Good Sound Should be Affordable for All
This is the motto Polk Audio company has been adherent to while releasing their music systems for many years. Long ago in 1971 the founders George Klopfer and Sandy Gross started to hand-assemble the speakers in a protest to the production presented on the American market at the time. They were tech educated and had a good ear for music, but what was more important, they had a clear understanding of how the sound system should have looked and sounded. That’s how the company has started that now has over 70 patents in sound system production all over the world. This subwoofer is surely one of the most powerful among the peers with incredibly high power level. The system relies on powerful 12” low-frequency driver which is responsible for sound reproduction. With regards to the power, it equals 300W and grows in volume up to 460 W of its peak power. The all above-mentioned characteristics make it a suitable option for all customers who look for a budget-friendly sound system with an excellent, rich and deep sounding.

Unconventional Design
At a glance, this subwoofer may seem no different from its counterparts but after taking a closer look we found a significant distinction. The cabinet of MartinLogan subwoofer is designed in such a way that the port and the driver are facing the floor to ensure an even sound propagation. The subwoofer uses a low-frequency driver with a cone diameter of 8 inches that is capable of outputting only 75W in a continuous mode, thus the down-firing design is justified as it provides a bigger range of sound waves propagation with such a moderate power. It is not recommended to place the Dynamo Home Theater and Stereo Subwoofer near the walls or pieces of furniture in order to avoid the low-frequency hum or buzz in them. Thus, it is optimal to stand this home theater subwoofer alongside your TV. With that, regardless of subwoofer’s cabinet direction, the low-frequency sound waves (produced by this model) travel evenly in all directions along the floor.
Setting has Never Been so Easy
The Dynamo 300 is furnished with all the controls required for adjusting the volume and switching the phase of the sound produced as well as for the adjustment of lows. All the controls and connections of the Dynamo 300 are placed on the back panel, so you can easily access them anytime you need. The device has two RCA line-in level inputs (left and right) for the connection to external preamplifiers or devices with a line out, and four clamp terminal inputs for feeding an amplified signal (receiver, amplifier, etc.) to the subwoofer. If you decide to connect the MartinLogan Dynamo 300 to Dolby Surround systems with a built-in sound processor, we highly recommend using the LFE input, which allows bypassing the internal subwoofer crossover. The phase switch offers 0 and 180 degrees options to synchronize the subwoofer output with satellite speakers. You can also select between On, Auto or Standby power supply modes depending on sound playback conditions.
Summing up, we should point out that this music system and home theater subwoofer by MartinLogan is a splendid model for a personal use that makes your sound system’s response reach as low as 32 Hz and improves the overall sound playback quality in your room. We consider this Dynamo 300 powered subwoofer to be a good addition to your multi-channel or stereo video/music sound system for you to enjoy your favorite movies, cartoons or music.

What is a Powered Subwoofer?
Active subwoofers are the systems containing specialized low-frequency speakers (also called drivers) and integrated amplifiers, which are intended for the use in split speaker systems providing a more elaborate bass reproduction. Thus, subwoofers can enrich the sound of your speaker system with more authoritative and informative low-register sound rendering and increase the overall loudness of an acoustic system. We should note that active subwoofers are not self-sufficient acoustic devices as they require tweeters and mid-range speakers (as well as a low-pass crossover filter) for a full-scale and comprehensive reproduction of audible sound. Powered subwoofers make listening to your favorite music or watching movies on home theater systems much more enjoyable.
If you own a car and wish to equip it with a high-quality speaker system you definitely should check our car speakers review to make the right choice and be able to revel in luxurious sound.
What Features to Compare
Sound Performance
When choosing a low-frequency driver or a subwoofer in other words you should first consider its sound performance. In general, the bigger the driver is, the richer and lower, in terms of frequency response, the sound it can reproduce due to its overall power. As a tradeoff for deeper bass, you get the bigger speaker dimensions and weight, though. Actually, the acoustic power and the frequency range, which a speaker can reproduce with adequate fidelity, are two main parameters of a sound performance. The output power of a subwoofer speaker of 100W is enough for covering small premises and enforcing the low-end range of an existing speaker system. Nevertheless, if you want to have a more powerful speaker system that provides sound for large rooms and halls or if you are searching for a professional-grade speaker, you should focus on subwoofers with higher output power. The sound reproduction in low-frequency range occurs within the following sub-ranges (octaves): low bass (20-40 Hz), middle bass (40-80 Hz), and high bass (80-160 Hz). The vast majority of powered subwoofers are capable of Hi-Fi audio playback in 40-200 Hz range while top-tier subwoofers can go as low as 20 Hz.
Box Design
After defining the target sound parameters, you need to pay your attention to a box design of a subwoofer to pick the best option for a required positioning. In terms of sound direction, the drivers are of two main types: front-firing or down-firing. With that, the sound performance of low-frequency speakers is much less dependent on the output sound direction as the one of the tweeters. Despite the fact that some reviewers report a front-firing box design to provide slightly better impulse response values than a down-firing design, none of the designs is inherently superior. Regardless of the box design, you have to pay attention to subwoofer positioning as the sound waves travel in the same way after leaving a subwoofer box. Also, you should think about the measures of decoupling a subwoofer box from the floor to avoid the transmitting of box shaking into the floor.
From the point of view of box ports, box designs are divided into sealed ones (no ports) and ported ones (with a tuned port or a bass reflex). Sealed subwoofers are considered to reproduce the low-frequency sound with more accuracy and evenness. As the air does not move in and out of the sealed box when a speaker operates it acts like a shock absorber and smoothly modulates the forward and backward motion of the speaker cone. The powered subwoofers with sealed boxes are the best those who like critical listening or who are fans of jazz, classical, and acoustic music. The subwoofers with a ported box are equipped with a special port (ported enclosure), through which the air travels out of the box, thus enforcing the sound. Due to a higher efficiency of ported subwoofers, they require a slightly smaller amplifier power to achieve the same loudness level as sealed subwoofers. The bass produced by ported subwoofers is a bit 'boomier' and less accurate than the one from the sealed subwoofers, thus the former suit better for those who like more bass-heavy music such as hard rock, hip hop or electronic dance music.
Controls
Please, make sure that the powered subwoofer you consider meets your demands in terms of controls, which allow tuning the subwoofer to organically fit the main speakers in your existing or desired acoustic system. It is advisable for your powered subwoofer to have not only a volume control but also a tone control, crossover frequency control (defines the higher limit of the frequency range in a sound signal, which will be reproduced by a subwoofer) and frequency attenuator. It is also important for a subwoofer to offer a phase control that enables you to synchronize the sound waves from all the speakers so that they all reach a target location at the same time. Powered subwoofers use a line in for receiving an audio signal, which may be made as mono input socket or an RCA stereo socket. This input interface connects a subwoofer to an audio signal source (receiver, DAC, other devices with an analog line out). Some powered subwoofers support the connection to a receiver or an amplifier via the inputs that pass an audio signal directly to subwoofer speakers, bypassing the built-in subwoofer amplifier. A useful addition is a special clamp terminal that makes it possible to connect external speakers to your powered subwoofer and feed a signal from the built-in subwoofer amplifier to these external speakers.
