Hi,
I'm about to embark on a DIY Sub, my first, and just wanted some re-assurance that I'm on the right path.... Initially I was considering more esoteric ideas, such as ELF / Linkwitz transforms etc. but have now decided that I should learn to walk before trying to run. I'm pretty much sold on the Adire audio low Q ( 0.577 ) Sealed Tempest design. It's big, but I can live with that, I already have a butt-ugly rear projection TV and a meter high flexy-rack with all my equipment on it.
My room is approx ( 4.5 x 3 x 2.2m LxWxH ) and the sub will be powered by it's own 300W MOSFET amp. The rest of the system is a Denon AVC-A1D ( 5700 in the U.S ), Epos ES22 floorstanders at the front and B&W DM601s as rears. I'd like the sub to perform well for music as well as movies and I'm hoping this'll do both. The Epos speakers go down to about 40Hz and are pretty 'tight'. I don't want the sub to muddy their sound - hence selecting the sealed design.
Has anybody had any experience building this design? Also is it a good way to start? If it works out then I wouldn't be surprised if I had a crack a different design in the future but I want to start of with something acheivable.
I have played with LSPCad and have realised how important positioning/room size etc. is on the frequency response, although I'm hoping that a sealed design will be less tempramental than a ported one for a beginner.
Any advice would be appreciated
Thanks
Simon
