Had the pleasure to try one of these last week ; http://www.jblpro.com/installedsound/vpseries/vp7212MDP.html I'm a big fan of small ,light and powerfull and that just redefined my vision. Sounds very nice. Ccompared to similar sized amp this thing is LOUD !!!!! One problem with it is that it is so light , it moves by itself when played loud!!! I already have a RCF 310A wich is 350 watts and 27 pounds , I'm looking forward to acquire one of these for louder gigs. If your looking for a small , light , powerfull rig , have a look at these , plug into your fave preamp and go......
130+ db SPL @ 1 meter; holy crap! Why would you ever need that?? edit: You mean, for use as a backline amp/cab?
Yep. I only use Active full range monitor as bass amp. They are a little under a grand. I'll never complain about my drummer's volume anymore.....
I'm talking of these to use as a bass amp. An Ampeg SVT4pro is rated at 1200 watts.......... So anybody looking for a bass amp of that kind of power but with a small footprint and lots of power would need one of these. Of course you won't have the 30hz of your lower register compared to an 8 X 10" or a 18", but your back is gonna like you.
Watts aren't everything. My Crown K2 has 2500 watts @ 4 ohms, but my Markbass LMII (500 watts) is louder compared to my Line6 pre + Crown.
I know. But like you said ; 134db spl/ 1 meter...... holy sh** People buy heads with 1000+ watts for bass , so 875 watts is not too much.
Yeah, I understand that. I was just commenting on the use it's designed for. But I suppose if the gig is of the magnitude that you have to bring in bass and drums in the monitoring it makes sense. I have yet to play one of those.
I play to ~1000 about once a week. My Schroeder 1210L + Markbass LMII is actually plenty, simply because the bass goes through the board. For medium-sized gigs without PA support, I use my Schroeder 21012L, Crown K2, and Line6 Bass POD xt Live. The only thing is, I love my Line 6, but it's too much to cart around along with my LM and Schroeder. I wouldn't mind having a powered cab that I could carry with one hand, my Line6 with my other, and my basses in a double bag on my back, though, and really, the Line 6 works best with a full-range, PA-type speaker anyway (it has amp, cab, and mic modeling, in addition to preamp and FX modeling).
If it moves by itself on a solid floor then it isn't sufficiently braced and is thus suffering from panel vibrations which won't be good for the sound. Alex
Very few cabs can actually project 30 Hz much, but the monitor cab in this thread rolls off around 80 Hz, which is around E2 (not the low E, one octave up). So I would only use this if I didn't care about the lows at all. And there are already a number of powered cabs which are actually designed for bass frequencies. Maybe stacked on top of a powered subwoofer it would be cool.
Those look like great monitors not a bass amp though. At +3db at 80hz there isn't any real low end there. At that price point Berg IP series for me. The 112 weighs about the same and is in the neighborhood on wattage and actually voiced for bass. Of course this price point is way out of my league but if I had the scratch that's what I'd do.
If only. Manufacturer's 'Calculated Output' figures are about as accurate as your horoscope. They are arrived at by linearly extrapolating the 1m/1w sensitivity figure to the full power thermal rating of the driver. This doesn't take into consideration the real world realities of mechanical and thermal power compression, which will result in as much as an 18dB differential between calculated and actual output figures. The JBL 2262 driver used in the 7212 is mechanically limited to 122dB. Loud, yes, but no more so than any 1x12 loaded with a similar premium woofer.
You just ruined my day if you are saying that even one day when I am playing to a crowd of about a thousand once a week or so, I still might not have roadies. I want roadies more than I want to get paid. I want roadies more than I want groupies. I just wanna rock. I just want someone else to carry my s**t. Is that so wrong? --Bomb
Haha. Well, unlike groupies, you can hire roadies anytime you want. I've had roadies for bar gigs before. It just depends on your budget and how much you're getting paid. Some bars/clubs provide a roadie or two. I just got home from a show with about 800 in attendance, using supplied backline of a Carvin 4x10 with a Carvin Redline 1000 head, with a direct-out to the board. In my opinion, that's even better than roadies - all I had to bring was my bass! I'm gonna go pass out - I haven't slept since Friday night!
