Hi Mark,That’s a great solution for a simple ground stack rig. I have been looking at something similar using some Turbosound dendritic horns which were designed to array a bit like L-Accoustic’s Arc’s.Having the drivers recessed like you have will give you some gain. I would however be amazed if the efficiency of the DIY and your box are that similar. On the SIM the DIY has about 5 dB more … however after you apply the EQ to flatten things they should appear similar in terms of the input signal to the processor and measured output from the speaker (assuming the same crossover gain).The trick with the DIY is that the EQ where you have cut some of the peaks out is the extra drive you can give the speaker before you exceed its actual power handeling.
