Bludgeoned by Boominess in some venues

Our quartet performed at a venue in which we've wanted to play regularly. Acoustically it's not too good, particularly for those on stage. Very long front to back, narrow from side to side. Much of the stage wall material is corrugated steel.

We are at our loudest there which still isn't too loud. I am not a big advocate of drum miking, & we only request a little PA augmentation for the kick drum. (Vocals went through the house PA & our keyboardist uses a separate self powered monitor)

My rig consists of a Hartke LH-500, an SWR Goliath III (4×10"). In setting up we did a sound check in which I tested my own balance using my 30' cord. While playing with the group standing about 6-7' from my amp the sound was hard, boomy, abrasive, ill-defined in terms of pitch & dampening. I tried boosting treble control, boosting the Foster Horn level, only to find that the treble became brittle, rather than well defined. Notes appeared to overlap & smear in spite of my efforts to mute, dampen, or play stacatto. From a distance these issues didn't seem to be issues, but I didn't have the luxury of being 15-20' out front all night.

When what I put in as a player doesn't appear to come out aurally, I make unnecessary adjustments--all futile & frustrating. I encounter this issue frequently--always when on a hollow stage platform--but not to this extent. I am sure that practicing at loud volumes might help--but I don't have that option. (I saw Chick Correa at the Catalina Bar & Grill the night of his 74th birthday, & Patatucci's sound was more thunderous than I anticipated. I can only imagine the type of internal psychoacoustic adjustments he had to make to stand directly in front of his Aguilar rig & not unravel.

Here is an ancillary problem. The house PAs around here have scooped EQ settings. I saw the red EQ lights form a huge U & would have been shocked if I hadn't heard what it always sounds like when I listen to open mike night. Offensive chesty boom in the vocals & squealing brightness you can't imagine. Nothing natural. Our guitarist can't plug his acoustic guitar into the system without a significant ground hum. He has warned me not to argue with the people setting up the PA, but bad sound means less enthusiasm from the audience.

Normally we play in venues such as the 29 Palms Inn where we are sonic wallpaper, & our PA is simply a Peavy keyboard amp with a 15" woofer and $1.75 piezo tweeter set BEHIND US eliminating the need for a monitor (no feedback issues.) With the EQs set flat & at a distamce the amplification of vocals & acoustic guitar sounds like no ramification at all. Better than anything I've heard, providing that piezo isn't pushed too hard. (To me horns aren't emtirely natural sounding for voice.)

I am seriously thinking of making my own PA consisting of 4 small columns each consisting of a 10" woofer & several piezo tweeter in a series. With 2 of these columns set to the right & left of the drums (maybe a yard or so behind the drums) & the other 2 columns flanking the outsides. I would actually plug into this myself as well as keyboard & vocals. In theory we could be waned from using house PAs & at the mercy of those running them, b) very compact & transportable c) sound dispersed through out the stage so we all can hear each other & know what our balance is.

Some of the higher power Eminence speakers would be great, but much cheaper to just cannibalize my Goliath III cabinet. However Fender will not release the Thiele-Small parameters of those PAS Drivers. That makes building a single optimal size cabinet problematic. Any suggestions or observations?
 
The best way to control boom is with a parametric EQ. Set it for a medium width deep cut, sweep the frequency control to notch out the boom.
As for the PA, look at the BFM plans, especially the SLA Pro. They'll give a lot better result than anything you can buy for less than $1k each.

Because we play for the audience there was no need for EQuing 12' or further. The problem of boominess is strictly a problem regarding the discrepancy of bass output on stage compared to off stage. You adjust the eq so it's tolerable on stage, you sound like Chris Squier off stage, & of course the inverse. This is invariable with my cabinet. It got worse in that particular venue
 
First I would speak to the manager and tell him the sound man that set up the graphic is putta his mind and besides when you are there as a patron the sound is crap.

As for you, bass we flat or cut. Low mids bumped for definition, highs fairly flat. Make sure your cab back is very close to the wall within three inches if possible.

There is nothing wrong with micing at the drums always in all venues. Everything for that matter, in any situation. It's is more control FOH. There's level sliders that allow you to MIX the sound. ;) Just a hint of drums coming through the mix and a clean touch of bass, good vocal levels and full guitars and keys. FOH can be usually heard onstage in smaller venues in that suddenly the sound is filling the space instead of emanating from single (instrument amp) sources. which in turn can reduce sonic spl mayhem onstage. IMO ymmv.

Please read my last post regarding EQing. Levels at listening position were good but in front of my amp. Sasha!

If your not playing a stadium & you are miking your drums you are probably too loud. Professional musicians frequently compliment our whole approach to limiting volume to a sane level-- the last was Dick Dale @ the 29 Palms Inn

At this venue the person booking acts, hosting open mike & operating sound is one in the same. The problem is mych worse at Pappy & Harriets in Pioneertown as the owner operates the PA, prefers a huge bass & treble boost, & will probably ban acts who critique her "golden ears"
 
I'm not a pro, but in a situation like this, my intuition says to send your bass signal to the PA and have a small amp facing up at you to monitor yourself. It thus becomes the soundman's responsibility to get the crowd mix right, and you only need be concerned with being able to hear yourself. That does involve some trust in the soundman, which I'm not clear exists, but could be talked through in a non-confrontational manner.
 
My understanding is that the Goliath III is ported, in which case you might try plugging the port(s). This will probably significantly decrease the amount of low-end energy BUT it will also lower the cab's fartout threshold. So you need to try it out in practice before trying it on a gig, to see if the fartout threshold is still acceptable.

The four small columns idea is a very good one, as you can splay each pair of columns as needed to get a good coverage angle for whatever venue you are in. Imo it's worth the effort to use something other than a stack of piezos for the top end. If you might be open to a suggestion for an alternative that will give you a better top end (and which doesn't involve anything that I sell), shoot me a message.
 
This is honestly why for any gigs where I have good PA support, I'd rather have my Phil Jones Compact 4 Lite (4x5"), perhaps even on a chair, than my Bergantino 210 or any other cab. It reduces boom and makes it sound really even. Like someone else said, you might just have to go direct and get PA monitor in your face.

It's piezo or horns right? Personally I haven't heard a horn I like.
 
Also, please understand that from the standpoint of the audience my sound is good. If I cut the boominess I get too lean. The issue is where I am playing, & why the problem is more prominent in some venues than others. My keyboardist also has issues with sitting right next to his monitor & often uses earplugs. That might be worth trying.

I do have a friend of my luthier who offered to test my 10" PAS drivers to get the Thiele Small parameters. That does kinda open the door to convert my 10" woofers into a small 4 column PA.
 
You need one of these.

When your speaker cab sits directly on top of the floor on a hollow stage it (in essence) turns the stave itself into an out of control sub woofer via coupling. You need to isolate the vibration of the amp from the stage.

There are some rooms where the problem is totally acoustic, meaning that this won't help much. But those are more rare in my experience.

You are absolutely right. This problem invariably occurs with a hollow stage. Notes seem to continue sounding long after they sre dampened. You step out close to the audience & then it's not boomy at all
