I was under the impression that the variable input voltage thing was a doing of the SMPS itself, not PFC. Are you sure these amps have PFC?

I got an email from them announcing the D-3004 with 4x8600W@2Ohm but in the follow up mail their rep said that the amp isn't really 2Ohm stable lol. But if it really performs up to spec, you could run 3 Skrams per channel for a total of 12 cabs off of a 1U amp, which would be pretty sick. But of course pushing the amp pretty hard.

Nice endfire setup! I'm in the process of building a 4th sub (not Skram but also 21") and will bring all 4 to a wedding next month. I also got a mail from CVR that they released a new 35KW 1U amp. Would love to test it but can't really justify buying stuff just for fun yet lol!

on a 16A 230V i run a crest pro9200 2 Ω Stereo 3,250 W through massive wires and get a tight sound out of eight 8 Ω lavoce 21" drivers in the skrams that will surely be too loud for any wedding application the setup works without breaking the circuit, sounds great and is loud enough for my applications. with the limiters set to avoid amp clipping i have no risk of burning the drivers or overextension. on the wishlist i would say a powersoft x8 would be the optimal amp&dsp for 8 skrams giving total flexibility in setups and cranking the max output.

Ah, I have read about this amp already. 4 x 5000watt 4 ohms. I cant buy anything as of yet but looked at buying possibly the CVR or FP amps for sub power. Would be powering only four Skrams once they actually get built.

Hey since you mentioned Michael Curtis, i just watched his videos and

I did the inline inverted  cardioid setup and indeed! works like a charm !!

i used only 2 subs but the rear rejection was unbelievable

 

my settings was what he used

68Hz max summation freq, rear sub offset 4.15 ft (50" ) , rear sub delay 3.67ms

since i have passive subs i used an old BSS delay processor i bought for peanuts like 4 years ago  to delay my rear sub

cause the drive rack cant delay the LOW out individually CH1 or CH2, it works like a charm !!! now i need more subs and more amps!! 

i want to build some SKRAMS!!!

Hi Again, I have my 4 Skrams coupled together laying on there sides. Supposedly I get a 6db gain having the subs coupled the way I do.

BC21SW152 4 ohm drivers

I am using 2 QSC PL380 amps in Stereo

My generator is a gov surplus Onan Quiet Diesel HDKAV 6000 watt. I am starting to max this genny out, and when I add my lasers I have to put them on a differnet generator. 

I do not use any Dampening because I don't want the Playa dust having a media to cling to inside. 

I am Running Meyer UPQ tops with a 15" drive and 4" horn for my Mains, and Meyer UPJ's with 10" drive and 2" horn for my Fills. 

This System is OFF THE HOOK!!!!

Thanks again Josh, This years Burning Man was fantastic because of your design!!!! Edna is starting to get a big following of BASS HEADS!! YOUR DESIGN KICKS ASS!!! THANK YOU!!!
