Focusedon comprehensive weather realism simulation, ASFS includes high-fidelity weather data and synthesis, planning, briefing, mapping, live weather, optional historical weather with playback, custom weather, scenarios, API, multiple depiction options, active air effects, snow depth data control, voice features, Navigraph and SimBrief integration, and much, much more.

ASFS Preset weather and Passive weather depiction modes

Using Preset weather depiction from ASFS or Passive weather depiction (from MSFS live weather), a variety of weather visuals and depiction methods, offering various levels of realism, control and visual quality are available depending on your needs. Transition control and configurable smoothing is also provided in ASFS Preset mode.

Active Air Effects

Customizable clear air turbulence, thermals, drafts and wake turbulence effects work in tandem with existing MSFS effects to provide and enhance realism. Air effects are provided in any depiction mode.

Advanced Historical Weather

In addition to including Live and Custom weather modes, we also offer Historical mode with comprehensive global weather data in hourly archives. Dynamic historical playback provides realistic changing weather as per the archived historical timeline. Optionally lock the historical time to your configured simulator time for easy date/time synchronization and control through MSFS.

Enhanced Cloudscape and Thunderstorm Depiction

Using ASFS Preset weather depiction, enhanced sky condition and thunderstorm handling works to increase the visual realism and overall experience of various weather conditions including thunderstorms.

Active Sky Weather Engine

24 years of active development of weather simulation for MSFS and other platforms culminates in a mature and refined weather engine system that natively includes advanced weather data analysis, lookup, mapping, planning, briefing and more.

Advanced Data Collection, Synthesis, Modeling and Interpretation

Active Sky constantly downloads and analyzes conditions, providing world-wide high-fidelity weather conditions and effects, utilizing surface airport conditions (METARs), Forecasts (TAFs), Upper air data (GRIB), Significant Weather information (Sigmets/Airmets), Tropical storm data and more. Weather data is offered in live real-time or historical modes, with a dynamic historical weather playback feature.

Comprehensive Custom Weather

Easily create multiple custom weather areas using the map screen, customizing by METAR text or through our weather setting wizard. Custom weather is supplemented by the previously loaded weather, enabling precise, variable and realistic saved weather scenarios that can be recalled at any time.

3rd-Party Integration Features

Navigraph data integration, SimBrief flight plan integration, PMDG wind data export and our universal common data export features provides integration with multiple popular 3rd-party add-ons.

Active Sky API

Advanced API features are available to everyone to integrate directly with AS features including weather lookup, effects, mode control and weather conditions control.

ASFS Preset Weather Depiction Mode

ASFS Preset weather depiction mode features advanced weather preset conditions control for the best accuracy within the preset depiction capabilities, and full use of the Active Sky weather data and synthesis system including historical and custom weather options. This is recommend for those desiring the highest levels of conditions realism and challenge, especially for IFR ceilings and visibility, as well as long distance route planning, wind and fuel calculations:

There are of course downsides: ignoring any cost difference between the active and passive crossovers, you need twice as many amps for bi-amping a two-way speaker and three times as many for tri-amping a 3-way. And that also means greater complexity and system bulk.

My personal experience comparing is with PMC EB1i speakers, the passive using a Musical Fidelity P270 power amp, active (with passive crossover removed) was using the P270 on bass, and MF P170s on mid and on treble fed by a stock Behringer active XO. The bass seemed tighter, and overall clearer. To be sure I wired the passive xOs externally and had my son change over a few times so I was assessing blind (no, not double blind but my son enjoys the challenge of fooling me with blind testing, e.g sometimes one a bit louder, sometimes the other).

Interesting, I think another consideration is going active limits the speaker choices. If all speakers could be run active through an easy mod perhaps the results might be different. Having said that the impression I get is the 500 is a stonkingly good amp.

I wonder if an active SBL setup with my 52/135 on the tweeters and say an olive 250 on the mid/bass driver would better my Harbeth 30xd for drama. This is the one aspect I miss about the 552. The leading edge was so punchy.

I think it really depends on the speakers. Older Linn speakers like Isobariks are transformed by going active. More generally, active is a different presentation, speed being one word that springs to mind. But the proliferation of boxes required is going against the current trends I suspect. I like the idea of a single box at the 500 level, or even the statement (out of my reach) but I would have to replace my speakers (Briks) as I think they would be holding the system back in passive and then it gets costly again.

You can of course get all the benefit of active without the complexity. If you can find a pair of single driver crossoverless speakers that you like, you can basically get the benefit of active with the same speaker cable and just an integrated amp - no active crossover required. I actually do this with a pair of Omegas driven by a little Luxman integrated.

After going active with Nac 52 , 3 Nap 250-2s, 362, CDS3/555PS, and NBLs, I would have a difficult time returning to passive operation. However I have never heard a 500 level amp and preamp combo. I think all Naim speakers that were designed for active operation will exhibit improvement over passive. My NBLs certainly do.

Now, active speakers. These have amplifiers built in as well, but this time they have one amp dedicated for each 'way'. So, a two-way speaker with one tweeter and one mid/bass driver unit will have two power amplifier modules. These models are fed by an 'active' digital crossover that works at a much lower voltage than their passive cousins. That means the components can be optimised for precision rather than pure power handling, resulting in a potentially better integrated, more precise sound.

Optical and HDMI ARC can both carry stereo PCM (uncompressed) and Dolby/DTS 5.1 (compressed), though HDMI eARC has greater bandwidth and can therefore transmit the next-gen Dolby Atmos and DTS:X surround sound formats. This distinction shouldn't make much difference to how you listen to TV via your stereo active speakers, mind you.

Yes, but either (or both) your active speakers or turntable must have a phono stage. This is necessary to raise your turntable's audio output to line-level and deliver a sound you can hear through your system. At the same time, it also adds standardised equalisation.

If your turntable has a built-in phono stage, it can connect directly to an active speakers' RCA inputs. If it doesn't, it can connect to your active speakers' dedicated phono-toting RCA input (typically this comes with a switch to turn the RCA input to 'phono' mode).

Suppose you want a hi-fi system but are daunted by the prospect of multiple speaker and amplifier boxes or simply don't have space for separates. In that case, you may want to consider active speakers i.e. speakers with amplification built-in.

While most of the products on this list might look just like standard passive speakers, don't be fooled: there's a lot of power and clever processing going on inside these cabinets, and many of them support hi-res audio.

There's analogue and digital connectivity, often conveniently complemented by Bluetooth support too. And some are also complete hi-fi systems, with wi-fi connectivity and integrated access to music streaming services. Not only are such active speakers more practical and neater than a bunch of separate components due to their relatively compact size and reliance on cables, but they are also often cheaper as well.

Not quite sure what you're looking for? Our how to choose active speakers section below will hopefully help. But if you do, jump straight into our list of the best active speakers you can buy, which have all been thoroughly tested in dedicated test rooms and handpicked by our in-house experts who have over 150 years of collective experience.
