While reflex are the definite choice for many gigs/venues, 4x decent scoops will cover 400-500 people with effortless sub.
Many such venues will only have 13A plugs, and may struggle to provide power for 8x 18s to do the same job, if bass heavy material is played. |

Yes thats what I thought, that it doesn't work like that. I guess the original question was if some of you would have opinions on the best way to produce sub bass with reflex design equivalent of spl produced by for example 4 super scoops with PD 1850's. To get the same pressure but reflex sound quality.
I guess this design is not available??? Could you tell a bit more, drivers, tuning freq, etc.? What is the difference in having double 18" box instead 2 x 18" boxes? I know this has been discussed here before but didn't really find an answer, just that its not a big difference.
This is a good and practical point. Many thanks for all your answers!

Lev, if you do gigs on 13A plugs then that is a pure amateur gigs then. I can not think of any venue here that does not have at least 3phase 32amp socket available. With 64A being a standard norm. So if the power is not a limiting thing, then surely there are double 18s that will go lower and louder then a super scoop loaded with a PD1850. Which i think was the original question.

Except Macedonia is not the UK, so what you have there is irrelevant... Have "personally" never been impressed by 1850 in Superscoop. V18 in Superscoop, or 1850 in ASS scoop, different ball game. There are plenty of venues in UK, that hold 1k+ people, and only 13A mains plugs are available, unless people attempt to tail into "kitchen" supplies. That's why to many here, "efficiency" is key.

What kind of music do you want to play? Scoops have a unique scoopy sound (colouration) to them when they're holding long bass notes which some people like. |

IMHO, No point comparing Scoops to reflex cabs, people have personal choices and preferences. Mates like to use reflex for live gigs, and Scoops for 400+ people Reggae gigs. Edited by levyte357- - 13 May 2014 at 11:53pm |

There is no need for this design to be available as it's only a Reflex cab, although I suppose that if you don't have the wherewithal to tune, then it might be difficult. From memory, I believe the low end was in the high 20's at -3db, the speakers are B and C 18TBX100's, The cab was around 380L. 1w1m would have been around 100db. What you have to remember is that a cab that goes lower than a scoop will go further than you might calculate. Just think how, at a distance, you will always hear the lowest frequencies over the higher ones. It's just down to the longer wavelengths being produced. I think from experience, that 2 speakers in a non separated box sound better. Others might disagree, but I think there is always an advantage with common damping that two speakers provide when working in the same cab. I would never do this in a mid cab due to the possibility of standing waves, which is what you don't get in a Low Frequency cab.

Lev, that venue has to have a main fuse box where you can connect your power cable directly to the main rods bypassing any in house fuse and use your own power distro with fuses.
But that is how pro people do the stuff. You wouldn't know any of that. Using only two 13Amp sockets is seriously limiting the real capability of your system. That is 26 amps total. Meaning less then 6KW for the entire system. That is about what i push in one of my subs :-)
