    I have a pine chest that was finished with shellac. I think it looks really good. As for the sheen, if you use steel wool as mentioned earlier, it should result in an even, satin sheen.

      I know its too late for this tip, but when I recess a woofer that has the gasket on the front I like to take the top layer off (the smooth black stuff) remove what is underneath down to the basket, then glue the top edge back on. I think it makes front gasket drivers a little more bearable to look at!

        Ha that would've helped a bit, but I don't think these guys look pretty underneath the gaskets.


        I gotta say I don't find these as easy to listen to as I thought they'd be, the mid range dip before the rise back up around ~3-4k with a wide hump that goes on for a bit, I find it makes them kind of bright, EQ'ing that bit down with two filters (6.5khz -3, Q=1, 9khz -1db Q=3 ) makes me very happy. The result being the speaker is pushed more towards neutrality in it's tweeters response, you gain all the usual benefits so give it a shot if that's your thing, the improvement on how they render space is great. I am using them nearfield fwiw, unsure how these filters translate to mid and far.

          You might like these. A bit pricier.

          That's interesting; I don't find them at all bright, if anything they're a little laid back compared to our other 'reference' speakers. The room has mostly hard surfaces, too.

          Depends on the source material, too of course; ours is mainly 60s-90s jazz, classical and pop/rock.

        Outdoor measurements, wonder what that peak at 2.5k is from? Should've measured the drivers by themselves. It's in different spots of the woofer so I wonder if my xover parts have some variance. Woofer seems kinda ragged, There's two deep and narrow dips at just above 1k and at 500hz that are smoothed out, port resonance?

          Did some solo driver measurements and the peak is woofer break up. A steep active filter help knock it down, I'm curious if it can be done passively in a similar fashion to the amiga xover? I might measure the drivers and import in vcad to toy with, if anything for learning purposes.

            Been toying with xover modifications for this speaker, to try and fix the overall brightness and lack of mid range. I guess this kinda goes against the speakers design, but I just don't gel with the reduced mid range. I was mostly toying around in vcad with some in room measurements to see if you can even modify the current xover components to get closer to neutrality. This is promising enough to me to want to take them outside to measure for some more accuracy. I think these drivers can be integrated a little differently. The xover point was moved down a bit, I assume the tweeter is fine as the hitmaker has a similar xover point.

            I'm debating whether to buy a few components to try my modifications, or just grab a wondom 4 channel dsp amp and just terminate the speakers with NL4 speakon.

              Putting the measurements aside for a moment - and of course, they're important - the DC160 has its limitations as a driver, which Paul notes in his excellent write up. For example, its mid range isn't up to its smaller brother the DC130, but then its bass goes deeper. So perhaps there's only so much tweaking to be done to the DC160 to try to deal with those limitations?

              Measurements at this stage are several orders of magnitude more valuable than subjective opinions on a driver. I'm not really seeing anything I should worry about in the mid range. Flatter response is flatter response, distortion doesn't increase on either driver, impedance is nearly identical, and directivity barely changes. All signs point to a better speaker.

            Maybe it's time to design your own.

              I have a few of my own I'm working on, but these are built in box and just some minor tweaks appear to improve the drivers integration so I have no problem spending a small amount on the parts. This is also fun for me so there's that.
