PJB C2 Refines Bass Cabinet Size

    The Phil Jones Bass C2 redefines Bass Cabinet size with a vengeance and a mission. It is a 200 Watt shoebox size cabinet containing the smallest speaker ever produced by PJB. It houses 2 of the most advanced loudspeaker units in the world; “Chrome-Dome” technology, exclusively developed by PJB and designed from the ground up as a bass instrument transducer. Amazingly, each speaker is only 5 inches yet are engineered to handle the full spectrum and sometimes punishing dynamic range of a bass guitar.

    At 0.87 cubic feet of space, weight is not an issue so each driver has a large and powerful strontium ferrite magnet. This magnetic material is the most stable available, immersing the incredible electromagnetic force that can be generated by PJB high-temperature voice coils. The voice-coil is the heart of a loudspeaker that takes the full power from an amplifier and converts this into acoustic energy. The voice-coil in the C2 is a result of PJB’s dedication to loudspeaker research for almost 2 decades.

    The difference in PJB’s approach is precision electro-acoustic engineering to enable the musician to fully express themselves without hindrance from an inferior sound product.

    The C2 is dynamic, powerful, clear and has lightning fast transient ability. It follows your individual technique without latency, allowing you the freedom to express yourself as if your bass was an acoustic instrument. It can be used as a stand alone cabinet or in combination with other PJB 8 ohm cabinets or with combos including PJB C4, C8, C27, BG-400 Suitcase Compact, and others.

    Established in 2002, PJB and AIRPULSE Guitar Amps are divisions of Phil Jones American Acoustic Development. PJB is dedicated to using the latest technology in the design of compact bass amps and loudspeakers that achieve highest in fidelity and volume. Phil Jones owns several patents for loudspeaker technology.

    This with an TE Elf might make one cool-ass living room rig. :D

    Was thinking the same thing. Might be the most portable head/cab in the world :)

    I am thinking the same thing as well. Also wondering how it compares with the Cab 27.

    Canada, Eh!
    The website says "PJB employs a full size anechoic chamber for acoustic measurements "...
    so - I would very much like to see the frequency response plots and SPL measurements ( including distortion specs at full rated power). I dunno about everyone else, but for me this would be a seriously big selling point...

    Likewise. But it looks like this is all we get. It does say 40Hz - 15kHz, but nothing about roll-off points, efficiency dB 1 watt @ 1 meter, etc.

    Weight is not an issue, but how heavy is it? I have been looking for something small and portable to use w my tabletop pedal setup or to even toss on the coffee table while playing some grooves. Is this 5lbs or 20lbs or ....? I have a glass coffee table so it makes a big difference to me...plus if I was using this in an urban setting and toting it around town on mass transit I’d also be insterested to know how much of a non issue is the weight?

    also...any idea on cost?

    I am intrigued by the possibilities with this particular cabinet as I really like Phil Jones gear.

    It is worth noting that my Phil Jones Double Four BG-75 weighs only 8.8 lbs. while the C2 weighs 16 lbs., almost twice that. The C2 is also unpowered so it requires a separate head.

  9. Seriously? Why do bass cabinet manufacturers so often omit efficiency specs? They're not even published on PJB's own product page. Can't imagine anyone buying a cab - especially for that kind of money - based just on "Watts"

    Perhaps because their typical buyer—e.g., myself—has no idea what an “efficiency spec” is (unless you mean watts @ x ohms, watts @ y ohms).

    Efficiency spec is how loud the speaker is with a defined power input and distance, usually defined as "xx dB on axis 1 watt at 1 meter," at the rated impedance, usually fed with pink noise, and sometimes in conjunction with a rated frequency response.

    Even then, we all know that is not a perfect spec, either. Think about it: a symphony orchestra on fortissimo passages with full orchestration can put out over 100 dB, but it is spread across the frequency spectrum and dissipated in the concert hall. On the other hand, if you have your ear 1 meter from the front of a speaker, a 1 kHz tone at 100 db will cause pain and/or ear damage.

    Got a pair on order. Hoping for the C8 tone in child size. Ive played many gigs w just 2 pjb 5’s. These new speaks are even better.

    IMO: not for just the bedroom.

    I like the concept behind PJ’s speaker offerings, i.e., a modular setup in which you can use different combinations of lightweight cabs to suit the needs of a particular situation. A single C2 will work great for practicing and relatively quiet rehearsals; two C2s (or a C2 plus a C4) will get you through most average gigs, and a C2 paired with a C8 will blow the heads off of audience members in the first two rows.

    Once youve added the C8, the C2 isnt doing much.

    I suppose not. :)
    You could aim the C2 at the drummer instead of at the audience. The drummer I work with most often appreciates that.

    The catalog copy states that the C2 contains “the smallest speaker ever produced by Phil Jones”—but aren’t the speakers in the C2 5"-ers and the Double Four contains two 4"-ers?

    yeah, i saw that, too --- but i think it meant the 'baddest 5" speaker' in the universe....apparently.

    i like the phil jones concepts. i've never played one to know about a 'fit' for the music/gigs i do. TBH: i don't need any more stuff...but i love those concepts!

    I came for the gimmick, stayed for the tone.

    I'm a Phil Jones fan as well. I really want one of these C2 cabs.
    I have two C4's,a Cab 27& a Session 77 combo. I'd like to try the C2 with the Cabinet 27.
    I did overextend the cones on the 7" drivers in the Cab 27 over the Xmas holidays. Played a small gig where I was told to bring my smallest rig 'cause we would only be playing in a small room & only for 25-30 people. the audience wound up being about 105 in the room. Couldn't run bass through the Fender Passport Pa. Wound up running 400 watts into the Cab 27 & popping up 120 Hz. (Cab 27 only holds 200 watts). Sounded fine at the time but when I used the Cab 27 at a practice session it sounded buzzy!
    My fault! if i used one C4 or had another cab with me I would've been OK!

    Anyone play one yet? Loved to hear feedback with upright bass.
