[QUOTE="Bratishev_Artem, post: 8760038, member: 683837"] In the car, the design was chosen BP-4. 4th order bandpass. What is BP4 - one side of the speaker is closed in a sealed volume, the other side plays into the camera - after the camera is a port. Despite the fact that there will be a cage in the caddy, the whole machine is subject to the terrible influence of parasitic resonances, so all the panels to which it will be difficult to get to after welding - we use the best material for these purposes. STP Massa Bassa is a sandwich of polymer (mastic) and bitumen layer. EATH, the material works both as additional stiffness and quenching due to viscosity. + layer of aluminum foil. It is difficult to work with it, the application of the material implies heating the material and the knowledge of the installer (what to do with it) and labor-intensive rolling, but efficiency is above all! the effectiveness of the material, especially after a day, is above all praise We rolled it up where we saw a need for it, let's go for the metal! PURCHASED: Profile 30 * 40, thickness 2mm + I-beams and a huge amount of cutting wheels, wires for welding, consumables and other trifles ... After that, we invite a "welding engineer" for a consultation on rigidity and a discussion of the importance of applying knowledge from strength materials ..... [/QUOTE]
