Why would they need to exagerate the weight figure, given that even23lbs is already amazing for a 212?

And if you open the discussion about the weight, I'd like to talk about the sensitivity: how could the 210 have a sensitivity of 103 dB SPL, seriously? (same as for the 212 by the way)
I was wondering the same thing, so I reached out to them via email to confirm the accuracy of this. They replied confirming a sensitivity rating of 102.6 for the 210 and 103 for the 212.

Given 98dB for the 110 and 104dB for the 410, a value of 101dB would make more sense for the 210. It might depend on whether they were using 1W or 2.83V values. Doubling the number of drivers typically adds 3dB to the sensitivity.

This 210 cab would be louder than a SVT810, or a Mesa Subway 215. Louder than anything you know except bigger GR Bass cabs, and it weights only 7 Kg - 15,4 lbs.

And then the AT610 and the AT810 both have the same sensitivity of 106 dB.

.

These seems too incredible to be true.
A 2x10 that is louder than a modern 2x15 or 810?
I'm guessing that there must be huge low freq trade offs.
Or are we adding new pages to physics books?

There is more to a speaker then its db rating. The numbers don't tell you what it sounds like.
Three speakers with the same db rating can sound vastly different.
My AT212 sounds good to me, has plenty of bottom end, can keep up with a loud band, and is an easy carry.
Checks all of my boxes.
Buy a GR Bass cab, compare it to what you have, and then sell the cab you don't like.
 
I have a AT 112 in wood / 450 watt rating / 8 Ohms
I'd like to get another. Not always easy to do.

I call BS on the SPL ratings assuming they are full range bass tone (like my 112) & not sounding like a fire alarm.
I normally use a 2x12 GB NeoX and my single 112 GR cabinet is definitely not as loud or will fill a room as well. It is very clear and musical though.

I just ordered a pureamp 800 as a portable alternative for my ampeg SVT-300 full tube power amp . It is (was) in stock. I hope it delivers more than the portability: 20 times less weight. That is the only reason I can justify purchasing it.
I never played a class D amp before: Yamaha BB NE-2-->Limiter-->Tuner-->HPF-->BK7 ultra V1--> ...--> ampeg 610.

I am a very happy owner of an AT212 Slim cab and a Pure 800 head. Definitely the best rig in my possession at present, out of a collection 8ncluding Markbass, Fender, Mesa, Darkglass and several others before that lot. I'm mainly using my GR Bass cab and head with my Tech 21 Flyrig or my MP40 at present, but I have an Ampeg SGTDI on the way soon and I think the SGTDI/Pure 800/AT212 setup is going to work as a fantastic rig in so many different respects. Will report back to update very soon.
 
I would contact [email protected].
The GR Cube 110 seems to have a standard input found in most amps.
I noticed that the AT Cube Acoustic has a special input for Piezo.
AT Cube Acoustic – GRBass
I asked GR support, they say the input impedance is 1Mohms, it's pretty Ok. for upright, (same as famous GK MB150). Off course higher is better for DB, but I find a good deal for 110 Cube….

Just came in two days ago. Always gives me the same sound at any master level. And it stays stabile. It gets warm after an hour of playing but not hot. Nothing but love at first sight/hearing.
Our singer asked me why I took a playstation along. Everybody in the band was quite happy
 
Pure switch is near the center of the amp.

Hi I am contemplating the Gr Bass pure 800W version - its very attractive to me because of the 2 knobs thing. I play serek and fender P with flats fingerstyle and thats the sound I want. I already have an aguilar Db925 and the the tonehammer preamp and the origin fx bass compressor so tonewise i do not need an onboard Eq - it least thats my thought. However, the pure is more expensive than the one amp - with less features and you can switch the pure to a one with a switch. Are there any other differences that motivate the higher price on the pure, except the coolness of 2 knobs? My other alternative is a Aguilar TH 500 or 700... What do you think guys? There are practically no reviews on the pure 800 out there...
