Small bookshelf MTM with open back using Vifa TC9FD and tiny Dayton 3/4" dome tweeter ND20FD.
Sweet sound, highly recommended!
Of note, I use this speaker only from 150Hz and up, with woofer or subwoofer. I never load small fullrange with low frequencies. Distortion of small fullranges in general rises dramatically below 100Hz. This results in upper harmonics which were not present in the recording and only mask the true midrange and hights, muddying the sound.
