    Very Nice, Mike! Let's get it into your catalog.

    Beautiful work. This is like the mechanic finally getting a nice car to drive after fixing everyone else's.

    Thinking I want to start my MAS bass guitar adventure with one of these, an MAS66. I've read that the MAS110S is an excellent choice to pair with the MAS66 (maybe the best?). don't doubt that. But I think I just don't care to go that way, at this time anyway.

    I'm thinking, though, that I also want to try a MAS112, not just to pair with the 66, but to get a feel for another MAS box, & to try pairing it with the 66. Which MAS112 do you think (or know?) would work better with the MAS66 when paired? The Faital? The 18Sound?

    Also what's the ohms of the 66 cab? And curious, may I please ask which driver is used in this cab? Should the 66 be paired with a 4 or 8-ohm 112?

    Are the various MAS cab dimensions/weights (at least ballpark) listed somewhere? Can you please direct me to that place?

    What are the RMS ratings for the 66, the 12MB1000 112, & the 12HP1060 (& it's the 60, not 30?) 112? And how much RMS does each cab really like to get humming?

    Sorry about so many questions. I'm just kinda excited. Thanks very much.

    I would say that the Faital loaded MAS-112 would be a good pairing with the MAS-66. Use the following for comparison:
    MAS46 600 cc's 600 watts
    MAS 66 900 cc's 900 watts
    MAS112 w/18Sound 900 cc's 800 watts
    MAS112 w/Faital 900 cc's 1000 watts
    MAS112 LPT 660 cc's 450 watts
    MAS 210 Flex 1200 cc's 900 watts
    It takes about 40% power to really start getting the Vortexitude going.

    Now is the time to grab an MAS-66.  Check this out: [You must be registered and logged in to see this link.]

    I'll let Mike comment further.

    Hi

    You know, it's easiest to just give me a call (with so many questions!).

    My cell 224 628 6162

    First of all--the woofer in the MAS112 18Sound is the 12NLW9300. It has a lower fs (by 10 hz) and a much longer excursion than the 12MB1000. It's also lighter because it's neo. (and a lot more costly)

    The Faital is indeed the 1060.

    The woofers for all of the 6's (really 6.5's) are a very unique custom driver that the head engineer at Eminence helped design. Crazy low FS and very long excursion.

    To pair with the 66 I'd actually recommend the 112 with the 18Sound .The 66 and the Faital loaded 112 are both balanced, but warmer in the low end. Controlled and not at all boomy but fuller. The 18Sound is a bit more muscular and less pronounced in the mid-to-upper bass. It's also more mid-forward. It's hugely powerful in the mid-to-low bass. I think that it would be a good compliment to the 66. And there would be a lot of versatility in that separately they have different voicings that would function well in various contexts but together they would be great. Of course---with a little eq either could sound close to the other.

    I'd go with an 8 ohm 66 (the 66 is either 4 or 8 ohms) and an 8 ohm 112 with the 18sound.

    The 112's and 66's are both 900 watt speakers. That's a thermal rating (as all published peak wattage claims are) which means that if you surpass that for a length of time you can fry the voice coil. They can actually go past 1000 watts as short bursts no sweat. But I'd say that an honest 600 watts (into 8 ohms) would be enough for either a single 112 or 66. 500 would do it, but you'd cap the amp before the speaker. If you paired an 8 ohm 66 and an 8 ohm 112 that 800 into 4   would do it---but more would be better. For the two together I'd like to see 1000 into 4. I use the ICE 1200 watt module and it gives enough headroom for the pair. (look for the new MAS/Sonic Farm amp---1200 watts )The extra power gives more headroom for a more effortless sound.

    Dimensions
    MAS66 26 wide x 22 1/2 high by 14 deep---around 62#
    MAS112 32 high x 15 1/2 wide by 14  1/2 deep  around 52#

    One more thing----there is a HUGE difference between the 1st generation 46's and subsequent ones. A bit too scooped in the mids, IMO. The Faital 3's make a big difference. Also, a lot of improvements in cabinet tuning. A lot. The first gen cabs do all of the Big E stuff but most of the work since then has been in getting the frequency response and voicing right.

    As much as I like (and am proud of ) the first gen cabs, there is really no comparison. Got to get those mids right!

    MAS112 32 high x 15 1/2 wide by 14  1/2 deep  around 52#

    So, you'd lay the MAS-112 on its side (long side horizontal) with the MAS-66 on top?
    No major impact on projection / dispersion?

    ^^^ That would/will be how I'd attempt it. Don't see another way.

    The MAS-66 and MAS-112 are both full-range loudspeakers. Therfore, there are several different ways to place them. Placement with the 112 on the bottom would couple the 112 to the floor and generate a but more low end. The dispersion in that position will be at least 140 degrees. In a boomy room or just for a change of tone they could be placed side by with the front edges as close to touching as possible. This will produce a bit leaner muscular tone. The dispersion will be about 120 degrees. One could experiment further.   Some other positions will produce comb filtering which may or may not be desirable.

    MAS112s. 18Sound & Faital. Vd 900cc each. Curious. Is this Vd an exact (or pretty darned close) number? Thanks.

    Ok--I got a bit conservative here. Eminence, Faital, and 18sound use different formulas to determine VD, so through my experience I've interpolated. Faital is VERY optimistic. According to them, the 12HP1060 has a vd of 583 cc's. When you combine the back wave you get 1,167 cc's. To compare apples to apples, I estimated that down to 900 cc's, which when comparing to Eminence is more accurate. The 18sound is very conservative in their formula. According to them, the 12NL9300 is 424 cc's. Multiply that by two and you get 848 cc's. Using Eminece figures as my yardstick, the 18Sound would be more like 900 cc's. Eminence's 3012lf is listed as a vd of 496. So times two that's 992 cc's.
    So---the Eminence should be the loudest of the three, right? Fartout point on the three is about the same place. But---the Faital and 18Sound sound pretty darn clean up to fartout. The Eminence starts getting "fuzzy" before the other two. So----I try to base my vd claims tempered by personal experience. Also. since the Faital and 18Sound use 4" voice colis (the Eminence is 3") they do much better with thermal compression.

    BTW---I'm working with Eminence to design a brand new 12 that combines the punch and midrange excellence of the 3012HO with the low end extension and excursion of the 3012LF. Efficiency should only be a touch less than the 3012HO. So---hopefully---the LPT could have much better extension and go louder. We shall see.
