I've got Spendor S5e, Totem Mite, Von Schweikert VR-1, and ProAc Response One SC speakers. They are all very good speakers in their own right. I've used the S5e's and VR-1's in a 14' X 24' x 8' room and they worked fine. I've used all these speakers in a 11' X 10.5' room and they worked well there too -- I've used different amps with them. I like the S5e best. Nice, pleasing, sweet sound with my Pathos Acoustics Classic One MK III and Pioneer 79DVi universal player and Polk Audio XM tuner. Outstanding sound! The bass is quite good for a small driver. I like that it has a separate driver for the woofer, and also crosses over at 4500 hz or something like that. Unfortunately, the low crossover at 700 hz or so, can be heard depending on singer, for example, we watched a Bing Crosby movie and when he sang you could hear his voice jump in frequency range, from deep tone to a bit higher pitch, so not a smooth transition, but abrupt. But other than that, great speaker. I've heard someone who loves piano say they did not like the S5e, so maybe there is a crossover range there too that is audible. But every speaker is weak in their crossover, if you know what to listen for you may be able to find it. I remember the Bose 301 speakers maybe 25 years ago, as they had a crossover range that was long and slow, which they said helped in that regard. I actually liked those speakers.
The Totem's are small, but sound big and still have good bass for their size, and only need maybe 10 watts. Of course, bigger cabinets or drivers give you more bass. VR-1's have an unusual bass loading, I think I heard it's a transmission line, but has a small port on the rear too. The bass is detailed, but not strong, but overall a nice sounding speaker (but can be somewhat analytical or at least the balance can be tilted towards the highs since the bass may not be strong, depends on the amp), and don't need much power either, i.e., maybe 10 watts. The Proac's are quite good all-rounders with good detail and also very easy to drive.
