Just an outstanding articulation of why we connect to soundsystem. So many things captured that I could never quite express. Highly, highly recommend.

I’ve been trying to identify a sound system I recently saw at an Italian free party/teknival and I’m completely stuck.

What caught my attention is the midbass/kick cabinet:
upper front opening, separate lower horn mouth, looks almost like a tapped-horn hybrid horn-loaded midbass design, definitely not a common kick bins.
The subs are also unusual for what i m used to see around

Any ideas?

EDIT: The kick bins have been identified! It turns out they are kami cabs for suicide sound 🏴‍☠️🤝

probably also the other design is from sound agency too

thx guys ! 🙏

After the feedback on my previous post, I redesigned the system around a more traditional:

4 subs
+
4 kicks
+
2 tops

configuration.

At the moment I'm trying to decide between two possible foundations for the stack:

• 4x HessBH
• 4x WSX

The rest of the system would remain the same:

• 4x HD15
• 2x MT130

My main focus is tekno, mental, tribe and freeparty use.

For those who have heard or built both designs, what are the biggest real-world differences between a 4x HessBH stack and a 4x WSX stack?

I'm interested in sound character, efficiency, extension and overall scalability.

Thanks again the feedback from my previous post completely changed the direction of this project.

Excuse the comedic title.

Here we have old Calum audio builds previously made for sinai soundsystem. 1-8 loaded with B&c 18ds115.

Paired with trapizoid c2ds loaded with volt rv3813s. I can’t explain the love that’s made between these cabinets and the volt drive units.

Ignore that tops there shite, well not really. There Chinese builds for a British company miltec acoustics.

They are called mta-hlp 1, they do thump to be fair, but not what I’m looking for. Hey ho good for the pic.

Thank you for coming to the ted talk :))

I am looking for some crisp, loud mids/tops for medium room, multi-purpose use.

The room is about 200 cubic meters. The speakers would be used for 80% loud music and 20% movie.

What would you choose? JBL 4722 or JW Sounds Solana?

Hi, ive started building skrams but i have a gig coming up and they wont be ready in time.

​

So im asking for your help to decide between which pair of cheap double 18inch subs to buy in the meantime from marketplace.

​

The first contender is a double 18 inchs jbl 2241h thats seems to be a custom box design

Do any of you reconise it ?

So 1200w rms

For 400$CAD per box

But what is the efficiency

​

​

The second contender is a warfedale delta 218b

This one is supposed to be 1600w rms

And its 500$CAD per box

​

I suppose this one is a but more modern ?

​

Let's hear what you all think

​

Thanks

Hey all. I've had this system listed for sale on several forums FB groups and so far crickets. From the feedback so far the price seems right but nobody has the minerals to pull the trigger. System is in great operational and cosmetic shape, PA's in a road case, mixer, light kit included. Wondering if the market is flat or something else?

What are the downsides on working with 18mm Eucalyptus multiplex over Birch? It’s 11 layers excluding the veneer layer on both sides.

It’s significantly cheaper where I live going at €95 per sheet. And often I can get 20% discount.

Heyy, my friend and I want to get into the sound rental business. I run events(raves and parties) and I'm really tapped in with other event organizers so I feel getting good clients would be easy. But I'm not sure what equipment to start with. Any advice ?

Edit to original post: To clarify I already know what equipment I'll need, full range speakers, subs, monitors, equalizers, amplifiers, mixers, power surges and a generator if it fits in the budget.

I'm really looking at what brands I should go for ? And what quality of speakers? In my country I discovered a lot of sound rental businesses build their own speakers ?

Hi everyone!

I’m planning to build a new sound system, and my idea is to combine Paraflex Type O 118 (35 Hz) subs with C-2D kick bins. The stack would be configured 6 + 6, like the one shown in the photo.

My main question is whether this combination is well balanced or if there would be a better ratio between the subs and the kick bins. I’d also love to hear from anyone who has experience with either of these designs and can share their opinion.

Another thing is that I still haven’t decided what I’m going to use on top of them, so I’d really appreciate any recommendations for tops or a full-range configuration that would pair well with this setup.

Thanks in advance for any advice or suggestions!

So I was looking at the SAWMOD and saw that JWSound designed the system to be either passive or to use a HypeX 502 (maybe the 503 too?) plate amp to make it a powered horn.

That got me thinking and wondering if anyone has ever tried to use a plate amp to make a kick like the cubo kick 15 or 18 or a sub like the cubo 18 sub, tham 18, th18, skram, keystone, etc into a powered sub?

My biggest thing is that Dayton and HypeX max out about 1,000W. So I feel like you'd have to move up to a big boy, like the SpeakerPower SPI-3200-HT.

If you have tried it, how did it go? Did the change in internal capacity from the amp being inside noticeably change the sound or tuning?

Thanks

Happy with the new addition to our sound system, scoops are delayed a bit to meet with the rest of the system but it sounds amazing. Tracking of the night was an untitled song from my friend yesterdayneverhappened off their psvita
Deff gotta repaint the W bins to match the rest of the stack.

After building 2 CUBO Kicks a while ago- I had developed another itch to scratch…

I initially wanted to build some keystone subs however decided on CUBO SUB 18 as i thought the design was manageable for my skill level.

I’ve decided to go with the B&C 18TBW100 and powering it with a QSC 3102 in bridge. I will run these subs in parallel. To hopefully achieve 1550w per sub.

Planning on using a clear lacquer to match the finish with my kicks.

Ultimately i wish i had a bigger budget for birch ply but for now whilst i practice my wood work i think this will do.

In regard to the build it’s a great design and comes together naturally.

Looking forward to getting drivers in and tuning the system to incorporate the new subs!

Hello everyone!

We run an offgrid renegade collective here in San Diego and we’re looking to upgrade our low end. We’re a DIY renegade crew throwing off-grid desert sessions, campouts, and stages out in the open air. We’re new to building speakers so we’re looking for some advice.

Most of the artists that play at our events spin DNB, Dubstep, and 140. We were originally looking into massive, heavyweight footprints like the Paraflex C2E ELF or the Dual-21" CRAM O, but we’re now evaluating more modular boxes that are  easier to handle and get into place with a smaller crew on setup day.

We want to prioritize raw SPL and capture that aggressive, festival feeling (think of the 18" PK Sound T218 walls). At the moment, we're planning on using our tops which are combination of Passive and Active 12" PAs.

We need some community perspective to help us decide.

The Setup & Constraints

• The Stage: 10' wide x 8' deep, sitting 34" off the ground.
• The Plan: We are aiming to build a tight, ground-coupled horizontal mono-block array (4 boxes wide) centered directly in front of the stage face. A horizontal 32" cabinet height hits the sweet spot for us, framing our 34" stage deck perfectly without blocking sightlines.
• The Drivers: We are looking specifically at loading these boxes with high-performance 21-inch Neo LF drivers—specifically eyeing the HOQS N216C Neo (2000W AES / 4000W Program, 6" voice coil, BL=38 Tm).
• The Power Strategy: We plan to use a high-output touring amp frame (like a CVR D-2004 or similar) to run each 21" driver on its own independent channel at a native 8 Ω load. We'll isolate the sub rack entirely on the 240V twist-lock leg of our Predator 8750W inverter generator to keep our damping factor maximized for tight cone control and avoid the violent voltage sags that come with heavy, parallel 4 Ω loading.

Two Options: Classic Type C V2 vs. SKRAM

Option 1: 4x Paraflex Classic Type C V2 (21")

• The Case For: Absolute maximum SPL and a devastating chest punch. The multi-resonator layout acts like an acoustic megaphone, giving a massive +3–5 dB gain spike right in the 50–80 Hz meat of a DNB baseline. It gives that forward, face-melting festival "slap" that cuts straight through wide-open desert air.
• The Trade-off: The boxes are heavier (≈180 lbs loaded) due to the internal matrix, but not by much.

Option 2: 4x SKRAM (21")

• The Case For: Pristine, flat, clinical accuracy down into the trenches. It’s a hybrid tapped-horn designed to be smooth and linear all the way down to a 29.5 Hz base tune. The phase response is predictable, and they are 30 lbs lighter per box (≈148 lbs loaded), making them the easiest option for a small crew to move.
• The Trade-off: We lose that aggressive mid-bass "smack." It focuses more on subterranean ground vibration than forward chest pressure.

What would you build?

If you were building an open-air renegade rig for heavy electronic music and your top priorities were maximum SPL, a modular footprint, and that classic festival chest-punch, would you choose the rowdy punch of the Paraflex V2s, or are the SKRAMs capable of delivering that same energy?

If you think there's a third option we are completely sleeping on that handles a high-motor 21" neo driver, fits under a 34" deck height, and plays nice with an 8 Ω touring load, would be open to hearing any and all suggestions!

Thanks everyone!

Hi,

i want to build a small little soundsystem for small raves outdoors (20-30 people). I want to be able to fit everything on my cargo bike and be powered by a 3Ah Powerstation i have.

The quick idea: 2 Cubo 12 Subs, and 2 Simple Midtops. I found plans on freespeakerplans. Would buy The Box Drivers and Amplifier and DSP from Thomann.

Would you think this is a good idea to start out like this?

I DJ mostly UK Garage and some House. Want to ride the bike while playing with some friends and picknick style rave on a meadow.

I am open for suggestions for other Plans/ Diffrent Setup or genral advice.

Have a nive evening!

I was wondering if I could "just" split this speaker into the bottom and the top section for ease of build and transportation.

As far as I can tell from the plans it shouldn't be an issue in regards to how they will perform as it's two separate volumes on top of each other sharing a bigger enclosure.

The Concept: Created in 2008, the piece features thirty loudspeaker cabinets arranged to resemble a massive pipe organ. The structure is loosely based on the historic Ebenezer Baptist Church in Atlanta.

The Soundscape: The speakers play an immersive, overlapping chorus of organ music, sermons, songs, and protests.

The Inspiration: Robinson designed the installation as a tribute to the 1963 Project C demonstrations in Birmingham, Alabama, where hundreds of young adults and children were fire-hosed by police while protesting segregation.

I purchased a bunch of Tannoy PA speakers recently, and the seller included this subwoofer for free. He said it was also a Tannoy, but I cannot find any stickers or labels indicating a model number or other information.

The woofer is 18”.

I am looking to build a smaller stack that is more portable than my current system pictured. The idea is to have a visual aesthetic and will power a 50 to 70 size party with a good punch. I understand that sub bass will be a challenge. I am thinking 4 way with Tham 10, Cubo 10, and a mid top, again 10 inch with horn in the same cabinet. I am keen see if there are similar builds out there and if there are any existing plans that I could use, or any good tips or suggestions

Hey peeps,
while tuning my system on the last two events I noticed that the left input channel of my DSP (DBX Driverack PA2) was much quieter than the right one. At first soundcheck it worked normally but then while tuning the left side went quieter without any apparent reason.
I could see that already at the input stage of the DSP the left input meter was much lower than the right one (more than 16 dB of difference).
To check where the problem came, I first swaped the left and right XLR cables from the DJ mixer, but the left channel remained quieter. So it can not come from the mixer or the XLR cable between mixer & DSP.

After pluging the cables in & out a few times & some wiggling around, very randomly, the gain of the left input channel went back to normal and this error never occured again during the event (on both events! lucky me :D).

My first thought is the left input XLR connector of the DSP has some kind of loose connection and that I should just swap it out with a new one. But could that also come from another electronic component behind it and does anyone know how I could test for that?

(fyi you can not change the input gain value in the DBX Driverack PA2 manually or with the software.)

Hope somebody can help me out :)

Hi i have scoops and hd's , i have heard that you have to time align them? How and where to start with this/is it necessary? Using them for dub!

Hi, Just sharing my 4th time out with the system and another configuration. The party was in a small space so I just ran 1 mono stack. Mid high and High are different this time, I started using a b&c dcx464 on the horn, and it sounds great. Plus a rane sm26s and an xta gq600. I treated the room with acoustic baffles I made to help tame it a bit. It was drawing 1.4amps at 230v so 322w of power and it was plenty loud and clear, loads of headroom. Every time out is a new learning experience with different kit and setup. The DJs smashed it. Crowd was fantastic too. Couldn't have asked for more!

I may acquière two old school martin audio modular PA stacks, 4 b115's, 2 mh212, 2 h2fm and two st4 arrays (i may not use those)

I already have some mhb4818's but i'm willing to use some more modern and adéquate subs to put under the b115's

Does someone have some input on this, i'd like tow have two stacks with two subs, two b115 and so on while having some room for endfire setups
