21" driver choice

Hey all,
Browsing the options for a pair of Devastator OR ported 21" build. I am just wondering, with the options available at PE, what would be the main differences between the choices of 21" drivers (see image) Taking into account the prices ranging from $469.99 up to $749.99.

There seem to be quite a few B&C drivers to choose from. Why the price differences? Obviously the Eminence has significantly more xmax and therefore higher output, which would probably be my first choice. Thoughts? Experiences?

Out of the sub woofers listed there are three that are better suited for HT use. SAN214.50 would be the best value proposition on that list in my opinion. The 21DS115 would be ahead of it by a db or so, but if you are going to spend that kind of money, spend $150 more for the NSW. The NSW is the best for low end out of the bunch. It should be close to besting anything on that list by about 3db at 20Hz provided it receives around 2400 watts. The 21SWs would be more suited for mid bass applications. If you were building an SK they are really good for that.

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).

Having had the DS prior to the NSW I would say if you can afford the NSW than it's money well spent. More so if you are going to step on the volume, they sound cleaner and it is more apparent at higher levels.

The sound is thicker as well compared to the DS. I agree the best value out of the bunch is Lavoce, best driver is the NSW

Yeah that's the feeling I'm getting from everywhere. The NSW is just a brutally good driver. DB's review was pretty excstatic to say the least!
https://data-bass.com/#/systems/5d0b...82ae?_k=xr5wo6

And with that much excursion capability - 21mm (soft bottom too so easily more) compared to 15mm for the others, that's easily $150 worth of precious decibels there over the DS haha!

Next question then would be, how does a big ported box compare to a horn (Devastator) with that driver?

Are you talking about the same size box or just any box? Size matters....

Left side is about the same.... DEV has slightly more midbass..... you be the judge....

The DEV will have more midbass chest punch due to the higher particle velocity in a 6th order bandpass box than a standard ported box. You WILL get slammed by BOTH.... but the DEV has the greater tactile response.... both are great solutions, just depends on your goals.....

I like my bass to damn near break your ribs..... just sayin'
From 30Hz to 40Hz, the PORTED gives up 5+ Db to the DEV..... I think that is a little more than splitting hairs...

The NSW is a beast. This is pushing it to 27mm or about 2/3 gap. Ported box 20Hz tune 14.1 cuft 102 volts/2.7kw with a 20Hz 2nd order HPF.





Next is the BMD MAX pushing 103 volts/2.8kw with a 20Hz 2nd order HPF. You should see some room gain down around 20Hz so the MAX could end up more flat. Like @jujuman200 said, the front resonator will give you more TR than the ported box.






Then just to finish the brutality, run the MAX in a two way setup with a Dev Micro 1w1m.

If @Red Five ‘s BMD MAX is still too small and mild, the NSW also models VERY nicely in submax v3.

Model courtesy of @LTD02 .
Black is NSW, grey is UM18.


That driver seems to kick @$$ in pretty much every enclosure that can handle its displacement.

@Red Five

instead of the beast mode devastator cab, that driver will work better in a cab with more of a traditional horn profile.

add a third section to the hornresp model and play around with it.

you should be able to get something in this ballpark even without exceeding 2:1 compression ratio:

op, the lavoces in devastators will tear your head off. the nsw will have a bit more of a peaked response, so may require a slightly different eq. they will have a couple db more on the very low end. the b&c have been solid performers and since the 21ds115 is available in 4 ohm nominal, it will provide a couple db more output than the lavoce in the upper bass, but in a home environment, two cabs with lavoces will wreck your hearing. seriously. be careful with these subs guys.

Wow I can see the benefits of a horn configuration. Higher output over a certain frequency range. I am new to horns but I am keen to build one. Standard ported designs seem to perform more evenly over a larger frequency range, but at a lower output overall. If you could you just EQ down that big bump in the MAX, you would have quite a powerful tool there over a wide frequency range for a horn.

The un-EQ'd big drop from 60-100Hz is pretty dramatic in the MAX. The MAX and the Dev Micro would be quite a match up for sure. That Dev Micro would even it out for sure but the crossover would have to be just right with horns hey.

Overall that response looks a little more even and predictable than the Max. 10db over 20-100Hz + room gain you would get a pretty flat response!

I have had a few conversations with @kevings after he got his two GSG Devastators inside with the Lavoce SAN214.50s. Yeah hearing lose from them is a very real thing.



Having moved my Stormbreaker box up stairs. I would not go much bigger than that if I had a choice now. The Devastator v1 is 3 or 4 cuft larger than that box was. If high levels of fire power are available in smaller packages I would go with before looking at the v3 or other ridiculous horn configurations. My Mini Devs right now are north of 120lbs without subs or the hatches or all the paint...

I just messed around with the front sections of the BMD, looks pretty close, just more aggressive on the bottom corner, longer sections so resonance is a little lower. It should still be good for about 2800watts pushing 2/3 gap 20Hz 2nd order HPF. Ratio is 1.87, too hot for a 21"? If I attempt turning this into a box, you will get a few messages on calculating a few things

@AudyoVidyo @Red Five

Wanted to quickly chime in here and share my own experience with the Devastator design. I used our flatpacks and built 3 of these using the LaVoce21. With three of them in the room across the font wall, as well as an additional 21 in the near field position, there is headroom for days. The nearfield sub, even seems a bit pointless, but since it's already there, I'll let it be.

I'm running about 10db hot, and even at reference volume, amps don't exceed 50% of their available power. The system is a lot of fun, but it's just so easy to get carried away with the volume level.

The other night I was listening to some music for 20-30 minutes . It was loud, but as clean as it all sounded, I didn't realize just how loud it truly was. Next morning, I woke up with a headache and ear pain that took a few days to go away. I want to be able to enjoy movies and music for a long time, so moving forward I'm definitely respecting that volume knob more than I had in the past.

Here’s the performance table from GSG.
I’d expect the cyclops to be very similar to the full marty.

there is a difference. the devastator has an impedance peak in the mid-bass that makes it very efficient at producing mid-bass output. it is on the order of 40% or so peak. the gray line is the same driver in the same ported cab with no horn. it is only 3-4% efficient in the mid-bass. by way of comparison, a um18 in the same cab averages about than 0.5% efficiency. so in some sense, the devastator horn is 80 times more efficient at turning amp power into sound power. a devastator is not quite the same as having 80 um18 drivers from an efficiency perspective, but that kind of scales what is going on, in some sense.

there is a difference. the devastator has an impedance peak in the mid-bass that makes it very efficient at producing mid-bass output. it is on the order of 40% or so peak. the gray line is the same driver in the same ported cab with no horn. it is only 3-4% efficient in the mid-bass. by way of comparison, a um18 in the same cab averages about than 0.5% efficiency. so in some sense, the devastator horn is 80 times more efficient at turning amp power into sound power. a devastator is not quite the same as having 80 um18 drivers from an efficiency perspective, but that kind of scales what is going on, in some sense.

Wow! Thats insane!
