Carvin B1500 with Acme Low B Cabinets

#41
I didn't have rehearsal tonite, so I haven't yet heard this combination at gig levels, but at home volume it sounds great:)

very even and balanced sound with my Roscoe-compared to the accugroove tri112s I traded for them, the differences that immediately jump out are more detailed highs and much less-pronounced midrange--the midrange voicing of the accugrooves isixh more apparent after hearing these acme cabs...which is good with me because I have plently of midrange available from my instrument and amp when I want it

Holy Crap!

Roscoe's into Acme's -- you won't be lacking for low end output!

I run a b-1500 into a lowb4/4ohm & a lowb2/8ohm. Its hard to discribe the sound ......
incredibly deep,warm,articulate,earthshaking,kinda like gooey dark chocolate syrup?? even at high volume levels it
completely blows away anything else I've ever played through!

I can't comment on the B1500 but I use the BX1200 with both power amps bridged into an Acme B4/8ohms. I am pretty sure that is putting out 800watts when bridged and I can tell you it's the absolute best bass sound I have gotten over the years. My guitar player who has 30 years of experience and much of it as a pro touring musician said that is exactly how a bass amp is supposed to sound. I can't imagine being happier with my bass rig and I think you would be plenty happy with the results achieved by combining the 1500 and Acme cabinets.. This is all subjective of course and just MHO ;)

I have a very recent recording of the band from out last gig. It was made with a ZOOM H2 about 18 feet out directly inline with the bass amp. I'll make a clip available for you to listen to and post a link shortly.

The clip is up on my iDisk and can be accessed Invalid Link Removed

The first two clips are from the live gig. Solo sections of Cheap Sunglasses and Sunshine of Your Love. The 3rd snippet is from our rehearsal space and is the first two verses of What Is Hip?. The signal chain for me is : Carvin LB70, BossOC3->EHX Qtron->EHX Big Muff Pi->BX1200->Acme b4/8ohm. All the clips were captured with a Zoom H2 placed in the room we were playing.

Doing what you are is the correct way. Each of the six 10s is getting the same power as any other.

I merely posted a rebuttal of the mind set that says overpowering speakers is how you get headroom. Using my 350W each into a pair of Acmes I have headroom in spades. I cannot imagine why anyone would want to drive a speaker system past its capabilities in the name of so called headroom.

Having more power available and using all that power are two totally different things.
Sounds like you do not push your cabs to anything close to their 350W rating -- that's why you still have available headroom.
[We're talking about musical signals here, not sine waves.]
If a person knows their equipment and sets the gain structure up appropriately, even with amps having 2x the rated power, the cabs will not be getting significantly more power than you give yours and even the short bursts of energy used will be so far below the amp's limits that it will be literally coasting along.
There will be no stress on the amp and more importantly, no stress on the drivers in the cabs.

There is no doubt that someone can abuse a setup like this and damage drivers, but I always attempt to give fair warning to those that I advise.

'Stupid is as stupid does' as Forrest Gump's mother used to say.

Using the generic "you": ;)

All I'm saying is that you don't NEED a honking great power amp to run Acme cabinets which seems to be the general belief on this site. If you decide to use one that is your choice but you have to be continuously aware of the limitations of your speakers. If you have arrived at a venue with insufficient speakers you are going to have trouble. The obvious move when you are not cutting through the mix is to turn up. Very soon your speakers die even if your amp is just cruising along. I'm sure you personally know how to use your equipment but, as the posts on this site prove, many others do not.

The secret is, IMO. balance. Learn what your equipment is capable of. Know when to turn down and when to add more speakers. Taking anything past its capabilities is not something that is advisable. If ever I think that my pair of B2s will not be adequate I simply take my second pair and a more powerful amplifier. I still, however, keep the available power to 350W per B2.

Here it is... 1250 watts of honesty!
Still experimenting with EQ and speaker placement. I might try stacking them sideways with the mid drivers aligned.
