What is your take on high efficient speakers vs. low efficient speakers?

It's just wrong to think that hi eff doesn't do low bass I have bass horns that can bend doors and make your eyes resonate some I designed are used in military simulators to replicate explosions and gun fire. Just because in your limited experience you haven't heard deep bass in hi eff doesn't mean it's not available. It just means you made major compromises in size.

A noob question.

Will a 12w SET be enought for a 95dB sensitive speaker in a 190 sq. ft room if you listen at low to medium levels?

Exactly, John. I expressed a similar view in my latest post on this thread page some two months ago, but it went to deaf ears/blind eyes, it seems.

It must be said though people don’t need +100cf. behemoths to experience high eff. bass to 20Hz. 21"-loaded high order bandpass subs with 100dB sensitivity will do honest 25Hz from a 16-17cf. volume, and my own tapped horns are 20cf. per cab @22Hz. Even so most audiophiles are likely to bark at such sub cab sizes, and so there’s only so much one can do.

But, I have never heard these systems deliver really low bass at a high level. I just don’t care that much that they don’t do subwoofer stuff and I don’t really like subwoofers in these sort of high efficiency systems. [...]

Which kinds of subs have you heard paired with high efficiency mains - low or high eff. subs (i.e.: smaller or very large subs)? I don’t find high eff. mains pair well with low eff. subs, they just don’t mesh properly. If however high eff. can be maintained across the whole range, another matter - given of course mandatory care taken with implementation. I prefer crossing fairly high to the subs, typically no lower than 80Hz, and with the mains high-passed accordingly - fully actively (mains + subs), if possible. That, to me, offers the best opportunity for a coherent, fully integrated presentation.

If on the other you’re perfectly OK sans subs, all is merry, though if you have yet to experience the right high eff. subs in conjunction with your mains I would say you’re potentially missing out on an extraordinary sonic meal. Pardon, I may be presumptuous..

I like Rolls Royce’s specification of horsepower in the old days: "Sufficient."

Haha, stated with confidence indeed :)

Depends on Co and sound quality.

@simna  With 12w and 95dp  speakers and only 190 sq. ft. room you can most probably  brake your windows in the house.
