Hello I am Daniel from Argentina, I say to my question: Well, it while I've come from other music festivals and with my two bass reflex cabs equipped with 2 drivers and 2 woofers eminence alpha 15''bass 150w and 2 boxes of 15 '"with ARLs 250w speaker. The situation is to save enough money I want to change one the largest in Africa and buy two Peavey Low Rider was cheaper and seemed 18PRO hehe well, so I'll go to point I want to know if you do not mind if this box (cube 18) can work with my 2 18''from Peavey and thank you very much:). Greetings. PD: Data from the subwoofer.

The driver you mentioned is suitable for usage in both Cubo Standard and Cubo Extended (the latter advised). Due to llow Xmax for this driver, I would recommend keeping an eye on the excursion after putting more then 300 watts into it with the recommended high pass settings. I think you could consider it an upgrade from your current system.
Personally I always look at the weight if 2 models have similar T/S-parameters. It's not a very scientifically correct comparison but for drivers from the same series and manufacturer, that weight difference definately did go somewhere.
The Sigma and Delta pro are close in performance (Fs/Qts/Vas) but the Sigma has more weight (7.5 lbs more heat wick) due to the 3" vs 2.5" VC. Also Xmech and EBP are slightly higher. Therefore I would say the Delta Pro is best suited for small to medium power, whereas the Sigma Pro for medium power applications.
