OK, here is a pic of the bit of grille engineering I did behind the front Fender Tweed cloth:

Image

As we can see, there are three grilles in total (including the front cloth)
The larger of the two auxillary grilles has a bigger cat's eye than the smaller circle, so the
two eyes are concentric with each other. Works a treat :)

Indeed! :lol:

It may be old school, but it works beautifully. I’m sure the Doc would have approved.

Here’s a bit of measurement, and it backs up the subjective listening experience perfectly. Sometimes, measurements can be useful :mrgreen:

Below we have the pink noise spectrum analysis of the speaker frequency response, from 12 months ago, taken sans grilles:
Image
It’s only 3rd octave; nevertheless, the coarser resolution is sufficient to see the rising overall response, and peaks at 4K and 8K can be seen. These can be highly annoying on the wrong recordings.

Now, let’s have a look at the latest 6th octave pink noise, spectrum analysis, taken today, in room at 1.5m, distance, centred between the two speakers at 10deg off-axis, with the secondary grilles in place. This higher resolution analysis was taken at the same point in the room as the older analysis above:

Slight bass shelf around the driver/box resonance region, followed by a rolloff down to 20Hz. Bass sounds even handed due to lack of narrow band peaking. Next-to-wall loading can be seen working as it should.
Reasonably flat through the presence region, with a slow decay at the top end and steep drop after 12KHz.
I’ve killed a little bit of the very high treble with the secondary grilles, but the increased listening comfort at higher levels is well worth the slight penalty at the treble extremities. The frequency response up tilt is gone, and the improvement in listening pleasure reflects the measurements pretty accurately, I’d say.

Not a bad result for a couple of bits of cloth, some staples and a needle & thread. :)

I'm wondering whether this driver would work in an open baffle setup along with a 15". My thinking would be the 15" for the bottom three octaves and the Fane for the rest. MiniDSP should be able to get the crossover region right as well as dealing with any treble peakiness.

Like a miracle cure..........

Let's make a magical speaker, that has only one driver but emulates several drivers.....it must go higher than a Rasta man who's just found his lighter and lower than Corbyn snuffling truffles.

Yet to see one that works........pipe dream.

I agree that single driver solutions are always going to be problematic. Steve seems to have found something that works well for him. A 'FAST' setup (without the sub, but with a decent bass driver) would seem a possible way forward.
