Hello guys, have a question: And I have played with the idea to sell my sub and to buy a new one. However, it should not necessarily incur big costs again. It would be best to sell the current sub and buy a new (or used) chassis for the money. I would add the cost for the construction of the box. Jetz is the question what to ask for for a ZX-12 Dual…and then what to ask for in the price segment for other Pro I thought maybe to build a bandpass that plays through the ski bag opening. But I didn’t think about it yet and am therefore quite open to everything. However, the pressure should not necessarily suffer from it. So 140db should be able to come back with the “ZX”… Listen to 3/4 Black and Hip Hop, to 1/4 Techno and Trance. I dare to build the case myself. I just had to have the size calculated somewhere. As an Antrie b provides a sound stream Rubicon 1002 with Maxxima900 and 2*1F capacitors. The Rubicon is 1Ohm stable and then delivers about 1000Wrms Then I have a second question: And I tried it a little bit. I turned the sub times and measured the sound pressure. But I had the greatest pressure when the sub direction of the boot flap played. If he played in the direction of travel it was much quieter. So it makes sense to build a band pass through the ski bag od he should end the whole direction tailgate in the trunk? Hope I didn’t forget any information, otherwise there is still a lot in my signature Soo, then I want to hope for a lively participation… Greeting Funtiger83
