First time ever, heard D&B Line array, on a Roots Reggae system, with the D&B Amp/controller "thingy"?

3x small cabs, kept up with 6x 21" Folded horns, getting the granny smacked out of them, by K20, with power direct from fuse box in Kitchen.

25M back from stack, SPL, clarity, sweetness..

Someone please explain..

When the 21s were turned up they wernt keeping up. And still lacking in lower midrange. But still sounded nice and clean none the less.

Could it be that 21 is a specific design so will play some notes well but may not be an all rounder. Also aren't 21's slower in their response. One more thing I suppose if you have a specific design the tuning got to be spot on. Wish I was there to hear it.

All through the night, Errol was changing the levels.

A bit before you got there, for about 45mins, all the levels were spot on.

Even when he pushed the 21s so hard, 25M  away, the floorboards under under your feet, were vibrating violently, and bass pressure was all over your trousers, coat... Shocked

Put 2150 in correctly designed cab, and power it with suitable amplifier, with suitable power supply, and it excels. Just like many drivers.

Many people, place driver in numpsy cab, driven by cheap amp, connected to cab by shoelace, on floppy mains supply, then say 2150 is crap.

D&B put a lot of effort into getting very high SPL out of small cabs and the processed amplifiers with feedback from the drivers allow them to keep it clean all the way to the limit.

However small line arrays always suffer from a lack of low mid authority.  To go from and 8" or 10" up to a 21" on sub is a big jump and likely to leave a hole.

At this "gig", there were kick/mid cabs.

To me, when levels were set right, mids very very present.

C7 top is unbelievable and it's old now, D&B are soo clever that 8 1x18's have covered 2000 people and the total watts in is less than a mobile wedding DJ :)

It's everything, not everythink!

That's Q1, quite old now but lots of bang for buck. 

3 cabs per side is not really working as a line array, but still makes a nice noise.

They're Q subs, although the word 'sub' doesn't apply that much.

Whats here to explain?
Its a proper engineered box. Not some DIY top box with all sort of compromises.
Everything is nicely time aligned and without cancellations.

Have to agree, did hear that.

Serves as a good reference, as what mid tops should sound like, even at high spl/distance.
