[QUOTE="Nicco Cerve, post: 216061, member: 14070"] Hello, Sorry i just saw the recent developments. I'm currently working on [USER=11669]@Robert Lawson[/USER]'s model. I'm modeling it as a single horn sealed back cabinet, instead of 4 parallel woofers in a vented enclosure. So i changed Ap and LPT to Ap1 and Lp and divided all volumes by 4, while switching to 1pi. The horn design itself is good to me, with filtering and eq it has quite good response up to 400-450 hz, which is where i plan to cross over to the DCX. I have to need to cross over at 100 hz since i have a 2 way bass solution, but sealed back modeling clearly reduces the low frequency extension. I just added the thoath adapter to extend response in the higher range. the 4th and 5th image are freq resp and displacement at 80V input for the single driver (800W). Xmax is 6,8 mm. I have no idea how to implement the new throath adapter in a real life desing; I tested a bunch of different drivers and i ended up choosing the one Robert simmed, mainly because i live in Italy and i'm already using B&C products, so it's easy to get them. I'm looking forward to import the 3d model on Akabak as soon as i have time to sort some thing out with the software, and build a protopype as soon as i sell out my old midtops. I'm actually quite new to modeling, but hope to get better results soon [/QUOTE]
