Hi Joe,
- Based on your own experience with 288s & multicells / I would encourage you to grab the pair of multicells available to you. ( One reason for this, is that to duplicate what you heard & reviewed , you'll eventually want to own a pair of Altec 288 drivers ) . BTW; What model 288 was reviewed ?
- You'll need to make a pair of entry adapters / a la the Dukane 2" type. These were used to enter into VitaVox multicells ( OEMed in N.A. for Dukane ) .
- I would also encourage you to stick with 2440 diaphragms ( instead of 2441s ) since you're using a tweeter above the mid horn .
