I think this is a good approach. I've spent years tuning my 2-way and I really like where Iam at with it....I have a closet filled with enough gear to support a few 3-way front stages, but I like the KISS approach too. I remember reading on diyma, reproducing the entire frequency range with the least amount of speakers is key....but difficult. You need a midbass woofer that is comfortable going up higher than usual, and you need a tweeter that is comfortable going low enough to meet the midbass woofer, essentially eliminating the need for a dedicated midrange. The Esotar 650, and the Dyn T-380 have done that for my truck. Your amp rack is sweet! And those amps......produce ******!!!
