Yes, that is why I use 95.3 for the SI, that is what it sims. If you look at the max spl charts from Ricci it is very close to that. The sims don't take the distortion and box size into account from Ricci. When I sim I use .707 for all sealed systems to equalize the sims. Ricci recorded 89.2 for a distortion burst test, the sim is closer to the max spl chart ricci has and using the SI vs the FiQ18 confirms this. Basicaly, the SI has a passing test at 10hz where the Q18 did not. However, the max spl chart shows an advantage at 10hz for the Q18 and that is what the sim predicts.
