All, My speakers have decent seas Tweeters and sound fine but when looking at the wilmslow audio site I noticed that scanspeak and higher quality seas units look like a direct fit size wise and are pretty low cost compared to say, new speaker cables. I assume that this might be a decent upgrade and I wondered if dropping in say scan speak revelators is a simple swap or do I need to play around with crossovers etc? I have noted that the tweeters seem to have similar specs and hoped it is as easy as it looks. Advice would be welcome.
