As sculpture it's more Henry Moore than Michelangelo. And if Henry Moore's sculptures speak to you, this one sings and plays music. There have been some pretty off-the-wall speaker designs lately, but this one is truly courageous.

Okay, I haven't listened to it – it has only just been released in the United Kingdom where, according to Sir Thomas Beecham, the audiences "may not like music, but they absolutely love the noise it makes", and production is so limited that it's unlikely I'll get a listen any time soon. But given the manufacturer, I'm prepared to go out on a limb and say the noise it makes will likely be entirely satisfactory.

That manufacturer is Metaxas and Sins, based in the Netherlands, and comprising Kostas Metaxas and his two sons. (Sins – get it?) If his name is ringing a bell, proceed to Go and collect $200: you're a hi-fi enthusiast. Kostas once ran a business in a trendy inner-Melbourne suburb building boutique amplifiers, although the term he used was "bespoke". Indeed, in serious hi-fi circles he is still remembered with a degree of reverence, and anyone who owns one of his creations wouldn't part with it for quids.

Now he's making speakers too, and his Macrophone studio monitors, sitting atop tripods straight out of HG Wells, are gorgeous. This new one, a floor-stander 1.7 metres tall called the Siren … well, beauty is in the eye of the beholder so I'll let you make up your own mind about it, but I didn't even have to ask my better half – I doubt she'd live in the same postcode as a pair of these. But to be fair she has problems with most speakers that attempt to double as art. And there are plenty of them lately.

Now you want to know the price, but before we go there I need to explain a few things. Just accept for the moment you can't afford a pair unless where you live is described as leafy and despite your four-car garage the Ferrari is still out in the rain.

First, production. Each Siren is made of seven pieces of aluminium carved by an imposing machine called a computer numerical control router.Given the aluminium starts as a solid block, this is not a quick process. In fact, running 24 hours a day the machining for one speaker takes eight weeks, so production currently runs to 10 pairs per year. But you can always order titanium rather than aluminium.

Also, how is your high-range hearing? If you like smooth, beautifully defined highs that shimmer, you'd better order the diamond tweeters over the standard ones. You can also choose between leather and gold-leaf finish, and one called automotive; goodness knows what that is.

Okay, prices. The Sirens start at $145,000 a pair in aluminium with ceramic drivers. The automotive/leather/gold leaf finishes add $10,000, and diamond tweeters will add another $15,000. And if you want Sirens in polished titanium start again at $330,000.

Kostas says he hasn't got an Australian distributor yet, but he's working on finding one. Meanwhile his two sins, sorry, sons, Andreas and Alessandros, live in Melbourne and can deliver and install. But why not pop over to Amsterdam? I'm sure Kostas would be happy to give you a listen. The last time I was at his place he was an Elton John fan and while I'm sure that's all changed now, you may want to take some of your own music with you just in case.
