I made a picture frame style surround and I bought the grille cloth from eBay about 3 years ago I'm just waiting for my piping to turn up to finish it off

I've kept my options open on the second one

The first one got a grille today

Hi De Hi Second cab took shape today Removable baffle this time Fun! 😁

True - there's not much to it is there?

If only we could develop this into a tiny flatpack kit You can get 3 cabs from a sheet. I will have to see if there are any CNC wood machinists near me (Norfolk)

long thread warning.. Hello All First outing with the scrap ply cab last night I loaded the car and looked at this little black box in the corner of my boot and though “I don’t think I’m going to have enough grunt tonight” I play in a Glam band with 2 excellent guitarists who really like to noodle and a solid drummer The cab was plonked on the floor (in landscape mode if that makes sense) and hooked up to my TC BH550. I tilted the cab back very slightly with a high tech lump of wood No pedals – just a lead and a classic vibe precision. A tad of compression on the amp. Low bass turned down a bit to avoid pummelling the pulse 10. Mids and top enhanced a tad I tried it out whilst others were setting up and thought “Blimey - I might just get away with this” Began rehearsing and I got a little lost in the mix. Turned up a little between songs and I was there. I sat right in the mix with a smile on my face. I usually use 2 x 50L cabs with Beyma SM212’s. We rehearse in a steel stockholders, so it’s quite ringy and boomy. The 212’s used to sound very muddy (but sound great outdoors or in a dead room). I think the band used to play louder because of this boom With the new cab, we played a bit quieter (lovely) and my tone was right there. Highs were clear without being obnoxious. Bass was enough for it not to appear like I was using a practice amp Compliments during the break along the lines of “I can’t believe that little thing” The Pulse 10 is quite a little powerhouse. I was dubious as to whether it’d cut the mustard, but I’m pleased to say it does Remember this is a 1 x 10” 200 watt small enclosure so it’s not going to shake your fillings out. It will be easy to transport, make you grin when you look at it and it’ll hold it’s own with a band who aren’t prone to inducing tinnitus So – 1 cab for a rehearsal? For me, yes indeed. Would 1 cab suffice for a gig? Hmmm. Jury is out on that one. Tiny pub? Yeah. 100+ room?…. I’d be wanting a bit more grunt for peace of mind BUT – Given I now have the ply, speaker and hardware for a second one, I think we know where this is going I may make the second with a removable baffle, so I can try the 212’s in a smaller enclosure. Top hats to be fitted too so I have an emergency PA system. Thanks once again to the people behind this thread/design for a great little build I would say to anyone thinking of having a go to just get on with it! There’s loads of helpful people on here. Bring on the next design 😉 Jon

the horn and hf driver were purchased this morning (along with lots of other goodies I don't really need) i may even fit tophats.... Ideal little PA for sordid parties in my s*x dungeon 😋

I got all excited when I modelled it - thought I may get even more performance from the little box of goodness, but i've calmed down now 😝

Didn't want to come across as negative when I mentioned that and thank you for the ace explanation (as always) I'm certainly learning more about design for sure The little cab is going to get a test tomorrow night - I already know that my fellow band mates will scoff at it's tiny..ness Tweeterless (or tweetered but with an on/off switch) cab to follow. Will commence this weekend once i've collected the scrap ply from my friend Be good to see a few more attempts popping up on here Jon (ps - is there any way of changing username? carnabies were my old band and i'd like to change it)

I must confess I'm a bit of a Beyma fan This evening, I've been comparing the pulse 10 (£60 free carriage) to the 10CMV2 (£53 £7.93 carriage) I put them both into winisd Cab size (nett) 30L Tuned to 55hz 1 x 10cm dia port The CMV2 looks rather tidy Am I missing something? Doesn't seem to exceed xmax @ 250 watts (down to about 45hz) Equals or betters the pulse throughout the response curve Is it worth investigating? Or am I getting excited and not spotting a potential issue? Voice coil is 0.5" smaller than the pulse, yet rated to 50 watts more?? I'm assuming it'd need a re-think on the crossover side of things enough to notice??? Could any clever beans offer me any advice? Even if it's shut up and finish your cab off 😁

I spent all last night listening to music through it It was a night well spent Rehearsal on Thursday, so it'll get a good test in it's intended environment I'm leaning towards a cloth grille

Wallop! Not quite tuffcab paint - Rustin's step paint from Toolstation Rough finish, but it'll do I did the good old rice test this morning and got 52hz. I'm guessing i need to add a few more millimetres to my port length - i'll give it a go Not sure what to do grille wise. I have some cloth, but I quite fancy some perforated aluminium sheet. I've installed the tweeter so that the 90 degree dispersion is in the vertical plane. Feet on 2 sides so I can use it in both planes My little ipod into my BH800 and through this tiny cab is really, really nice. Nicely balanced. Added a little bottom end via the EQ makes it even better Second, tweeterless cab is on the cards now Weight - My scales (which always seem to lie to me when I get on) say 11.5kg I've already lined up some more scrap 15mm ply for the second one 😁 Grille to go! 👍

Hello Again! Well.... the teeny tiny cab is together and has been tested It's definitely easy build I haven't applied any finish to the cab or a grille as this was a test version (although i'm falling in love already) I made the crossover on a piece of thin ply. It really is a compact cab. I used araldite to glue the port extension on and then stretched some gaffa round it nice and tight for support One point I would bring up (and I could be talking rubbish here).... The port ends closer to the rear wall than I would have expected to be ideal. My thoughts were that you needed at least the diameter of the port. Any thoughts on this chaps? (port length 170mm) Or does it not matter? I coupled up my BH800 and played some tunes through it via an ipod. I was very pleasantly surprised. Nicely balanced with neutral equalisation and with a good dispersion of higher frequencies. My better half said "that sounds nice" - praise indeed. I've played my precision through it for a few minutes and its great! Not bottom heavy, but then I didn't really expect it to be. BUT It's clear, punchy and responds very well to EQ changes. Would I gig with it? Probably not unless it was a small room.... Would I gig with it plus another cab (minus the tweeter section) yes definitely! Its probably a bit unfair to do a review after such a short time, but I promised myself that i'd contribute to this project as well as gain from it. I'll report back once i've done a rehearsal with it Anyone can make this cab. The joy of hearing your creation come to life is soooo worth it! I am v tempted to knock some 12mm versions together (although the V3 basschat design is calling me) Thank you to all who are involved in this wonderful little design Pics attached - drill shown for scale 😊 Jon

this was made of 15mm Phill as it was donated to the cause by a friend (so i guess that'll help a bit) to be honest - i'm not proud of the build. It's not as accurate as I would normally make an cab to, but my intention was to use it as a test and then build from 12mm But... as usual... the desire to get it looking nice has taken over and i've spent much longer than I had planned on it I've got a cut list together for the 12mm ply. Looks like you can get three complete cabs and one spare of each panel from an 8' x 4'

I have braced the baffle but not the rear panel and strut between I will do that tomorrow

It's getting there 😊

Most excellent... Thank you for that Glad to know I wasn't going mad You did mention conservative xmax figures in a message to me Game on!

Me again.... You'll all be sick of me soon I've put the necessaries into winisd for the pulse 10 in the lockdown cab I've used 30 litres and 50hz as the tune My question is - am I doing something wrong? I've got the port length as 23.46cm @ 100mm dia If I put 200w into this, it appears that i'm exceeding x max I'm not questioning the knowledge of you guys... i'm simply wondering what i'm doing wrong To get the port length to correlate with your findings, i'm having to tune to 55hz. Xmax is still exceeded I'll build to your specs, but just wanted to see what I was doing wrong. Hopefully i'll get my scrapwood challenge together this coming weekend Cheers!

Mine began to take shape today 15mm scrap ply from a friend, so I've had to tweak dims a bit to keep internal volume correct. If it's a winner, then i'll probably make a couple from 12mm Will probably end up carpeting it and fitting an aluminium grille About 4 hours into it so far Minimal tools - speaker hole cut with router on an arm pinned to the centre of the circle. Will also use router to radius the edges of the cabinet before carpeting Horn and port holes cut with a jigsaw with a normal blade. Take your time and you'll be fine! All panels cut from the best bits of the scrap offcuts with a worx mini circular saw. Did the job a treat. All panels and battens PVA glued (lots of) and pinned in place with a cheap silverline air powered brad nailer. They only hold the pieces in place whilst the glue dries Easy! Small! Fun! Measure twice (or more if you fancy) and cut once. Have a go! Thanks for all the shared information on here. Jon

thank you for that phil 👍

will it lower the crossover point at all Stevie?

Me again..... Quick question I'd like to use 2 of these with a 300W @ 4 ohm Shuttle 3.0 The bottom one with the hf section switched off 2 cabs daisy chained together would give me a load of 4ohms at my amp Would this be an issue with regards to the performance of the crossover in the upper cab? I assume it would lower the crossover point???? Is a two cab setup viable with the simple crossover? Cheers
