    Re: Lithium

    The rolled Ultratouch from Home Depot says it's 2.5" thick. When unrolled, it's closer to a compressed 1". It has similar absorption capability as OC703 fiberglass or equivalent density rockwool. $6 each roll, free shipping with a box of 6. Great stuff to use (no pun intended).

    How thick is the Denim stuff? I have 1" Sonic Barrier on hand -- that's why I'm asking.

    Somebody's gonna get these for Christmas from Santa

      Re: Lithium

      Fastbike is on the money with his explanation. It winds up about an inch thick after unrolling it and it works very well. I think Sonic Barrier would work out fine, too, if you have it on hand.

        Re: Lithium

        Thanks, Larry. That is a good deal.

        I had a chuckle when I looked at the ad -- two little kids hugging the insulation (don't try that with fiberglass...LOL).

        Just a couple observations - it says R8 and 2" thick on the package. I'm guessing, however, that this is exactly what Scott used.

          Re: Lithium

          I had to do some double-checking - the stuff I have is actually R8. I have a piece that is unrolled and has relaxed out - and it is about 1 1/2 inch thick. Rolled up, it is about an inch. I actually went for the same deal - 6 rolls for $36 shipped. Each roll is 16" by 48". The insulation is huggable as long as you don't mind blue lint.

            Same stuff.

            I don't know where you guys get 1.5", as the stuff I have is about twice as thick. You can peel it into 2 pieces for half thickness if you want.

            I can tell you from experience that anything fancier or significantly higher voltage rating than the Dayton's may give you an issue with fitting the crossover in the cabinet.
            That sounds like something I would do! :D FWIW- the PulseX or Jantzen Z-Standard (if you want to spend for them) are actually more compact than the Dayton caps are for the same values. This could help in cramming it in there.

              Re: Lithium

              Doesn't appear to be necessarily the same "stuff" to me.

              Might be same sort of material but the HD stuff appears to be the better bargain, especially if you buy 6 rolls and get the free shipping. I put an equivalent "weight" of Meniscus Eco-core in my cart and with the $17.65 shipping it came out to almost $58 as compared to $36 for the Ultra Touch Denim. I'm no insulation expert....just a cheap bastard.

              Somebody please check my math.

              EDIT: The Ultra Touch also states R8 value. Anyone know what the Meniscus stuff is?

                Re: Lithium

                Okay- I was thinking they were more similar than that. I've used the EcoCore and like it a lot. I may have to take a trip to HD to find out...

                I do know that UT comes in 2 different forms/quantities/cuts, so that may be the issue.

                Other than that- use the Bamboo Nature-Fil from Jo-Anns. I like it alot! Click image for larger version

                  It's an "online only" product AFAIK, but I'll tell you what. I will send you a roll since I'm getting the 6-pack. I get a lot of things in 6-packs, save for my abs. ;)

                    Re: Lithium

                    I remember seeing it on the shelf at my local HD at one point in time, and only some of the locations stock it where others do not- or so I've been told.
                    Maybe they stopped carrying it in-house.

                    Cool! I appreciate the chance to try it out and be certain.
                    Thanks!

                      Re: Lithium

                      That's the stuff. Going from memory w/ my old brain. Cuts easily w/ shop scissors. As Wolf says, you can peel it for half thickness. Spray adhesive works great.

                      For Wolf: Us guys get 1.5 " because that's what it measures. Meniscus may have the same material but in different sizes. Looks like they're stocking the typical home insulation batts designed for 16" centers and cutting to order.

                      Very satisfied with the stuff. Need to get some of the Nature-Fil to try as more general stuffing. I have used the Ultratouch more as lining than stuffing.

                        Scott,

                        I'd like to hammer out a pair of these for KY. Have a few questions though.

                        Can you provide driver spacing measurements on the baffle?
                        Did you do any internal bracing? And finally where did you mount the port on the rear baffle -- tweeter height, centered??

                        Thanks.
                        Bryan K.

                          Bryan,

                          The port is centered on the rear baffle at tweeter height, as you suspected. The cabinet is 1/2" baltic birch with no bracing. Baffle layout is shown in the attachment.

                              The Lithiums will work well for that application. The primary advantage of the Nano Neos is extra bass extension (if you consider having a 4" woofer trying to play 35 Hz an advantage), but they are more than twice as large (by volume). The Lithiums are designed with nearly full baffle step compensation, which means the bass will still be satisfying at lower levels. The Lithium's measurements indicate that the midrange will be smooth and well-balanced on and off axis and that the drivers are well integrated. There have been some concerns reported about the Nano Neos in that regard. I don't think the two designs have ever been side-by-side for a comparison, so I don't really have any way to say definitively what differences to expect. I can say that I am confident that you will be happy with the Lithiums for low level listening. Since I built them, I haven't heard anything at their size or price point that I would want to trade them for. They have been to 3 DIY events in the past year, and I haven't really heard any suggestions for how they could be improved, although I would happily accept any input that could make them better.
                              Keep an open mind, but don't let your brain fall out.

                                Having heard both these designs and building the Neos, my nod goes to the lithiums. Scott, you did a helluva job on these. My only recommendation it's to add a sub for that last octave if you really feel it's missing.but in the near field I wouldn't bother.
