Hello Everyone!
First I would like to apologize if this is a duplicate post. I did some searches and found similar topics but not this exact question.
I currently have a single Ultimax 15 in a 3 cu ft sealed enclosure. I have already purchased a second and am planning to run two 15s each in one enclosure with two separate chambers (space is an issue for two completely stand alone enclosures). Long story short, I purchased a Chane 3600 to push both the subs based off the reviews and the awesome responses from Stads77. Everything I was told about the amp was spot on. It is a beast and it sounds fantastic!
The problem though is the physical size of the amplifier, specifically the depth of it. I knew it would be an extremely tight fit in my cabinet but what I didn’t take into account was the additional depth of the xlr connectors. When these are added it becomes impossible to fit in my cabinet. I had considered modifying the cabinet but it is a home made cabinet my Father in Law and I built with natural edging etc. I just cannot bring myself to hack it up to make an amp fit.
So, finally to the question... what amplifier(s) that you have experience with would you suggest? Because of my depth constraint (18” comfortably) including cable connections I was thinking of going with a pro amp. Right now I am seriously considering either the Crown XLS2502 or the new Behringer NX6000D. I can see pros and cons for each amplifier:
-Crown
Pros: more reliable (I have head), more realistic output numbers, near silent, easier connections to home theater equipment
Cons: more expensive, less capable DSP
- Behringer
Pros: better DSP, less expensive
Cons: fan noise, adapters needed for hook up, possibly inflated output capabilities?
If you can provide any insight as to what would be the better option I would really appreciate it. Or if you can point out or correct my perceived pros/cons that would be helpful too. Or if you can suggest any I’m not currently considering that would also be appreciated.
Thanks in advance!
James

I used the Behringer amp... tested everything- worked flawless, ex a hum which I got rid of by grounding the receiver. While testing the fan was a bit loud and I decided to do the fan mod- super easy and took 15min while drinking a beer.. never would have heard the noise in my rack but decided to have at it anyway. I can send over pics later on .. |

I have never had good luck with anything made by Behringer, YMMV.

I'm using a pair of Crown 2502 amps for my UM18s. Dead silent, always cool to the touch, plenty of power.

Are your UM18s in sealed or vented enclosures? Do you feel one 2502 would be sufficient for two UM15s? The Dayton SA1000 was a good amplifier but it was definitely the weak link in the chain when I was using it to power the single UM15. it was kind of funny, I went to the local Guitar store and talked with someone asking if they had any Crown amps and he asked what I was going to use it for... He looked at me like I was crazy when I said HT subwoofer. Thanks Everyone, James |

Purchased my iNuke6000DSP from the local guitar shop, he thought it was awesome haha, the new Behringer line looks a lot nicer than my iNuke, mine is hidden anyhow but it has been rock solid for me. I have a limiter set on mine to about 1100watts, it has been bench tested at just over 2000 watts a side.

There isn't much of a DSP on the XLS series other than it controls crossover points, bridge mode, etc. You'll need a miniDSP or similar device if you're looking for a ton of DSP controls. I ran my dual sealed UM18s with a single 2502 for a while and at 775w it was plenty... with dual 2502s they truly presurize the room. I went with Crown as I didn't want to open an iNuke to swap the fans and I didn't care for their styling and all of those orange LEDs. I placed electrical tape over the blue LEDs on the Crown as they blink while in "sleep" mode. Here's a thread on a turn on / off relay I'm using for my Crowns: emotivalounge.proboards.com/thread/47057/trigger-cable-crown-drivecore-amps |

Haha I have to agree, if they didn’t have the new Behringer look they wouldn’t even be in the running because all my equipment is very visible. |

Or are you able to obtain low enough frequencies without one? I am still probably leaning towards the Crown because I am also not wanting to open up a brand new amp and void any warranty to install quieter fans. Thanks for the link to the turn on relay thread too. |

I use Nukes on my subs. My 3000dsp turns on and off via a swithced outlet. My 6000dsp has a trigger built in from Kevin and Bill over at GSG audio, Works AWESOME. Plug and play, I'm sure they could hook you up. I got mine a couple years back when GSG audio was still just an "idea".. They also made me up some cnc cut aluminum discs and plastic 3d printed "caps" to block the orange rings on my amps. Bill is super cool and is up to almost any challenge.
As Chad mentioned the nukes have been tested and while the specs are inflated they do burst pretty well (for what you pay) which is what you want for home theater and sustained power is still 1.5kw@4ohms iirc of course.
I had a 6000dsp die on me last spring, it would send a very low and loud rapid-fire tone through my subs intermittently. Luckily uxl's are next to bulletproof. Personally, I'm looking to move back to some sanway clone amps.. Or just bite the bullet and invest in speakerpower.

Do you have any experience with Crown amplifiers used for HT subwoofers? I have owned and known of multiple Behringer amps and EQs that have died for no good reason. They are just pretty cheaply made. Crown is much more reliable, as are pro brands like Crest and QSC. |

I appreciate your input. I haven’t completely decided but I’m really starting to lean heavily in favor of Crown. It just seems it will be easier to hook up, and seems that more people than not prefer it to Behringer. |

Thanks for the link to the turn on relay thread too. Sorry for the delayed reply, was out of town for a few days. Currently have the Crowns conected to the two sub outs from my XMC-1. The plan is to play with DSP after my dedicated HT is built within our new home... if all goes acording to plan, the room will be completed July / August. |

Hey LuisV, No need to apologize at all, you fine folks are all helping me and it is greatly appreciated. I have to admit I am jealous! We moved last February and I was determined to purchase a house with enough space for a dedicated HT.... Then reality set in and I we are in a house that isn’t really even suitable for Atmos let alone a dedicated HT room. Ive posted here looking for a XLS2502 or a Behringer NX6000D but no luck yet. I found a pretty decent deal on a Crown I may just have to snap up. Almost bought it this AM but couldn’t pull the trigger. James |

Ok, thanks everyone! So after replying to LuisV I just decided to pursue the deal I found on eBay. I will let you know when it comes in and how it performs.

Hello Everyone,
The Crown was delivered yesterday and I was able to get it hooked up today. Out of the box I was very impressed with it cosmetically. I was shocked at how light it is compared to any other amplifier I have ever used.
I am hoping that I can continue with questions on this thread, if not please let me know and I will start a new thread. I am having trouble with the settings on the amplifier. I currently have it hooked up to my Marantz SR5011 via RCA to XLR cables. I have the amplifier set to stereo with each channel to one UM15. I have the input set to .75 and each channel is also set with a LPF at 80hz. Immediately after hooking the amp up I could see and hear it was powering the subs but it was highly underwhelming. So I then did a calibration with the amp set as described above and the gain at 50%. During the calibration, and in comparison to the other channels the subs gave out little sound. So much so that after the calibration I checked the levels and it showed the subs were sitting 8’ further than the LCR when in reality it’s the same distance.
I then set the amplifier gain for each channel up to 75% which obviously improved the power output but the amp continually showed clipping. I scaled that back and adjusted the sub level on the marantz and again it improved output but would show clipping during any bass heavy scene. At that point I switched the input to 1.5 and the output was cut in half.
This is as you know my first time playing with a pro amp, let alone playing with a pro amp for HT so I am guessing I am doing something wrong. I simply cannot believe that this amplifier would be so easily shown up by my old Dayton SA1000.
Any thoughts or input would be greatly appreciated!
James

Crown amps are solid. Made to drive difficult loads 24/7. I have been around Crown for a long time. They just go and go. Home Theater, venue sound reinforcement, they just work. Behringer quality is suspect. Always about a lower price first over outright dependability. If I had a choice? Crown hands down. I have a friend running 6 of them in his Home Theater and they are great! Spend a little more and be happy.
Rule one! Buy it nice. Not twice!
