I’ve owned many 2-way monitors (totem model 1’s, totem mani II’s, totem arro’s, usher mini dancer II’s, to name a few) and they all had their drawbacks. Every one of them I used a pair of subwoofers (Rel) and there were drawbacks to this too, Rel recommends running the main speakers full range which puts a lot of strain on the smaller woofer. In case of the mani II’s, with the isobaric woofers inside, the speaker was so inefficient I was running them with 1000 watt monoblocks part of the time. So with subs, the sound was more full but at a cost.
With 3-way speakers, you normally have the right size tweeter with the appropriate size midrange spec’d together while designing the crossover to send the lower octaves to the woofers. These will play louder with less breakup/distortion. I know you can buy a 2-way/2.5-way with larger drivers but I’ve never liked anything over 6”/7” for the midrange, and some of the smaller 5” midrange in the Ushers sound fantastic.
I purchased a pair of the ESS speakers with the Heil AMT in them in the late 70’s. If it wasn’t for the patent on them, you would have seen ma y more of them during the last 4 decades. 1 hell of a driver.
