b/c of your box design there is more back pressure behind the sub thats closer to the port. this same thing happened to dave dasilva and his audiobahn sub last year and same thing happened to jeff and his dd subs, all from that box deisgn. the sub thats closer to the port/located over the L of the port blows faster than the other one.

you're right, that is why Im workin on a slightly different variation of that box... you do have to admit...those boxes are working well and did gain SPL over the previous boxes used... it's not a free world... gotta give some to get some

Guys... c'mon.. I thought we were smarter than this.

You can't just drop equipment in, see a gain, and say it's better.

If you change gear you really have to re-do all of your testing from scratch.

Different box/port sizes as well as different power levels and frequencies will work different with every type of equipment.

The only way to be able to say one sub is better than another is to work on some equipment for an extended amount of time until you really have maxed out the capabilities.

actually... yes

some equipment is just better than others in street application... this is why we do test over and over
