Thank you!
And thx others for sharing experience!
So i think i will go with LT and sealed box. I think thats the best what i can get from this woofer. Now is ih H frame,nice sound but linearity not good. It play only from 50Hz below.
Maybe i can giva a try with LT in H frame before i make big box.
One thing i dont understand with H frame. Sometimes it sounds better 30 cm from back wall,sometimes is beter 1 m from back wall. Is there any sweet dpot for H frame?
Its like a never ending box with distance from back wall.
I think i can avoid that with sealed box and get faster and more attacking bass.
One problem with LT is that the lower you go the more heat in the voicecoil. Pretty soon the electrical Q will be modulated to a large part by heat. The same is true under normal use offcourse, but to a much lesser extent. Under normal use, if dynamics compress, bass gets a bit looser, delay gets worse, unavoidable stuff but you can still liv with it. Is LT really really going to improve things given all that what follows from the much higher power dissipated? LT is a brilliant idea, in theory, but as I see it, requirers some pretty stiff numbers to be put into the equations. How to do that when, do to temperature, Rdc in real operaation, çan be 20, 40, 100, or whatever percentage off?
