Thanks for the details. The IDS25 array would be a good DIY'er for a novice speaker builder who could marry inexpensive drivers with an equalizer and yield good results. It could be DIY built using 3" Hi Vi or Aura drivers for less than $1000 plus the boxes and say $300 for an equalizer. But for $18,900 per pair this comnmercial speaker isn't a player for most people.

As you report, your Selah Audio line array that you built beats the IDS25 at both ends of the band. Plus it costs a lot less money.
