O.K. I know this is out of left field, but here goes!World Designs WD25A
- can be bought fully built; a British 2-way equipped with a 10" woofer operating in an aperiodic enclosure (a sort of acoustic-suspension/bass-reflex hybrid)
This speaker is based on the classic Dynaco A25
, an American bookshelf speaker using SEAS drivers sold back in the early/mid 70s that was also one of the most successful numbers-wise American speakers ever sold (collectors and vintage audio enthusiasts like yours truly still look for it in thrift stores). The philosophy behind it was basically the same as the Andrew Jones Pioneers discussed so much here: inexpensive but included lots of clever design features that enabled it to still sound good, much better than its low price would indicate.* Also like the Pioneers, the A25 is also known as a warm sounding speaker, which many feel makes it very suitable for music, particularly useful for the many modern tracks mastered with stupidly hyped upper frequencies and nutty levels of overcompression
They also sell a floorstanding version
with improved bass output.
BTW 10" 2-ways were a common design until around the mid 90s, and sold by many mid-fi manufacturers e.g. Pioneer, Infinity, JBL, Boston Acoustics and (of course!) Advent.
* particularly the crossover, one of the most expensive parts of any speaker: the original A25's consisted of one capacitor, in series with the 1.5" soft-dome tweeter - that's it. This was because the two drivers were made for each other and the woofer's response could be tailored during the design process to naturally roll-off at the correct frequency, and the tweeter used a 1 and a half
inch dome so it could handle more power without the need for a more complicated xover. There are sonic tradeoffs to do this, but for the A25's price most owners didn't mind.
