Hi Folks, im new to the list and this is the story so far. I`m in a six peice band and we have basically a Peavey system,but we blew the 350w subs and replaced the drivers with Eminence 15" Omega 800w transducers.Now,we tried a Adlib Audio system the other day and the bottom end response was amazing compared to our bins-basically,the sound from the speakers sounded like an extension of the bass drum,whereas our Hysis xt115 bins sound throttled which may mean the cabinet is too small!Has anybody got any plans for these units as i dont want to make a cabinet and find its wrong again!
Cheers |

If you're planning on going for basic reflex boxes (ie similar to the
XT115) then you probably can't go far wrong with a cabinet of 100-130L
tuned to 40-45 Hz. I've built a few 15" reflex subs and anywhere
in that ballpark seems to give useable results. You're never
going to get that low with a 15" sub without sacrificing efficiency and
power handling but flat to 45-50Hz is acheivable.
Download yourself a copy of WinISD (google it) and simulate your particular drivers. Once you've got a cabinet volume and tuning that works, it's a fairly simple matter to convert that into a design. Circular ports (drainpipe) are ok, but I prefer shelf ports (ones which are effectively a slot at the bottom of the cabinet). Hope this helps, I'm sure we can guide you towards something that will work. |

Hi,thanks for your reply,so do you think i would be better flogging everything off and going for an 18" sub. Ive heard people say that once you use an 18" you never go back to anything else! I could build a pair of X1`s but which drivers can i use for best results? |

What type of music do you play, what do you use for mid-tops and how
many of the 15" Omegas do you have? Some info on which amps
you use, crossover etc might also be useful.
There's nothing wrong with 15" subs, some people prefer them because they are often more punchy than 18"s. Also have the bonus of being smaller and lighter. One of the problems with the Peavey bass bins is their construction; might as well be cardboard. Build quality, especially choice of materials can make a big difference. X1's would be a big step up, especially in size and weight but could be an option. |

Those 15 inch Omegas might work in these cabs: http://www.fane-acoustics.com/public_html/media/pdf_media/Ca binets15inch125L.pdf

Yup, probably about right.
