Double Bass Help with rig volume

Another thing to check is gain-staging. Regardless of sound quality, can you get more volume going direct into the Traynor and skipping the RedEye? If not then I agree to search for a more efficient cabinet - don’t get stuck on speaker size or configuration, just look for efficiency.
My experience with the RedEye is that it boosts the signal and helps control the low end, so I don't think it's a gain staging issue.

Well, IME I've actually never owned a 4 ohm speaker other than the Audiokinesis TC-112 and that is a very special cabinet. It has a amazingly musical sound with DB and
the crossover point between the Eminence 12 (Custom designed for Duke Lejune) and the special horn is set low so that as you move between different frequencies
you don't notice the horn. I've played DB on concert stages with that cabinet and a Walter Woods Electroacoustic amp or a Grace Designs Felix and a Jule Monique M700 and
it always sounded amazing and kept up. It's a combination of design goals with the TC-112 that make it an outstanding DB cabinet, but the 4 Ohm Eminence driver is part
of that design. Just my take. I will say that that doesn't necessary translate to other cabinets other than Euphonic Audio who are now out of business.

Jesus, how loud are you playing? I used the Woods LoPower (125 watts) for outdoor gigs with a quartet for years.

The Woods amps are rated for 8 ohms and for whatever reason just seem more powerful than a lot of other options. I finally replaced my 400 watt Woods with a new amp that is rated at 1200 watts. The new amp feels the same as the Woods does even tho it's rated at more than twice the power... Anyways I bet the speaker cab is the bottle neck in the OP's rig. I play acoustic often but I feel like a lot of bass players show up with rigs that are so small they might as well be acoustic. Showing up with a 10" speaker is kind of silly in my opinion if you are playing without the support of a PA. You might be loud enough on stage but it won't actually help you much out front and the group you are playing with will feel free to hit hard because you brought an amp.

It's kind of ironic that the worst gigs (loud restaurant etc) that pay the worst take the nicest equipment to sound good in. It's easy once you are playing nice clubs; you can show up with just your bass an expect they will know how to mic you.

Some of the Raezers Edge cabinets appear to use pretty low efficiency drivers, and some are only rated for 150W, so not the loudest 110s out there. It looks like they all use stock Eminence drivers, though, so that makes comparing specs easy. @sidonbass which one specifically are you using? If you just need a little more volume, adding an HPF and adjusting EQ might get you there.
Thanks
It’s a 8 ohm cabinet rated at 350 watts.

Rather than giving you an answer, I'll try and teach you how to make an informed decision. Ideally you do a little math and play through different cabs to choose one you like that meets your volume needs.

I haven't played the current Raezer's Edge offerings. I have demoed the older 112 cabs. I thought they sounded good, but had fairly low max volume capabilities. IMHO, plenty loud for most jazz trios though.

A 110 will generally not be as loud as a 112. But there are some super cabs, that outperform their peers. The Audio Kinesis cabs are generally regarded as super cabs.

The Raezer's Edge website indicates two models of 10" drivers are used in their 110 cabs. The Eminence S2010 and Delta 10A.

The cabs with the S2010 have a 150W power rating. Eminence lists the sensitivity as 96.2dB 1W/1m. This is sort of a medium sensitivity rating. Combined with the limited power rating, these cabs may struggle in a loudish jazz trio, especially if you like heavy lows. I think they would be fine for most of us in this setting, but it's not meeting your needs.

The cab with the Delta 10A has a 350W power rating. Eminence lists the sensitivity as 98.8dB 1W/1m. That a relatively high sensitivity rating, so I would expect it to easily work in a jazz trio, unless you really need a lot of volume.

It is common for the mechanical power handling for bass cabs to be significantly lower than the driver's RMS power rating below 100hz. Since the posted power rating of the cabs matches the RMS power rating of their drivers, I would be surprised if either cab can actually handle its power rating below 100hz. FYI, the mechanical power limits depend on both the driver's Thiele Small parameters and the way the cab is tuned. So the same driver will have different mechanical limits in different cab designs.

AFAIK, mechanical power handling is almost always less than the driver's RMS power rating. Sometimes the mechanical power handling may be as low as 1/2 the RMS rating. So the actual power handling of the Raezer's Edge cabs with the S2010 may be as low as 75W.

In regards to whether a 112 will be enough. I have an older GK 700RB/112 combo. The amp is rated to provide 225W to the internal speaker. I have never run out of headroom with this rig playing in jazz combos. In a big band I had to limit my dynamic range to avoid overloading the amp/cab combo. So IMHO the answer is a definite maybe :rolleyes:.

How much volume you need depends on how loud the band is, your approach to playing, and your expectations. If you can work with a 15W practice amp and feel satisfied, great. But that has nothing to do with my needs/requirements. I also don't really care that Jaco only needed four strings.

In the long run, I suggest trying to figure out what your SPL number is. Then you can do the math to figure out what gear meets your needs. The idea is to make a more informed decision rather than basing your purchase on opinions that vary so broadly.

My last touring rig had a stereo 250W power amp. I usually ran a single Eden D210XLT which has a pretty high sensitivity rating of 103dB 1W/1m. The calculated SPL with 250W is about 127dB. For the record, I feel I can usually get the job done with a 118dB rig, but in many situations I feel it lacks sufficient headroom. I feel 124dB is generally enough for most situations. There were times when 127dB was not really enough, but I am not really willing to turn up any louder...so the D210XLT generally exceeded my expectations.

To figure out the calculated SPL you need the 1W/1m sensitivity rating of the cab and the amount of usable power. The usable power is the lower figure between how much the amp can make and how much the speaker can handle. So for example the Eden D210XLT was rated for 350W but my amp only made about 250W at 8 ohms.

Formula
Calculated SPL = [Log(power) x 10] + Sensitivity Rating.

Eden D210XLT with 250W
Power Rating: 350W
Usable Power: 250W (limited by amp)
Sensitivity Rating: 103dB 1W/m
[Log(250) x 10] + 103 = ~127dB

You can also consider the advantages of adding a matching cab VS buying a different design to replace your cab. When you add a matching cab, the impedance is cut in half, the power handling doubles, and the sensitivity goes up by ~3dB.

So a pair of Eden D210XLT will have the following specs:
Combined Impedance 8/2 = 4 ohms.
Combined Power Rating 2 x 350 = 700W.
Combined Sensitivity Rating = 103 + 3 = 106dB 1W/1m

My amp made about 450W into 4 ohms
Calculated SPL
[Log(450) x 10] + 106 = ~132.5dB

This is 5.5dB louder than running a single D210XLT with 250W.

Essentially if you add a matching cab and the power stays the same, you get ~+3dB. This is the same calculated gain as doubling the power.

If the power doubles when you add the matching cab, you get ~+6dB.

In my example with two D210XLTs, the amp made more power, but it did not double the power. So essentially I got ~+3dB from the increased sensitivity and ~+2.5dB from increased power.

If your Raezer's Edge cab has the S2010 and we assume the 150W power rating is correct.

Calculated SPL [Log(150) x 10] + 96.2dB = ~118.4dB.

If the mechanical power rating is half the RMS rating, the calculated SPL is 3dB lower. (~115.4dB)

Adding a second cab and doubling the power gives +6dB, either 124.4dB or 121.4dB.

Let's compare this estimate to a couple of current 112 cabs

Genzler Bass Array 12-3
Impedance: 8 ohms
Power Rating: 350W
Sensitivity: 98dB

Calculated SPL at 335W. (I assume the Genzler can actually handle the amp's full power unless you really hype the lows).
[Log(335) x 10] + 98 = 123.3dB

So adding a matching Raezers Edge 110 should get you in the ballpark of a Genzler Bass Array 12-3.

Aguilar SL112
Impedance 8 ohms
Power Rating 250W
Sensitivity 99.9dB 1W/1m

Calculated SPL at 250W
[Log(250) x 10] + 99.99 = ~124dB
Lower power rating than the Genzler, but slightly higher calculated output due to the higher sensitivity rating.

Don't assume these calculations are 100% accurate. They are intended as educated guesses. If the calculated output is significantly more than you need, they are probably pretty safe. If the calculated output is borderline adequate for you needs, assume real world output is a bit lower.

Assume you need at least +3dB to hear a meaningful difference. So both of these 112 options should be capable of playing significantly louder than one Raezor's Edge cab loaded with an S2010. But they may not be significantly louder than a pair of cabs loaded with S2010.

Yes I know it's long :yawn::bag:...no pain no gain :p.

Good Luck!

Check out the recommended speaker designs document from Eminence. The very first design looks very similar to the Raezer's Edge cabs, and the mechanical power handling is only about 1/3rd the rated thermal handling. Also, the F3 point is very high, so users might be tempted to boost the bass EQ, which will push the woofer even harder. Looking at this design, I think we can see why Sid is hitting the cab's limits.

Edit: I just realized that there is a typo in that document. At the top of the attached image it says F3 is 63hz, then down below it says 87hz. IDK which is correct.

Eminence rates that speaker for 96.2dB "sensitivity". From their website:

"Eminence sensitivities are expressed as the average output across the usable frequency when applying 1W/1M into the nominal impedance. ie: 2.83V/8 ohms, 4V/16 ohms."

In my avatar you can see my rig of a Walter Woods MI-200-8 driving a Bergantino HT112, rated for 97dB at 1W/1M. The only limit to my stage volume is the point where feedback comes into play.

I suspect the connection of your preamp to your amp is the problem, since your amp is slightly more powerful than mine.

I can understand the confusion based on the response plot. I am not an expert but I think the correct answer is F3 = 63hz.

In the displacement chart, the excursion quickly rises beyond Xmax (3.5mm) as the frequency drops below 64hz (Fb). Fb = port tuning frequency.

Good point. I was going off the numbers to the side but didn't think to read the graphs. This one shows it better. Looks like the F3 is eighty-something Hertz. I think the 63 number probably comes from the "usable frequency range" spec (63hz - 3.7khz).

something that has always stood out to me is none of those companies used "of the shelf" Eminence Speakers.
I know for a fact that the EA VL series I owned used 8, 10 and 12" speakers that were customized with kevlar coated
drivers and different surrounds. The TC-112 is a 4 ohm custom Eminence 12 that's specifically built for Dukes Thunderchild
boxes. Mike Arnopol's MAS 1/8 and 2/8 used a custom 8" driver. (he later went with Ciare) I've never seen response curves
for the TC-112 or the MAS 1/8. Based on Jim Bergantino's reputation my educated guess is that he does the same l Just my take

Well, as with all things there are exceptions, IME a MAS 1/8 cabinet with 500 watts can sound quite loud on stage but it also blends with the ensemble.
so out front it may not cut through the other instruments in the same way a larger cabinet would, but it can be heard.

True, things have gotten better though, smaller P.A.s can actually handle a Double Bass these days. Imagine trying to run a DB through a Shure Vocalmaster or set of Peavy Columns. :laugh:

None of the TC cab iterations ever used off the shelf drivers? I thought he had used one or two at some point, but I'm probably just confused. I believe the Birdhaus cabs used off the shelf Faital drivers (6FE100 and 8PR200 IIRC).

I recently bought Eich 112XS 8ohm I can warmly recommend. It's quite lightweight, sounding very clear and covers a large area. Seems to me like an ideal cab both for upright and slab. Paired with GR bass One 350, I never put the volume over 2/10 and whole bigband can hear me.
I also tested its smaller brother 110XS, very similar sound, but the area covered and the authority of lows is, after all, significantly smaller.
 
Probably great - but you won't know until you try it. I'd roll with another razor's edge 10" because I prefer how they sound compared to the Acoustic Image speakers, but you might love the way the Acoustic Image stuff sounds. I have a feeling 2 of the razor's edge speakers would give you more volume.

If you were ok with carrying two cabs, I'd go for a second 110 to match what you have. Personally I am a fan of RevSound cabs - I use a 115 (25 lbs) and its plenty loud. I have a 112 to pair with it on the way - just because 2 cabs are better than 1!!!!
