It is exactly what i had done with the rear porthole of my speakers knowing that each speakers is a potential and an actual Helmholtz resonators...
I redesigned the cross ratio ratio from now a bundle of various necks lenght and volume/ versus the interior bottle volume , the result was spectacular in bass recuperation but on all counts too ... I redesigned the wave guide of the tweeter in a specific geometry and dimensions to accomodate my listening position ...
Generally the designer had three choices : an internal costlier labyrinth or an external unesthetical one, or only a tube inside straight or bent ... They almost all exclude the internal labyrinth because of the cost to design it properly and built , and they exclude an external one for evident esthetical and practical reason and cost too... This is why our speakers are perfect rectangular boxes... Cost and esthetic and pragmatism not sound qualities ...
My 150 bucks active speakers are so good i bought a tube preamplifier and now imagine a top speakers sound , miniaturize it , and it is my balanced sound on all acoustic counts, instead of being jealous of top costlier speakers, i almost pity them , those boxes now answer to my needs but with no spectacular defects at all ... I dont even need a sub with a 4 inches woofer ...
Acoustic principles rules the gear first as just said erik_squires not the reverse ...
Merry christmas to him and his family ...🎄
@roxy54 Being a speaker builder, I can say that while no speaker is 100% ideal as both ported and sealed, it does let you tune the bass in very important ways, especially if you are using a sub.
You don’t have 100% the control that a speaker builder does, who would know that an optimally flat ported speaker has more volume than an optimally flat sealed speaker, but given room boundary reinforcements, the ultimate judge of which is best can be you.
