Old ears and damaged hearing. Looking for design characteristics for center channel speaker that might help me with dialog clarity. Currently have a 5.1.2 system using Elac Debut 5.2 bookshelfs and center across the front driven by a Yamaha Aventage RX-A660 avr. 80% TV/movies. Decent system but I am investigating what would make a step-up for L/C/R starting with the center speaker. Working with EQ and room acoustics in parallel. Willing to spend around $2500 for front L/C/R speakers IF the improvement is noticeable. First pass thru the options indicates that the higher-end centers are typically 3-way designs with a smaller mid-range driver but, of course, there are pricey 2.5-way and 2-way speakers around as well. One feature of the 3-way concept is the ability of the cross-overs occurring outside of the normal dialog frequency range leaving the mid-range to handle most of the vocals. The SVS Ultra is one example of this design that receives decent reviews. A surprisingly inexpensive speaker that also follows this arrangement is the Emotiva C1 or C2 and these two are also well supported on numerous forums/reviews. In a 2-way arrangement the Chane A 2.4 is popular too. Anyway, any comments or suggestions on my investigation or experiences with specific speakers that I should consider ?
