Spirit of the age? OR, you look at things more than you typically use them. I will look at these speakers more than I will actually listen to them, so looks are fairly important. Also, if something is worth doing, why not do it well?
I'll be following this build with interest. I'm looking to get something for my living room that feeds into our kitchen - so I'll wait for your final evaluation. Thanks!
My vote is for the carbon fiber nylon because of its matt finish and lack of layer lines. I'd like to see the vertical tubes wrapped in a nice wood veneer. Don't forget to throw in some custom machined metal components to really give it that high end look. Excited to see this project.
I think I'm going to go with NylonX. I actually already reached out to Matterhackers and they will be sponsoring this project going forward ;-) I thought about wood veneer, but it doesn't look right to have it in a column like that. Nowhere in nature would you see grain wrapped around a cylinder. I mocked it up in Solidworks and it looked very strange.
I own a pair of Meridian M6 speakers that uses the same mid-bass and has a somehow similar shape for the mid-bass. It sounds great, the bass is really good.
OMG yes. I actually have some big drivers with vented pole pieces. My goal was to use them for fan subwoofers (a big-ass fan, but with variable pitch blades like a helicopter that's connected to the voice coil). Too many projects!
I don't know if you are aware of this. The 125ASX2 modules are a filter-less design, that may not work so well/absolute optimally on every speaker, due to the high PWM signal coming out of the modules.
I've tested them quite a bit and they sound pretty decent with these drivers. I've used them before as well on other speakers. They were a good budget option, as I didn't want to go too crazy with the electronics on this project.
@@RobertCowanDIYFair. Have you ever for the fun of it, looked at the output of these modules on a oscilloscope. It looks so strange not seeing a clean "analog" output.
@@Mr_Wh1 Ha. I haven't! But I did own a pair of amplifiers based on them and they did sound quite good. When speaker shopping, we brought them along and tested a lot of speakers with them (and against other amps). They can sound quite good with the right speakers. EDIT: Keep in mind though, this will be an audio system for a summer cabin. They aren't meant to be an 'end-game' speaker setup, they're mostly for fun and to look interesting. If I were to go all-out with them, I would most likely pick a different amplifier.
@@RobertCowanDIY I am not saying anything negative about the modules, I own some myself, it was just to point out that the module is dependent on a cross-over filter or large inductance to filter the output.
@@Mr_Wh1 I read somewhere that these amps need some kind of buffer or something but never understood exactly what is it. Can you elaborate more about that or point to some link. Tks
For real. I was REALLY surprised. They do bottom out if you try to go too loud, but in a smaller room (which is where they'll end up), it's quite good.
10:41 That sounds pretty dang good through my headphones without any sort of correction. Nice! I may have skipped over any sort of "Final Cost" you're at so far... care to share a $$ figure?
They do sound quite good in person. They need a bit of tuning and a smaller room. My main living room is quite large and open to the whole upstairs, and the shop is around 850 square feet, so both are relatively large spaces. My total budget, all in, is going to be around $1500. I'll talk about that in the next upcoming videos. They're not cheap by any means, but you get a pretty high quality setup for that money, and that includes amplifiers, DSP, etc. Just connect to a digital source and you're done.
Nope? Did you comment on something that's not showing up? Sometimes YT will automatically 'hold' comments for review if they have links. But I don't delete comments I don't like, I just write nasty replies.

So much energy expended on appearance. 40 years ago 30 seconds would have spent talking about aesthetics. Spirit of the age.

They're worth the money, but they're much more of a 'critical listening' speaker.

@@RobertCowanDIY I was going to recommend wrapping in CF wrap (The PVC) but this seems much nicer of a design.
Looks like an interesting design. Looking forward to see your spin on it.
I have the second video done and the project is nearing completion. I think you'll like the end result.
Interesting design is to search " LXsirius - superslim"...

I've always liked Meridian. The DSP8000 is what got me into high-end audio!
When can we expect the Cowan Technologies rotary subwoofer?
My lft-iii speakers would slam with a rotary sub 🤣
OMG yes. I actually have some big drivers with vented pole pieces. My goal was to use them for fan subwoofers (a big-ass fan, but with variable pitch blades like a helicopter that's connected to the voice coil). Too many projects!
now there is a blast from the past... I remember seeing the rotary sub about 13 years ago and then nothing...

more bass response than expected

Will you sell the 3D printed parts I’ll pay you to make me some
No, sorry. There are plenty of 3d printing services out there though. And it's always a good time to get into 3d printing.
How far is the center of the top driver from the bass membrane in the tube? it seems to me that it is too high.
It's the correct distance ;-)
@@RobertCowanDIY Yes, now I know, I reconstructed your solidworks drawing:)
Unreal, are you Robert deleting comments ?

No woodworking skills needed.
Nope, just 3d printing and more advanced skills ;-)
More like building a container, the speaker is already built.
Congratulations on being "that guy".
