    Room Measurements and treatment required- KZN

    For most room decay/RT60 measurements, any mic will give you a relative starting point, even the units from a HT receiver. A mic and measurement software remain a tool in the service of the listener, please don't chase specific measurement targets unless they're way out of bounds and rather see...

    Room Measurements and treatment required- KZN

    Those slatted panels are a perennial favourite for smaller auditoria and wooden finish board- and conference-rooms. As always, the devil is in the details and the backing on those often presents as a reflection at 1/4wl when backed and spaced off a wall. For bands 300Hz ->2kHz it often works out...

    Room treatment advice

    Can you manually set filters? Some EQ filters moves seem a little counter-intuitive.

    FdlSys - Sad news

    I have no words. Truly a sad day.

    AV Lightning protection

    I would say the old approach in datacenters used to be a generator on a shaft driven by an electric motor and a local mass/earth that is isolated from a near strike by means of a resistive ladder approach linked to a faraday cage and IT earth topology is perhaps the most effective decoupling...

    Lavazza Coffee is back (for now)

    Woolies coffee is (or used to be) to the best of my knowledge made by Tribeca. Steam roasted wont bring out the bitter kick of a hard drum roasted Illy/similar traditional italian roast. For fine grind high roast coffees in an espresso nobody will say no to R100/kg hard roast though it does...

    Home Cinema build - Dedicated room (50% complete)

    In a dedicated build, do fewer channels better rather than "bounce". Rather look at the acoustics or getting other areas like the naturalness of the narration better

    Krix Home Cinema demo room (Johannesburg) Elan Systems South Africa

    Nice to see some QRD diffusers in the back, what's the RT60 decay like over octave 1/3rd octave bands?

    Next Generation Ford Ranger Subwoofer Installation

    Start with a transfer function measured in vehicle, target post EQ response and then optimise output in model for the available volume and space factor. Anything else in a car is just glorified taxi bass.

    Help with a 5Kw good system both cost wise and product wise

    The 6kW SNA is not the lxp 5k. The Lxp is more in line with the deye products. For many people relay control on the geyser (changeover to grid, not on/off) and a timer make a 6kW system more than suitable. If one starts with an energy audit and does an hour-hour (EU PV GIS) historical analysis...

    Help with a 5Kw good system both cost wise and product wise

    The Luxpower SNA has the NRS cert now so you may grid tie. They are also bringing out the 6kW with external current clamp. For R10k less than a 5kW Sunsynk, the difference being a few digits % on end to end efficiency, warrantee and a fan. I don't believe that all that many folks will benefit...

    One big sub vs multiple smaller subs…who will win?

    It's all in the implementation and the room specifics. Sometimes even small subs will do ridiculous LF, it all depends on how the room's modes behave and how the setup optimizes the behaviour. The size of the sub(s) is oftentimes irrelevant.

    Building a Yuich Arai 290 Horn (or two)

    There is some theory behind the adaptors, a simple loft does work but it's not the correct way to optimize the interface. You need to model the horn from the diaphragm and phase plug onwards. I have done 480s and both types of 290s and they work well with some compression drivers but not all...

    Building a Yuich Arai 290 Horn (or two)

    A290s are a bit of a bear to make neatly CNC wise, the smaller FL is doable but the A290 is indeed quite a setup. I have a 480 as a monitor stand showcasing a small CNC setup slip-up for example.

    Bad Acoustics Affecting Your Parenting?

    Perhaps it's those with treated rooms who are horrible. :ninja:Nowhere in nature will you find the sound of a box, it has a profound impact on us psychologically and for some physically. Softening the visual and auditory stimuli helps a lot for my family. Being outdoors more likewise helps to...

    Bad Acoustics Affecting Your Parenting?

    My wife and daughter have spectrum related sensitivities and they both love a well treated room. I have consulted on a few therapy rooms and it's amazing how that translates to the kids. The modern architectural environments we place ourselves into are more and more aggressive and it is amazing...

    To add 2 x speakers to 5.1 home theatre (with existing room & placement limitations) or not ?

    With the sides so close to the listening position and the comparatively narrow width....I would suggest rather look at tweaking elsewhere though it'll never hurt to play around some temporarily if the kit is standing around. The sides also have a reflection opposite (also near) and quite...

    Speakers for an Exclamé 100 in a big room

    Let's give an example: I have just this week set up my test rig for the first time this year. It's an honest 92dB sensitive 2-way with a 89dB sensitive sub powered by a 60Wpc amplifier, it gets quite loud for my ears in my 35m^2 room but it has its limits (mostly the 60W on the single sub). It...

    Speakers for an Exclamé 100 in a big room

    With an integrated, usually there is no high pass filter on the main channels (the filter gives the main speakers a break). Few people venture into legit bi-amping territory. If the levels are fine but you wish to get more grunt down low, the subs might be the answer here, if it's the overall...

    Speakers for an Exclamé 100 in a big room

    You only get the headroom increase when you have the crossover to go with it unfortunately. You can however gain more even bass and more bass heft overall. Regards measurements, the marketing department is at fault here nearly universally. At one stage Tannoy rated their speakers 4pi anechoic...
