![]() ![]() I've tried setting up a two-way system with the Axiom bass and Wharfedale Super 3 tweeter with a point of crossover around 5-6 kHz and got a reasonably flat response. Above modelling for a potential two-way system with a point of crossover around 2.5 kHz. The following three graphs were made in LspCAD just to get an idea of how easy - or difficult - the Axioms would be in more conventional applications. Reading normalised for 2.8V at 1 meter distance. Vent tuning is 45 Hz = two holes in front panel of 75 mm diameter.įrequency response of two drivers in test cabs, quite nice. Right: Impedance of driver in my 95 liter test cabs. All the ripples on the graph reveal suspensions not working properly, but it's been seen worse, much worse. As can seen, the Fs of the restored drivers are fairly good, but compliance of suspensions are not exactly the same, one driver having a more narrow impedance peak compared to the other. Left: The impedance curves tell a lot about driver performance. 150 liter would take the response down to 40 Hz, but these drivers will be tried in an open baffle construction. My Tannoy test cabs will serve as initial cabs for these drivers and a decent alignment can be a achieved giving a good response down to 50 Hz. As can be seen there's a good correlation between data. Two things from the above LspCAD modelling: The Speaker Unit Editor is a great feature allowing you to check your measurements by cross calculation. ![]()
