Gweike Cloud Pro 50W Laser Review & Feature Build

how much bass could possibly come from something this small could this for instance replace the subwoofer in your car well there's a new arrival in my Makerspace and I did kind of Promise doing something cool with the other one of these speakers so let's do something cool [Music] today's video begins in the garage as I make way for this 12 pound box sitting on top of this 132 pound crate and on the off chance the name GV doesn't ring a bell the majority of their 18-year operation has been in the industrial sector producing just about anything you'd otherwise find in Tony Stark's man cave the GV Cloud family Blazers is the company's foray into the consumer Market competing with the likes of glowforge to deliver a powerful bench top solution this particular machine is fitted with an internally cooled 50 watt CO2 laser which as it stands has nearly 10 times the power of my diode driven unit so if cutting through a quarter inch of plywood insects slow passes isn't your jam considered the following your typical diode laser will operate somewhere just below the ultraviolet and the 450 nanometer range which is best suited for Engraving anodized metallic surfaces a CO2 laser on the other hand operates at an infrared wavelength of 10 600 nanometers more so along absorption spectrum of textiles polymers Ceramics and natural materials like wood in other words it is good at vaporizing these things which is in fact how we achieved a laser cut so that's this big right here and I'll scatter some more information about it further into the video for now let's have a look at the little guy and to get this barely inch and a half piston down into the sub base without simultaneously reducing it to a one note Wonder I've gone the impedance matching route if you recall what I did with the other one of these drivers last year the strategy was to exert nomadic impedance of the Piston as a form of Excursion control this time I'm going to acoustically amplify the backwave which for starters requires a lot more space and a lot more precision as you can see here even the slightest variation in the angle of the taper means a world of difference in the compression chamber and the same holds true for the resulting performance with the lasers 510 by 300 millimeter processing area doubling as the enclosures footprint I was able to fold the one and one half needle on expanding waveguide design to extend the driver's in-room performance just shy up 60 hertz however when I simulated this very same alignment Corner loaded in the back of my Chevy Sonic well let's just save that while I trust my software I kinda like to hear this to believe it and that's exactly the plan though before I show you what I have in mind there's still more to unpack right away several of the accessories arrived aboard the laser as it were and these include a 5 inch diameter nylon fabric air hose a storage box full of bits and pieces a six inch diameter air hose with some clamps and fittings and a set of three cables power ethernet and USB the other box was packed full of this inline duct pan for improved exhaust and a rotary attachment for processing cylindrical objects actually make that two separate size rotary attachments each with an interchangeable scissor lift here GV could have obviously gone the cheap route just to list the feature but it's precisely this level of accommodation that says these tools are for actually getting done lastly at the very bottom of the crate we find a stash of assorted laser friendly materials and here is my live action take on the complete list of items included when you order the pro needless to say for a complete CO2 solution this is not a lot of baggage and I say complete given that the water chiller and the air compressor is built right into the system essentially heavy duty metal case anyhow for the sake of Mobility I modified my cart with a 98 by 57 centimeter bench top to match the machine's footprint and these little bumpers to protect the corners there now I can easily wheel this thing around the house which matters because if you're sharing your workspace with let's say a car making efficient use of seemingly no space at all is just part of the adventure also only options that I prefer to laser from the comfort of my office or in this case simply get acquainted with the Control software well that too is an option mind you the wife acceptance factor that I'm working with here is well over nine thousand nine thousand there's no way that could be right next let's talk about the fact that when cut certain materials will produce hazardous fumes and this is where the exhaust comes into play the inline fan is mounted by the workbench and since they included 6-inch diameter air hose is quite short I've sprung for a length of this four layer premium stuff from AC Infinity also here's a few brackets that I made for the occasion once in place the house travels from the fan across the garage and out into the open the reducer on the other side is fitted with the included 5-inch diameter hose which in turn connects to the laser so anytime I want to use it I just roll it out of the corner hook up the exhaust connect to a computer running light burn and it just works the machine's controller is recognized immediately without the need for any third-party drivers or other mandatory software which also means that I can get on with whatever it is I'm doing literally seconds after the hardware handshake what's more with the 5 megapixel camera built right into the lid it's even more convenient to arrange tool paths along the processing area for acoustic builds MDF tends to be my go-to material so I'm very interested to see what it takes to cut through this quarter inch sample here I've prepared a test running the laser between 50 and 80 power with travel speeds between 5 and 20 millimeters per second the results are impressive to be sure as you can see here even at half power the laser punches through in a single pass that's it we happy yeah we happy indeed at a quarter inch or 6.35 millimeters per layer I can achieve my target cross section in only 13 layers and these acrylic samples from the included pack can become the outer walls for AC through aesthetic with gaskets on either side to help seal the waveguide Shall We Begin I already did and for an even cleaner finish I decided on two passes per cut in fact with a fully motorized laser head I can automatically run the first pass drop the focal point run the second pass and still complete as many as three sheets per hour making some plug that's actually doable as a weekend project what's more the machine has proven extremely reliable with unrelenting consistency from one tool path to the next further alluding to its industrial pedigree and the fact that it doesn't even impinge on my limited work area speaks volumes for the overall form factor not to make a joke of it but even the air exhaust doubles as a bumper for the car door anyhow given the sheer speed at which the laser cut through all that MDF I decided to double the fun and build a pair of these so for all intents and purposes that's 19 centimeters of MDF and acrylic that I cut through in a span of a weekend the last thing on the chopping block is a roll of disclosed cell phone another polymer and even at minimum power everything is cut in just a few minutes needless to say if you want perfect air seals to line your see-through panels or gaskets to go around the back of a driver a CO2 laser like this one is the perfect tool for the job anyhow let's get everything put together and here I'm using the same type of an alignment grid as I did for the tapped horn project a few months back this time with a total of 26 screws providing both the temporary clamping force and the alignment from one layer to the next as you can see here everything fit together perfectly and with all the MDF pieces glued the entire thing is coated with a few layers of sanding sealer ordinarily this would also involve a bit of sanding but for the purpose of this project I'm only looking to encase the material in some polyurethane next I'll want some binding posts around the back and here's a little guide I made for the pilot holes once they're in the cable is threaded through to the compression chamber at which point it's on to the gaskets here I could have obviously cut the foam into more manageable pieces but the same like more fun mind you not as much fun as peeling all this masking paper from the acrylic sheets or attaching them with a total of 104 metal screws anyhow let's see if it works [Music] how it works [Music] yeah that's good so now let's get the drivers in the right way around and get to some actual testing right away here's the in-room frequency sweep no major surprises there in fact the psychoacoustically smooth response correlates well into the upper mid-range for the in-car stuff I set up an MK 300.2 from Audio Dynamics which despite the miniature size can still deliver nearly 400 watts of clean power into a 4 ohm load but today we'll only need about two percent of it here's the sweep and well strictly speaking 60 hertz is the threshold for sub bass meanwhile as predicted this thing retains at least a modicum of presence down into the mid 50s needless to say you'll want to get your listening gear on standby for demo coming up here in just a moment in the meantime I have some final thoughts about the machine not the least of which is the sheer amusement and the fact that I can make stuff like this right for my garage just hanging out enjoying a rainy weekend in fact let me just press a few more buttons and there an edgeless sign sure why not evidently making stuff like this is a business in itself and that's really the underlying sentiment this machine means business its accessories mean business the thing sets up in a matter of seconds it doesn't require constant maintenance it doesn't stop in the middle of a job and most importantly it doesn't cost me my time instead it works beside me tending to its assigned task really the only thing that I could possibly gripe about are the USB type A ports along the back require the use of a somewhat uncommon cable especially if you need one longer than what's been provided other than that the machine is solid and big thanks to GV for sending it out now then All That Remains is the demo and for the first portion I will run the speakers full range in Stereo then once we get back into the car I will set them up as a subwoofer with a pass band of 40 to 80 Hertz so go ahead and get yourself situated for a bit of listening and as always feel free to drop a comment about your choice of audio gear and your overall thoughts on the project I'm also interested to know what is the smallest diameter-wise speaker that you've ever been impressed with and under what circumstances finally don't forget to rate the video as you see fit subscribe if you're so inclined and I'll see you in the next one cheers [Music] [Music] foreign [Music] [Music] thank you [Music] [Music] [Music] [Music] thank you [Music] thank you [Music] that's really yeah [Music] what for listening positions [Music] [Music] okay [Music] like I said it has good room to it it has a strong presentation oh yeah [Music] notice you don't get this over here turn on the other side nothing here lots of image back here yeah [Music] I like this track too [Music] [Music] foreign [Music] [Music] foreign [Music] [Music] oh another [Music] foreign [Music] [Music] this actually has some output to it [Music]
