Horn Speaker - DIY Compact Mass Loaded Horn Speakers Mark Audio Full range Drivers.

[@mndlessdrwer]

That rosewood veneer is absolutely gorgeous. Not sure I could have resisted getting their gold or dark grey drivers just for the aesthetic with that beautiful veneer.

[@DIY-AUDIO]

Thanks, the chn-50 are only in silver though!!

[@fonkenful]

I generally tended towards the copper/gold drivers myself. They look absolutely stunning in Sapele, dark American Walnut and Rosewood. The natural paper coned CHP70s are wonderfully suited to clear coat finishes on either Baltic Birch plywood, or Maple veneer. If you’ve not already availed yourself of the opportunity, I’d highly recommend trying to get your ears on a pair of the MAOPs. The cone treatment is expensive and has a high failure rate, so they are not a cheap driver, but definitely not snake oil.

[@chevyimp5857]

Cool build... Thanks for taking the time.. where do you buy your veneer ?

[@billn2647]

Great build! I got concerned however when I saw how you cut the panels down on the table saw in the beginning. I would highly recommend using push sticks and not wearing gloves near high-RPM rotating machines as it is a safety risk of being dragged along in with them at worst case. Push sticks can be replaced, not so much your fingers/hand!

[@DIY-AUDIO]

Cheers Bill!!

My mom lost one of her fingers when she used the rotary saw while wearing gloves.

[@rigorhead01]

Love the rosewood veneer! When trimming the veneer with the router, If you have have problems with slight splintering the end grain, try a sharp chisel. When you get the angle just right it'll slice through the veneer leaving a perfect edge. Try it, you won't believe how well it works and how easy it is to do! 🤣

[@peterjmcgee4680]

You are a very smart man not very many people know to do that with the super glue to keep the particle board from deteriorating where the speakers are being held down very good Trick Use that many times when I build my own speakers and when I built speakers for customer Done not a lot on custom jobs Makes the cabinet last a lot longer from the vibration especially when you have people that love to turn the volume up

[@DIY-AUDIO]

Thanks, yes it was trial and error that I now use the super glue. Especially good on the thinner MDF but now use it on all the builds.

[@alangroskreutz235]

@@DIY-AUDIO I'll be using that trick on all my subsequent builds. Thanks. Veneer looks marvelous.

[@ckmoore101]

What I have always done, is to drive the screws in, than remove. Then I put CA glue into the screw hole, and immediately drive screw in, and then back out again. That coats the inside of the screwhole walls with the ca glue, vastly improving their gripping strength. Never had a single tear out after doing that in all of my speaker builds.

[@ScottGrammer]

Gorgeous. I really like small full-range speakers. I wouldn't call these "horns," though. More like a resistively-damped transmission line. Subscribed.

Muy interesante no había visto nada igual muchas gracias por compartir tu trabajo

[@DIY-AUDIO]

Hi, sorry I can't translate in order to reply

[@Blue-green-f2t]

Something most people don't know; Don't twist mult strand wire when using crimp connectors. And you should never solder or tin wires especially before crimping/camping, seen plenty of these fail because of it.

[@DIY-AUDIO]

Everyday a school day!! 👍

[@Blue-green-f2t]

@@DIY-AUDIO The crimp or clamp, when applied correctly on bare copper, actually bunches up the strands and deforms the copper, which is malleable, and compresses it to form a secure and often quite well sealed connection. This can't happen with a tinned wire as the solder is hard, uneven and won't deform to the same extent creating hot spots on the crimp/clamp. The solder also has voids in it which means when it heats up some of the voids will evacuate and the blob of solder can reduce in size, especially when under pressure. The wire then becomes loose, if not already loose. Twisting the wire and crimping/clamping will prevent it bunching and deforming as it should, this is why we should use ferrules on screw connectors with multi strand wires and multiple conductors. Clearly on a car, after ten years living in the damp uk weather a crimp will corrode and fail. Adding heat shrink, especially adhesive lined is a good idea as it will add another level of sealing and give support. A good crimp however should grip the insulation of the wire providing strain relief. If you're going to solder use solder bucket connectors which will have an additional strain relief on the connector body. Finally copper work hardens i.e. it becomes hard and brittle as it is bent, moved, hit and subjected to vibrations. Heat cycling copper anneals it and it becomes more ductile, this one reason why over tightening screw clamps causes them to work loose, especially when multiple conductors are inserted. Ultimately, use the correct wire size and connection combination. T.E. Connectivity and other manufacturers/suppliers have tutorial videos for this on KZbin. There is also documentation on their website. I didn't intend to write that much but once I started it kind of flowed. Hope this helps you and others understand what is happening and helps everyone produce high quality and more reliable work.

[@pauldecort]

Cyburg Needle, the most widely built ML-TQWT in Germany and ideally suited for Markaudio drivers,, uses no damping material in the back part of the speaker, so you probably frustrated the workings of an ML-TQWT

[@DIY-AUDIO]

A bit of a likeness. I'm amazed when listening to classical music the depth of sound from this build and thr fact its only 3" 7watt drivers

[@doglovemimijumable]

Great built! But I have to notice this in not back load horn, horn requires a mouth not a sealed end, this is TQWT.

[@DIY-AUDIO]

Look carefully, it's compact and it isn't sealed!! 😁

[@doglovemimijumable]

I found it! 😂 Then this is Mass load transmission line - Bass reflex in my category, produce deeper bass than normal BR box with better quality, the definition among horn, TQWT, TL are blur but I think they all share the same theory, I just build a cab that goes wayyyyy too deep down to 20Hz@-3dB in near field testing with 6.5” bass driver, maybe not usable but it really can shake！ I’m a fan of Markaudio driver too 👍

[@leoparddiy]

Omg that's so good😯, I like the wood motif... Gd job👏

[@nickk6109]

Interesting build - I have a pair of CH50s in the small build, I'm missing some depth I feel (I have Castle Harlechs which are a dual loaded 1/4 wave with a tweeter). The smaller cabs just miss a bit of bass. I have some 9 ply baltic birch that I could make a pair with, alternatively I'll make a practice guitar amp.

Hi, didn't have one. There is one on the latest Build!

[@George10767]

This is a very well made *BASE REFLEX* speaker. It works on the *HELMHOLTZ RESONATOR* principle. But it is not a "horn" speaker in any way or it would resemble a Suzerphone with a very large flared trumpet-like output orifice. (They used to use "horn" speakers on mechanical phonographs, but to work well they need to be prohibitively large).

[@DIY-AUDIO]

Cheers George, as the video says, I'm following the build on the Markaudio website.

[@pauldecort]

It' certainly not a bass reflex and also not a horn but a Mass Loaded Tapered Quarter Wave Tube (ML-TQWT)

[@DIY-AUDIO]

It's a MDF sealer.

[@a-matics1831]

@@DIY-AUDIO okey, hear about this first time. I use plywood allmost time. I have one question more, did you ever use some filler before veneering, filling some deep scrats/ holes, i makes 3 test veneering yesterday by using car 2k filler, snicker wood filler. Test with car filler going wrong totally cause pva cant glue together with 2k fillers, test with wood filler(snicker) glued together, but the contact really weak/ pva glued on filler but when you try remove it, its come loose with filler. So the wood filler is shit too. Now im using router to cut out a bit larger holes and fill them with pice of mdf and a little smaller defects with pva and wood dust or something, its work better. Mybee i dont use right water based fillers but allmost what i found in estonian markets didnt work when you want to finnish speaker cabinets using veneer.

[@DIY-AUDIO]

Cheers Jon, never had an issue, a good quality glue and it isn't going anywhere!! . More likely to use pins though if I was butting all the joints but cutting and gluing all the joints at 45 degrees on mdf gives an incredibly strong joint with just the glue.

[@alfaholic3]

Nice build. I never really liked the woodworking side of speaker building but this is really fun to watch. If you dont mind me asking, in your opinion which is the best affordable 4 inch FR driver? I am currently building a Bluetooth stereo speaker and looking for a good 4 inch FR or coaxial speaker to use for the project.

[@DIY-AUDIO]

Thanks, I prefer the finishing as it's what can make something individual. Basically though I don't have the patience to work out Crossovers hence the FR drivers. Personally the Markaudio Pluvia 7.2HD is great for the money once run in. But, depending on the money you have I'm sure there are better as I'm sure some would argue!! but I'm not made of money so all drivers I've used on my builds are between £10- £50.

[@alfaholic3]

@@DIY-AUDIO haha. I always say don’t have the patience for woodworking but it’s an important part of the build so I am really trying to get better at it. Thanks for your recommendation. I am building it as a job site radio for my father and have never used FR drivers before but I must admit these sound much better than I expected. I’ll look into those drivers as they seem right within my budget.

[@DIY-AUDIO]

@@alfaholic3 if it for a job site radio and its going to get battered and thrown around, I'd use cheaper drivers if I were you and design some cages to protect them. At least if they do get damaged it will be really cheap to replace them. I built a cheap boombox for my daughter (build is on the channel) and they are only about £13GBP each!!

Also why you didn't leave one side panel un-glued for adjusting the staffing ? My experience teaches me not to involve with something I don't like. Quick crafting with a beautiful finish
