If you’re using a small end cap, the vent area needs to be at least 1/2 of the driver area. Otherwise you end up with big peaks in your response.

Make the vent the correct size and the response curve evens out.

So you saying if the driver cone is 2.91" with an area of 26.6 then my vent should be at least 13.3?
seems right. i said area because it could be differently shaped vents or multiple smaller vents.
Well, what I did with my endcaps didn't seem to cause any fuckery but it's also closer to aperiodic or IB than anything. It solved the problem I was having that was causing the gb25's to ring and not be happy crossed below 800;)And no one that has listened has mentioned any fuckery in the midrange. When tuning they didn't need anything drastic outside of a nudge here and there to flatten them out between 300 and 4000.
I ended up trading the Hertz 700.3 for Focal K2 Power Slim 100 KRS. It only seemed right after buying the Focal Utopia Be 6.5 from Skizer :)
I was wondering if someone would be kind enough to verify these speakers are still best IB? I believe they are.
