Separate names with a comma.
These coaxials aren't built by eminence, that said the Alpha-8A has very close T/S specs to the woofer on this. For the Concentric-6 I can't...
They are just short blocks that tie the baffle and rear wall together, they do not partition off that section into separate chambers.
You don't have to disregard all posts, anything you see posted after 2018 for the MTMWW tower design will obviously be relevant as that's the last...
Yes the 2018 crossover revision for the MTMWW tower design is the current model. The build info on those first 6 posts has been kept updated with...
You can rotate the design sideways but you are correct this now means if you move horizontally you may end up in cancellation nulls between the...
In that case either way should be close enough being a couple Hz difference between the two, which is probably unnoticeable in room.
If using 4" PVC without flared ends I'd make it about 10.5" long.
Yeah if you want all three to match perfectly then you can do that, I had a post a few pages back talking about that change:...
Sorry for the delay, here is a 3d model of the cabinet with all pertinent dimensions: [ATTACH] [ATTACH] [ATTACH] [ATTACH]
Yes I still have bare PCBs and can cut baffles as well.
Yes still have 8 of the drivers.
I don't envision any major issues from those changes.
Hi Dane, The baffle design I posted here fits these flat packs from Parts Express if you wanted to go that route? They would certainly work...
Crossover Info: Like I said above I retested the design and made some slight adjustments to the crossover largely focused on improving midrange...
Info: Buried in the DIYSG warehouse were several dozen new Concentric-8 drivers, Erich and I dug them out on my recent visit and I've been slowly...
Yeah that looks perfectly fine, though at the frequencies the woofer is playing being partially blocked by the frame will do very little anyway....
No changes on the MTM. That was the first design I did with the updated measurement rig, the more detailed measurements from that rig is what...
You can increase the vertical distance between them several inches without issue, a grill over the woofer is also not a problem.
I'm having trouble trying to figure out what exactly you want to do. Are you talking about a horizontal offset between the waveguide center and...
The grills do effect sound quality from diffraction and some HF loss but only to a minor degree. They can cover port holes provided there is...
