It must be something scandinavian to chill out that way, I've been partying and BBQ-ing like that for three weeks. The macaroni is very suitable for that, it produces great sound from nearby, but from 50 meters away you can hardly even hear it...

The ball speaker idea seems quite nice! What drivers will you use?

I really like PVC pipe, they also have 120 degree knees, maybe simpler to use than the balls....I've been thinking of using them to get a better 'spread'....

Hi v-bro,
Here's the housing for a very similar 2" PVC amplified speaker I was going to make.

I'm trying to shrink the sound system down, so it's even more portable.
I'm building something different now instead.

...and here's my outdoor friendly system.
I built an amp6 basic inside one speaker, that powers both.

Hey cool!

I definately believe in collective consciousness now!

(conscienceness )

What drivers were you planning for the PVC model?

I'm using Monacor SPH-30X, great little gems they are really. Really modern, light (150grms!!) and durable materials, magnetic shielding. They have sensational sensitivity too (at least 87db which is ultra for a 3"). But they sound best with a slight notchfilter IMO...

My macaroni seems to produce real bass (you can feel it in your stomach from a few meters distance!) Most people are really impressed, even some hifi fanatics....

I used rainpipe PVC, it's cheaper and thinner thus lighter. I never planned it to sound really good, the drivers really are way overqualified...

I had to cut the basket to become round to fit in the PVC pipe, than I used silicone glue to mount it and seal it off AND make it waterproof! It has been playing in the rain several times without any problem.....

I designed it to fit on a bike of a friend of mine, but it seemed very suitable for lots of other applications, By now I have built eight of them....

I have two Hi Vi A2s, that I rounded the baskets on.

We're working along similar lines. I really admired your first tiny amp32 in the diamond plate enclosure. The small size compared to the power of that amp sure changes what is possible.

That Monacor looks like a winner. Too bad they are hard to get here.

Yes, like I said, collective consciousness...

That Hivi driver looks nice, but the specs don't really turn my crank. The 78db/W/M sensitivity and poor lower frequency response is what I'm referring to...

The SPH-30X is small and light, so might be worth the shipping cost....

I ordered them from http://www.bmm-electronics.com

By the way Pekar, what is it you're building instead of the Pekaroni?


May we know?

Parallel projects once again, v-bro.
Here's a sneak preview of what I'm cooking up. Those are 2" drivers.

Hmmm ... make it of a single chromed steel pipe bent around 60 degrees inward in each end and angles 30 degrees up. Then make a black anodized alublock (or even better a solid rubber block) with iPod dock capability to rest it on, and you have a potential megahit selling product.
