Sealed box for IXL-18 - Page 2

post #31 of 40
Resurrecting this thread again. Got my 2 IXL-18 Mk2 drives this week. Planning to put them in two 4cuft sealed sub enclosures from DIY sound group. Would two Dayton SA-1000 rack mount amps be enough to power each of them in a 2600 cuft room? Seems like the amp has a defeatable subsonic filter & bass boost which is perfect to boost low end in a sealed cab. Also looking at Crown XLS series amps to power these. The amps will be in the theater room therefore looking for amps that are quiet.

What frequencies does the Dayton amp boost? If you are going sealed, I would think that using a HPF would be unnecessary. For the price of the Dayton amp you could purchase a new EP4000 or an iNuke3000dsp, either of which would likely be better.

I am looking for something quiet as the amps will be located in the theater room. I believe Dayton applies boost around 25hz. The subsonic filter is defeatable on Dayton so that works out well. Not sure how the SA1000 amp tested in bench tests.

There are lots of quite amps out there. I have personally owned both the Behringer EP4000 and the Behringer iNuke3000. The iNuke is a pretty quite amp, and with a fan mod, it becomes even more quieter. The EP4000 is pretty loud, but a fan mod will help significantly. If it were me, I would go with the iNuke3000dsp. That would offer up some nice power reserves, be pretty much silent, and also give you the ability to use its on-board dsp for boosting, assuming you build a sealed sub.

Thanks Marty. I think I might go with iNuke3000dsp & just do the fan mod if necessary.

Ready to pull the trigger on iNuke3000 amp to power two IXL18 MK2 subs in two 4cuft boxes. It outs out a little over 800 watts per channel at 4 ohms. Is this an RMS rating or peak rating. Just wanted to be sure as the IXL drivers are rated to take 800 watts RMS & wondering if I should step up to iNuke6000 but then again its not rated for 2 ohm operation & it will take one more fan to replace.

Are these IXL-18 mkii subs a duel or single voice coil design? Are you planning to wire them to present an amp load of 4 ohms, or 2 ohms? If it were me, and I had duel IXL-18 mkii subs, I would most definitely step up to the iNuke6000dsp, also assuming that you wire them for a 4 ohm load at the amp.

I am not certain that the iNuke3000dsp can push two of those IXL-18's to their maximum potential, although I have not modeled it, just going off what I have heard/read about the IXL.

What made you want the IXL-18 mkii over something like the UXL-18?

Hi Marty, these subs are single voice coil & present 4 ohm load. Went with IXL due to price. To my understanding the main difference between IXL & UXL is mainly the cone material & higher xmax. Other than that the basic voice coil/motor appear to be the same.

Will the IXL offer better performance than the Dayton HO18 or SI18? I looked at both the IXL-18 and the UXL-18 before deciding to purchase my HO18's, and if it were not for the price, I would have gone with the UXL-18. Sucks that my PC has a shot hard drive as I have been having to use my iPhone 5, which can't do winIsd, to my knowledge. I wonder how the IXL models compared to the cheaper Dayton and SI 18's.

They changed the design of IXL18 mk2 this year. Compared to previous model it has bigger 3" voice coil & a different motor design more akin to UXL18. I already have SI HT18-D4 therefore figured I try something different. My main use is for movies.
