Default Definitive SuperTower Clone - Anyone?

Has anyone done a clone or similar project to a Definitive SuperTower?

Basically, front and rear firing MTM with a side firing powered sub with a passive radiator.

Does anyone own any? How do you like them?


The attached image has some details. Does anyone know what the low frequency design tunnel is (upper right hand corner)? Also, they mention T-Line enclosure (lower corner) but also mention a radiator in the write-up.

Hmm it'd be a fun project to try but there are some risks. You could end up with a pile of useless parts. I'm curious too on why the DIY community does not seem to do bipolar and "omnipolar" designs as much. If such a design was attempted there'd have to be some sort of high frequency and midrange attenuation to compensate for alot of reflected energy. It'd be rather hard to get a flat response IMHO. I own Mirage OMNI-50s they sound great but I have no measurements to back that up. The speaker is voiced with a recessed midrange according to soundstage measurements.

I heard one of the SuperTowers (I think the one with the 5" MTM config). I liked how they sounded. The bass was excelelnt, not too overpowering or heavy. Very open sounding.

Just curious if anyone has tried this type of thing. It is beyound my skill level but I would love to read about it.

Here is an intresting paragraph I found on this website:

http://www.soundstage.com/gettingtec...ical200402.htm

Quote:
"A bipolar loudspeaker is simply a configuration of moving-coil drive units mounted on both the front and rear of a cabinet and wired in electrical phase with one another. The result is very much like having two good-quality forward-radiating speakers wired together in phase with one pointing forward, the other backwards. The loudspeaker now begins to disperse sound nearly 360 degrees around the cabinet. This arrangement produces signals identical to a forward-radiating loudspeaker in front of the loudspeaker with the addition of reflected signals off of the rear and side walls due to the sound produced by the rearward-firing driver units. When these signals are acoustically added together in the listening room, we found that we were now achieving very close to that 30:70 direct-to-reflected sound ratio found in real life."
What is meant by electrical wired in phase??

If you had a MTM configuration, would you just put the same design on the back baffle?

Would you have to add a time delay to the rear baffle?

Just curiously questions.

Have a look on the FR forum. Los of bipoles/omnis.

The Definitive design, being much deeper than it is wide, is going to suffer a significant on-axis bipole dip (a FR dip from the extra distance the sound from the back takes. Lotsa toe-in helps, but best to go wide & shallow.
