Joer, que mala suerte, lo que nos temiamos, una mala configuracion del subwoofer. Han respondido esto:

Hello Victor

I am sorry I never got back to you yesterday but we had a public holiday yesterday. e have now extensively tested the two subwoofers that were sent back and they both test OK. We have to overdrive the subs to make them make unusual noises.

I feel that you may need a bigger sub for your room and expectations, and feel that the only way we can resolve the problem is to offer you a refund

Please let me know your thoughts

Regards

Tom

No soy muy bueno con el ingles, pero usando traductores, pone que despues de hacerle las pruebas ven que el sub necesita un mayor tamaño y como son una empresa seria nos ofrecen la posibilidad de un reembolso.

¿Que hacemos David?
