Cubo Kick

Bonjour,j ai une paire de monacor spa115pa ,je pensais faire 2 cubos avec,est ce compatible ?

Oui,

Not the beafiest driver though, you might wanna add plenty of dampening material in the rear chamber.

Hi Cubo,

Thanks for all your work. I'm trying to fill in a gap in my system, my sub is 100Hz at -3db and 110Hz at -10db. I want to feel the kick, and my tops don't cut it. Due to space constraints, I'm looking to build a Cubo Kick 12.

1. The Eminence Kappa Pro 15 is recommended for the Kick 15, but is the Eminence Kappa Pro 12A suitable for the Kick 12? Parameters below, link at eminence.com/products/kappa_pro_12a - limited range of drivers available in New Zealand.

Thiele & Small Parameters
Resonant Frequency (fs) 37 Hz
DC Resistance (Re) 5.46 Ω
Coil Inductance (Le) 1.22m H
Mechanical Q (Qms) 6.93
Electromagnetic Q (Qes) 0.25
Total Q (Qts) 0.24
Compliance Equivalent Volume (Vas) 121 liters / 4.27 cu.ft.
Peak Diaphragm Displacement Volume (Vd) 249 cc
Mechanical Compliance of Suspension (Cms)0.32 mm
NBL Product (BL) 17.3T-M
Diaphragm Mass Inc. Airload (MMs) 59 grams
Efficiency Bandwidth Product (EBP) 148
Maximum Linear Excursion (Xmax) 4.8 mm
Surface Area of Cone (Sd) 519.5 cm2
Maximum Mechanical Limit (Xlim) 14.8 mm

2. Realise that the Kick 12 is designed for 110Hz - 250Hz, but can it be tweaked to punch a bit lower, at 100Hz? Ideally I'd fill all the gap from 100Hz to 220Hz or so. Is blocking a port viable for the 12, as suggested in some other replies?

3. 15mm birch ply is hard to come by here in NZ, 16mm is standard or 12mm (which is far more cost effective). Aside from tweaking measurements to suit, would using 12mm ply instead of the 16mm affect sound characteristics and output?

Thank you, I appreciate your input and knowledge!

 

The Eminence Kappa Pro 12A does share the name with the Kappa Pro 15 but has worked out a little bit harder in the gym ever since. It should be able to get down to 100 Hz in singles but is pretty much guaranteed to do so in pairs, or (very close to a solid wall (2,0 pi radiation). I would first try it as is, playing with filter steepness and such, with closing of a port as a last resort.

16 mm ply is theoretically at least 2 times stiffer than 12 mm ply, if you're unsure what to use, make the heavier cabinet! That being said 12 mm will work.

Hi Cubo,

Following on from wigs' message;
Would the Eminence Delta 12 work in lieu of the Kappa 12?

Thanks

The Xmax is 2.4 mm, that's really low. The Kappa 12 is already low with 3.2 mm.

P.S. There is a solid difference between the Kappa 12 and Kappa 12 Pro (wigs).

Lucky!

Was on my way to grab a 2nd hand pair of them when I caught your message.

Will be on the lookout for anything that fits criteria.

Thanks

Great thanks - yeah I'll definitely be going for the Kappa Pro 12A, not the non-pro.

Hey Cubo!

I'm planning on building a few Cubo kicks 18. I was thinking about using the eighteensound 18LW2400. Is this a suitable driver for this cabinet?

Thanks!
