springbrook, the tsms you had were quite inferior to the latter models in virtually every respect. so...do you like a recessive midrange or a continuous sounding one? it will have bearing close to the wall. the tsms are set up for bi-amping as you know and work incredibly well if you keep the tweeter wire less than a gauge of 15. more than that will increase the tweeter output and unweight the sound.
hope you are well.
