#6 XMechanik Mechano23 DIY: $200 per pair DIY parts Madisound (Tweeter) Madisound (Woofer) eBay

Pros: The bass alignment is unusually well damped, with a measured Q of 0.336, among the lowest of any speaker in this catalog, so the -3dB point at 77.6Hz rolls off cleanly instead of building into a resonant bump the way many small ported designs do. On axis deviation measures a tight 0.195dB average, and Audio Science Review’s independent Klippel NFS review called the predicted in room response nearly perfect, with directivity matching that beats some commercial designs costing many times more, all from about $200 in parts. Measured bass extension of 77.6Hz (-3dB), with a measured sensitivity of 85.1dB.

Cons: This is a true DIY project. There is no assembled unit to buy, drivers come from Madisound, the crossover kit comes separately from EZ Speaker Solutions, and the birch plywood cabinet has to be built and finished by hand. Listening window smoothness measures a moderate 0.47 and the sound power directivity index has more variation (standard deviation 4.02) than the tightest speakers in this catalog, so off axis energy isn’t quite as evenly controlled as the excellent on axis figures suggest.
