Just a few years in the past, OSD Audio launched its TREVOCE line of powered subwoofers. The corporate not too long ago launched a brand new flagship mannequin to the road: TREVOCE 15 EQ DSP subwoofer.

The brand new subwoofer was developed to fulfill the wants of bigger house theater programs or householders who merely needed extra bass of their encompass sound or 2.1-channel stereo programs.

When the corporate went about designing the brand new 15-inch sub, it had a number of factors to fulfill that included high-output with out taking on a number of ground house, and attainability to a wide range of customers. 

I examined the subwoofer by itself and together with different subwoofers in my immersive audio system. 

TREVOCE 15 EQ DSP Subwoofer Setup

For a fairly cheap sum of money, the brand new OSD Audio sub incorporates a number of options. The sub’s foremost lively driver makes use of a graphite and paper composite cone and a pair of passive radiators which can be made with a glass-fiber materials. 

Powering the lively 15-inch woofer is an amplifier that’s able to producing as much as 1,500 watts of peak energy. OSD Audio emphasizes the “triple 15” gives customers with 150-square inches of driver floor. 

In accordance with the Calif.-based producer, this subwoofer is able to enjoying right down to 16Hz at +/-3dB, and may play right down to 14Hz at +/-10dB. 

On the sub’s rear panel are XLR, LFE and RCA inputs, together with speaker-level binding posts, section, crossover and quantity controls. Capabilities of the TREVOCE 15 EQ DSP sub are augmented by the iWoofer app, which is accessible to iOS and Android customers. 

Arriving at my home throughout a blizzard, the packaged subwoofer required the assistance of my 17-year-old daughter to get it into my home (I didn’t wish to drag it by the snow). 

As soon as inside, I used to be in a position to unbox the sub and place it on an Auralex SubDude decoupling base, and I ran an RCA cable to its LFE enter. From there I set the quantity, and downloaded the iWoofer app, which I might use later. 

By way of the app, I ran some measurements to see how the sub match into my 12 x 23-foot room, which took a couple of minutes and that was just about it. I wouldn’t say the TREVOCE 15 EQ DSP sub is plug-and-play — it could possibly be put in as a “set and overlook” sub — however the app is straightforward sufficient to make use of. 

Efficiency and Last Ideas 

The numbers surrounding this product don’t inform the entire story. Once I measured earlier than and after, inserting the sub into my system, there was only some dB distinction. The important thing factor to recollect is the dB scale is just not a linear measurement scale, and the distinction of some dB might be fairly dramatic.

One other factor that I ought to level out is that low frequencies in house environments might be very tough, so the ends in my room could also be fully totally different than the outcomes another person could obtain in different house areas. 

In my room, I used to be in a position to get the sub to play right down to 25Hz with good, stable output. I’ll level out the sub did play right down to 20Hz, however the distinction within the output between 20Hz and 25Hz was noticeable.

The impactful bass was robust right down to 25Hz. Including my different subs didn’t enhance the low-end extension, nevertheless it did add a pair dB of output to frequencies as little as 20Hz.

Utilizing the companion iWoofer app, I used to be additionally in a position to see how the sub built-in into my house house. Seeing the place I had a couple of areas of want, I used to be in a position to tackle a few “comfortable spots” or suckouts that had been leveled out by equalization. 

I used the sub with streaming content material akin to Netflix’s Vikings: Vahalla. I additionally watched broadcast content material, and disc-based content material, together with the Saving Personal Ryan and Jurassic Park Blu-ray discs, and the UltraHD 4K disc of Bohemian Rhapsody. 

On Vikings: Vahalla, the TREVOCE 15 EQ DSP added weight and immersiveness to scenes akin to when the primary characters sailed into Norway throughout a brutal storm on the Atlantic Ocean. Shifting onto the Blu-ray discs, I used chapter two of Saving Personal Ryan, the long-lasting invasion of Normandy recreation, as my reference for listening to what the sub was able to doing in a house theater atmosphere.

Listening to the motion, which was highlighted by bomb explosions and machine gun fireplace, I assumed the sub did a wonderful job of delivering deep, impactful low frequencies with good transients. The bass was not bloated and the sub responded nicely to the dynamics of this 20-minute film sequence. 

Jurassic Park’s chapter 11, Tyrannosaurus Rex, presents a bit of various sort of bass. It’s extra in regards to the depth and influence of the low frequencies on this film, and the OSD sub stepped as much as solidly ship this content material.

Wanting to listen to some Dolby Atmos and music, I performed the recreation of Queen’s Stay Assist efficiency, which is a part of the 4K Bohemian Rhapsody disc’s bonus content material. 

I believe the combination within the Stay Assist efficiency is superior and it’s highlighted by what I might name an especially sizzling kick drum. Listening to Roger Taylor’s kick drum on this combine, it is rather distinguished and an actual check for subwoofers.

The TREVOCE 15 EQ DSP was in a position to sustain with the transients of Taylor’s kick drum, in addition to his ground toms, that are additionally fairly distinguished. 

Between the measured outcomes and the subjective outcomes I used to be in a position to produce by my listening periods, I’m actually impressed with the brand new OSD sub.

I’ll say I didn’t discover the app as refined or as straightforward to make use of as different EQ options, however after a couple of periods of attempting it, I believe integrators will get the grasp of it nicely sufficient. 

As I stated earlier: For a fairly aggressive value, the TREVOCE 15 EQ DSP gives householders a multi-driver, 1,500-watt resolution that’s able to sustaining its musicality whereas producing excessive ranges of impactful bass.
