Greetings fellow Neo fans,

I am buying the fully loaded (upgraded caps, wire, posts, No Rez, yada yada) Neo-2X kit from Danny.  I plan to build the kits as sealed speakers (no port) using a set of PE cabinets to get listening quickly.  If I really like them (and I am sure I will), I would have a more substantial and upscale set of enclosures built and swap the speakers over when the new enclosures arrive.

That leaves me with an extra set of PE enclosures with pre-cut baffle, No Rez, and Vampire binding posts pre-installed.  I thought there might be some interest in this "used" set of boxes by someone else considering the Neo 2X.  Since I am not wed to a particular finish or shape (as long as it is a 0.5 cubic foot enclosure) I wanted to gauge popularity to increase my chances of resale.  So what cabinets do you like?

Thanks in advance for your input.

Update:

So far, with a small sample set, we have all the colors represented and a slight preference given to the curved cabinet.

It is interesting to see what everyone is considering.  I am surprised there aren't more that are thinking about non-PE boxes.

Thanks for the input!

A reminder regarding the curved side PE cabinets:  Danny noted that they are quite a bit less than .5 ft^3, so would be suboptimal.  If PE has new, larger curved cabs, like they told Danny they were going to order from their cabinet supplier, then they would be fine.

I didn't vote because I would build my own cabinets, probably with a 3-D veneer (Anigre, Makore or Sapele).

Hank,

Thanks for the feedback.  I'm glad you mentioned the concern over the interior volume of the PE curved cabinet.  Personally, I was shying away from those for that reason, thinking that if the straight-sided cabinet was closer to 0.5 cubic foot optimum, it would perform slightly better.

I thought you would make your own custom cabinets, that's why I included an "other (floor standing, ported, custom, etc.)" category.  That probably wasn't as clear as it could be.  I guess this is why marketers test their questionnaires.

David, may I hijack your thread for a related item?  I didn't want to start a thread just for one post. 

Recommended changes to the driver holes:
1) Make the tweeter recess diameter 5.125" rather than the plan 5.11" (typo?).  5.125" is a good fit, and it's a Jasper jig setting.
2) Make the tweeter recess depth at least .25" (I now use .26") rather than the plan .24".  That ensures the woof flange will clear the tweeter faceplate.
3) Make the tweeter through-hole diameter 4.125" rather than the plan 4.0".  That makes for less filing of MDF to clear the tweeter-to-faceplate attachment screws and frame.
These mods are the result of my doing 4 baffles so far.

Now back to your friendly pollster.

I've built several speakers in the 0.75MT and 1.0MTM PE curved side enclosures. I was concerned about the internal volume so I posted a message on the PE forum, and the response I got from PE is summarized below. Has this changed? Where can I find the new external dimensions and their claimed internal volume?

Hey Fred,

If you followed this thread on fixing the PE boxes: http://www.audiocircle.com/index.php?topic=54352.0 You can see some conclusions.

I really don't know about the other boxes as I just checked the advertised .5 and .38 cubic foot curved boxes.

The just of it concerning the .5 cubic foot boxes is that after I posted about the problem originally the depth of the box magically increased by 1". I don't think they ever corrected it on the web site, but have not looked into it further.

It is the newer deeper .5 cubic foot box that they now claim to be .477 cubic foot. By my measurements the 1" of increased depth should increase the volume to close to .440.

I did not follow up with them to see if the .38 cubic foot box get deeper as well. It could very well have.

For a definitive answer, someone should brush the interior of one of the .5 ft^3 curved cabinets with polyurethane, let it dry, plug the terminal jack holes and then fill the cabinet full of water with an accurate measure, like the graduated cylinders we used in high school chemistry (yuck) class.  THEN, PE could make a decision to have the cabinets made larger to actually have a .5 ft^3 volume (or not ).

Hello,

Can someone build me a pair of Neo 2X's built to Danny's spec (PE enclosures) with all upgrades?  I have the LS6 in my main system right now (easily the best sound I've heard under $10k retail), but I'm moving, and I'll have a dedicated room for them (15 x 15 7", bigger than what I have now).  So - the living room (50" plasma, 5.1) needs a new set of front speakers.  I think the Neo2x would be perfect.

If you can help, please send me an email at hifitodd@gmail.com

Thank you in advance!

Make life easy hank and use sand. 60 cups ~ .5 cu ft

David, if that's correct, then Kudo's to you for a good idea.  Now, who's gonna invest in a pair and actually do it?
Maybe pbrstreetgang??   hmmm??? aa

[pbrstreetgang]

Haha, we used to do it for custom fiberglass car audio stuff to determine the volume. If I do a pair of 2X then I would want YOU to make a floorstander

Couldn't you just put a large garbage bag in the enclosure and fill that with water?  Wouldn't the weight of the water push the bag into the nooks and crannies?  It did with waterbed frames.

I'm not sure I'd ever get all the sand out of the enclosure.  Then the highs would sound gritty.

rimshot  "Gritty" highs - ouch, what a groaner!

Do the water torture on a scale.  One-half cubic foot of water weighs 31 pounds.  (Will 31# of water in a speaker enclosure blow out the sides?...keep sponges handy.)
