yeah well as a kick sometimes a bass bin at others
If you want people to feel the bass then a reflex design is probably best as you get the most air movement per decibel from those.      errrrr yes wtf?

Hi there guillaume03, do you by any chance have the designs for these cabs? with all correct measurements, like the looks of these cabs and been told there good kick cabs. 

If anybody has any similar 15" kick or sub designs please let me know? 

Many thanks in advance, Daz

Did anyone draw this up for particular driver & perform HR sim ?

Seems there is a difference in opinion, on cab response.

I would rather a peak at 125hz and eq out than have to add eq. The other down side is it only plays down to 60hz, making it not usable as a part of a small system. The other down side is this design is not very loud spl wise, making it very hard for this design to keep up with an 18" scoop..... play around with it in horn resp lev, at this point I would not even take this design to proto type stage build..... I no 4db down at 125hz don't seem to bad but its 8db down at 200hz on the rta also when simming in horn resp sim at 4pi in stacks of 4, this will give a better idea of how it will perform in a mono stack with scoops....

a plott tells only one half of the story, a plott can look good but, wont give us any indication in to tonality of the speaker. BHP cabs suffer from sounding honky if taken over x freq, but the plott can indicate a smooth response. Ive built, designed and listened to so many bhp designs in my quest to understand how and why they work, and more importantly how only a very few companies have managed to get there bhp designs to play higher....

below lev is a plott I took yesterday, mic on the floor 5m infront of stack, 2 plots were taken at the same time. Sound card was calibrated, mic used was an ecm8000 with measurement files for mic calibrated.
 
apart from the obvious one, One of the measurements had an internal filter turned on in my rta software (oops) can you tell what plott is what, and why both plots look different, yet the same.....
 
should of said source material for this plott was a deep house tune (cd) and was a snap shot at x point in the song

Think what's needed here, first and foremost, is the HR input data & plot for this cab.

Will then be possible for the community, to objectively assess this cab, and compare with HD15, with a number of drivers.

That will be guide of which drivers (if any) will be optimum, dependent on individual requirement.

However, should be noted a number of people have already built/heard this cab, and liked the sound.
