I guess that "Sonic Attack" by Hawkwind should fit in here. However, after the third engineer snuffed it, it seems they switched the generator off and stuck with Harvey on a regular bass when they recorded it!  Yes, that's a shame. It could have done with the kind of gut wrenching bass that Yello's Takla Makan has. |

With the advent of synths and the 5 string bass (29Hz) to compete with them, we got some low stuff. Some musicians achieve deeper notes by 'beating' two close bass notes together. |

If it isn't 0db (or very close to) & sub 30Hz, it isn't killer🙂 Older recordings don't have this. Unless churchy. Things went to about 40Hz and that was that. With the advent of synths and the 5 string bass (29Hz) to compete with them, we got some low stuff. Some artists (a few) go further down 'the deep' road though. Most 'hi-fi' speakers don't do killer deep bass. If we’re excluding anything that does not go sub 30hz you have just wiped off all 4 string bass recordings from this list with natural tuning. They go down to 40hz, luckily 40hz is achievable by most speakers, but not necessarily at 0db which might strain them😬 |

Just won't be gut wrenching (ctiteria of the thread), sofa shaking, floor vibrating, killer bass 🙂 |

Strain at 40Hz 0dB... That's why I have 2x these. Drivers are 15" Eminence Kappa Pro LFIIs. 1200W. I just tickle them in my Hi-fi application, but you do need a high damping factor amp to get the best out of them. Max cone excursion at 110dB is modelled at 2mm. However, they shift air in a long horn, so the coil / piston would likely punch through the cone before you hit that. But they are surprisingly good at reproducing music. I only use 20 - 90Hz. (When I first used them, as bass drivers in Tannoy grf style cabinets, with a separate compression driver/horn on top, I played them up to 1000Hz - sounded better than the fabled Tannoy 15" DC drivers!). They produce below 20Hz, just not much music to hear there. More of a flutter. 4.8m long horn path. I remember when Mike was here and we played some deep bassy stuff. He got up and put his hand on one of them. Expecting resonance / boomy feeling. There is none.  |

My solution is quite different from Steve's but with similar impact.
Each speaker has twin 11" long throw Eton bass drivers loaded with twin reflex rear ports. The Usher cabinets are large, rounded and extremely strong. There is no cabinet vibration. The speakers stand on custom Townshend Podiums with their 160kg mass 'floating' on damped springs. If pushed, they swing gently at less than 1Hz. They are driven by a very high current Belles power amp which dismisses their 4 ohm load without getting any hotter than lukewarm. The combined effect gives very deep, very tight and punchy bass without overloading the room.

Yes that describes your bass well
Believe it or not my bass is nearly on par but captures the timbre of bass extremely well

He got up and put his hand on one of them. Expecting resonance / boomy feeling. There is none. You must have a very understanding partner, is the external bracing to stop them exploding. Dedicated music room solves the understanding partner issue. I put the extra bracing on before taking the whole lot to Scalford (own Hi-Fi gear show) - way back. Looked the part too. I thought it might be needed at show volume levels in an exceedingly large room. Was a total non issue. They pressurised the room easily. I removed it all to lighten them and take them into the current loft room. Here they just are just tickled. The original Tapped horn idea is by Danley sound labs. The normal dip in Amplitude of a driver in a long horn, around 70 or 80Hz (if I remember correctly), is filled in by tuning the rear driver ouput throw to amplify that region. They make them commercially for indoor and outdoor sound reinforcement venues, where full frequency is required. www.danleysoundlabs.com/products/subwoofers/specialty-subs/They make all sorts of shapes and sizes of gear. They use high grade baltic birch plywood too. Very innovative and helpful to the DIY audio community on the fora. I made a single 15" tapped horn unit for a pal in Kent last year. Operates 60Hz and below. 1.1m x 1.1m x 40cm deep Runs off a Bridged Crown amp (silly power reserves). Huge damping factor. We used Anti-mode self learning room correction - Same I used x 2 when I had analogue crossovers. Evens things out nicely. He's very happy. Has a very hi-end set up. Love a bit of bass🙂 |

Thanks for the info., I looked upon Danley and they do some serious commercial gear, very interesting. Sadly I am limited at present to the lounge, so a wardrobe in the corner is unacceptable to SWMBO.

Gone Gone Beyond - Little Moon Some nice potent bass on this track.  |

Here some plots for some tracks. It's the red max hold line that's interesting. The high frequency drop like a stone is phone microphone limitation. When I measure sweeps with phantom calibrated mic there's plenty up there . 1. Solen har gått ned - Veronica Maggio  Nice energy levels 23Hz 2. Basstronics - bring the bass back (sort of music🙂)  The bassiest high amplitude you'll find anywhere. Sofa bounced to this. 3. Organ sonata no 1 in D  Pretty low with some energy down to 20Hz and below. 4. Rachmaninoff: Prelude in C |

 Lots of sub 20Hz deep fluttering can be heard and felt for Rachmaninoff. The deepest so far, but quite quiet. I've now got pretty good at recognising what's deep what's not. I can tell 30Hz from 35, 25, 20 etc. The phone app seems to measure these pretty well. |

Yes, Bassotronics give the lowest readings I've yet seen when using the spectrum analyser on my tablet. I'm sure they use beating to get ridiculously low notes at lower energy too.
At some point I'll try the Saint-Saens and Durufle recordings with some very grunty low bass. The Davies Symphony Hall in San Francisco has one of the largest Rufatti organs in the world and recordings made there are incredible.

As a reference I played the Basstronics track on a Sonos One  Around 40Hz is the lowest they play. Here's the Rachmaninoff one too,  Yup 40Hz and then drop like a stone. The sound is still quite bassy, but not killer😂 |

This one has significant energy all the way down to 20Hz  I don't find it as appealing as her Freedom track. This one too, reggae 🌿  |

Ouch - that's an epic moment in the film. What was she thinking? What's the rest of the album like? I haven't listened to it yet. Blue Bannisters - Lana I'm listening more now. Trio omitted, I like it. The quality of the recording is about the same as Born to Die. Which for me means back on track, after Chemtrails. I like some of the songs on the latter, but find the recording quality sub par. Some of the tracks have 32Hz bass. There's even some energy below that, but at reduced dB. Are they afraid they'll blow someone's 8" sub perhaps?😂 |

There are some good recordings on Lust for Life. The worst by far is Ultraviolence, recorded in a bathroom. Shame, as it features some great songs.
