As for amps with built in DSP, I'm not aware of any class AB/H big iron amps with it built in. I ended up getting the 10x10 miniDSP. I'm using it for all my subs and mains. The downside is the stupid phoenix terminals, which makes doing any quick changes on the fly impossible. I made this for my equipment rack to make all the connections a breeze: Unlike the cheaper models, this one can handle over 16v in and out before clipping. Really nice to not have to worry about that.

Mine had the 32a PowerCon, just a wimpy 14g cable connected to it. It was purchased through Seaton. As far as I can tell, the sp2-12k is only available in 240v.

Looking forward to it. There was one thing disappointing with the sp2-12k...the pathetic power cable it came with (14awg)! I bought this from amazon to replace it: http://www.amazon.com/Tripp-Lite-Heavy-Duty-Extension-P041-008/dp/B005KKCJRW

Oh BTW, here's some testing I did between the CC4000, CC5500, Pro Lite 7.5, and the SP2-12k on my pair of Ghorns at 15hz. 15hz is near the excursion minimum so there was no risk of bottoming the drivers. All amps were on dedicated circuits. Crest Pro Lite 7.5 (120v, running in stereo): 15hz: Clipping at 127db (power cycles when attempting 128db) SpeakerPower SP2-12k (240v, running in stereo): 15hz: Clipping at 130db (2) Crest CC4000 (120v, one bridged per Ghorn): 15hz: Clipping at 131.6db (2) Crest CC5500 (120v, one bridged per Ghorn): 15hz: Clipping at 132.8db Very pedestrian testing but proved to me that all these amps in question appear to perform up to specs.

Time to revive this thread. For the past year or so I've used the Crest CC series of amps and really like them. I've been powering my subs and mains with them and can't find any fault with them other than they're heavy and the fans aren't completely silent. I also recently purchased my first SpeakerPower amp. The rack-mount SP2-12000 has fans but they only turn on if the amp starts to heat up, and that's been really hard to do. I had to push the amp to clipping on music for over 10 minutes to get them to turn on, and even then the RPM was really low and I could barely hear them. For a single amp running 2ohm stereo this is a hard amp to beat.

Awesome! I'm looking forward to the test results and hope it performs as close the simulation as your other horns.

With the filters I have on them it's nearly impossible, but, you never know.

Yeah, that seems to be the story with most Fi drivers. Inductance monsters but durable.

The Fi Team 18 looks like it's gone through a few modifications since the last time I saw it. Different cone, bigger surround, and a different motor with fewer slugs but they're larger in diameter. Similar xmax as the UXL, but possibly with more motor and increased thermal limits with the dual 4" coils. Call me crazy, but I stay on the lookout for a possible LMS 5400 replacement for the Ghorns in case I ever blow mine up. HST-18 and Zv4 are a no go, and finding the UXL in stock is iffy.

I sold an amp for a buddy a few months ago on eBay, and it had been YEARS since I had sold anything there. To my shock and surprise, the eBay fee was 10% of the selling price!!!!!!!! I really wish I had the cash for the amps man, I'd love to have them. Even if I sold four of my Crest CC amps I couldn't cover the cost of one of the K10s...

Unfortunately, all I saved was the pictures. I don't have the files I could load into REW anymore,

I wasn't in pure direct mode, and I was measuring from the subwoofer outputs. My soundcard is a Behringer UCA-202, and I created calibration files for it so the response was perfectly flat before adding the AV7005 or the MiniDSP into the signal chain. Do ours really measure that differently?

MiniDSP balanced 2x4 Marantz AV7005 (Red line is XLR, green in RCA)

Here's what mine looks like with nothing playing: How/where do I import the calibration settings for my UMIK?

I found a file named "Bossobass Custom Settings.zip" from May of 2013. If that's not it please let me know.

Where can I download one of your settings files so I can mimic your view?

Are you going to build a ~10-15cu.ft sealed box for that massive 24?

Dang, I was guessing that driver WAS the 15"...but it's an 18"?!? Dang man...

Funny enough, this post was just made on AVS by N8DOGG: "Since I've got both the 7500 and the 14 clone, i'll give my 2 cents. If your running 2 ohms, get the peavy, anything else, get the clone. My 2 new fp14's work great, no issues so far. They do a better job than the peavy with my FTW's, they hit harder than the peavy does but I have 4 ohm drivers. The subs just seem to really hammer with the clones and hooking up the peavy, it's not the same experience. I don't have any charts or numbers, just going from feel."

When first powered on, the fans stay completely off for a few minutes. Then, even without playing anything, they'll turn on at a pretty low speed. At this point they're still more quiet than say a stock ep4000 or inuke by far. I've hammered on them pretty good for a few hours and the fans have barely speed up, but it's not something you'd want in the same room. Since they have the 30a twist locks, I had to upgrade the outlets, but each amp has a dedicated 30a circuit. For SQ, I can't tell any difference from my fp14k's. They hit just as hard, sound just as clean, and running some sweeps in REW show they have the exact same response curve down to 10hz. My horns can't play much below that, so I can't test any lower. As a power test, I had one Othorn on one channel of a fp14k clone running in stereo. I played a heavy bass track until the clips lights were on hard. Using my calibrated UMM-6 and REW as the SPL meter, I took note of the max SPL. I then put a bridged Crest in and matched the SPL. There was no hint of the clip lights, and the fan speed didn't increase. Yes, an unfair test, but I wanted more power and definitely got it.

I got some open box CC5500's off ebay for $799 from an authorized dealer. Mint. I have each of them bridged powering an Othorn. HOLY COW!
