Re: T/S parameters valid for normal listening levels.
Right, Thiele / Small parameters only define the behaviour of the driver in the acceleration (rising response) band up to the mass corner frequency in Hz ( [2*Fs]/Qts) while factors like Rms start to fall away even sooner, at roughly Fs/Qes. Wiggle room there definitely is; I'd always recommend usin...

Re: T/S parameters valid for normal listening levels.
Of course. Thiele / Small parameters (which are just a way of expressing the EM behaviour of a drive unit) are not strictly speaking fixed, but can vary with voltage drive. In the original intent, small signal values were measured at relatively low levels [natch], and a lot of home & pro. measur...

Re: Return of the Triffids
1/4 wavelength spacing out to the upper limit of the transition band is the 'ideal', especially for something like a Unity horn as they effectively sum as one unit; for roles where conditions are a bit less demanding as in something like one of these baffles, up to 1 wavelength is generally fine, al...

Re: Return of the Triffids
Right. The focusing will be partly for aesthetic reasons, since assuming a 500Hz crossover frequency you'd need a c.27in separation for the four LF units to have obvious integration issues if mounted on a flat panel. That said, crossovers are not brick walls, so you have to consider the slope and th...

Re: Return of the Triffids
The logic for facing the drivers the other way other than to compact the design, would be to bounce the LF off a boundary. I stand to be corrected. It's a dipole, so the LF emits in a figure 8 radiation pattern, i.e. equally (albeit with a 180 degree phase difference) front & rear of the cone. ...

Re: KEF Meta Absorber
I'm not sure it would be ideal for those drivers. You don't exactly want to be depressurising a compression unit, and this is likely to be a better solution to slightly larger chambers where eigenmodes can be an issue. Not impossible of course, but I suspect alternative solutions are likely to be mo...

Re: KEF Meta Absorber
It is. Although it can take some careful juggling of the type used, its quantities and location for best results, and if combined with rear decompression chamber[s], it gets a little more complex as there are usually some other effects coming into play (typically in the 2KHz region). Nothing particu...

Re: Purifi-based monitor - options
Missed this as I'm away from home & not much audio time, but -question? Is that SPICE circuit diagram showing the actual LP, or is it also indicating some kind of approximation of the driver impedance? If it's the former -watch out for the power-handling on R2; it will be shunting a considerable...

Re: Fane 12-250TC Retro Speaker.
I can't supply pictures as I'm currently lecturing in Barrow, but a traditional favourite is to cut a ring of thin cork, velvet / synthetic velvet or similar and use that, with or without a template. We did the latter at MA-Sota on the Viotti Ones and nobody ever complained about their appearance as...
