[QUOTE="Toxic Tuan, post: 6486018, member: 558678"] Hi guys, Please take no offense in post but let me state my opinion. designs of pure enclosure and subwoofer TS parameters are very useless. 50% of the enclosure design revolves around the cabin/evirornment. 30% Revolves around application. 10% includes the personal preference of the listener and the last 10% is dependent upon theory. I've designed enclosures that was tuned to 70 hertz and the end result was an RTA-ed perfect linear flat response down to 25 hz due to the applications and environment. There are no current market available software that can calculate this. I use my own software that I've created to account for the factors involved. Pete from PWK Designs has an astonishing software that accounts for response in the time domain with particle collision theories that goes way beyond any software available. In all honesty, I would assume that everybody can do basic designs using WINISD, BassBox Pro, Leap, etc. I would call it calculating. But I wouldn't call that designs. Designs require extensive knowledge of the entire system with the emphasis of it's application. I'm expecting that every so called designer should get 100%, +/- 1% error round off, accuracy with this challenge. However, my proposal to a true challenge would be designing a subwoofer enclosure with one specific subwoofer that will would be measured in one vehicle. Then the design would be subject to the RTA for accuracy. This is a true design challenge. Tuan [/QUOTE]
