Small monitor- made in the states

Tpdoc - Mike is retiring and ACI is going out of business. Good speakers and subs though.

BTW, I didn't think of him because you said "on a shelf" which wouldn't necessarily consider to be optimal so this may be moot, but then you're talking about a sub. You don't mention a budget either. If you really want to kick some very serious high-end butt with a monitor/sat system made in the USA, definitely do not miss Duke Lejune's line of Audiokineses speakers. His Planetarium system is amazing! I would definitely put it on my short list if Duke tells you it can work in a bookshelf. Not exactly small, but let me tell you, that system is taking names! Aside from the Planetarium system, I've only ever heard his much larger speaker, which is also VERY impressive but larger than you'll want. Highly recommended with no reservations.

Please do yourself a favor and try or at least research the Silverline minuet. Made in the USA, small, affordable, easy to drive and sound great.

Hmmm, I'd agree that Alan Yun makes wonderful monitors, but I don't think his stuff is made in the U.S. They may be assembled in CA, but I'm pretty sure his drivers are sourced elsewhere, and the cabinets are actually made elsewhere (read: overseas). I could be wrong, but you might want to check into that if that's your criteria for buying a monitor. Of course some aspect of any of the products recommended here may also be actually made overseas and assembled here as well. It'd be pretty difficult to buy any electronic gear tthat is purely U.S. made inside and out.
