I am converting my garage into a media room about 4500ft^3. I have Two old Shiva EBS subs. Should I build an IB sub or stay with the Shivas or use both? How would I use both? I have a Marantz AV7005 processor with one sub out and Audyssey MultEQ XT My Shivas look good so I don't want to kill them off unless they are not helping.  |

I would use both. I have 8 x 15" subs built into a wall behind my screen as an IB, and I have 4 x 12" Shivas as nearfield subs directly behind my front row. The Shivas add a bit more tactile feel. I had to turn them way down because I still want the bass to sound like it is coming from in front of me, but they add to the overall punch. I use a miniDSP to balance and EQ the subs.

How large is your room? So if I was to use both I could buy a MiniDSP and put that between my processor and sub amps? I was hoping two 18" subs in an IB would be sufficient. You are making me feel insecure! |

Hi
Sorry for the delay in responding my browser didn't update showing your thread...
In this day and age most wouldn't consider a pair of 12" subs adequate for a dedicated HT.
Depending on the size of the mains, one possibility would be to use the Shivas as midbass modules
I think a pair of 18"s would be fine for a converted garage

Yes at the current pricing I don't know a better value than the Fi 18"s

You are making me feel insecure! My home theater takes up half my 22' x 32' basement, but there are no hard partitions. My brother was over a couple of weeks ago and we watched Ford v Ferrari. There is a scene where a plane flies low overhead, and you could feel the vibration sweep through the room. With a cement floor, it takes a lot to feel the bass. |

Would my Adcom 555II amp be sufficient to power a twin Fi IB3 IB? If not, what is the popular value option currently among DIYers?
What Ohm option would I choose when ordering (Single 2 or Single 4)?

Sure a 555 will drive the IB
Get a pair of 4ohm drivers

Thanks, I ordered two just now. I was thinking of building it similar to onesquin, ibsubwoofers.proboards.com/thread/1553Any suggestions about where to put it in my attic? Here are some pics of my converted garage. |

Yes that's a good thread to follow
I think you should do a floor crawl with the manifold to compare various places before moving the manifold to the ceiling. That's because the alcove will likely create a big bass null

That's because the alcove will likely create a big bass null I do not know what you mean by "floor crawl". I would guess that means building the manifold, attaching woofers, hooking up to system and running sweeps in different places to find the flattest response? |
