I can source the SEOS 24 locally for 270 dollars in glassfiber and with another 10% I can add a color and some sort of marble finish.
The BMS will set me back 600 dollars.
I am considering the AE TD15M woofer and maybe an Audiotechnology 15" flex unit, which I can get 10mins from there I live. I'm visiting the audiotechnology factory in the near future to have a talk with them about what driver could work with a 500hz or so XO.
Initially I would try and make an XO using a minidsp.
I'm starting off bulding a center channel, and if it works out I'll put effort into left and right channels. The center is hidden so the cabinet doesn't have to be pretty, just well build.
I am a total noob designing XO's, so I am jumping into this.
