yup, i have virtually no staining skills as you can see overlaps and varied light/dark areas.
i sanded 220, 320, and 400 grits after each coat of shellac. it's very smooth, but could use a few more coats/sandings.
they sounded really nice, the vocals/highs were very clear. i think i need to listen to the mid bass a bit more as it seems a bit lacking. maybe it needs to break in a little, or it got overpowered by the 15" sub. i have only listened to it for about an hour.
"....meaning the cross-section of the horn is exponentially proportional to its length. These have long, narrow throats with ever expanding mouths. The advantage of this kind of horn is it tends to have large bandwidth, providing a good acoustic load at both high and low frequency. One can expect an exponential horn to provide adequate SPL, even response and low distortion over its passband.
The problem with an exponential horn is it tends to beam at high frequencies. As a result, only listeners that are directly in front of the speaker will hear high frequencies. ......"
Are you using the Radio Shack SPL meter? It's not very accurate up high.
I couldn't find my econowave measurements, but I found it for another set of speakers (CV factory, not DIY) and they rolled off big time right at 10k also. I used the digital RS meter.
