  • 6 woofers vs 1 - fair fight?

    Which would you choose given that you are looking for dynamics, detail and low distortion. Size, form, sensitivity and implementation is not important (but will be allowed to follow function a required), lowest of the low will be handled by bigger woofer(s).

    A state of the art - like the scan speak 18W or 18M for around 212-218
    or 6 of a pretty good driver like the Peerless PPB 830874 currently on sale for 35 for a grand total of 210

    So, for a very similar budget in drivers, which would deliver the goods, 1 pair of SS 18W/M or 12 of 830874 or what be the advantages / disadvantages of a short array vs a SOTA TM?

    The array would have the woofers sharing the load, whereas the SOTA woofer would have to do it all itself. Depending on your goals, both would be up to the task, but the multiples would likely have lower HD via sharing the load.

      A little oranges to grapefruit comparison. Depends on environment, configuration and music choices. That's just a start.

        6 woofers per side Ani? That would be a fairly large speaker (~3 cubic foot towers).

          not really, the 830874 are pretty happy sealed in 10 liters each, so about 2cuFt, of course the SS would be happy sealed in much smaller enclosure. But even then 4 per side should be good enough. But just an thought, as I was looking at sale items. The 4/6 speakers can also play pretty low boosted in a sealed cabinet. But the single SS can also hit pretty low all on its own, but also needs a significantly bigger vented box.

          Hence, removing the box, boost etc out of the consideration. Given that budget is always limited, would quantity be able to catch up to quality? budget here refers to driver budget, not box (which would be significant or XO or active, etc).

          Ben makes a good point about distortion, since multiples would be lower distortion, given that the 6.5 PPB is no slouch to start with. But back to Kenny, what sort of music would be suitable for each type of speakers.

            Well, you would have extra efficiency, the sensitivity you could set by your wiring arrangement. This gives more headroom and you could arrange your impedance to make your amp happy, and lose some distortion(admittedly minimal w/most modern amps) on that end.

                  How many tweeters are you going to need with your 6 woofers per side, at least 12 per side. Then the question is 6 drivers really going to be enough drivers to make a line array, more is better. I think you would need another 2 maybe 4 drivers per side. More tweeters, more money ... go with a nice 3 way.

                    Good question on 6 vs 1. Been wondering about the difference between an Uluwatu or high quality TM with a 12" sub.

                    Curt's Uluwatu with 6 woofers goes down to 20hz based on the charts with enough surface area to equal a fifteen inch woofer per side. If each woofer has 6mm xmax would that be equivalent to a 15" woofer with 6mm of xmax? Or does it work a little differently than that?

                      I'm not sure, but I think Ani is planning on this being a 3-way. The woofers in the multiple 830874 speaker would likely cross to a single the mid at 250hz. The mid will cover roughly 250hz to 2.5k, The speaker would be roughly 81dB at 2.83 volts. Obviously nothing has been set in stone yet..

                      What does SOTA stand for?

                          Also, the plan is a 3 way, with TMWWWW, but a short array of MMMTMMMW is also a possibility, the W being a huge 15" Prod driver capable of high SPL and sensitity. A nice 3 way on the other hand would be a TMW or TMSub with a state of the art T, M and woofer/ sub combo. either way, the M will be covering the midrange, say from 2500 to about 300 hz

                          So the question is more suited to that frequency range, from 300 to 2/2.5k what goes, leaving aside size.

                            Why not go with a larger woofer? Like one of the B&C 8".
