Drivers

One of the fundamental differences between these two speakers is that Prime Pinnacle is a 3-way design whereas the S50 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.

Driver SVS Prime Pinnacle Polk S50
Driver Setup 3-way 2-way
Tweeter 1-inch 1-inch
Midrange 1 x 5.25-inch -
Woofer 3 x 6.5-inch 2 x 5.25-inch

Prime Pinnacle features a 1" aluminum dome Tweeter , a 5.25" Midrange and 3 x 6.5" Polypropylene Woofer with a Crossover frequency at 300Hz and 2100Hz. On the other hand, the S50 features a 1" Terylene Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.

Frequency Response

Prime Pinnacle has a frequency range of 29-25k Hz whereas S50 has a frequency range of 33-40k Hz. With a minimum frequency of 29Hz, the Prime Pinnacle can go slightly deeper then the S50's min frequency of 33Hz.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Prime Pinnacle can handle a max power of 300 watts RMS from the amp the whereas S50 has a max power handling value of 150 watts RMS, 150 watts less than the Prime Pinnacle.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

S50 features 5-way post posts which make bi-amping or bi-wiring possible. Prime Pinnacle has a 5-Way post which doesn't feature bi-amping/bi-wiring.
