  • New Horizons With Larger Cabinets?

    Re: New Horizons With Larger Cabinets?

    Just build the Nano Neos. Flush mount the Tweeter. A 45 mm Forstner bit will make the outer cut for the flush mount. A 1 1/4 Forstner will make the hole for the tweeter.

    The Nanos will play low enough as is (around 40Hz). If you don't want to stand mount, go ahead and make a tower. Create an inner compartment the size of the original Nano Neo design. Mount the crossover and input terminal in the lower "empty" section.

    There is also a Neo MTM design that has a build thread. Chris provided a crossover design for the MTM build in that thread.

      It is possible. The ND-105 is very versatile, and it behaves somewhat well in a larger cabinet. Remember though, with extended bass, comes less power handling and unloading of the little guy. It was why I chose the mix of size and extension (amongst other reasons).

      I am unsure how much deeper you need to go. the NH'es play to the mid low 40's with little issue, and are safe at volume as demonstrated at DIY NY/NJ. Even with the bass drum of Copeland's "fanfare for the common man."

      I would be willing to model into a tower for you if you are serious about the build. If so, please PM me.

        can you TL load it in to a tapered pipe?

          Hey Roman,

          While I hear from the board there are some great ones out there, I have yet to hear a TL I like. From what I read and play with, I do not like the sacrifices to make a TL perform as I like.

          Admittedly, I have only played with a TL design once or twice, and since they have never grabbed my interest, I have not studied up on them. But I would not doubt some of the resident TL experts could make it happen!

            This has been said before, but you should think of these little guys like they're a fairly stout 6-1/2" woofer, not a 4". I don't think I'd ever recommend mounting these on the back side of a 3/4" baffle (and I don't recommend using anything lesss than 3/4" material for the entire box, again, think 6.5" woofer). It SEEMS to me that working through almost the entire vocal range (up to 4k), that putting them behind a 3/4" baffle could make them a bit "shouty".

            Now, it might be OK if you open up the front edge with a chamfer or roundover, but I still think you'd be hurting dispersion. It would probably be OK if you put a "cosmetic" panel over the front, like 1/8" masonite, to hide the 105's pincushion frame.

            FYI, the lip on the ND20FA-6 looks to be about 1/16" thick (a lot thinner than a standard dome faceplate), and the surround on the 105 sticks out about 1/4" from the frame. It would probably be acceptable to cut the 105 into the baffle 1/8" (even though the frame is pincusion, you could drop it in with a round recess cut), surface mount the tweeter, then cover up the woofer faceplate/screws with 1/16" aluminum plate, cut tight around the tweeter opening. (Just babbling.)

            I DID design a Nano Neos MtM box to go with the XO. hyperlite needed a specific sized/proportioned box for his special ap., so he altered the box, driver layout, and ports to suit his needs.

            IMO, the Nano Neos MtM will most likely give you about the same bass presence and reach as a fairly good 8" design, although I've never heard one.

              here's the in room response of my new horizons, full range, no eq, from my listening position (they're pointed straight forward, so lp is slightly off axis). realtrap's modecalc confirms that the huge peak at 48hz is a room mode. as you can see though, even if it weren't there, they play plenty deep for most intents and purposes.

                One easy way to hide the driver screws is with a sheet of "craft foam" and some lightweight glue (even low temp hot melt). 1/8" thick, comes in a variety of colors. Do a slightly recessed "old school" baffle (inset a 1/4" or so) and you'll have a lot of disguise options.

                  The OP was talking about flush mounting from behind the baffle. I take that to mean that they are recessed into the baffle at least 1/2", using some type of reinforcement for mounting. I agree that this is not an ideal solution for a relatively minor (to me anyway) issue. As you say, a thin false baffle is probably better if the esthetics dominate.

                  I don't remember hearing complaints about the looks of the New
                  Horizons.

                    LOL - you guys seem more concerned about the flush mounting than anything else, I guess that means changing up the enclosure volume and port tuning shouldn't be much of a concern, then!

                    As far as flush mounting goes, whatever I end up doing won't have the woofers flushed below the height of the surrounds, I'll likely have the surrounds still protruding slightly if possible. "Recessing" the woofer into the baffle by less than 1/4" will likely be the goal, similar in proportion to what a normal woofer's frame would present around its surround.

                    The original New Horizons had a design intent of a backwards tilt via the base spikes for phase alignment if I remember right... I wonder if recessing the woofer will "add" to this requirement, or whether reversing the phase of the tweeter would take care of it?

                      Whats going on above 2K? - does the tweeter need less BSC?
                      I may build a pair for my home office desktop - so i was wondering about this anyway.
                      Could it be normal unit to unit variations?

                      BTW - I was one of the NYDIY attendees. The Horizons were the first and among the smallest speakers we heard . This was in a BIG room (guestimating 20 x 60 w/ 12 foot ceiling) and we were collectively stunned at the bass. Some thought the room might be exaggerating the bass - but I felt it just let it "breathe" in a way people were not used to (the smaller the room, the more serious the peaks and cancellations)

                      OTOH we kept our SPL levels sane - maybe upper 80's. Personally, i wouldn't get greedy with a 30W / xmax=4 / 82.6db SPL 4" driver
