From La Rochelle/FRANCE... Hope my english is OK ! I've been using "4xSub 302 and 8x802 with 4 amplifiers BOSE 1800-VI" since 1998. Proud to be sound engineer for rock-jazz-blues-reggae or even classical music'groups all along, with audience to 2,000 people max, i first heard the F1 system on the 1st of July 2018. Waoooouh ! On September, i decided to sell my whole system, then immediatly bought 2 F1 Sub + 2 F1 812. Too happy to keep on the roads, at the moment, people are very surprised to hear about it ! And me too... I'm only waiting to use it outdoor with nearly same audience to compare. A bemol ? 2 handles are missing on the sides of the 812 to put them easily on stands, cause i prefer to get it higher than using the supplied mount. And it's a pity we can't put straightly the 812 directly "on" the Sub. However, I did it last W.E, but the 812 was not totally secured, so I strapped them. Endly, I don't like the "hole" between the 2, first for the "look", but also we don't need to separate them when we use it on stage !!!
