Compact Dayton Titanic 15" Offset Horn Design

[vnwhite]

I've been playing with Hornresp modeling compact offset bass horns for HT use. Design parameters are a sub that goes to about 120dB from 20-150hz in as compact a space as possible - I have a 22" max width restriction. I'm planning on building two subs to be placed in the front room corners and external proamps plus MiniDSP equalization would be utilized.

After modeling several different 15" drivers, the Dayton 15" Titanic seems to produce the most dBs and the smoothest frequency response for very small enclosures. Attached is a Hornresp design I ended up with and a preliminary layout, which ended up being about 2.5'x2.5'x2'. I've designed and built several different types of speakers before, however, I've never built a bass horn. Do any of you experienced horn builders have any feedback or comments about the design?

Thanks,
Vince

O you ha e the build and cut sheet for your box? I have the same driver and want to build this box
Thanks

Not the same driver, it's a 400C; your Mk IV is overall a better 'fit' performance wise though. Download, IMPORT its file to view in Hornresp and for a lower tuned and somewhat larger cab, compare the TH I posted earlier.

Thanks I’ll have to do that and learn the program

You're welcome!

To just view, it's easy, click on Tools/Loudspeaker Wizard to view the Schematic, various performance [input] Windows, pop-ups; to use will probably require keeping the HELP files nearby, which can be converted to a WORD doc to print out and of course there's the massive Hornresp 'sticky' thread: Hornresp
