i made today, i found some 4 CM diam drivers 8 Ohms and 3 watts no further specs known to man, but for 5 RMB and it was the best looking i could find, Quality is very hard to find here.... Very hard

Anyway ill show you the result.

also the Glass mini TML ( 1" driver full range ) also sounded pretty damn good for the power i threw at it

I wouldn't take them to the beach if I were you

I like your inventiveness, they look pretty cool

I got my hands on one of those HiVi Swans t-amp jobbies and it came with some dinky 3" drivers in 5" spheres that sound pretty good but I bet they would sound better in your TML

I see that Vikash now sells those little Hi-Vi 3" drivers. I'm thinking of buying a couple and trying then in 'drainpipe' TLs.
