Poseidon Sound System: Commanding The Sound Waves ;)
Our Custom Built System
We wanted to do something a little different from the audiophile route — the design brief given to young talent Bosco Taylor was to have a system that was still up there for Hi-Fi listening but also great for live music with almost zero power compression over time due to the triple stacked coils, super low distortion and as wide dispersion as possible.
We were keen to explore the newest technology rather than finding old components- which is more in line with our forward thinking approach to the venue. We settled on a design that uses the best components available today whilst not shying away from DSP to tune them.
We’re extremely happy with the sound stage, the definition and the dispersion from having a horizontal horn design and hung from the ceiling, the technology is similar to the Danley Synergy Horn, however the focus is not all out Sound Pressure Level (SPL) but using the finest PA drivers available in order to create a more HiFi sound but still be suitable for live music with excellent impulse response characteristics.
In our testing we tried some valve colouring but it sounded better without, due to the clarity of the drivers. We are currently testing Linear Research amps alongside offerings from Lab Gruppen and Powersoft to begin with. As with any system we will refine over time and test new components but even with the current amplification the system shines.
Their high fidelity also suits high quality mixers such as the Isonoe 420 and really exposes the quality of phono preamps which is something we are continuing to explore.
Tops — Unity horn loaded with dual 15″ tetracoils (18 sound) and a co-axial 1.4 B&C DCX
Subs — 18 Sound 18” tetracoil
It was our third iteration, after attempting a unique fibreglass moulding (as seen below) that unfortunately didn’t have the density to reduce vibrations with such a large horn. We ended up with birch ply due to its superior resonance characteristics. We will be painting them Klein blue with a special hand painted design on the horns :)
We chose horn-led for a number of reasons, one of the main one’s being for a super wide stereo image and dispersion, where we focus on more people in the venue being in the sweet spot for our ‘democratic sound’
A better phase coherence
When all sound sources originate from the same point, the sound waves maintain better phase alignment, which can improve the clarity and detail of the sound, especially at the crossover point between the speakers and the driver.
Improved Dispersion
A single horn can control the dispersion of sound waves from both the 15-inch speakers and the compression driver, resulting in more consistent coverage across the frequency range. This enhances the ‘sweet spot’ of the stereo image, providing a better listening experience across a wider area.
Reduced Interference
With all sound sources originating from the same point, there’s less chance for sound waves to interfere with each other, which can sometimes happen when separate speakers are used.
Streamlined Design
A single, unified horn offers a much cleaner look and uses less material and less space, also making it easier to transport.
Reduced Distortion
The horn can help manage the load on the speakers, reducing distortion and allowing for higher volume levels without compromising sound quality and keeping consistent clarity (think being able to hear someone talk when it’s loud)
We’re super happy with them, but we’ll be consistently making improvements to the venue, acoustics etc as it’s a major passion for us, in fact it’s why we wanted to open a venue in the first place.
