As some of you may remember a couple months ago I finished up some mini voigt pipes that sit about three and a half feet tall and use a single three inch full range Audax HT080M0 driver. So far I'm enjoying these speakers with their smooth highs, subtle bass presence and sweet midrange. I would like to do any tweaking (or anything major) before I paint them.
With all the sweet luxuries that come along with a full range speaker I'm still lacking something. These little three inchers lack punch and impact. I have noticed some music sounds amazing on them, while other music just doesn't do it for me. I threw in Michael Bublé's cd and played the song 'Fever' and was just astonished at what these little things could do. Next cd was Dido - No Angel and then then dissapointment set in. It just simply didn't have the midbass that really makes it envolving. The highs were great and they image very very well but overall they just didn't cut it.
Now to the question ~ Am I just asking too much of a three inch speaker or is there some tweak I can do to try and get them to have more impact and become an involving speaker?
Okay feel free to skip this part as it's just more background information that might help.
The enclosures measure out to about 0.2 cubic feet, ported at the bottom and were built to be tuned in the area of around 80 to 90Hz. As I've graphed them in room they roll off ±3dB around 55Hz but have nulls at 180-190Hz and 280-320Hz. Maybe these nulls are hurting more than I had expected. The top half of the speaker is stuffed with a decent amount of polyfill.
I'll try to graph them again tonight to see what's changed in the last while. Maybe I can push them against the wall some more.
FWIW they're running off a NAD integrated amp (c352) and a crap toshibia cd player. I've tried them with and without my sub. The sub helps with the overall presence and soundstage but it doesn't add enough of that impact I'm looking for.
