Looks nice!

Thanks BP1Fanatic,

I saw also some of your DIY build subwoofer photos and they looks nice and I am shure that they play nice too

 

[BP1Fanatic]

Thanks guy!

Wow! Zivko, are you really using 5 of those 150l horns for your front 3 channels in that small room? You are admirably crazy! Can't imagine you ever turn the volume knob up very far.

Hi jwmbro,

yes knob goes not up very far, high sensitivity, less power, more SPL and energy saving, I can see up to 1-2W at LP which is 4m away, room is not so small 5,5m x 5,5m x 2,7m but speakers are big, I have two more FLH in right back corner

Omg, wicked hts!

That video I want to see, I am sure it's an earth shaker!

Hi djlivex,

wondering if there are any less expensive alternatives to the proposed woofer, any suggestions?

Yes there are or 15-inch or 18-inch less expensive alternatives, a lot of woofers are OK for this design, if you have less expensive woofer with its datas I will put the datas in Hornresp to see the outcome.

Hi henko,

sorry this one is not good for this TH design

 

[ZivkoF]

Thanks epa, it was also your contribution to the realization of this project

Very nice!!! One day I will build a nice HT sub like that. Any plans for those tops??? Hey Djlivex, did you finish your Tuba 24's? I see you are in Tampa, I am in Largo and I have always been curious about the BFM cabs.
