I presume that Weight to be in birch ply

I calculated in MDF, as I can only see this beast used in installs

the P-audio SD21EL monsters subs, we designed, were about 180Kg each (and the outer dimensions were similar)

It will be less in weight than Lab Sub and with more convenient driver. Exactly what i needed.

PD1850 will give a bit more aggressive "dryer" sound than other two noted in post .. all sim. prediction.

Hi,
 
V18-1000 is very close to PD1850. Will fit (even grooves on panels "J" & "B" are not required if panels and speaker cutout is positioned precse as required) ..but you will lose some LF extencion (under35Hz) in comparison with V18-1200 or L18P300.
 
Best wishes,

Hi again Stipe, you may have seen or read on some threads about a driver called the TurboMax 1200 made by RMJ Loudspeakers ?
 
Anyway, the magnet is not as big as the PD's or the V18's but the depth of the driver is approximately 8.5 inches.
 
What do think about this driver fitting in the chamber of your Hog scoop ?
 
From the brief specs below, do think it would be an ideal choice for the HOG ?
 
depth is 8.25 inches not including front gasket, res. is 32Hz which can be lower if required (26Hz)

@madboy - Speaker unit mounted in Hog Scoop becomes unloaded at freq. below 25Hz so I recommend setting high pass filter (subsonic filter) at 25-30 Hz to prevent unit damage and relieve some power for upper range.

 

@Tekasis - I can't find TSP-s for TurboMax 1200 unit. If magnet structure is same or smaller diameter than P.audio SD18 it may fit even without routed grooves... but I can't tell you for sure without exact side-view dimensions.

 

Best wishes,    

           Stipe

There are many crossovers that come with high pass filters so you may already have one!

Just 2 Questions
 
1.  Why is the chamber do compact / tight, similar to Microscoops, what advantages / disadvantages does this have with sound ?
 
2. is there a function ofthe baffle being at an angle ?
 
 
Thanks
