2.1 design
 

Attachment 326979

working on a design for a few months and posted some early renderings before, hopefully will start making the moulds soon. The material is carbon fibre/kevlar.

The sub will use a Seas L26ROY (not as in render), ported. The internal volume will be quite tight, around 1.3 cu.ft
The main speakers will use either Monacor sph-30x w/o dust caps or specially made Bandor 50s.
amplification is the Keiga 2.1 amp, possibly with some upgrade mods; I'll add a bluetooth module and a dac
A compromise in this design is the x/o which needs to be around 125hz or so to protect the FR drivers.

very nice, my suggestion is to throw away those deflecting elements though

really? I was going to soften the edge a little more

diffraction is inevitable anyway and it is nothing good

I am sure we can agree on that point

without those elements the idea resembles TimeDomain speakers:

and being 2.1 even more it resembles Sharp Aquos TimeDomain licensed speaker system:

I completely disagree. Without reflector you will definitely get no trebles. According to the german loudspeaker magazine HobbyHiFi a 45 degree cone-shaped reflector performs much better than a hyperbolic one.

Strassacker, Komponenten: Lautsprecher, Frequenzweichen, Bauelemente

not in my experience, one gets the HF energy via reflective ceiling

I need those trebles! :)

You will get them, no problem

looking at the german link, that design uses the W4-1337 and still achieves 84db in omni mode.. how? or is it taking both drivers into account

The speaker actually has a falling frequency response, bass at 84 dB and treble at 74 dB (anechoic measurement). But they claim the sound is balanced in the listening room...
