|14 Day Trial Period on Series 4 Acoustic Image amps and speaker cabinets|
New owners have a fourteen day trial period during which they may return the amp in new condition -- NO QUESTIONS ASKED! -- for a full refund, minus our outgoing shipping cost and a small transaction fee to cover credit card processing. Returns must be preauthorized; a restocking fee applies if the unit is not returned in new condition.
|The Contra is Back!|
Acoustic Image was first on my personal Bass Radar in the late 90's, when I first saw some buzz about this revolutionary new down-firing bass amp. My first Contra arrived in 1999, and I took it to the NAMM 2000 show in Los Angeles, to demonstrate K&K Sound upright bass pickups in their booth. At one point, Dieter of K&K borrowed it, to see how his acoustic guitar pickups sounded through it.
It took me six hours to wrestle it back from him. The Contra was that good. And now, along with its many siblings, it's even better, thanks to its many updates and improvements over the last dozen years.
These combo amps were a real breakthrough when first developed by Dr. Rick Jones, a bass player (check out his CD at right for firm cred) as well as Founder and President of Acoustic Image. They continue to get even better with each generation.
The design and performance of the Acoustic Image Contra was -- and still is -- quite revolutionary. The lowest bass frequencies are omnidirectional, and we all know our acoustic instruments do not radiate only in one direction — their sound moves about the room. The ten inch down-firing woofer in an Acoustic Image combo spreads that sound around naturally, as our ears might expect. But there is still plenty of definition, and it's not as annoyingly directional as so many other amps.
And that's only one of the differences between it and other amps. This combo has a specially matched set of drivers that results in a full rangespeaker cabinet. In addition to the woofer, you'll find a five inch cone mid/high driver. Plug your MP3 player in and be amazed at the result! Nice tight bass, real, uncolored sound.
The other key ingredient in Acoustic Image gear is the electronics. They have been designed to deliver the natural sound of your instrument, no artificial flavorings or colors. Why is that good? Please answer this question... do you want to hear your instrument or the amp??
Me, too. My specifications for an ideal sound is for a pickup/mic and amp to simply make my bass sound bigger.
More Power!! (please insert your own Tim Allen Home Improvement TV show grunts). 300 watts of constant (RMS) power is quite good, but keep in mind that the Contra is not a rock-n-roll amp — it's not going to replace your 4x10 for duty in a Led Zeppelin cover band. Yes, it can get quite loud, but the wattage is there to ensure smooth, clean response. Bass frequencies take a great deal more energy to produce than high frequencies, and the somewhat percussive nature of upright bass can be very demanding. The wattage is there so the energy is available to cleanly handle those peaks and percussive plucks, rather than that "squashed" sort of attack many bass amps often deliver when they hit the wall.
Features have been designed into the newest Contra model to add flexibility for various playing situations. These include a parallel effects loop with a return level control, a selectable high pass filter for feedback or “boominess” elimination (see explanation in features list below), and a balanced direct out with ground lift to allow connection to a mixing board for PA augmentation or recording. A redesigned built-in mechanism allows the cabinet to be tilted to better direct sound to the player’s listening position. For larger venues, the Contra EX extension cabinet is an ideal match.
|About the 2-way cabinet (didn't it used to have a tweeter back in the day?)|
Note: in late 2010, the Acoustic Image combos and speaker cabinets evolved from a three-way (Woofer + Midrange + Tweeter) speaker array to a two-way (Woofer + Mid/High Driver) arrangement. The original tweeter was crossed-over at such a high frequency that some folks couldn't even hear the difference when it was on or off! The new arrangement actually has several benefits:
- The new proprietary extended range driver, exclusive to Acoustic Image, is smoother and more detailed than the previously used midrange and tweeter combination
- Using fewer speakers to cover the full frequency range reduces phasing and amplitude anomalies caused by crossovers in multi-speaker systems (translation: all things being equal, two-way systems are better than three-way)
- The new 5" driver has higher power handling, providing a bit more perceived volume and definition when needed
Included with all of the Contra, Corus, Coda and EX models is a lightweight "dust cover" with shoulder strap and accessory pocket. Made of lightweight vinyl, it covers the top and sides of the cabinet, with openings to allow access to the amplifier's integrated handles. It also comes with a carry strap which loops through the openings and the amp handles, allowing you to "shoulder" the amp. The cover is handy - it even has a small pocket for cables, tuners, and other small gigging accessories. But don't expect it to substitute for a case, as it offers only minimal "protection" from slight bumps and other minor hazards. If your gigging needs require something a little more protective, we have other options available separately. Check out the optional padded Mooradian case in the Related Products, below.
The photo at left shows it with the cover on and carry strap ready for transporting. A zippered pouch is provided to carry the power cable and other small items, shown in the photo to the right (without the carry strap). This light-duty cover will not shield the unit from rain, and it does not cover the bottom of the cabinet.
