Just to clarify some points.
The Monoliths are a different kit to the GR-Research Super Mini speakers.
The Monoliths kit comes with a dspMusikLCD or dspNexus digital crossover system and the parts needed to build the speaker system. This kit is not sold as partial pieces.
For the Super Mini passive crossover speakers, please talk to Danny at GR-Research and he will get you what you need.
Thank you for reading.
