Manufacturer's Description from APS

SUB 15 is a unique product. In the depths of the infra bass frequencies reproduced with incredible fidelity by the legendary 15 inch woofer from TAD you will find a new definition of bass. Powered by a massive 1000 Watt B&O ICE Power amplifier, SUB 15 delivers an amazing 108dB+ SPL at 20Hz.
Much of what we think is massive bass is really just loads of distortion at 200Hz to 300Hz! Sometimes this distortion can approach 40 to 50% of the total sub output!


SUB 15 is not designed for showing off dirty bass. It is a precision tool for the most demanding engineers opening the door to the "sub 130 Hz" world of the mix. Any judgement call made in that range using SUB 15 will be the right one.

SUB15 is a bass-reflex design for extended bass response. It offers an extended user control via its clearly laid out interface mounted on the rear wall.

SUB 15 is equipped with: two Combo Symmetrical Inputs (Big Jack & XLR), two XLR Symmetrical, not filtered Outputs, two XLR Symmetrical, filtered above 70 Hz Outputs, Input Sensitivity Switch, Additional Input Sensitivity Switch + 6dB for systems with one subwoofer, 0 dB for systems with two subwoofers, Phase Switches (0, 90, 180, 270 degrees), GROUND LIFT Switch, Deep Bass switch, Cut OffSwitch, Stand By Indicator, “Unfiltered Switch” – in the lower position of the switch there’s no low-pass filters active.


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.
