We have designs for 21s, 18s and 15s , 12s? I have plenty of jbl's brought from bestbuys thanksgiving sale and a couple of infinity 1262's if I can make better use of them in a small enclosures.
I had to settle with ported boxed for my lavoces 21s due to available space especially in depth, couldn't go beyond 20". I may squeeze in mini with 24" but sure they can't be near with just ported lavoces 21s. But sure I will build the minis or mbm 30 to utilize my pa460s on hand for study room.

I looked into a full range Dev for 15"s and it is down about 7db at 20Hz vs the 18"s, which is down about 4db at 20Hz from the 21"s. The PA460s in the Minis will have a lot more mid bass than the VBSS, if you do not mind the added complexity of the enclosure.

You can always turn it down, but you can only turn it up so much (before you run out of power, excursion or structural integrity).

I haven't simmed it, but looking at the specs yeah it would do just fine. The mini would most likely be the most ideal. The SAF is not expected in till 11/26 now

Narrow Mini Devastator 18"

Another addition to the Devastator family the Narrow Mini Devastator has been designed to work in @Audiophile75's space The tune comes out to a calculated 20Hz and the length of the front resonator is very close to that of the standard Mini Devastator, just a little was taken off for added port height. Note that the panel overlap is not standard, it is close to the Micro Devastator. Sim is calculated using the SAF184.03, port velocity is down slightly.



Note panel alignment






SPL graph about 1300 watts 20Hz 2nd order HPF

Thank you @redfive for working on this for me.
So, what's cool about this design besides the 21” width? Well for starters this design was also though of for the pa460 as I have two just laying around with the intentions to upgrade at a later day. As discussed by us the pa460 will take 300w at max excursion which will be at a 10db loss at 20hz compared to the SAF184.03 at 1300w. So, when do the SAF’s go on sale? Lol.
I guess I know what at I’m doing this weekend.

I did a quick edit, the PA460 chart is in the attachments. Looking forward to seeing the build

Mini Devastator 21" Version

This is a slightly beefed up version of the Mini for 21" subs, such as the SAN214.50 This gives the sub a little more breathing room than the standard Mini. The simulation is done with 91 volts/1600 watts going into the Lavoce SAN214.50 with the standard inductance model. A 20Hz 2nd order HPF is active. Port velocity is under Eminence recommendation of 34m/s and considering the output is over 117db when it is at the highest point I doubt that is what you will be hearing 91 volts is the expected power output of a NX3000 bridged at 20Hz for longer than just a fraction of a second. The point of resonance is moved up a little vs the v1 since quarter wave resonator is shorter.

It is under the attachments for the MBM. You can see 1w1m sensitivity is pretty close. Excursion should be a little less on the MBM with the higher tune.
