Double Bass MAS 46

I’m looking at buying a used MAS 46 for medium sized rooms, possibly a second one someday for concerts and large rooms. I have most of the specs except the sensitivity. I’m wondering if I can push one 8 ohm (400 watt) cab with a Mesa Walkabout (300 watts at 4 ohms...). MESA doesn’t list what this amp produces at 8 ohms (I’m guessing around 175 watts). Without all the needed specs available, I’m wondering if anyone knows if my Walkabout will have enough juice to power a single 8 ohm MAS 46. Thanks for your time, it’s much appreciated.

Keith,
300 watts at 4 Ohms is roughly 200 Watts at 8 ohms so you'll loose about 33%. You’d be pushing that Walkabout pretty hard but it all depends on how loud the gig is.
 
FWIW, I use a MAS 45 with my AI Focus (450W at 8Ω) to drive a big band (17 pieces + 3 singers). I have used the cab alone in fairly large ballrooms without cranking the amp too far (never more than halfway and no fartage). I don’t think much about how big the room is because I’m not trying to fill the room; I’m filling out the band, which has the same wattage, no matter the size of the room. (Only the singers and three soloists are in the PA.) I have brought a second cab (EA Wizzy 12M) as insurance, but haven’t needed it.

a 4 ohm cab, yeah. 8 ohms---IMO---it would be pushing it.It would work, but you'd lose a lot of headroom. Thump and thud live in the headroom. BTW--the new 6" based cabs are about 3db more efficient. Maybe 4db. Those would work

Yes, there are, last I heard, Mike’s working with prototype 2x5’s and 2x6’s a local Chicago bassist loved them. I talked with Mike talked briefly about them, I think he said they are tower arrays.
Cool...Mikes got that MOJO workin’... I think there’s something to stacking multiple speakers vertically. The old Ampeg 810, arguably the punchiest, purest bass sound ever (at least with EB) was two vertical rows of four 10’s. I think the bottom speaker allows some coupling while the further up you go, the better you hear your sound, and can dial in accordingly. Whatever the end result, there’s no doubt that Mike Arnopol will figure out some new formula that will once again raise the sound bar for all of us simple folk to enjoy for years to come! :)

Well, of course you’re right, I owned a Euphonic Audio VL-208 and a VL-110 stacked together it was quite the array. There were TB members who used pairs of the VL-208’s for BG. It took a lot of juice to drive that stack. Mike’s cabs have the juice built in, are a quarter the size and weight and sound phenomenal, especially with DB. My MAS 4x5.5 will smoke that EA cabinet in tone, size, weight, and definition. Just my take though.
 
Just been A/Bing the MAS18 against mthe 46. The 46 has been for years my sound and my whole eq worked around it. The 46 is a great speaker-what mike said in the other thread seems to be perfectly true on comparing them- the 46 is slightly bumped in the lower mids and the 18 is bumped up higher. Both have highs for days (46 has 3 mids and a tweeter and the 18 one of each) but interestingly the difference for me came down to with the 46 I can use the Yama pickup bridged (which cuts bass and favors mids) and with the 18 either side (E or G) sounds fantastic by themselves but not bridged. I'm getting this super fine woodiness with the 18 that is more thick and smooth with the 46. Either is totally rich.

So.....what I’m wondering is, are there plans for a new MAS cab in the works with 6” speakers?
Since you asked
I think I'm cool with the CUP rules on this
These are prototypes and in development
People complain that "why should I buy one now since in 6 months it will be obsolete?""
Actually I had my line down and was pretty happy. MAS16, MAS18 &28 MAS110, MAS112 and Bodai 28, 110 and 112. I felt pretty solid. Of course there would be little improvements here and there, but the models were cool.
Then Eminence changed their policies because of new management. Instead of buying 50 drivers I had to buy 100. On the Kappalites minimums went from 12 to 25, but would go up to 50. I just don't have access to the cash to do this. I was pretty sure that I would have to close my door.
Then Ciare---the high end of pro sound drivers was going under and was bought by 18Sound. Then 18Sound was bought by B&C. B & C is HUGE. They wanted Ciare to be the absolute highest end drivers. The US distributor is a friend. He asked me for the specs on my drivers. He sent them to Ciare and they handily beat them on the 5's , 6's and 8's. Better all around. The engineering and construction is second to none. Meyer used to use mostly Ciare and had to stop because of Ciare's problems. These new drivers are WAY better than the ones Meyer was using. They cost more. Maybe around 30% more. But that only brings the cab price up by 15%. It's worth it. Oh--and they added my drivers to their standard catalog. (I told them that I preferred this}.So--I can buy them in any quantity. A HUGE weight off of my shoulders.
I feel that the past 5 years were preparatory in terms of solidifying my knowledge and that it all led to this moment. We have learned how to really use this wonderful technology. I have clear knowledge of the goalposts I'm shooting for. I don't worry about competing with other manufacturers---I'm now just competing with myself. A problem with the Ciare 5's and 6's is that they're really flat. My cabs roll off much less than others--a good and a bad thing. Good because I can get more bass weight and extension. Bad because by comparison the mids sound depressed. They have WAY more weight and power than my other speakers. But they cab sound dark because of it. With the Bodai's---no problem because the mids are a completely separate entity and can be easily manipulated. But--the MAS line is my bread and butter. What I needed was a 3db/octave crossover--which doesn't exist. I called up Steve R. and told him the problem . Off the top of his head he came up with a unique idea and said "try this". I did and it worked perfectly. The mids did a gentle upward slope from the point I wanted. I called Duke--he's by far the best crossover guy around. He said " I think I can model this on my software. Duke is a Southern gentleman and never cusses. He ran the modelling and said " Steve is a MF." It modelled like a perfect 3db/octave crossover. That parts the clouds for me. I can't manipulate the woofer from the bottom to 250hz. This is the most important part for me. Thr Ciare's have more weight , impact and extension than any speaker I've tried. Especially the 5's and 6's. They WASTE my other speakers. I can now manipulate the mids and highs to get anything I want.And they are more efficient. The drivers are about 2db more efficient and the new cabs are actually another 2db more efficient. And when you multiply the drivers yo wind up with cabs approaching 100db efficiency. The 18 is only about 95db efficient--but that's 2db better than the previous one. And all of the drivers are available in 8 and 4 ohms.
In the picture are prototypes I'm working on
On the left is a 4x6 Bodai tower on top of a MAS26 tower. I LOVE the towers---clarity, clarity, clarity. Some guys don't like that their amps "muffin top" on them. So I also will have the MAS46--empty cab on the right. A MUCH better version of the original 46. On either the Vd goes up to 750cc's. Much louder than the original 46. A nice thing about the Ciare's is that the Xlim--the point where you're past the Xmax where your drivers will "hit the wall" is much higher.Next to that is a MAS25 on the bottom topped by a Bodai 45 tower. The 45 is around 500cc's. While the original 45 wasn't very good for 5 string, this is better than any previous cab for 5 string. Radbass, Leland Crooks, And Big Red heard this against a Bodai 28 and a new Bodai 110 and all thought that it easily wasted them. For those who don't like towers is the new 45 next to it. It's missing the tweet. I'm not sure if I'll stick with the towers or the cross-firing ones. Each has its advantages.
Ok--next comes the "personal journey" part. Feel free to skip it
As many know, the past year has been incredibly challenging for me. Lots of health challenges that after being resolved led to a much healthier me. Two small strokes and devastating prostate stuff. (I know---too much information.) Well I've now gone from 6 bathroom trips to one. But the biggest breakthrough was last week. My sisters and I have a really hard time falling asleep. My 3 sisters take Ambien every day. Instead, for the past 40 years I've smoked or vaped to get to sleep. Never during the day, NEVER when I'm playing. Well--also---I'm always in a hurry so if I can't find my dust mask--I do without. Which was most of the time. 11 days ago I was going to bed and took one vape hit (I have a prescription) .I immediately started coughing uncontrollably. And my lungs seized in an acute asthma attack. I don't have asthma normally, but do have an inhaler on hand. I couldn't breathe at all. Three puffs and 3 Benadryls got me past the critical point. I called my doctor in the morning--A bass player and friend and head of medicine at a major Chicago hospital. He put me on serious steroids. No more vaping---ever. I decided no edibles or tinctures either.
I was petrified---I hadn't gone to sleep without in 40 years. I'd bring Ambien on the road if needed.
My son had me watch a Joe Rogan podcast with a sleep expert from Stanford. He said that if one uses cannabis, alchohol, or sleep aids that you bypass REM sleep and go directly to deep sleep. He said that you don't dream, or dream very subtlety but likely not at all. He said that you are constantly sleep deprived. I realized that I'd been sleep deprived for 40 years. In the past 5 years I've felt like i was "swimming through Jello" as far as life. I was always super fatigued and clinically depressed. I had to take a nap every afternoon. My concentration was crap. Everything was crap.
Well--it's been 11 days and I feel like I've awoken from a bad dream. Which was my life. My dreams are INSANELY powerul. Like in Technicolor. I can remember every detail from a dream a week ago. I wake up happy and hopeful. Sounds corny--but true. My depression has gone away. My sinuses are open. My allergies are gone. I've never felt this good. I'm now super excited about my speakers and am determined to become an expert at filter design and am confident that I can improve them to a level that I couldn't imagine. I no longer have to nap. I played a gig a few days ago. I can't remember playing better. It's like I had ten minutes between each note to make decisions.
I know this sounds like I'm totally nuts but I feel like e very different person. I'm just sharing this (way too much information) because I'm more than a little embarrassed as to how I've behaved on this forum in the past. I'm not making excuses---I've been a real weenie a lot of the time. I'm super stoked about going forward. It's pretty embarrassing sharing this, but I feel that all of those who have my cabs are good friends. I now feel like I can be a good friend back.

Zombie thread resurrection. Night of the living cab…

I recently picked up what might be Mike’s last ever MAS 46. I know several DB cats really loved this cab. I wanted something that had more low-end weight than my Doubleshot (which I love). The MAS definitely delivers the low end, but I’m stunned that with 4 3” tweets plus the 4 6” drivers, I’m not getting more clarity. I’m curious to hear from folks about their experiences EQing with this cab, particularly those who have driven it with Acoustic Image heads.
 
Well,
I own the "Baby Brother" of your cab a powered 500 watt MAS 4x5.5 which sits in the sweet spot between the first 4x5's and yours. I've used that cab with a Walter Woods Electroacoustic Ultra (600 watts RMS),
and a Monique M700 (with a Grace Felix Pre) the clarity on mine is really good. I've only played through a 4x6 once to demo it. Acoustic Image Heads aren't my cup of tea, but their highly respected amps.
