MarkBK Posted April 28, 2006 Share Posted April 28, 2006 Acoustics and sound quality, all too often, are last on the list of concerns - fidelity is NOT something considered by most clubs....there are exceptions, but all to few of them even in a city like Chicago.

boom3 Posted April 29, 2006 Share Posted April 29, 2006 One of my favorite watering holes has 2 LaScalas, in corners, up at the ceiling/wall juncture,along with a mix of other speakers, the club is relatively small and does not have a dance floor. The primary DJ, whom I've know for years, actually knows who Paul was and is a bit of an audiophile himself. Years ago I frequented a bar that had one of the best sounding systems ever heard in such a small footprint. It's hard to make critical musical evaluations while intoxed, but this system was very fine. It had a JBL subwoofer in a huge wooden cabinet, a midrange and tweeter horn hanging over the bar and pointed out into the room and four identical main speakers spaced along the walls. Those main speakers? Bose 901 Series IIs. Go figure... Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted April 29, 2006 Share Posted April 29, 2006 I installed 4 LS in a club called Dick's Harem House back in the 80's. Yes it was THAT kind of establishment. Funny thing how most of the wires had to be routed through the dressing room. The ladies were a lot of fun in the afternoons. I was in early 20's then. I spent of lot of time there 'tweaking' their system that summer.[] Quote Link to comment Share on other sites More sharing options...

disco1999 Posted April 30, 2006 Share Posted April 30, 2006 They cut the mids so that bartenders can hear what you want to drink. Also, loud mids are more likely to give headaches when exposed for a long time. Quote Link to comment Share on other sites More sharing options...
DrWho Posted April 30, 2006 Share Posted April 30, 2006 Some more theory for you guys... A lot of inexperienced sound guys don't realize that the "punch" of bass also requires material in the 1kHz region. Try listening to the 40Hz range of material from a kick drum - it's dull and lifeless. In order for it to get punchy sounding you need to have the higher frequencies "trigger your ears". Our ears don't hear low notes very well so what happens is the high frequency tells your ears "hey, there is a sound occuring now"...and only then will you really be able to hear the low punch of the instrument. And by punch I am referring to that which makes you want to shake your butt... So what happens is your inexperienced DJ is thinking "MORE BASS ahhhh" and starts pumping the crap out of the low frequencies. But the system doesn't start sounding punchier until the harmonic distortion from the woofers gets loud in the upper harmonics (like the 1kHz region). But by that time it's sounding wierd because the amps are clipping everything and it's a distorted "trigger signal" - so not super clean...but it doesn't matter because it's so fricken loud by that time anyway. If there is anyone in the Champaign area I would be more than willing to demonstrate this effect. You DO NOT need SPL's over 110dB to have a rockin club. As far as bartender's being able to hear your orders...there are rather simple acoustical tricks that can be implemented to make it not an issue. Every venue is going to be different, but there is no reason why the sound needs to suffer everywhere. There are also long term effects of having really loud music...you introduce hearing damage in your audience which requires the system to get louder and louder in order for them to hear it. The said part is most DJ's are already pushing the system to its max, which means more equipment is necessary. In fact, I will never understand why every DJ I've run into feels the need to peak out every system they get behind...it makes absolutely no sense because all they accomplish is robbing themselves of headroom while forcing a threshold shift on everyone's hearing. The best way to make a system louder is to make the quieter parts quieter....not compress the crap out of the system to make the quieter parts louder. End of rant And for what it's worth, I'm not directing this at anyone here because I've never been to the club of anyone here...I'm just speaking for the huge majority of DJ's out there that I've run across. But if anyone finds themself trying to justify levels above 100dB then might I suggest taking an inventory to see if you really know what you're doing. (after an hour at 100dB your hearing has about a 6dB threshold shift - such that 100dB now sounds like 94dB. It only takes half an hour for 110dB and like 15 minutes for 120dB...so if you've got it at 115dB, then every 20 minutes you're looking at thing seeming 6dB quieter...so by the end of a 4 hour nite 140dB only sounds like 90dB...)

justin_tx_16 Posted April 30, 2006 Share Posted April 30, 2006 Because they weren't KLIPSCH!!!!!!! I actually went to a club in San Francisco the other night, the place is about 40 years old. They had Klipsch Heritage speakers all around. Probably put in when the place first opened too haha. They still sounded great though! Four of them are outdoors in the elements, crazy!

colterphoto1 Posted May 1, 2006 Share Posted May 1, 2006 To expound on DrWho's dissertation (well said Doc), first to address the kick drum sound. When mixing live music, and to an extent recorded tracks, the kick drum (driving force behind rock and club music) does indeed have two distinct tones. One, which I call the 'click' is the batter hitting the first head. Then there is the sound of the drum itself, the low tuned THUD. Most people micing and mixing the kick will forget about the importance of the initial attack of the instrument and even go so far as to turn down the treble on the kick- mistake. Secondly there is a phenomenon known as 'fader creep. When mixing or Dj'ing as the mixer's ears get used to the sound level, each succeeding track or one instrument at a time, the level will gradually continue to increase. If the engineer has started the mix at a resonable level, there should be ample headroom in the system to accomodate this. If not, watch out! When at the controls I always made a conscience effort on slow or mellow songs to purposely dump the volume considerably to give everyone's ears a breather and to score additional headroom. Just .02 from an old soundman. M Quote Link to comment Share on other sites More sharing options...

It's a bummer that kind of experience isn't easily passed on down to the newer generations...sound sytems are getting cheaper, which means more SPL for the buck - requiring more control from the dude riding the volume knob. I'm actually trying to get some school clubs (club as in group, not the dance house) started down here on campus where there will be a good outlet for training. Now to find real professionals in the field to come down and teach...I'm not sure everyone wants to listen to me talk for a year, lol.

I used a wooden beater on my pedal, combined with a pad which had a solid disk behind a lightly padded foam cover. The cover would wear out really fast so over that I put traditional moleskin to avoid a "knock knock" sound. This gave me definition to the max yet with a low thud, exactly as you describe.
