#75 Dayton Audio MK402X: $97.99 per pair Discontinued Parts Express eBay
Older model: the Dayton Audio MK402 (ranked lower, estimated 3.2/5).
Same family: the Dayton Audio MK402 (smaller bookshelf, ranked lower, estimated 3.2/5), the Dayton Audio MK602X (larger bookshelf, rated 2.4/5) and the Dayton Audio MK442 (center, estimated 2.9/5).
Pros: A compact, inexpensive 4-inch passive pair with an upgraded crossover over the original MK402. ASR measured good on-axis smoothness of 0.193, excellent sound-power smoothness of 0.125, broad horizontal coverage to about +/-60 degrees, and a very well-damped bass alignment Q of 0.24. Measured bass extension of 63.0Hz (-3dB).
Cons: The response tilts bright at +0.20dB per octave and predicted in-room smoothness is a poor 0.18. Estimated in-room extension is 52Hz, sensitivity is low for a passive speaker, and the 4-ohm impedance asks more of a small budget amplifier. Discontinued.
