The labhorn is the answer 30-100hz

lab info


Horns are the hardest to design and build but have the most potential if not compromised to a harmful extent

I really want to build a (or 2) labhorns some day (or better, buy a basstech 7), but from the dimensions those things are huge at 4 foot x 4 foot x almost 2 ft! even if they do perform well, i'd check the dimensions of whatever transport vehicle you'd be using to make sure it would fit.

Lab horns would be awsome if I can design them around my cheeper EVM-15B speakers. I like the design more than the Jumbo 2-15.

But anyhow I can't build any horns till I get my venue. I might stick my speakers in small ported enclosures if I need them to gig with. They will still be quite loud enough, especially anywere I have to play a gig at college.

I think I'm just going to go with the cheep CTS horn tweeters. I need to save money to get the bigger amps that I will need to make it sound nice. I also need to buy a good mixer to start with. Since it's a coffee house type of think, I really don't know how many effects I want to pack into my rack. It really matter if I have a seperate monitor board and someone to run it. If I don't then I have to use all the aux outs for monitor outs, instead of effect loops.

Default A few hints....

.. I do this sort of small pub, jazz, coffee lounge stuff all the time, like 3-4 gigs a week....

...I don't do the loud young psuedo rockers..;-))

I have 3 sets of speakers which I use depending on venue and type of music. They all use Eminence drivers, and Motorola piezo horns but with a proper x-o on both parts.

It really depends on your purpose , do you want to be able to do loud dance type DJ music, or real music ?? Do you need big sub bins, how much power, etc, etc

What ever you decide.....

make sure you have headroom...

and get someone regular to control the system and be RESPONSIBLE for sound quality and equipment etc even if you have to pay them.. its worth it save your investment in equipment

DO NOT let young know-it-all would-be mixing guys touch your rig !!!!!! EVER !!!!!

Have you chosen your mixing console already? Any decent mixer will have one or more pre-fader, pre-EQ aux busses for monitor use, and post-fader, post-EQ aux busses for effects use. Some consoles have multiple aux busses that are switchable - pre-fader and pre-EQ or post-fader and post-EQ.

Take Andy's advice to heart. I've been there too - house engineer in a couple of electric blues / R&B clubs. Had the pleasure of working with James Cotton, Buddy Guy, Gatemouth Brown, half of the Fabulous Thunderbirds, and many other cool artists. Headroom is key!

I haven't picked a mixer yet. I might pick up something temporary for cheep if my band gets off the ground. For the venue I'm going to need to have at least 3 monitor mixes. The most auxilary and monitor outs i've seem on boards i think is 6, on the mega expensive ones.

I'll hopefully be getting my last two evm-15b's soon. Then I'll have to start finding midranges for good prices, and decide on a tweeter. The tweeter is going to be the hardest choice. I hope evm12l's arn't going to give me a humpy midrange sound. If they do, i can either eq them or build something into the cross over if i don't tri-amp.

I have a pair of speakers each having 2 Selenium 10PW3's and 1 selenium D205TI. They are powered by a Crown CE1000. For the low end I use 2 audiobahn 18"subs powered by a CE2000.
They sound great for their purpose.

The EV EVM 15 B is perfect for horn loaded subs. However,
due to there Very Low Xmax, I would look for something
else.

Currently I use EVM 15B's (200 watters) in a straight horn
playing low midrange. (1Khz - 80Hz) Each driver getting
825 watts continuous, with no fires yet (Anyone familiar
with EV's know they are prone to going up in flames before
they die)

Just for the record, the 400 watt Prolines are 400 watt
thermal. The 200, and, 400 watt use/ have the same
xmax.

I kind of got to this thread late. However, if you have any
questions regarding the EVM 15 - 18 inch Series, let me
know.

Just one more thing.............. The EVM Series, are
Speakers not woofers. They can offer some potent
midrange frequencies, when used correctly.

That's news I think. You're also a member or the leader of the house band, or planning to be? If so, the (coffee) bar is raised another notch or two. To have your name on the club is one thing. To also play host from the stage one or more nights a week takes things to the next level.

This should result in extra attention being paid to the front of house and monitor systems, especially loudspeakers and power amps. I haven't actually breathed any of the dust yet, but Speaker Builder's Loudspeakers for Musicians by Bill Fitzmaurice has some original horn designs, including some for the EVM series. The graphs in the book look pretty ragged; the author recommends (and I agree) a graphic EQ - I'd say 1/3 octave Klark-Teknik (old favorite).

Check out the book if you can, and see if the group here has good things to say about the designs. There's so much wisdom here - I'm glad to be here!

good tip dooper
if youre going to go all out and DIY i recommend looking at the back issues of AudioXpress. Bill Fitzmaurice has built new designs that superceed those in his Speakers for Musicians book.

particularly have a look at the DR12. fantastic mid cab that will blow your head off using the EVM 12L. just finished a pair, 140dB from 100hz up! definately need an EQ, particularly the Behringer DEQ2496 31 band with ECM8000 mic mates perfectly. be warned they take considerable time and skill to build.

Above 5k i am still looking for a good compression driver, BMS, TAD, JBL? anyone got any suggestions?

And for DIY club sub situations you cant beat the LABsub for sub bass

heres a freq response of the DR12 vs Turbosound TFS-780 1W/1m
