Re: Dayton IB385-8 15" sound quality?

4 pages. 1 response ,the very last, attempted to answer threads initial question. and this cat apologized. sound detail replaced with spl. if phase coherency is maintained, 4 independent drivers may decouple room modes more effectively, at least when using conventional box subs. stress to ceiling structure spread out and future driver repair cost and complexity potentially lessened. lighter weight per unit safer at potentially dangerous installation height, factors such as these could easily out weigh a few db at threshold of hearing frequencies. very immature, gentlemen. very immature. it's like you folks enjoyed this. like you derived pleasure from helping this thread's poster hotrod his ceiling. BE CAREFUL. you might suddenly realize you are dangerously close to having fun.

Re: Dayton IB385-8 15" sound quality?

i had 4 of these four a period of time, and i loved em since they produced good sq and proper spl for the price i paid ~300 $. But unfortionetly i happened to play a bit to high with to low freq which ended in 4 non working drivers.
But if you keep playing at a decent level you should be happy

edit: didnt read the thread before i posted and i saw you've ordered already

I just ordered a pair of the Fi IB318's 4ohm (4ohm seemed to be the most versatile).
$550 delivered. They say it could be a 30 day built time.

Probably will end up going with the EP2000 amp.

Thank you all for the input.

The 2 ohm subs would be a good choice if you're sure 2 subs is all you'll need. Each would receive 650 watts per channel on the EP2000, or you can wire them together in series for a 4 ohm load, bridge the amp and get 1300 watts.

Re: Dayton IB385-8 15" sound quality?

Sorry for dragging this out but I sold a few things at the house today and came away with some extra cash. I can afford to buy a 2ohm capable amp now instead of having to wait and use my existing 4ohm/8ohm amp.
I have decided on the 2-Fi IB318's. But now that I can afford the new amp straight away....
... is there any reason to get the 2ohm instead of the 4ohm driver?
... if using 2-2ohm drivers, is the EP2000 amp still the most practical choice?


Here's my understanding of the 2ohm vs 4ohm difference:
Higher restistence (i.e. 4ohm/8ohm) delivers better sound quality.
Lower restistence (i.e. 1ohm/2ohm) delivers more power.
Exception...If you have an amp that is made to run optimally at 2ohms, then running a 2ohm load will yeild the best sound quality.

If all this is true, would the EP2000 amp deliver better sound quality with 2ohm drivers or 4ohm drivers?

Re: Dayton IB385-8 15" sound quality?

With 4 ohms subs, one to each channel, the EP2000 would be my choice. $259, shipping included.

Re: Dayton IB385-8 15" sound quality?

Good idea. I'll test drive it first before definitely saying that just the 2 drivers will be enough.
But I'm 99% sure that 2 drivers will be enough. As mentioned earlier, I just want proper bass. Even if this IB set up is only slightly better than my current set up, I will be satisfied. If I want to show off or make my head explode I can go out to the garage and listen to my car's HSU sub (it's a 12" sealed cylinder enclosure, not as loud or earth shaking as the JL dual 10" bandpass that I used to have, but the HSU still rattles the windows and has 100% better sound quality than the bandpass).

Re: Dayton IB385-8 15" sound quality?

It needs to be determined first if there's a possibility of adding another pair of subs in the future if you decide 2 subs aren't enough. If that is a possibility then an amp choice can be made with both senarios in mind, 2 subs now, 4 in total later.

I will definitely try this with my amp. But I don't want to be missing my 450w/ch for my front 3 speakers for very long, so I'll have to get another amp soon.
What models would you all recommend (keeping in mind I would be using the 4ohm drivers)? I've noticed that the Behringer's are very popular here and on that other IB website.
What's best: a very powerful 1ch amp, or a less powerful 2ch amp?
