Drivers

One of the fundamental differences between these two speakers is that R700 is a 3-way design whereas R600 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker. R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz. On the other hand, R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz.

R700 has a frequency range of 38-38k Hz whereas R600 has a frequency range of 43-38k Hz. With a minimum frequency of 38Hz, the R700 can go significantly deeper on the low side and provide stronger bass compared to the R600's min frequency of 43Hz.
