The MT130 or MT121 become suitable i.m.o. if you're ending up with building at least 4 x Cubo 18 (total). If you're using 1 or 2 Cubo's, a simple reflex cabinet is a better choice, as it offers wider dispersion and will easily drop down to 80 Hz.

Hello Cubo. My friend and I are having a project and the plan is building 4x of the Cubo 18. High Spl in the lower range and good sound quality is why we have chosen this build. We Browsed through some drivers and we landed on the RCF LF18G401. How do you think these drivers will fare in this build?
On paper they look like a pretty good match, but I'd like your opinion on our choice.

Here is the T/S Parameters:


Resonance frequency

Fs 33 Hz

Re 4.8 Ohm

Qms 7.6

Qes 0.30

Qts 0.29

BL 24.6 T · m

Mms 182 gr

Vas 268 liters

Sd 0.122 m2

Xmax 8.5 mm

Le1K 2.4 mH

Eff 3.09 %






I laid the spec sheet file here in addition if you need to see something else about the driver

Those are goood drivers (third o intended). They will also work in Cubo Sub for that lowest oemmpph. In Cubo 18 Extended they'll offer maximum SPL, whilst still being a one-man-lift.

Thanks for the reply!
Also one more thing. How is it by stacking these 2 and 2? or even 4 by 4. Is there anything to gain?
In the case which it is something to gain then how is the best way to stack them in order to get the most advantage of it?

There is subtile differences between different stacking configurations, some might pronounce the ~100 -120 Hz 'kick'-region, others have slightly more 40-50 Hz output.. Stacking flattens response but can also create peaks. Personally I prefer to place these differences under the heading 'personal preferences'. Placing the horn mouth's together is always a good idea though.

Hey Cubo,
Plans have changed since I last posted, Fane turned out to be a dead end in my area. I currently have a B&C 18TBW100 sitting in a box, I know that some of the other B&C 18's have been modelled but I can't find anything on this driver.

Any thoughts?

Thanks

@Rotebass: The 18TBW100 is best used in Cubo 18 Extended, with the magnet inside the horn. Parameter-wise it's a true subwoofer driver though, so it would have it's place in Cubo Sub as well.

@Thohaug: Daring colour, looks good. Are you gonna use rubber feet?

Best regards

Cubo
