When looking at measurements, one tries to split off ones analysis in the modal region typically 200Hz and below and the region above. I would investigate what's going on at 500, 350 and 200Hz based on the waterfall plot in the midrange, perhaps there is a reason for the energy at those...
The devil is in the detail. Many of these slatted walls are built to serve with a tuned rear cavity only a few cm deep for the application of conference/board rooms where they work really well. I have seen both felt-backed and slotted MDF backed units with open area percentages that somewhat...
tl;dr fiberglass is more absorptive at the same density. Rockwool works great with a membrane front.
Rockwool is cheaper, however the locally manufactured rockwool usually has greater reflectivity and lower absorption than the overseas items. The fiber diameter is greater and more variable than...
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...
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...
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...
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...
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
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.
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...
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...
