Cubo 18 (standard) PD 1850 or 1852

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi there
Looking for some advice on the best driver for a standard cubo 18. 

I have some cubos currently loaded with PD 1852 - but I have read on various threads people suggesting the PD 1850 is a better option. 

I saw Mr Cubo had posted this on another thread:

Qts x Vas > 120, Cubo Standard
Qts x Vas = 100 - 120, Cubo Extended or Standard
Qts x Vas < 100, Cubo Extended

Taking this the PD 1852 gives me: QTS 0.33 x VAS 120.38 = 39.7254

and the PD 1850 gives me: QTS 0.24 x VAS 203.84 = 48.9

So neither of these fall within this rule of thumb. So I'm very confused. Can anyone offer any advice as to what would be the better choice. 

Thanks again

	A typical Cubo Standard driver is an American or old school European reflex driver. Beyma has quite a few, they're kinda known as a reflex orientated brand: 18LEX1600Nd Qts 0.45 x Vas 231 = 104 18G550 Qts 0.4x Vas 290 = 116 18WRS600 Qts 0.47 x Vas 354 = 166 Eminence is an American brand: Omega Pro C Qts 0.28 x Vas 639 = 179 Impero 18A = 140, Kappa 18LF = 129 Other brands that spring to mind are P-Audio and Gauss.

	Ive got CUBO standard they are loaded with PD 186 to put a 1850 0r 52 in them is a waste because of the design (Cut off freq) but ive heard the same thing. Those drivers would be fine in Extended though.
