people will still hear the harmonics, and our brains tend to fill in the blanks.
Absolutely correct. Organ builders from long ago knew this and guitar players using ‘power chords’ know this.
This effect is most noticeable with Perfect Fifths or Fourths. For instance, the frequency of an Open G-string (on a guitar) is appx. 196Hz. and the Open D-String is appx. 147Hz.. Play these together through a Marshall with some good crunch and you will hear the Differential Tone of appx. 49Hz - or a Low G. This is the effect used on the opening chord to Smoke on the Water.
But… if you want to produce the Fundamental and NOT a Differential Tone at a substantial volume, you will appreciate a well designed speaker system that can efficiently reproduce the pitches from the Taurus 3.
The Acme bass cabs have a freq response of 41hz to 22Khz, +/- 3 db, -6db at 31hzwith sensitivities fron 90 to 96\db, depending on which cab is used. Coupled with an amp putting out around 800 watts, you can get way low!
The info on their sight (for their smallest cabinet - Acme Low B-1 Series II) suggests that the lowest frequencies drop by 6db @ 31Hz (Low B-string). And if I did my calculations correctly at FULL rated power (175 Watts) a Low B comes in at appx. 112dB at one metre. That’s pretty good! Their BIG cab increases quite a bit over the small one. If you can get a 700W+ amp and the Acme Low B-4 Series II cab, at one metre the SPL of a Low B would be at appx. 124dB.
The question about this cabinet is whether it can project these frequencies well. It’s well priced. It’s got midrange and horn components. Real Hi-Fi for bass. Drop another $2,000 and one could have a nice rig for the Taurus 3.
I believe that in order to effectively project sounds at those wave lengths, the cab would need to be on a stage in a large hall, or outdoors. I also believe that you would need to be at least 25 feet or so away from the front of the cab in order to get the full effect of the wavefront developed at those freqs.
I would love to see someone point me to a PA system or explain to me how to hook a crossover and subs to a PA and point me to a PA with speakers adequate enough to handle the specific frequencies that the Taurus is putting out.
I am beginning to think that the best thing to do is to let Moog make the reccomendation.

Where will you be using the T3?
I’ll most likely be using it in my studio. Here is my sub woofer:
Event 20/20 s250. The specs: 15" speaker, 28Hz - 120Hz, -3dB, 250W - SPL: 117dB @ 1 meter. It’s a powered sub and I have powered full range speakers for the rest. One could get a PA system that is similar. You just need to know what you’ll be using the T3 for.
I rarely listen to anything above 100dB or so. And, I only need to fill about 2,200 cubic feet. A far cry from filling a soccer stadium.
The Event 20/20s sound like the ticket! Decent specs, and I like that it has an adjustable crossover. What I don’t like is that the driver uses a foam surround. These tend to deteriorate over time. However, whenever it does decide to crumble, the surround can be replaced with a rubber surround pretty easily. Here’s the link to the user manual:
I appreciate the links so far. I don’t have any plans on gigging with the it. I will be using it primarily for recording at this time, however, I want to have something that I can run it through where I can at least hear the sound that I purchased.
Being basically cheap, I started looking at the Behringer Truth B2092A studio subwoofer. Reviews I’ve read say its sound is well defined, and not muddy. Seems it is really unobtrusive, and reinforces the low-end without being boomy or strident. It uses XLR ins and outs, and has a phasing switch along with a room contour control and input trimmer. A couple of caveats are that the wattage spec is higher than what the power supply spec shows. Also, the amp apparently runs kind of hot as well, so it needs to be out in the open, away from radiators and such. At around $200, it might be worth looking into.
I started thinking that I might want to get one, but my Nady monitors put out enough bass for my uses, so I think I’ll save my money for the time being.
Only one issue… where can you buy one? It doesn’t look like anyone’s selling them.
Yes, it looks like these are ‘unavailable’. You might get a good deal on a used one. Check the usual places: ebay, craigslist.
I do seem to remember that the ‘s’ in s250 meant that it is the ‘short’ model. The regular 250 is taller. But I could be thinking of something else - as I usually tend to do.
I’ve had mine for about 4 years. I don’t see any problems with the woofer. I don’t always engage it when I am tracking or even during mixing, though. I use it more as a ‘check’ during final mixing or mastering. It sure makes the music ‘feel’ good!
There must be other comparable subs out there. But it is nice to have the options provided with this particular model.
I actually find that I get very good bass with my 6.5" monitors. I A/B’d them with a set of good headphones, and they are comparable. (I know, I know… no pant flappin’! But I have neighbors with very loud sound systems. Call it detente… )
Actually, I’m afraid that after dropping a ton of money on a subwoofer, I’d decide that it was just muddying up the mix and stop using it.
Update: I am a certified gear slut! I’m not even a discriminating slut at that! Behringer?!
Damn!
I kept reading about the Behringer TRUTH B2092A subwoofer, and the more I read, the more I had to try it! I found it on provantage.com for $191 shipped, and I couldn’t resist!
Ive heard so much bad stuff about everything Behringer, I would probably not buy Behringer toilet paper cause it would probably just get my hands dirty.
Actually, I have a few Behringer items, and they’ve managed to survive to this point. From what I’m reading, this subwoofer sounds pretty good for the money.
Ditto. I have a Behringer mixer, and its been very reliable. My buddy has a Behringer bass rig, and it is just an absolute turd. For my Taurus 3s, I had a Peavey Tour TNT-115 combo on order from Sweetwater, but I cancelled my order (no telling when they are ever going to ship) and instead ordered an SWR Headlite 400-watt head which I will run through my Sonic cab loaded with a JBL 15" speaker.
The bottom end specs on the Behringer sub look real good as does the price. Nothing I have goes usable (-10db = 121db) below 43Hz. In reality, will I feel much difference on stage playing rock covers if I find/build a speaker that goes to 31hz (or lower)? Opinions? Thanks.

Do a 360watts sub can help feel the bass in a room of 16X24X7 fill with 1 drum, 2 guitars, 1 organ and keyboards? I was thinking about building a Tuba HT from Bill Fitzmaurice…I already have a DBX crossover and a QSC amp so could be a good way to go. Maybe I should just wait for the T3 and see what to do from there…
+1 on the BFM Tuba designs. That was my next solution.
As for feeling the bass in a band situation, stage or rehearsal room, I use a pair of 700w QSC HPR151i (front loaded, front ported, 15 inch) subs with a pair of HPR122i (400W 12" + 100W 1.4" horn) passively filtered at 100hz and I can pump the entire band (3 vocals, 2 guitars, bass, keys, kick, overhead) through it and cover about 250 people with enough bass for 70s/80/s covers. QSC specs them at 131 db, FWIW. So, yeah, I think the 360 W Behringer crossed at 80 would help feel the bass in that room or on a pub stage as a monitor.
