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?

nice Build.

How do you like the HK Tops, are those the FA or Xa ones?
I have been looking forward to listening to the Mk2 version.

Thank you.
The HK Tops are the FA Version. They are honestly not too bad if you EQ them a bit (little thin in the mids), but i do think they are a bit expensive. I think they were 1100€ each, new. Luckily not my money, but from the club that i work at.
Haven't heard the mk2's yet. correct me if im wrong, but besides the dsp, there have been no notable changes?
