Building a PROPER cabinet for speakers is more complex and costly than dipoles, and dipoles tend to throw a more realistic sound stage. I know this from owning Genesis V loudspeakers (to its credit, it did have a rear firing tweeter) Usher 6371s, First Gen Reference 3A DeCapos, a short stint with Nearfield Acoustics entry level Pipedream 6 ft prototype, then moved on to Accoustat 2 + 2s, Magnepan 3.5Rs (and even though they had their own magic, both physically dominated my room. for the last couple years, I have been enjoying Emerald Physics KCIIs, which are as light and fast as the 2 previous dipoles, but the KCIIs bring better bass and more focused imaging, AND, they're super efficient. The amount of wood and the simplicity of assembly is something a DIYer should consider.
