Gut Kick from Open baffle
« on: 20 May 2026, 02:02 am »
Hi,

I love open baffle, but I miss the gut kick that you get standing near a kick drum. A quality PA can give that feeling at a live concert. My understanding is that is the pressure wave, that OB struggle with since OB doesn't pressurize the room like boxed drivers in the bass region.

Is there a way to get that. Like blend in a sealed woofer in parallel with an open baffle woofer to get that 80 - 140Hz power kick compression, as well as get the amazing bass detail from Open baffle. That could be the best of both worlds.

Thanks,
Will

Our open baffle servo controlled woofers will easily give you that same gut kick that you are asking for.

What is the frequency range of the gut kick. Is it below 80Hz. I think I need to save up for one of those subs.

Thanks,
Will

I've found most of that punch is a kick drum around 50hz. If you can get that right without getting muddy overtones, you're good. And those OB subs certainly do that well.

What is the frequency range of the gut kick.

I asked Claude A.I.
The answer feels right to me.

A kick drum's fundamental frequency sits around 50–100 Hz, with the "punch" or attack transient carrying significant energy up to 1–5 kHz.
For a speaker to accurately reproduce a kick drum, it needs to cover:

20–80 Hz — the deep sub-bass "thud" and body of the drum
80–200 Hz — the main fundamental punch and warmth
200 Hz–2 kHz — the mid-range "click" of the beater hitting the head
2–5 kHz — the attack transient definition and presence

In practice, a speaker needs to faithfully reproduce roughly 30 Hz to 5 kHz for a convincing kick drum sound, though the most critical range is 50–500 Hz.
A woofer or subwoofer alone won't do it — you also need a mid-range driver to capture the beater click that gives the kick its definition and "cut."

I only play via roon and wondered why my system lacked a rich full sound. I turned off everything in precision audio control. All of the filters and when I disabled overhead management my music became full and my otica and double trouble sound bloomed and the room sounded lively. When I first started my system I dabbled with those settings and forgot about it. I am still working on room correction right now.

Hi,
I just put Claude's response into Chat GPT, I got the following response that goes further into why. Very interesting read.

Thanks,
Will

Claude’s answer is broadly reasonable, but it blends together several different perceptual phenomena into one bucket called “kick.” That is where things get muddy.

You are actually asking something deeper:

What creates the physical sensation and realism of a kick drum?

That is not one frequency.
The “gut kick” is mostly NOT sub-bass

This is one of the biggest misconceptions in audio.

People think:

chest slam = 20–40 Hz

Usually false.

True visceral kick impact is mostly in the:

60–120 Hz region

Especially:

70–90 Hz for many live kick drums
around 80 Hz for chest impact

That is where:

chest cavity coupling
body sensation
“punch”
impact
perceived speed

occur.

The very low bass (20–40 Hz)

This contributes:

weight
room pressurization
size
cinematic scale

But NOT usually the “hit.”

Too much 30 Hz can actually soften perceived kick articulation.

That is why some home theater systems sound:

huge
bloated
slow

instead of:

explosive
physical
tight
The real kick drum is multiple acoustic events

1. Sub/body component

Roughly:
20–80 Hz

This gives:

size
depth
bloom
resonance

2. Impact/punch region

Roughly:
60–150 Hz

This is the critical “gut kick” area.

This is where:

dynamic headroom
low compression
transient capability

matter enormously.

This is also why pro sound systems use:

massive cone area
horn loading
very high efficiency

in this region.

3. Beater attack

Roughly:
1–4 kHz

This creates:

definition
articulation
timing perception

Without this:
kick becomes dull.

Too much:
it sounds clicky and fake.

Important insight:
The “kick” is time-domain coherence

The realism comes from alignment between:

low-frequency impact
upper transient attack

If timing is wrong:
the drum sounds disconnected.

This is one reason bad sub integration destroys realism.

WGH,
You summed it up nicely!  As a percussionist, I couldn't have decribed the bass drum characteristics better myself.

Here are a few other factors, that either contribute or not, obtaining the "Gut Kick."

For example:
Studio recording and production makes a difference. I've heard many songs where the bass drum kick was lifeless, contributing very little dynamics to the song, where the "Gut Kick" was no where to be found.

Microphone Selection & Transient Response Different microphones have varying diaphragm weights. A large-diaphragm dynamic microphone captures low-end weight, while a sub-kick mic or a small-diaphragm condenser captures the beater "snap."

Dynamic Range & Compression used, affect the transient peak of a drum strike, demands serious headroom. However, heavily compressed or "brickwall limited" tracks, can flatten this dynamic impact, stripping away the visceral thump.

EQ & Phase, is another facctor, that either boosts or cuts in the low-end frequencies. For example, boosting 60Hz and 4kHz) shape the sound. Extreme EQ can alter the phase of the audio waveform, leading to smeared percussive attacks.

Transient influencers, producers often use envelope shapers to artificially enhance or shorten the initial attack and the sustain tail of the drum. It's very subjective, how this is approached by the producers. What they may like, doesn't always equate as the perfect score!  How many times have you heard songs produced poorly?

_______________________________________ _______________________________________ ____________________________

Beyond the studio, here's what you can control, improving bass reproduction.

Quality of Source material, like bit depth & sample rate and mastering of format too. I'll keep this area brief, but you get the gist.

Preamplifier & Amplifier have serious influences on bass reproduction, as well as many other outside electronic, electrical Influences.  The preamp, delivers the purity & detail. The amp delivers the power and headroom, for that massive demand, a kick drum requires. The amp should also dampen convincingly, by starting and stopping drivers on a dime. This contributes to the "Gut Kick".

The speaker system itself, plays a vital role translating electrical signals into acoustical wave forms.

Enclosure types, sealed, ported, or OB driver size plays a role. Agreeing with WGH, addressing the frequency character of a bass drum goes beyond the subwoofer, frequency range. For example, I hear details of my drums, even beyond what a microphone can pick up.

Drivers play a role too, larger drivers deliver fundamental notes. While smaller drivers provide improved beater definition coming from the drum pedal, as well as improved drum shell, head resonance decay reproduction.

Your listening room, plays a significant role! Room modes, standing waves, distortion from things rattling, even furniture resonances.
Noisey boundaries beyond your listening room, will increased the noise floor, not enabling to hear the beater or drum decay.

Speaker placement can provide either muddy bass, or articulate bass drum reproduction.

Lastly room treatment, provides the ultimate control of all frequencies, although bass, can really can mess up the entire portrait of music, if not treated correctly. Imagine a drumset, played in a room with untreated walls, ceiling and floor, in a 10'x10" room. It will overpower the room, booming with no articulation, of how bass drums really sound like. Treating the room will signicantly improve the accuracy, of a drumset.

All the above can assist with achieving, the "Gut Kick." Granted you can't do much with the source material produced from the studio. However, I thought I would share a few basic's, that can manipulate or contribute to how a song is produced. As you can see there are many other factors that can influence accurate bass reproduction. These are only a few examples listed.

How loud DBA does the music have to be to experience gut kick? I’m thinking ear damage level? Plus the recording would play a big role, some are recorded without much bass impact.

Plus I don’t see what gut kick adds to the listener’s enjoyment. At least for me I don’t like concert level loudness, ears can’t take it anymore. Just normal safe level listening is good enough for me to enjoy music.

Just out of curiosity, Anyone know of a few good recordings that I could use to test how loud I have to go to get gut kick?

Plus maybe the more flabby ones gut is could play a rule?  :icon_lol:

I use Bass Mekanik from my roon streaming. They have a warning message before the test begins. My hearing took a blast in 1970 I went to a Christmas concert in Ft. Lauderdale which was 9 hours and they were lighting off M80's. I had a hard time hearing for 3 days after.

The Legacy room at the 2012 RMAF was handing out a free CD with test tracks so I think sharing a track is OK.



"Dynamic Drums", is the last track on the free Legacy Audio Music Sampler Volume 1. This is the killer un-compressed drum track Legacy Audio was playing at lifelike levels in their showroom.
 
"Dynamic is an understatement. Played on what sounds like a conventional drum kit, this track starts off very quietly, with a majority of the beats done gently with Mr. Kaplan's fingernails on the drum heads. Then we hear some muted work on the cymbals that are glorious in the depth of the decay. Finally, there's a loud whack! as Kaplan strikes his snare with full force. He does it again. Then he launches into full attack for the remainder of the track's five minutes, and all I can say is this is what a real drum kit would sound like if stationed in my listening room."

I will have to check out the drum demo.  My open baffle system has all of the so called “gut kick” but when all the sealed servo 15’s are turned on, it goes to new heights.  After I get home from this week long work trip I will have to check it out.  Im tired of getting gut kicked at work.  Need some gut kicking at home.

I added a couple more cylinder bass traps so the front corners are covered floor to ceiling, actually it gives the bass more definition and impact, traps not only help with modes but help reduce cancellations from the rear wave that can thin out the sound. Drum and bass guitar from the NX Otica set up is the best I had in my room, but it’s a really long room so it needs to be really loud to feel it.
