Near Full Range, Highly efficient Stand Monitors?


Okay just curious, who builds a very efficient, maybe 95 db or better monitor/bookshelf type speaker, maybe with at least an 8" driver that goes reasonably deep into the 30 hz ranges?
Seems most would be rated around only 45 hz or up, most single driver designs in a small cabinet even vented would not go very low.. Anything? Even down to about 38 hz or so with a stable 8 ohm load, having some actual bass output?

Thanks

Well in all honesty this was more a general question rather than for a purchase, and I would not mind playing with a nice small speaker for fun, but it would need to be pretty cheap.. in the 400 range or so used.. Otherwise its not justified to me to have them as a hobby project or just keeping them around to have for a studio type setup when I want to use them.
Reference 3 A MM de Capos- killer and just one cap as a crossover to the tweeter, biwire/biampable. Huge sound stage.
I have been surprised with the bass out of my Dynaudio Special 25's. Stereophile measured them at 89 db/1w and the impedence is around 6 ohms. They say 15w for a small space. I have to attenuate my preamp due to excessive volume.
