Excellent sound
Very moderate cost

Limited bass due to the cabinet size.

This new (2008) kit went together well. I have the Sonicap capacitors with bypass caps and the No Rez damping for upgrades, and the price above includes the kit, these upgrades, the cabinets, and shipping. The front baffle speaker cutouts are usually cut with a router and circle jig, and many amateur and pro woodworkers can do this. The crossover networks must be assembled on a board and the connections soldered, and this takes minor skill.

I like the sound. I gave the overall rating four stars because the speakers are what they are...really excellent monitors with limited bass. The bass is limited by physics, not by the design. Any 6.5" woofer in a sealed 0.5 cubic foot cabinet is doing great with clean bass down to (F3) 77 Hz, and this is very clean, accurate bass. The highs and mid-range are sweet and accurate. The bass is very good as low as it goes. A violin sounds like a true violin. A piano sounds like a true piano at both ends of the keyboard. Cymbals and the triangle are crisp and clear. Voices are great. I can hear the vibrato of the strings player and the singer. Blues and jazz have the drive I like. Snare drums are snappy. Imaging is good. The string basses sound like they're located behind the violas and cellos--which they are.

Similar speakers ported with bass (F3) to 55 Hz, but maybe not quite the sound quality--NEO-1X.

Note that the cloth grille fits this NEO-1X and does not fit the NEO-2X.
