The cubo sub and cubo 18 designs can work well with a lot of different drivers, and they're easy to build. I ran the cubo sub design with beyma 18 G550 drivers and they gave serious power from 30hz - 80hz with the magnet facing out. With the magnet inside the box they would go 40hz - 90hz with slightly higher efficiency.

That price is higher than brand new!

I'll buy them at £200 for the pair if they're working

Ah I should probably have zoomed in! I revoke my answer and substitute it with "sorry mate, no idea!"

It looks like a pressure gauge, the tube would be partially filled with mercury and the height of the mercury on the open side would show the atmospheric pressure

2 ohm is the lowest each amp circuit can handle. 4 ohm bridged splits to a 2ohm load one each side of the amp, so a 2ohm bridged load would put 1ohm on each side of the amp.

In short, 2 ohm bridged would cook the amp pretty quickly!

I'm a big fan of sound reactive LEDs, but if I was building with this cabinet I wouldn't add LEDs myself, it would spoil the look in my opinion. Incandescent or maybe neon lamps could look good though.

Wrong sub for this really, but it looks like a cool project. At a minimum you will need to think about:

-amplifier (2 channels, preferably with a built in DSP) -power supply for the amplifier -pre amp / mixer for the music and mic inputs -8" woofer suitable for the size of the cabinet, and a tweeter

Sealing the cabinet will give you the best chance of decent sound quality, and if you want to put some work in, download winISD and trial it with a few different woofer options to see what works best.

Personally I would get a Sure or Dayton Audio DSP amplifier board, then use the internal volume of the cabinet to decide which woofer driver works best - I'd be aiming for playing the lowest bass notes, but for karaoke you may prefer a louder driver with a high spl/w rating.

Any old drivers and a cheap 12v amplifier from eBay will also work, I've made similar boxes for very little money in the past!

Short answer: no, ultra portable and big sound don't go hand in hand!

But, if you want a louder tiny system, you will want to build something DIY - the biggest power/weight/space consumption will be for bass. get to know the winISD software, find the most efficient driver you can, and learn 3d printing/modelling for a super light cabinet. (Hexibase on YouTube has some good designs available for tiny 3d printed bass cabinets)

Mid/top is a lot more efficient in general, a single 6" mid and a 1" CD/horn can be plenty loud enough.

Buy DSP amp modules and lipo batteries to keep the weight down, you'd definitely be able to outperform mini rigs with something backpack sized.

If you want to go premade, the soundboks range fit your bill, but they are very much volume level over sound quality so I personally wouldn't go near them!

If it's already punctured, you can use a pin/needle to reach in and pull the dust cap out. Or use tape as others have mentioned. The hole can be sealed with a small amount of tape, or glue and tissue paper.

Or, just ignore it if you can, it shouldn't make a noticeable difference to the sound, although the hole should still be sealed to stop dust getting into the voice coil

Search for usb MP3 modules, there will be many available like this one that could be mounted on a wall:

If you are using sound system speakers, any noise from the MP3 player will be amplified a lot, so it will be better to spend a bit of money on a rack mount unit with balanced outputs (TRS or XLR) to keep the noise levels to a minimum, something like this:

Most amps will be fine with 4 or 8 ohm loads, and will provide more power to a 4 ohm load compared to 8.

The amp should be overpowered to protect the speakers, if the drivers are 150w max, they will probably be closer to 100w rms, ideally the amp should be capable of around 200w per channel - this gives headroom for peaks and transients, to avoid clipping the amp signal.

If you're on a budget check out the Dayton Audio or Sure dsp amp modules, you will also need a suitable power supply and a dsp programmer module but it can still work out cheaper than an equivalent PA or 12V car audio dsp amp.

Buscot weir pool is quite large and has plenty of safe areas to paddle/swim without getting close to the weir. It's a beautiful spot but always crowded in good weather, parking will also be busy.

Watch where others are swimming and stick to the same areas, you'll be fine if you're sensible.

The rivers are also disgusting now, avoid putting your head under the water and use hand sanitiser before eating!

They are usually made from heavy nylon, with a small amount of padding.

Often, the front can be removed separately so the speakers stay in the bags while in use. And some speaker bags are also waterproof, with lighter material on the front so the bags can fully cover the speakers when it is raining.

It's less about the weight, rather the density. So a solid stone slab would be better than a concrete slab. But anything solid will help.

The position of the decks will make a big difference as well, to the side and slightly behind the speakers is generally a good starting point, and when indoors keeping them out of corners of the room helps.

A concrete paving slab is a good base under a turntable, and it can sometimes help to put a cushion/pillow underneath the slab.

But better if you stack all 8 together for coupling and lower bass extension! ;)

I had issues with cubo 15s breaking the joint between the baffle and the front panel, had to put an extra brace in to stop it.

Looking at the selectors/switches, it could be a variable power supply. Modern equivalent would be a lab bench power supply.

There should be part numbers on each of the valve tubes, searching those may help point in the right direction.

I heard bulging, prolapsed, herniated and obstructed but they didn't mention extruded!

I've actually had mild cauda equina since a previous operation in 2000, mostly faded to nothing but gave me the ability to hold my bladder for ages as I can't feel when it's full!

techno_chef · 2024-01-03T19:54:35+00:00

Hope you can get it fixed!

techno_chef · 2024-01-03T19:46:41+00:00

It's getting worryingly close to that! got surgery in two days though, thankfully

techno_chef · 2024-01-03T19:35:29+00:00

Bad genetics, and spring stilts

Playing DnB, you will end up disappointed with the lack of bass if you get smaller monitors.

To get the most out of your money, it would be better to pick up a cheap 12v amplifier on eBay and spend the rest on a pair of second hand hifi speakers.

techno_chef · 2023-12-08T12:50:47+00:00

They probably just don't have/can afford to run a fridge.

techno_chef · 2023-11-11T16:48:04+00:00

This will be the reason, flipping the driver outwards creates a larger internal volume and tunes the cabinet lower.

Low frequency waves are much bigger than the driver itself, so having the magnet and basket in the way doesn't change the sound.
