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.

tried out 8 skrams cardioid outside setup, cancelling in the back was incredible. also the beam was very narrow, perfect for the situation. walking in and out of a zone of massive bass adds to the overall experience of the guests as well. i followed the MichaelCurtisAudio instructions for this setup and they worked like a charm. crossover was a bit higher at 100Hz ato go a bit more relaxed on the tops, and the skrams punch in the higher bass as much as the kick in the lower. also i was wondering how it makes a difference to stack the subs with the openings closer to each other compared to what we did, when the wavelengths are so long. i didn't notice anything weird the way we stacked them. i even considered stacking the top ones upside down, to space the stack. wouldn't that improve the beam pattern even more? we had no time for measurements. the skrams produce a super dry bass, ludicrous levels achievable even with a lesser efficient cardioid setup like we did. my guess is you could have a 1000 people audience with 8 skrams. (these are IPAL ready, just imagine the output!) two skrams fit on a europallet, a skram is possible to stack with two guys, the height of two skrams is perfect to stack a top on... they fit through any standard door, the driver is savely protected and a splash of beer won't do any damage either. a very convenient design.

they are designed by a friend, inspired by the syntrip and of course synergy. the dcx464 driver makes a very low xover to the 12" woofers possible, what makes this specific design possible. its a 60x90 horn.

vent tuning lids added to the skrams. dsp settings are LR 24dB at 10Hz. bass is more exciting even at listening levels. fun times.

THANK YOU for sharing the skram! after making an initial two skrams, i`ve just finished another six. eight skrams in total, loaded with lavoce 214.50 1700W/8ohm http://www.loudspeakerdatabase.com/LaVoce/SAN214.50 i`m running two channels with four skram cabinets each at two ohms from a single crest pro9200, 8sqmm cables instead of breaking the woofers in freeair i had them broken in last weekend with a live analogue acid tekkno set and tekkno DJ. there was too much sub, so i rolled off at 40Hz which is typical for tekkno sound systems, and reduced my low shelve boosts i use for bassmusic and personal listening preference to 0dB, and everyone was happy with the bass tone. anyhow... in september i will have D&B and bass music, techno, schranz and an eighties events. these beasts will move alot of air! next step is making vent shutters, so i can flexibly tune the skrams, an initial test showed promising infrasonic results. the idea is to use a subharmonic syntheseizer so i can fiddle around a bit during the parties. plenty of headroom to tune to the infrasonic... also i will venture into outdoor cardioid setups now i have enough cabinets. i`m looking for volunteers to haul cabinets. if i ever have the chance to do outdoor measurements i will post those here as well. btw. the grey cabinets will still get a finishing paintjob
