Dynavox 4" Fullrange
The big trend in modern audio is to use small fullrange drivers in compact cabinets for desktop/monitor applications. With this 4" fullrange driver, it is absolutely possible to do. With a frequency response of 50Hz - 20KHz, using a single driver per cabinet is absolutely possible. The 6 ohm voice coil also makes this driver versatile for mobile audio applications as well.

    sweet find!

    Overall: 4.5 out of 5

    I used these in a design I dubbed the cigarellos due to the enclosure dimensions. 1.7L with an fb of 90. With a little filtering, these have a smooth response from 90 to 18k. The 3rd order distortion is nearly 60db down at 1k and stays very low throughout. great little driver, very easy to listen too! I highly recommend this driver for a desktop build!
