Yeah, let see what kind of monster it gonna be! 60l box isn't problem, i put the Linkwitz Transform circuit, so it gonna go down!

I have ordered rl-p15 2ohm DVC, and let see how good it is. I'm gonna do some transfer function magnitude measurements and thd measurements. Between christmas and new year i'm gonna build new box and at January new Linkwitz Transform and Linkwitz Riley 24db/oct lowpass filter. Before these i'm gonna use it in my old box. Is it ok if i do new box at 25-30mm MDF, put inside some 22x22mm sticks between "walls" and something sand/glue on the walls to make it more heavyer etc?

This is best transfer function magnitude that i can get. Is is ok? http://img383.imageshack.us/img383/2373/winisd24nd.jpg E: Have i just do something wrong, because i get over +0.0db transfer function magnitude @80hz on my simulation? I use Linearteam's WinisdPro alpha software. E: This is my old subwoofer: http://img383.imageshack.us/img383/2669/dyny2sw.jpg http://img383.imageshack.us/img383/2277/dyny28hv.jpg http://putfile.com/pic.php?pic=11/32113250975.jpg&s=x11

Is bessel 0.577qts and 50l ok?Think that it is more hifi than 0.707. Or something else?120hz lowpass@movies and [email protected]" costs about 425? with ship+tax.2 post because surfing Nokia5140i.

I live blocks of flats so im not using max power.Good sound is important.Mike says 15"is better than 2x 10".Room is 4x5m. How many db i could get @20hz?

I need subwoofer witch has more than good sound, tight, musically, not just same sound putting out. So i need a HIFI subwoofer I were looking 80litres sealed box with Linkwitz Transform circuit and Linkwitz Riley 24db/okt lowpass filter. -6db point to 15hz. My amplifier works better at 4ohms so 15d2 could be better than 15d4? I got 2x1200w/4ohms or 2x 650w/8ohms. I only use channel A on my amplifier, so i nees 4 ohms to channel A. e: Is that ok? I just want good sound, soundpressure level doesn't matter, 100db is enough for me. On the attachment is my old subwoofer parameters. re 3,656 and bl 22 on my installation.
