Anybody else try these with there HDT cabinets?

I have had much time to think about the PM6A Lowther and it just seems like to much of a gamble.

After reading what Steve wrote:

We don't want to employ the "alternate tuning tweak" into production on the HDT's because it's simply a tweak and it eliminates the option of using different 8 inch full range drivers, like the lowthers, audio nirvana's and so on.

I am inclined to try the Audio Nirvana's while my one HDT cabinet is still stock. One cabinet will be the HDT FE206E alt. tuned and the other will be stock with the Audio Nirvana's. At $118 dollars a pair this seems like a no brainer or at least something to try in the interest of others as well.

Corey, btw, while you're in there mucking with things. I recommend putting a piece of deflex behind the driver.  It's awesome material for removing cabinet reflections (ie, back into the cone). You can get a piece of it from Madisound for $11 big enough probably for two speakers.

Brad,

Thanks for the idea.

Mike,

Just be sure to give both drivers (and passives) enough time to fully break in before passing judgement.  In any event I'm sure the outcome will also be affected by your associated equipment, not to mention your tastes.  I'm sure I'm stating the obvious here.  ;D

I was thinking in the "V" section right behind the driver between the oval cutouts. Yes, its a fairly small area, but very close to the driver. Also putting deflex on the back of the driver magnet might help a little if you have extra deflex.

It could be none of this makes any audible difference. But me thinks the experiment is worth the measly $11

Then again that's a 12 pack of cheap beer. You make the call.

Thanks Brad. I am not afraid to buy the Deflex AND the beer.I consider the beer as a neccessay material cost.  ;)

You're cutouts seem smaller than mine. If it isn't too much bother could you measure the oval for me to compare. From furthest points would probably be the clearest way to describe the scalloped oval.Perhaps I drilled the holes for the scallops to the outside of the template instead of the inside .???
Anybody else have this measurement handy?

thanks,
John

I have serious doubts about that quote from Steve.  The original design and tuning for this cabinet was for drivers very similar to what the MK-II has in them, which are very different from the FE206E and the Nirvana's.  Now if the alternate tuning made the FE206E sound better, it's logical to assume it would also make a driver with similar (almost identicle) spec's sound better.

I may have to follow your lead here Corey, and try the Nirvana's out in my (alternate tuned) HDT's. [/quote]

The alternate tuning tweak on the HDT's lowered the port frequencies to take advantage of the higher mass of a gelwaxed FE206EM driver.  The original HDT tuning is FAR closer to the original 1980's design that was a 2-way.  And the original HDT tuning is perfect for the driver that will be used in the MK II's coming out this fall.

Brad,

It seems Deckert is giving us the hint hint of getting our drivers gel waxed if we want to use the alt. tuning.

Considering that it is supposed to open up the midrange and give more bass it seems almost like a no brainer to have it done. Did you have any reasons why you were not getting yours waxed?
