Yes I've built those RS 8 and you can see them in this URL. They are good + speakers , and if you decide to build them then beware of the stifness of the enclosures , lots of bracing is best and I would recommend 1" MDF for sides and back and 1.5" for the front baffle . I built the ported version as I did not want to add subs from the begining ( budget wise ) but if you need the lower octave then go for the sealed and add a pair of subs and you will get the best you can at this price I am very positive about that . I am now planing to build 2 Citrine subs (you can see them on Rick's site )as I definitely feel the need of the lower octaves .Dont hesitate to ask any question concerning those monsters . JP Haggar
