[QUOTE="Art Welter, post: 148050, member: 52"] Re: No compromises front loaded double 18” cab You don't mention what math was used, that sounds like too much of a difference for the math to have been correct. I have found simulations to be perhaps 30% off on length depending on the actual port shape, location, and entrance used, so I always build long and cut down to the desired tuning for a prototype.
