goldwood's. yes a/b tested. leaves most single 18" bass reflex in the dust. there is no cubo 12 or mth 30 showdown. the mth30 was designed for a certain driver, and a few others work in it. the cubo was designed to accept a wide range of drivers, ask the designer about what drivers you plan on using and he will help you out.

i already talked to Cubo and he helped me choosing the woofer. I;m planing to use Selenium 12WS600 or Beyma 12LX60.
What woofer have u used in BR cab in the test and how many liters ?
Thanx for your answer mate ! smiley20

I think the MTH-30 will have more SPL but is bigger than the Cubo 12. So the choice is:
-SPL but bigger (MTH-30);
-Smaller but less SPL (Cubo 12).
This is a personal opinion tho.

What about directivity ? is it directive ? it's like a horn.. for example Planar wave horn or smth else...
@Giacomo have u tested side by side your MTH 30 with an 15" or 18" woofer ? If u did, what woofer was in the Bas Reflex bin ? How many liters ? thanx

I've a/b tested it with a turbosound TQ-425 (2x15") and the MTH-30 has more throw, but the turbo has more SPL in front of it. The bass extension is about the same.
Keep in mind that the mth is 450watts and the turbo is 800, and the mth is about 140liters and the turbo is about 260liters! smiley2

i;ve seen in the specification of TQ 425 ftp://ftp.turbosound.com/datasheets/tq425.pdf that it has 100 db at 1w.
U said that it was louder the Turbosound than the MTH, meaning that MTH does not have 100 Db /1w/1m ?
Later Edit: i;ve looked at the Sim and there , the subwoofer TQ has about 102 Db at 100hz, and at 130hz it has 103Db.. so it's understandeble why is louder. Anyways, it has 2 x 15" woofer, so.. a lot of air is pomped there... it;s normal to be louder. Was the difference in therms of SPL so big ? would u consider that 2 MTH 30, loaded with your RCF LF12G301 will leave behind this TQ Subwoofer from Turbosound ?

Oh, sorry, I've forgotted to say that i've not tested they at the same power .

Anyway, no, the difference was very small. Two mth can easily outperform the turbo smiley20 .

thanx for your answers. smiley2

i have tested this woofer
http://www.telecomenzi.ro/difuzor-blue- ... -2163.html
in MTH30, 2 bins. I would like to say that the SPL is way way way much bigger than a BR18" Cab ( i have tested side by side ). Even a single MTH had the SPL above the BR18".
Even with this very cheap driver, about 35-40E the SPL from 2 bins was more than u need, adleast more than i need...
For the future , i'm planing to buy Radian L12-8402 http://radian-tech.com/pdf/Radian%20L128402.pdf. I;m sure that this woofer is more apropriate for MTH and it will survive to many party's.
PS: the 18" BR is a 170L, tunned around 42hz and loaded with Paudio HP18S

can i use this cabinet for B&C 12PZ32? plz i need help, im searching for perfect cabinet. ! ! ! !
