Thanks Peter. I’m dropping my current design and picking this up.
I’m going to follow the recipe to the T. The box design sketchup you made, thats for the 40degree splay?
Can you share the Xovers youre using all the way up (675,900,3300)? Im most likely going to use a Venue360, doesnt have the filtering your ASC48 has but it will do the job.
Now I just need to sell these 14NDL88s to someone, and switch gears. I think a 14” driver is probably pushing the limits of 675hz crossover point for lobing.
The HPL is one heck of an efficient driver. I’m comparing it to the 12NDL76 and the NDL brings equally (1db more 300-900hz) more sensitivity and a 50watt increase of power with little to no increase in price. The 88 version adds 1/4 more to the cost (and weight) and while it handles twice as much power, the sensitivity comprimises by almost 3db so, its somewhat of a moot point.
I think the NDL76 will be a fine fit as is the HPL. Cant beat the db/w vs weight numbers on a flyable box.
B&C released the passive network for the Coax also btw.
Thanks and again, your work is just phenomenal.
