I would really like to get the best low end I can out of the Neo 2X and avoid a sub. You said most of the PE & Madisound premade cabinsets are too wide. Are you aware of any other pre-made cabinets that would work or am I looking at building my own?

The biggest thing stopping me from making my own cabinets is the veneer but I am also short some power tools, mainly a router.

Check with Hank (he posts here all the time), he built a pair of speakers that is a discontinued kit that I designed for Raw Acoustics. It uses the same woofer in a floor standing version (-3db at 40Hz). The only difference in that design was that it used Al's ribbon tweeter.

I am sure he wouldn't mind building another set of them for the Neo-2X kit. He has built cabinets for my customers in the past. He enjoys doing it and does a great job.

Thanks. I will look for Hank's postings and get in touch with him. It looks like he does a great job.

I did a short review here on those very speakers of Hanks and was very impressed with the build and sound

I'm interested in a pair of Neo-2X as well, so if anyone wants to build out a pair and sell them to me, please send me a PM.  I don't have the time/skill/space/equipment to build anything myself  :lol:

Hi Danny -

Looks like just what I'm looking for, if I can find a kind soul to do the baffle for me. 

One question, however.  Given the somewhat smallish size of the PE cabinet, have you given any thought to stuffing the box, or, perhaps some type of aperiodic design?  I'm thinking of a short, stuffed 3" or so port tube in the back wall. 

Order by phone or email?  I don't see this one on the website.  Thanks - Pat

1.0 cubic feet is the optimal ported enclosure for the M-165X woofer.

Most of the prefab 1.0 cubic foot enclosures start to get a little wide though. That will add surface reflections which will disrupt the response and restrict imaging.


Dayton MTM-1.0BK 1.0 ft³ MTM
Dimensions: 22" H x 9" W x 13.5" D.

How much wider matters? I see this one is listed at only 9" wide, versus your plans for 8.5" (and its flat so no expectation for misinformation on volume, correct?). Is that enough to throw it off?

Hello Danny, have you ever heard the very small x-sub from av123?  If so, do you think it would be an interesting combination with the Neo-2X for music in an apartment (i.e. low volume)? 

Thanks

The X-sub should work just fine at low levels, I think it goes down to around 28 hz or so cleanly....plus, there's a nice sale on them right now.

I always recommend stuffing the box. For this one I'd recommend the sealed box or a 1.0 cubic foot ported box, and I'd line both of them with No Rez and add additional damping via fiberglass insolation or poly fill.

Either is fine just don't e-mail me your CC info (for your own safety).

It all matters (to some degree). Any time a baffle gets wider than it needs to be it adds surface reflections that will not be wanted. A little wider (like a 9" wide baffle) won't be too bad but not as good as it could be. It would be on the order of a minor change. Some may not notice it. Some may only notice the difference if comparing two of them.

I designed that one for them.

As long as you are not needing a lot of volume it will work fine and is a good sounding little sub. They are really hard to beat for the money too.

cujobob, here's how it works:  you order the kit from Danny, he ships it to me - you order the cabinets from PE (unless Danny does a group buy and has cabinets drop-shipped to me), I assemble the crossovers and install them and the drivers, plus line the cabinet with No-Rez (if that's the product you want), then I'll burn 'em in for several hours, then ship to you.  You pay me for my labor and actual shipping cost to you.  I'm doing that for someone now - received the drivers and xover components from Danny - I'm laying out the crossovers now and waiting for the cabinets to arrive.

Trafford, my cabinet design for RAW is pretty complex - lot's of internal braces and it's a slot port design.  Translation:  lots of man-hours.  I'll see if I can post one of my CAD file drawings on here - can anyone tell me how to do that?

Hank,

I would appreciate any cabinet drawings you can provide. I will have to decide between building or buying the PE cabinets and hoping for the best. I can appreciate Danny's comments about getting the most out of his designs by having the 8.5" wide cabinets. I am not too worried about building the boxes. I am a bit concerned about routing for the speakers and very concern about doing a good job with the veneer. These speakers need to look nice to get the approval of my better half.

Why use stuffing?

How much stuffing is enough?...is there a rule of thumb?

How much stuffing is too much?...what happens to the sound?  (Or, the sound of not enough stuffing?)

The stuffing is used to absorb the back wave (sound) and keep it from passing back through the cone after bouncing off the walls of the box.

Too much stuffing restricts the flow of air through the box and changes the damping on the woofer.

Too little stuffing and you hear the reflected sound energy from the box.

Trafford, I am clueless as to how to post an AutoCad drawing here.  If someone can walk me through it, I will.  Also, I can't post construction photos.  I hit "copy" on one of my photos, but when I try to paste within the thing, "paste" is light grey and won't work.  Anybody?

Hank,

You need to load the pics onto either AC gallery or some other picture hosting site like picasa, photobucket etc. And then type the link to your pic within the "IMG" tags here.

Hank,
Adding to what Cacophonix said...
First, right click on the photo a few post above this one and choose "Properties".  You will see the web site it came from, but more important, Dimensions.  400x266 is probably the smallest,, but for line drawing would probably want 700x900 or so - readable without overwhelming the screen and still a small file.

That said, I personally use photobucket (didn't like Google's picassa as seemed like wanted to take over all photos on my computer and I uninstalled it).  Photobucket is free, upload the photo then use the edit function to resize it.  Caution, when resized down, can't resize up and have to re-upload the original if you resize too small.  The nice thing about photobucket, it gives you a choice of 4 variations of the photo address for intended use.  In this case, choose the "img" variation and a straight paste into the reply.  All the "insert image" icon does in the reply area is insert the "img" tags and you are supposed to past the unaltered/straight photoaddress (first of the 4 choices in photobucket) between the two "img" tags.

Disadvantage? By design, this forum does not download the photo to its server but reads by active link.  Delete the photo or close the photobucket account and the link disappears, giving no picture from that point on.  The same would be true with other photo managemt services like picassa and imageshack etc.

Thanks Cacaphonix and tizeye.  I'll work on it at home tonight.  My son did load a few photos of mine onto Photobucket, so I'll try to link to it.
Meanwhile, for grins, here's a link to my low-rez first attempt at a web site with some of my older work, including Danny's Alpha LS cabinets (back in his mullet days  :wink:).  Two more recent speakers there are generations 1 and 2 of Danny's A/V-3's.

My Neo-2X all dressed kit is on it's way to me!  :drool:  And a nice little AV123 X-LS sub is also on it's way to me, what a combination these will make!   :drool: :drool:

Man ho man, it's not even Christmas or my birthday yet!   :icon_lol:

Thanks Danny!

Could something be used/placed on the baffle to minimize reflections?

Felt can be used. Results can vary.
