Hi efficient speaker, bass problems


I know i'm going to take a severe tongue lashing for asking this question but . Is it me , whenever I hear low efficient speakers they don't seem to have a grip on the bass like less sensitive units ? The amount of bass is there , and some have good weight , and punch , but where is the control ?

Boy T M please rewrite your post. Efficency and sensitivity are not the same but not different only opposite. Thus bass is not opposit only different ? ? ?
I am not sure what you're asking. Your title says hi efficient but your post mentions low efficient speakers not having a grip on the bass.

My experience tells me that bass control is a function of the amp, and preamp to an extent. I use very hi-eff speakers and get very good control, definition, and impact from a mix of PP and SS amps.

As to your question, I will assume you meant that you don't hear bass control from hi-eff speakers. I posit that most of what you're hearing is probably due to the speakers being driven by SET or some other underpowered amp. Just a guess.
Tmsorosk, it may be a language issue, but the appearance is that your post is in contradiction to the title of the thread. In addition, your post mentions
low efficient speakers
and then in the same sentence
less sensitive units

so its hard to know what you are asking. Would you care to try again?
Hi Tmsorosk,
As mentioned above by others, control is a function of an amplifier, but there is no doubt that High sensitivity speakers typically show the dynamics and control of an amplifier easier. As far as grip and control. I am using a 86db, 4 ohm speaker, it is fast and accurate. I have had speakers as high as 97db 8 ohm, they required much less amplifier to have the speed and transients that I believe that you are referring to as control.
