APS Trinity Active Studio Monitor Pair  From APS

APS' three-way monitoring system featuring a sealed cabinet design for optimal punch and focus across the entire frequency spectrum!


Manufacturer's Description from APS

Trinity combines all our experience in speaker design into one powerful, precise and overwhelmingly realistic sounding package.
What You Hear is What You Get. When mixing any material, be it a hit song for an upcoming album or a soundtrack for a blockbuster movie, you want to be able to rely on what you hear. The mid driver used in TRINITY provides the missing link, giving you unprecedented control over that frequency range. Get hold of your sound. You will never let it go.

Custom designed class A/B power amplifiers power each driver separately to deliverer a total of 500 watts per monitor. That's 1000 watts of combined power for never ending crescendos.
As is customary at APS, high quality SEAS drivers ensure perfect sound restitution, encased in a very rigid enclosure for maximum fidelity.
We designed TRINITY to be the most realistic speaker possible. TRINITY is the king of the medium and large listening rooms. It is the best sounding three way far-field monitor in that and much higher price range.
All our speakers are available in any color or natural wooden finish. In both cases it is possible to order either matt or polished versions. We can customize the speaker to any finish available on the market based on client's request. Please contact us if you need more details or to discuss individual finish.

The APS Klasik is one of the newer offerings from APS, where they set out to build an excellent monitor at a reasonable price. They have stated they have no plans to build anything cheaper, as it would wind up compromising quality to do so. Most of the work into it was in the cabinet tuning and the crossover circuit. These are a great option for home studios, and if someone needs something more portable. Having RCA inputs as well allows you to even run an unbalanced input straight from your phone with a Y cable. The Klasiks are also available to order in a Hi-Fi version at the same price, with a standby power mode and front mesh to protect the drivers. 
The original APS monitor, which is significantly larger than the Klasik, even though the bass driver is only 1" larger. It is more designed as a mid-nearfield, and as such we do suggest a greater listening distance of 3' and up ideally. Being more room sensitive as well than the Klasiks, this is more geared towards advanced home studios, or professional facilities. Translation on these has frequently been commented on as being effortless. The vast majority of Aeons we supply are with the Fabric dome tweeter installed, and in most rooms, they work best with the tweeter rolled back ~1.5db. With the bass extension by-passable on these just like on the Klasiks, you can have a faster mid-range response, at the expense of less low end extension. These do not require a sub unless you are working in a large control room (suggest 500sqft and up). Even then, if you have them positioned properly, it would be best to take it as a case by case basis.
Some reviews online have put the Klasiks as above the Aeons, but in every single demo I have done having them both properly set up and tuned to the room side by side, the Aeons win hands down. A lot of it is just that the Klasiks are more room forgiving, and don't require the attention to setup to the level of the Aeons. 
These are more of a specialty item, for clients looking for massive and detailed stereo fields. They were designed for imaging, and are not as flat as the other monitors from the line. In smaller studios they do work well by themselves for acoustic work, however in most cases, we do pair them with a subwoofer. These are the only sealed cabinet of the monitors from APS at this time, and as such do not have the same low end punch the other models have.
These monitors are designed for larger studios, and really offer an exceptional all around performer. They have a massive stereo field, exceptional detail, and are very smooth and full. They offer essentially three monitors in one with their different modes, accessible via switches on the back panel. You can run them as a Three-Way, woofer bypassed (standard 2-way) or midrange direct (mixcube style). Even in fairly large studios these will seldom require a sub to be even considered. Although they can be used as near-fields, we suggest them being at a mid to far-field position to be able to really hear them properly. and get the best from them. Keep in mind these are LARGE, being 2 feet x 2 feet x 1 foot, and over 80lbs each. These can be ordered in either a vertical or horizontal configuration, or even as floor-standing tower speakers. 
Versatile sub, designed to be very clean, and low distortion. Variable LPF to allow for matching with many different monitors. Precise level tuning and phase reverse to allow proper setup. 
Designed more so as a low frequency extension of monitors, to make them resemble large mains rather than smaller monitors + sub. Exceptionally smooth and balanced. We do not stock these, as they are special order only.
