The not so pretty looking items in the picture above are a pair of point to point LSi15 crossover built with all film caps and air core inductors. The tweeter inductor was the only piece carried over from the original LSi15 crossover. The mid and woofer caps are Dayton film, tweeter caps are Sonic Caps, mid and woofer resistors are regular Mills, and the tweeter resistor is a Mills labeled MRC-50 resistor. I used the metal cased Mills instead of the traditional Mills in this location because it has less coloration, it's almost as transparent as a Duelund(IMO), and it can take a real beating. The mid and woofer inductors are Solen Hepta-Litz type, they were chosen since they had almost identical DCR's as the original inductors. I normally like to use solid core or foil type, but they would have thrown the speaker's balance off.
Now for a little background. When the LSi15's were originally dropped off at my house, the owner and I gave them a quick listen. Our impressions of them was a little disappointing when compared to the custom speakers I also had set up at the time. Bass was boomy, mids congested, highs veiled, imaging was so so. So instead of just upgrading the caps, we decided to go all out.
It took me a little longer than expected to get everything together due to work, family obligations, and nothing going as planned with the upgrade...but fortunately the owner was very understanding, and even more so, they should easily exceed his expectations.
Initial impressions, from a cold start there was a huge improvement top to bottom. They no longer sound veiled, everything is much more fluid and airy. Highs have a little more sparkle and will improve more with break in. Mids are no longer congested and are much more coherent. Bass is surprisingly is less bloated and better defined. As a whole, the speaker is more dynamic, coherent, smooth, and no longer sounds restricted. Imaging and soundstage has improved somewhat, so far. The center image is very well defined, overall imaging and soundstage is better, but will open up with break in. I only wish they would dig a little deeper, but there's only so much a small side firing woofer can do.
