Do you have a suggestion for something decent, not expensive and easy to implement with the NanoDigi now they don't sell the Curryman?

Second test box glued. This is for one of the 15" midwoofers.
43 x 43 x 43 cm. 30 mm MDF, internal volume 50.65L. This will result in a net volume of about 46L. 2 per side, one 15" in each. Simulations below with Qtc 0,486 show that we are about 5dB down at 100Hz.

Since the crossover between 21" and 15" will be at 80Hz, I think this might work. Question is, what amp will do the job best. Time will tell
