Sealed 2 way with SB26ADC+SB23NBAC

[Jonazkur]

Here is my latest sb acoustics speakers that i made. They use sb26adc tweeter and sb23nbac bass driver in 25L sealed box. Here is some pics and data.

Great result and beautifully made! How many X-over parts?

Excellent work on the cabinets, particularly the waveguide. Care to describe your process? They turned out incredible.

BTW, I have used those same SB drivers to great effect.

You can ask details, its hard to describe the whole process . That SB23NBAC works great in that sealed box and reaches to 30hz in my room. Too bad that its distortion performance isnt ideal and it has high H3 in midrange, but i find it hard to hear still with music even when im comparing it to my speakers with purifi PTT8 drivers. Only when pushed really loud then purifi wins in clarity.

Very sensible and nice result! What is the sound power DI slope? Around 1.4 db/oct?

I dont remember i must check in vituixcad. I mostly usually just look at polar heatmaps.

Is it the 4-ohm or 8-ohm NBAC you are using?

Awesome results and build. Where did the WG come from, your own design? Also, is it printed or machined? Other than that little blip around 1200hz the DI looks perfect and the horizontals are really crisp.

Its ATH Tritonia S horn and 3d printed. These speakers were actually just for testing how the horn works but they turned out pretty good and sound nice with subwoofers. Also they were pretty cheap to make bcouse i got the woofers also from sale 69€ a piece

Here is distortion at 90db 1m

If you could give a breakdown of the crossover components, would be cool
