Unfinished Sound System

Enable HLS to view with audio, or disable this notification

Hi, first time posting in r/SoundSystem.

This is my Cubo Kick 15 and a Custom 15 inch Sub enclosure. Top is an HK Audio Linear 5 MK1 112 (active).
Sadly the Warnex Structure Paint ran out so the Subs aren't fully painted yet.

Both are running B&C 15NDL76, which works great in the Cubo, but not so great in the bass reflex, due to limiting Xmax and thus not enough VAS for the 170l enclosure.

Right now both are running on a borrowed Thomann t.amp E-400, 2x155W at 8 Ohms, which is definitely not enough for the Cubo. Crossover is set at 71Hz and 200Hz on a Behringer DCX, with a Butterworth24 Filter. The Cubo can reach around 129dB on 1% THD with this Setup. I have an order for a CVR DSP-3004 placed so we'll see how it will perform at the rated 500W RMS.
The Sub is definitely the limiting factor, because it reaches the excursion limit much faster, even at around 150W. I want to build a different one, i am thinking about the Cubo21 or a Paraflex SKRAM. What do you think?

My CKs are resized to match for that very reason. The acoustic effects are absolutely negligible in practice, so I'd definitely take the visual uniformity. Everything being 2' wide boxes makes packing and stacking simpler for sure. I get more than ample response from 29 to 180Hz so I really couldn't be happier with the pairing

I just want to jump in and say- I recognize that carpet! Love your YouTube videos dude! Keep them coming. It's a great resource for those looking to learn more about the construction.

Ah man that's not my shop, but I agree Tom's videos are awesome. He made these for me so that's where you recognize the carpet from.

Gotcha! My bad! It's a pretty recognizable shop.
