For audiophiles who pursue the great sound, this 5” W5-1880 full range speaker driver is a good choice. It not only maintains good characteristics of 3” and 4” series drivers, but also has better performance of low bass.
Sensitivity of this driver is 88 dB. It is easy to match amplifier to generate good sound.
This floor standing speaker is also a back loaded horn design. Not like 3” and 4” are bookshelf design,. It needs longer port and larger horn outlet diameter. It’s a great full range enclosure suggestion design.
