[quote user="jessie.dazzle"] Resonant frequency :
I did not try to measure it. Can anyone confirm the following : I assume this parameter is most easily determined by playing a series of tones at constant signal strength (volume setting) whi...

It is an opportunity to pursue the common obsession with all things military: the largest formed transparent structures are probably fighter jet canopies. Acrylic would be optimal, vacuum formed at elevated temperature. Were Jessie dazzle still here ...

[quote user="jessie.dazzle"] I have from time to time listened more with a very crude sort of injection channel plugged into the system.
With this device, it is obvious that compressed recordings are more tollerable...My waf also noted the effect. ...

[quote user="jessie.dazzle"] Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling... I woul...

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

[quote user="jessie.dazzle"]No, I did not change the wires, just took the photo of the old socket from a different angle (off 90°); you need to mentally rotate the image.[/quote]I did mentally rotate it. The very first wire on right from the bridge b...

Hi Romy:See below an interesting approach. It probably violates some of your axioms but it does seem rather promising methink, without having heard it. Maybe Jessie Dazzle knows about these and could give us the lowdown as they seem rather close to ...

[quote user="jessie.dazzle"] If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have o...

[quote user="jessie.dazzle"] This event really reinforces my curiosity to try such drivers in the Mid-Bass horns. As there are plenty here in Europe, that is exactly my plan (most however are not 16O... don't know to what extent that might be an issu...

[quote user="jessie.dazzle"]To my understanding, taken individually, your attic horns would be more obviously working in a half-space environment. For any output that is common to both the L and R channels (some in the case of stereo recordings a...

[quote user="jessie.dazzle"] For a lot of reasons, I'd vote for an alternate placement. You've got that basement, so why not use it as a rear chamber? You might be able to use the volume "as is", without building a proper rear chamber. In this ca...

[quote user="jessie.dazzle"]Romy, I'm very pleased to learn that you've got your Injection Channel done. I assume the above illustration is not indicative of the way you have the Tannoy Red aligned with regard to the other drivers, as it appears to b...

[quote user="jessie.dazzle"] Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may ...

Sure, contemporary polymer concrete can be made suitable for speaker enclosures or horns. Its biggest sonic benefit is that the material itself is fairly non-resonant. It's just a bitch for a DIYer to make one after another while experimenting with s...
