I say upgrade/downgrade because although the TS-A1372R performs better than the TS-A1302C in some areas (upgrade), it is considered an overall less superior product (downgrade). For instance, the TS-A1372R has only a .375” dome tweeter (versus the TS-A1302C’s .865” Tetron soft dome tweeter). In addition, the TS-A1372R does not possess an angled surface for tweeter pivoting, nor 2-way external crossovers. The Pioneer TS-A1372R, however, does feature a 1.25” lightweight balanced dome midrange speaker, a speaker grille, and a considerably more affordable MSRP of $79.95 (versus $149.95).
