What We Think

This amp packs a serious punch! With both forward and down firing 10 inch speakers, this amp can handle a broad range of thick sound that amplifies your acoustic instrument and takes your performance to the next level! flat response that brings out the true tone of your fine acoustic instrument.

Major flexability and portability in this great 2x10 combo amp! I was amazing at the natural sound and power this amp puts out with a McPherson acoustic plugged in.  Even an external L.R. Baggs pickup like the M-1 sounds very nice through this amp.  Also works well for keyboards, bass, cello and a variety of other instruments.

Manufacturer's Description from Acoustic Image

Design Goals

The goal for the Ten2 was to produce a 2x10 combo amp unlike any other. We wanted it to be smaller and lighter than any other on the market and we wanted it to be "in the family" sonically but with the more up front sound usually associated with a front firing cabinet.

The Ten2 was designed to play louder than our other combos to give the player more flexibility in the settings in which the amp is played. For example, the Ten2 is comfortably used in electric bass situations that would be too loud for our other combos. The Ten2 has the added versitility of the removable 600W head for even louder situations.

Small size and light weight were paramount. At 32 lbs and 17 inches tall, the Ten2 is the smallest and lightest 2x10 combo on the market. The Ten2 EX is even smaller and lighter at 25 lbs and 14 inches tall. Even with the compact size, this is a "no compromise" combo. The head unit is the same as the Clarus with all of the features needed to meet the most stringent requirements of musical instrument amplification.

The broad frequency response, high power output and smooth, high fidelity sound make the Ten2 the ideal combo for all applications: acoustic bass, electric bass, guitar, keyboards, vocals, etc. Think of it as a high performance, compact PA system.


The two-channel, Series 4PLUS Ten2 has two separate channels which can be used to blend two sources - two different pickups or mics (or a combination of the two), or two different instruments. The XLR and ¼" inputs are on separate jacks. Additionally, they are separately buffered, which means that you could effectively use both at once, on each channel. You would only have independent control if at least one of those sources had its own volume control (like a keyboard, or an instrument with an outboard active preamp) but it does open up the possibility of actually "mixing" up to four different sources.

The preamp features a new four-channel equalizer, as follows:

Low: Shelving, ±12dB at 50Hz Lo Mid: ±12dB at 250 Hz Hi Mid: ±12dB at 1200 Hz Treble: Shelving, ±12dB at 8 kHz

The built-in Digital Effects can be assigned to either channel (or both/neither), and the amount of the effects in your mixed signal can be adjusted with the level knob. The rate setting is now configurable (!) and the effects include the following presets:

Reverb Delay Reverb PLUS Delay

One last new feature - illuminated on/off buttons for the front panel controls to indicate whether the button is on (lit) or off (unlit). This is really helpful on a dark stage!

About Manufacturer

Although Acoustic Image is a relatively young company, it is owned and operated by people with decades of experience in the professional music and sound industry. They're engineers (and, like their customers they're also musicians) who insist upon superior sound quality and reliable performance from our audio equipment. Acoustic Image was founded because they were never satisfied with the products available for the working musician. If you play guitar or bass, violin, keyboard, a woodwind or even a brass instrument, or you are a vocalist, they've got a sound reinforcement product designed with you in mind. Great product designs go far beyond having the right knobs in the right places. Acoustic Image’s company charter is to design and build unique, innovative, and functional audio products... there is nothing "me too" about what they do. In essence, they have merged advanced acoustic design and switching amplifier technology to create incredibly compact, ultra-lightweight products offering highly accurate sound for serious musicians. Ultimately, their pledge to you is for quality... to build a well-constructed reliable audio product that serves you well night after night, year after year. And, quite frankly, they believe the best way to do that is to design and manufacture each and every Acoustic Image product in the U.S.A. Their Technology Applying "musical thinking outside the box", they have taken a different approach to the technology of musical instrument amplification in order to improve the performance and portability of combo amps for the working musician. So, what's so unique about their products? There are three key differences: 1) The use of downfiring low frequency drivers 2) The use of switching power amplifiers and switching power supplies instead of the traditional linear designs 3) The use of unique enclosure shapes to improve portability and sonic performance Each of these differences provides an improvement in the performance of their products. Here's how: The downfiring woofer makes a small driver sound bigger and allows a smaller enclosure for a given driver size. Omnidirectional output produces a more natural and more transparent sound, and means you are more easily heard on the bandstand. The switching (Class D) amplifier design is smaller and more efficient than traditional linear amps. It has less weight because there are no heatsinks or cooling fans and it has a unique "warm" sound (unlike traditional solid state amps) because its output stage is radically different from traditional amps. The switching power supply eliminates large bulky power transformers with a resulting dramatic decrease in weight. With their unique enclosure shapes, form follows function. A cylinder is an inherently stiffer enclosure. And no resonances in the enclosure walls means less coloration in the sound. Also, the stiffer enclosure allows the walls to be thinner and lighter in weight. Add to that the use of acoustically inert polymer materials and the cabinet becomes ultra light. We don't use these new technologies to “be different.” They use them because they make their products better. It all adds up to a more portable, better sounding products. Because of their small size and high sound quality, they virtually disappear on stage, leaving the sound of the instrument being amplified, only louder.
