Corus EX Series 3 Extension SpeakerThe Corus EX Speaker Cabinet is specially tailored to the needs of guitarists and other instrumentalists who don't need the extended low range of the Coda EX or Ten2 EX.

Like the Coda EX, this unique amplification system has a downfiring ten-inch speaker and a mid-high driver. What's the difference? The special design woofer, which takes the place of the standard down-firing speaker in the Coda EX. The woofer in the Corus is a more efficient one than is used in the Coda amps and speakers, and the crossover network is changed to accommodate the new woofer. (The other speaker in the cabinet remains the same.) The result is a more efficient, more forward-sounding cabinet. The trade-off is slightly less bass response. The Corus EX sounds louder than the Coda EX at a given level setting and it sounds more forward. It is designed to better match the needs for guitar and other instruments that occupy the sonic space above basses. Frequency response: 60-16kHz (+/- 3 dB) versus 40-16kHz for the Contra EX, and Efficiency: 93 dB/m versus 90 dB/m for the Coda EX.

Ultimately, what you get with all Acoustic Image combos and speaker cabinets is flat frequency response across the spectrum, with extended, tight, well-controlled natural low-range sound — all in a package that's about a foot tall and less than 20 pounds in weight!

Included with all of the combo and extension speaker (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 and the semi-hard case that may remind you of a heavier version of "clamshell" drum cases you've seen. Links to each case are 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.

We can also supply "Cabrio Ready" EX cabinets, giving you the convenience of a combo if you already own a Series III or Series 4 Clarus. There is a small upcharge to have the cabinet built with the Cabrio "dock." To order, simply add the EX cabinet of your choice to your cart - on the cart page, you'll find an item suggestion under "You May Also Need..." for the Optional Cabrio Dock. Add that to your cart and check out, we'll send you the Cabrio Ready version of the cabinet. Note that Cabrio Ready cabinets are subject to a possible "build-up" delay as they are a special order item.

Note also that Acoustic Image can modify your existing Series III Clarus or Focus; contact them for details and pricing.
The Acoustic Image Corus bass amplification system was designed to accurately reproduce the sound of guitars and other stringed instruments like cello, violin/viola, harp, etc., as well as a long list of other instruments - using one small, easy-to-carry enclosure. Instruments with a stronger bass fundamental (acoustic-electric and upright bass, keyboards, electric piano, larger harps) would be better served by the lower-reaching sonic abilities of the or Coda or Ten2. Ask us about any of these amps!

About the 2-way cabinet (didn't AI combos used to have a tweeter?)
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
  • The new driver uses a neodymium magnet; which, when combined with the eliminated tweeter, reduces the weight of the combos by nearly two pounds

    • Two-way Sealed Speaker System
    • 10" Long-throw Low-frequency Woofer, special design
    • 5" Mid/High-frequency Driver
    • Neutrik Speakon Speaker Jack - no cable included, check our cables selection for options
    • Lightweight- less than 20 lbs! with new Durable Molded Enclosure
    • Molded Carry Handles
    • Dust cover with cable pocket and shoulder strap included
