hi !

im planning to use

1 MT122 (2x B&C 12NDL76, 1x beyma CP800TI)

with

4x HD15 (PD 154) 2x2 on top of each other, curves open to the sides,

together as a monostack on a 4 day outdoorevent.

routing via ultradrive, amps crown /qsc.

since the HD15s specs say, that they go as low as 52HZ

im thinking about, if it could lack some bass.

music played: EDM, psy, dnb, reggae, metal, pop, rock

volumes 70% conversationlevel, 30% pedal to the metal.

what do you think? will there be enough satisfying bass or

should we add a hogscoop and use only 2 HD15?

i read, that if hornmouth are combined from several horns together,

they could play a little deeper than a single horn.

thx !

i have 4 hogs /1851, more brutal with 4x18 is hard.

but hogs are heavy so we pick 4x HD15. even though that was not my question.

HD15s on sub, will never be fine for Reggae, DnB.

Even as a Mid bass cab, compared to others, HD15 is not impressive..

Freq resp of HD15.

Good luck trying to get enough sub out of that, to play DnB/Reggae, to discerning listeners, outside.

Also, Beyma CP800TI is a dreadful sounding comp, above 10khz, Beyma CP750TI is much better, and great outside, even on budget, large format horn, like Paudio PH-4525.

 

Playing outside is completely different to playing in small venue, mediocre system will embarrass you and your crew, and blown drivers, due to pushing system beyond it's limits will cause further loss of reputation.

If you don't have the budget to build system suitable for purpose, maybe better you hire in 3x 1850 Horns and  3x MT121s.

Will have to run the 1850 horns upto 160hz, but will still sound better than HD15s.

1mansoundsystem, you need to provide a bit more information. How big is the crowd, etc.

To go with your Hogs, build 4x ES18s, and 4x MT121s.

As long has all cabs powered suitably, with decent LMS setup, Industrial strength outside system, right there.

I have a video somewhere, of 4x Scoops, with 4x Boke kick cabs, and 4x MT121 tops outside.

Unintentionally, that 1x stack, drew a crowd of around 1200 people outside, and had them dancing past midnight.

damn......

crowd is 9 people. this is a paintballevent and we play for ourselves at campground,

maybe growing some people in the night. no crowd, no audience etc.

this the first time i can play the HD15 outside, so thats why i chose them over a 2.1 pa.

and bcuz i love horns.

i could add a hog or more HD15 but that wont make sense, bcuz our transporter has to carry a shitload of pb-equipment for 3 people and people want to chat in the evenings or in between. so just a slightly bigger festival-rack at the campground.

my question was all about, if the 4x HD15 can bring up a reasonable amount of bass or if it sounds

weird bcuz of a lack of subbass. now i got a first impressions and thats cool.

CP800TI vs 750TI: the 800 doesnt look too good over 10 khz, yep.

im not on a budget, would you recommend exchanging them for 750s, or hitting it with the EQ at ~15khz and ~17khz ?

i got 4 MT122s so that means exchange 4 CPs.

which kickbins would be better for that purpose of solely kickbass? my descision to build these was

bcuz i listened to them live and was blown away by that combo (4 hogs and 4 HD15, couldnt get to know which drivers they have been loaded with)

2x Hogs, 2x HD15s, 1x MT122 would be great.

For the future, 2x MT121s, sound better than 1x MT122, and easier to transport/stack.

Also, you are far more likely to get away with a stack of 4x ES18s on sub down to 50hz, as opposed to HD15s.

But be aware, strong subby drivers for use in ES18, will not do anything nice over 150hz.

very unlikely that i dispose of the MT122s bcuz they have been an insane amount of work, ...and.. you know.... but i will keep your recommendation in mind. and yes, the MT122 are a pain in the ass to transport.~75kg a piece.

-------- a little OT:

our campingground will be ~20x20m 7-8 tents, 4 cars.

last year we had 2.2pa. 2x 12" thomann the box active, and 2x active subs fun generation

(15" 179eur/1pcs). the worst crap there is. i tried to keep them from spending so much money for this junk.... he bought 6 of these subs and is now is in the process to see, that i was right by telling him: save up, buy decent 2.2PA, and to regret but wont admit it, of course, now that he sees, that more and more of his subs causing issues. you know how things go......

the tops were bought used, age and usage unknown, and got a damaged gain-potis both the same night. one sub started to razzle n scratch at certain volume, the laptop couldnt be hooked up to the pioneer-mixer, our dj lost control, and he took one year, to appoint the failure to the software that suddenly wont work together with the mixer anymore. he said. 

thats why i will do the sound this year, my planning, my equipment, and im pretty confidend, we wont have those kind of issues again. i will report back about my impressions on the performance of the setup

You will blow CP750TI, trying to get plenty 15-7khz out of them

If budget not an issue,  look at Beyma CP750Nd, with flattening eq between 8-14khz, will be solid upto 16khz, especially in multiples.

thats true, haha. but since transporter space is limited, the 4 hd 15 + 1 mt122 iss all we can fit into it with all the other stuff like pavillon, tents + peripherals, beercrates, fridge, chairs, pb-equip etc.

yeah, 1 hog would kick ass, but since this is not even a music-festival, late-night activities are limited to

some drunkards singing karaoke and vomit in the bushes. 1 hog in addition would be only considered, if feedback here would have shown that hd15 are in no way capable of any bass at all. we had them playing inside a few times, and they blew out some serious sound together with hogs. but as some said, outside is a totally different thing.

levyte357: i was talking about equalizing that weird range from 15khz-17khz of the beyma cp800ti

i really dont wanna blow any of my beloved speakers - they too expensive :/

Yes - sometimes the recommendations here are a bit OTT and more directed at large parties & Big Bottom Nutters!

And down here, some of the systems you see at the attractions at the fiestas can be ridiculous - also OTT overkill.

Which is why I loved these:-

More than adequate for the job they needed to do. 

+1   

Mono stacked two wide two high will do. I did it many times, outdoor, no problems. 

70-80% of the music you will not be missing anything

not sure about that... my 4 HD15's didn't do so much with a pair of 218s

that could be because they had fane sovs in them

or they were being measured agains 2 218s

hmm

i finally had to rearrange the setup to 1 hog, 2 hd15 and 1 MT122.

not bcuz erratic brain, but some dudes requested the hog, they could

remember this foe from 2y back when we had our partyroom and did some 12cm concretewall

cracking with 2 hogs 4 hd15 and some other wildly assembled stuff at full volume.

so they voted for having a hog at the location. at least the question if there is enough bass is gone now. if you interested, i make some videos when all is up and go. i do some funky lighting stuff too, bcuz building cabs and doing lighting/laser/uv-deco are my hobbies 

and if you want to join us, we at poland, brozek, scenario big game paintball event, if by any circumstances u be there, come over and have a drink with us (u hear/see us)
