yoli Posted June 21, 2010 Report Posted June 21, 2010 Hi everyone I'm Joan from Bulgaria So I started a low budget SPL project and I stoped at the box build. I have two Pioneer TSW 121 SPL powered by single SPL GRLA 5500D. Can someone help me with the box because I don't know what kind of box I'll need for optimal results with thees subs.

yoli Posted June 21, 2010 Author Report Posted June 21, 2010 I'm sorry but can you describe it more in detail. Cause I'm not very good at English but I know technical terms but I'm not very good at Abbreviations.
