Actives do seem to becoming more popular, so plugging into mains, is really a must. The giant vintage speakers - only seen one thread on this, and did let me know about compression drivers, which I was not aware existed. With DIY, these are interesting, as new suppliers or modules are always interesting, and can allow you to save money, and help others start up a business. We need these type of additions to keep the discussion diverse and interesting, and I have not really seen that many on DIY. Not seen a dedicated thread to DIY, but there may be one recent.
I enjoy reading about other brands that are not mentioned in the hifi press, just to balance the perspective on what is possible and available.
