    Posted: 13 April 2025 at 10:47pm

Hey everyone,

We want to take the leap to build our Dub Soundsystem. After years of collecting Reggae/Dub dubplates and selecting sometimes, we want to bring proper sound to our local scene – where there’s currently no active Dub system.

We’ve done some initial research and budgeting, and we’d love to share our current plans and get your input.
We are Dub Selectors so we're very interested in frequency separation — both as a tool for mixing music with a focus on individual frequency ranges, and for manipulating those frequencies to achieve a clean sound, or even cutting them entirely.

At least we want to built a 4-way system, but preferably a 5-way system for propper frequency control. A 3-way system is out of the question, since sub-frequency separation is essential for us.

Our budget is around 5,000 EUR, and we're trying to get the most out of that. That said, we’re willing to invest more if it’s necessary to build a proper, quality sound system.

In terms of experience: one of us is starting from scratch, and the other has some hands-on experience with DIY furniture building and basic electronics.


Our vision:
A modular, hi-fi 5-way system with at least 2x 18" subwoofers, full control tower (preamp, mixer, FX), and enough power for both indoor sessions and small outdoor gatherings.


So we now have a few questions:

  • Sub Recommendations Super Scoop, Tapped Horn etc.? 

  • What for the kick/mid

  • Preamp(-builder) recommendations?



We’re still learning and would love to get feedback from anyone who’s built their own rig. If you have tips, photos, or even mistakes to avoid – drop them here!

And if there’s already a thread on this exact topic, feel free to drop the link here as well.

Thanks for your help – every tip is appreciated

Merci & thank you!

why 5-way ?

why not just 3-way + sub ?

personally i would just buy ( ACTIVE DSP ) 3-way tops and build my own subwoofers.

as a DIYer most of the money you save is by building large boxes yourself, in other words the subwoofers.

find a good subwoofer design that sounds good to your ear and clone it.

you can look at RCF NX 985-A tops for example.  look at what subs RCF recommends they should be paired with, and then just build a copy of those subs yourself.

RCF wants crazy money for the subs - i bet you can build ones that work just as well for 1/3 of the price.

building good tops yourself is more difficult and the tops aren't as expensive so you won't save as much money by building them yourself.

At least a 4-way system is commonly used in Dub for propper frequency control.
A 3-way system is out of the question, since sub-frequency separation is essential for us.

can you post some links to systems that you consider good ?

i am having trouble visualizing it.

i mean i had a 5-way DIY system in my car and i have seen 6-way DIY synergy horns but i have never seen a prosound system that was more than 4-way.

in fact never seen one that was more than 3.5 way so to speak.  either 3-way + sub or 3-way with a coaxial compression driver.

if you do a 3-way with a coaxial compression driver and add a sub you're technically at 5-way now and that still makes logical sense.

but i get a feeling you are talking about something else.  

curious to understand.

It looks like the goal is not a good sound but playing around with the Pre-amp in the first place ( no offense ). 

It is very difficult to not have phase issues with Preamp built in Crossovers. 

I would go for 3-4 ways, check the Lavoce 2x18" plan which is quite a loud sub and cheap. You might find tops there, too.

That is deffinitly not true - how you come with a guess like this.

We definitly want a propper soundsystem with a good hi-fi sound, and that's why we wnat to invest a few thousand euro, but just do not want a 3-way system because of subbass/bass-seperattion.

Thanks for the sub recommendation!

Based on the above setup, A pair of Double Eighteens to pick up where those Scoops leave off would give you the High Fidelity Sound you are seeking. There was a guy that had a similar setup as above around 35 years ago that, used Double Eighteen Reflex to enhance the fundamentals in which, the Scoops could not offer. 

You will have more options using 18 inch woofers than 21 or larger, due to the wide variety of options to choose from. 

The link below should help you along the way...

For those who are not familiar with the concept / art form, the crossover and preamp is used as an effects device and the system is played like a musical instrument, extensively modifying the programme material. 5-way systems are good for this.

every forum has their own niche.

on AVS they build subs that go down to single digit hz.

on DIY they build synergy horns, ribbons and tube amps.

on ASR they fiddle with DSP and 3D Printing, Hypex and Spinoramas.

on PE they make everything out of Dayton and GRS drivers

on here it's all these scoops, bullets and dub.

it doesn't matter what year it is - that stuff will always need to be explained to anybody who is new to the particular scene.

Maybe wait and learn before trying to be knowledgeable about something you nothing about. What you are actually doing is derailing a thread which helps no one.
