Hi Josep, I wouldn't recommend that you design your own monitor unless you have a LOT of experience. However, building a pre-designed kit might be a good way to go. Here's an example from Zalytron. The Audiom TD5\Focal W Cone at the bottom of the page http://www.zalytron.com/photos.htm Thomas

To echo the illustrious moderator, Designing "real" speakers is non-trivial, and I speak as someone who has done that as a consultant in the past. It definitely gives you appreciation for those who design them for the major firms. As for Beyma, they are good company, and make a large number of OEM drivers for professional live sound speaker manufacturers.

I serched on the Beyma site and found "Enclosure Designs Catalogue" http://profesional.beyma.com/ENGLISH/recursos.php so it will be a kind of "Kit" to construct... the choose I have is,with the 12"woofer and 1.25" tweeter what size for the mids 5" or 6.5" ?
