The model-type is my former Yamaha NS8390 3-way floor standing speakers with 8″ drivers.
I purchased the pair of floor standing speakers at Anson’s in Trinoma in 2013 along with Mordaunt Short 10″ power subwoofer to complement the low frequency of my audio set up.
Although it is an entry-level, this pair model is still famous in North America as a cheaper pair of floor-standing speakers below $200 but performs well comparable with top-grade speaker brands in the international market.
This pair of floor-standing speakers system boasts a 3-way bass-reflex system with 20-cm cone woofer; 10-cm midrange, and 2.2-cm high-frequency balanced dome. Its frequency response is from 36 Hz to 27 kHz with 220 watts maximum input power.
It weighs only 11.7 kilograms per unit and has a dimension of 262×290×266 mm.

However, this is a 1-channel driven pair speakers. It cannot be set up to bi-amp. Moreover, this pair is very independent without a need for subwoofer. It can also be used for a conservative stereo set up.
As my personal preference, I paired this with my old Yamaha RX-V73 audio-video receiver (avr) in practical 5.1 set up.
