#20 Presonus Eris E3.5 2nd Gen: $99.99 Amazon eBay

Pros: Rear-panel bass and treble controls allow broad correction for desk and wall placement. Erin’s second-generation Klippel measurements give a -3dB point around 69Hz, so the speaker has useful upper-bass reach for its size. Its adjustable balance is more flexible than a fixed-response budget desktop pair.

Cons: The stock response spans 7.2dB from 300Hz to 5kHz and has a strong rising trend of about 1.27dB per octave, emphasizing treble over the midrange. Preference scores of 1.15 standalone and 3.81 with an ideal subwoofer indicate major tonal problems beyond bass extension. EQ may help, but a subwoofer alone will not make it neutral. Output and port-modification results from reviews of the original E3.5 should not be assumed to apply to this second-generation model.

How it compares: Just above it: M-Audio BX3. Just below it: Midiplus MI3 II - $39 more.
