  • aura ns6 6" woofer

    hey guys! i just orderd 4 of the aura's for a center channel build! the box will be 50.5"x10"h x 6" deep, it will be mounted under my lcd on the wall! just wondering if that is too small for that many woofers with 2 cv 5 cerwin vega horns!?? should i just use 2 ?? what are your thoughts??

    That's too small a space for 4 aura's volume wise you'll need .5 to .75 cubic feet for each driver if you're porting them.

        1.7 cube by my math of those are internal dimensions, 1.07 if made from .75" material. Either way unless you are going to run them full range, I would not port since it is 80 and above for HT anyway. You are on the right track. FWIW, IMHO, et, al, ect.... nuyck nuyck.

          If it is for a center channel keep it sealed and cross them to a subwoofer at 80 to 100Hz. Excellent midwoofer with a lot of emphasis on midrange not so much on the woof part any way.

          I would make it a 2.5 way rolling the outer midwoofers off to just compensate for baffle step and you should better integration with a tweeter. Maybe I am misunderstanding but are planning on using to tweeters? If so I would just use a single one crossed to the inner two midwoofers. This will result in the best integration and horizontal axis performance.

            With light fill sealed it looks like you'd have 77Hz f3 with light fill in that size sealed going for 2 series of 2 that are the paralleled.

              ok! so, my cabinet size , sealed , with one tweeter , 2 woofers and light fill is my best bet?

                current size sealed 4 woofers wire 2 groups of 2 speakers in parallel and then wire those groups together in series.

                    In a 2.5 way there's an added inductor on the .5 woofer forcing it to roll off earlier than the primary woofer but prior to that roll off the two woofers are working together. I general we try to not use pre-made crossovers since better results can be had from building custom crossovers either through taking measurements or simulating from traced measurement of the drivers.

                        There are enough people here who have used these Auras that I'm sure someone might be able to help you out. You will likely need to use a different tweeter because I have never seen anyone here mention measuring or using a CV horn. Not to worry though, you can find nice sounding tweeters for not much money, if you know what to look for. ;)

                          if those are external dimensions, assuming 3/4" material, it works out to 1.03 cubic feet, which is about right for 4 in a sealed alignment, and will yield a -3db cutoff of ~90hz, which should be fine for a center channel.

                            Isn't Curt Campbell working on an MTM Stentorian? Or buy two more and do his Stentorian Center Channel.

                              You get a custom XO, but more importantly, you get the whole design, not just box parameters or XO circuit diagram. Curt's specified driver connections that will keep your impedence in friendly territory, and bass alignment (sealed with vent) that works well with these drivers. Plus, he's been known to respond to questions....
