the box Pyrit 212 Sub A

Es un altavoz espectacular en cuanto a buen sonido y presión sonora.
Su relación calidad/precio es inigualable, incluso superando a marcas de alto nivel.
Lo he utilizado en mas de 10 sonorizaciones en un par de meses, tanto de grupos de pop-rock, jazz, rumba-folck, etc, como en situaciones de disco movil con dj's y se ha comportado con un rendimiento profesional magnífico.
Solo puedo objetar que no son ligeros, pero si tubieran 2 asas mas en los laterales verticales se agradeceria para su mejor manipulación.
En definitiva, recomiendo encarecidamente este producto y no defraudara por su buen acabado de material, robusto y sus puntos fuertes, sonido pro a un precio asequible.

Los tengo en conbinacion con unos JBL 625 EON, tengo una disco movil para eventos como bodas, comuniones...
Los tengo un par de años y aun sin un problema de fabricacion.
Pesan bastante y poco manejables, es lo peor.
Buena calidad de sonido, les falta un poco de potencia para mi gusto, de pegada vaya, pero por lo demas bien.
Si tu presupuesto no te llega para mas, como me pasaba a mi, no lo dues, compralos.
Si puedes algo mas, pasate a unos doble 15" y si mas aun marcas de gama mas alta.
Lo ideal para mi seria un sub de JBL, pero se me va mucho.

I don't care what brand or speaker size of single sub box you've been working with so far, I can promise you that this thing beats them ALL !!!
You can point at any other brand that costs double the price of this one, and this thing will blow each and every one of them clean off, without even breaking a sweat.

I have this speaker as a set of 2x10" satellite +1 sub, and I play on open air venues for up to 200 people, and sometimes playing in bars. I play keyboards and striking a lower note is giving me the shivers now, it sounds so powerful! Up until now when I bought this sub, I finally stopped being worried about not having enough power. From the first night I've put it on stage, it blew my mind how much power reserve it has, and how low and loud it goes. I pushed it quite hard, until the point that my pants where shaking as I was 2 metres in front of it, and that thing still had plenty more to give before making it clip...IT'S INSANE!!!

Being 41kg. is not a feather, but still is much more compact than any 18" sub, and I suppose it gained that extra weight in form of structural rigidity, because 132db of sound pressure will and can mechanically destroy weak and poorly designed box, so it needs to be as heavy as it is. Still, the weight doesn't stopped me from buying it, even though I have to move it every night, but since I have a trolley to move it around, that's not such a big issue. Having to deal with the hassle of caring that heavy box every time, is well worth the pleasure to hear it roaring behind me.
And it also comes pre-drilled for wheels installation, you can use the box as a trolley on it's own.

Pros:
Very soft but punchy bass.
Various presets to match it with your satellites at the back panel.
Drops very LOW powerful.
Comes prepared for installing wheels of your choice.

Cons:
It would have been better if there where just holes in the middle of the side panels, instead of handles closer to the one end of the side panels.
Causes blurred vision and extreme bow movement when played loud ;)

Resume:
If you have any doubts or prejudices about not buying big brand names, you can leave those worries away now, and you'll save yourself some beer money, without compromising in sound and quality...Thomann has put some serious engineering thought and know how in building this truly outstanding box...hands down to them for this one!!!

Update after 7 years of use:
I've had an issue with crackling speakers after about an year of use, but it somehow miraculously fixed itself on it's own shortly after it appeared, and I still use that sub to this day at least 3 times a week.
