- I play it all. Whatever works for the gig. Q+
Is there damping inside the cab?
I tend to prefer a nice dead cab. so i don't here that overhang of notes that were played... I had a pair of Meyers years ago. If you tapped on the speaker CONE it was dead as a wet rag.. and it reproduced my bass GREAT.. Some cabs , when you tap on the cone the cab rings like a floor tom.. And to me those cabs may seem louder BUT they have a midrange that is murky and blurred.. In my opinion. I dont know why. Just my observations

I tend to think damping in a sealed cab is more critical than a ported cab, though that can be pretty important too
We were very selective about the type of batting used and experimented with different layers on different walls, etc.
Of course, what we preferred is stupid expensive!

Don't tell me you tried stuffing the whole cab with "angel" hair
Actually, unicorn whiskers. Crazy expensive!
No, I'm not attempting to pedal any snake oil here. I'm just saying the batting is crucial in a sealed cab of this nature and we did a little experimenting to find the right solution for these cabs

I was pretty "serious"
with the "angel" hair and it IS expensive, it seems to have some really good damping propertiesMundorf Twaron Angel Hair Wadding | Hifi Collective
Btw. I don't know about the snake-oil-coefficient on this product but here's some info on the stuff Link Removed

Aha! Sorry, it's late here in the States and I was just trying to make a joke. I am aware of angel hair for batting, but we went with something else
I just don't ever want to come off like some of those companies that try to convince folks they reinvented the wheel and put magic into their products. Good designs do involve R&D, experimentation and common sense. We've done those things and we're pleased with the results. Some other folks might agree with us. I just can't take the snake oil treatment and want to make sure we are clear that we're not in the business of selling it!

I know, me too
Sleep well
Managed to sleep a whopping 3 hours...always have trouble sleeping this time of year.
On the plus side, I'm having a meeting with a buddy who is having a CNC machine installed this week. We're gonna try to come up with some cool, custom grill designs
Sorry to resurrect this three week old post: How would this cab compare to a Berg NV115? In term of tone, sesitivity/effeciency? Cost?

I've never used an NV115, but I do like the NV610 and NV412. Jonathan Reiner (who did all the 'heavy lifting' design work on the 1882) has used an NV115, which in part led him to doing his own sealed 15/8 design. The 1822 is beefier sounding than either, according to him. Whether that's a good or bad thing is up to personal taste. I like a fairly thick low end.
As for sensitivity the Berg is 96db and the 1822 is 99db. The 18 has much higher Vd as well. As for price, you can PM me if you like. I don't remember what the NV115 sold for, but if memory serves, the 1822 is a bit more expensive.
For me and Jonathan, the design goal was to get a sealed design with the sound of a big cab in the most compact cab possible. The 1822 works for me as a standalone cab. It's certainly not tiny, but it's not nearly as big as most sealed designs that I think work as well. As always YMMV.
Hope that helps!

The big challenge with a sealed cab, especially one with a single driver, is getting enough output so that it is suitable as a standalone. The 1822 has the sensitivity (99dB), power handing (500 watts), and displacement to pull it off for a lot of applications. IME, anything less isn't going to be enough for most folks and would likely require a second cab. Top end is good up into the 10-12k range, -3dB is in the low 60's.

I owned the Berg NV115 for awhile: nice compact cab and I liked it a lot, but I liked JGR's sealed 15/8 cabs even better when I did a direct A/B. I have not heard the 1822 in person, but JGR was involved in its design, and the YouTube demos are proof enough to me that I would like it much better than the NV115.
Well stated. It seems to take an 18" sealed cab to get the output and low end of a 15" ported cab but the ported design doesn't deliver the tight thump that sealed cab brings. A -3dB in the low 60's is excellent for a sealed cab. This 1822 is the best single driver sealed design I've seen.
I spend much of my time on a very large stage. I'll post a pic at
The end. I'm probably 25 feet away, give or take.
I have also played right on top of it, due to lack of space. Vertical dispersion isn't noticeably different from DuallyT. I'm sure there is some. It's just not enough for me to notice. I've never had to move away to hear
myself.
I'd love to hear more about the ported BNA 1822. Has anyone spent some time gigging with one of those? Maybe there is a separate thread that I may have missed.

Thank JGR! He really brought the final design to the table. I just knew what I wanted and had suspicions as to how to get there
You're not too far off comparing a good ported 15" based design to this 18" based sealed design. I am fortunate enough that I was able to compare the 1822 to a ported Faital 15PR400...my favorite full range 15" driver to date. We played with a lot of concepts before committing to what we have and we feel very good about what we have

I play at least two shows a week on fairly tight stages. The vertical dispersion is pretty darn great, honestly. I'm 6'4", so I understand the need for vertical dispersion on a shorter cab!
