The Acoustic Club

Question for cab-geeks:::

What, with the existing tube/port design on my B-450, would changing to a shelf port on the B-450 MKII do?

According to the write-up for the B115 MKII "The shelf port provides additional low frequency projection".

There is some sales play going on here also in that they didnt port the first generation B115 and got a bit of flack from us users. IMHO Acoustic decided that shelf ports would sell better than circular/tube ports.
 
I think I saw one on the newer B-100s at my local GC, but I didn't pay attention.

Would like to know the price points of the new amps/cabs, and what is the frequency range of the ported cabs, especially the 260.

That brings up a price point then- plastic tubes are a lot easier to install (1- drill hole 2- shove in port 3- glue in place) than building a shelf port I think.

I know the tube ports on my B-450 get a serious workout, as they are pumping a lot of air (or is it sound?) out the back all the time.

If things are tuned correctly in either case, I bet the design won't matter much at all - right?
 
I have owned a 370 since new in 1974. Love it; just too loud for what I have been doing lately.
My wife bought me a GC Acoustic B200 combo in 2009; I still love it. I have joined a band which has tons of JBL PA and I plan to use the DI as well as the amp itself..I digress..

So a mention was made at a band meeting about having to haul our stuff up a couple of flights of stairs at an upcoming gig. A B200 H with seperate cab weighs less [seperately] than my B200 Combo. Last Saturday, my wife drives us to the Fayetteville GC and suggested I order a seperate head and cab for weight reduction..I LOVE MY WIFE..... My fave G C sales guy, Steve searched system-wide and found me a new-in-the-box B200 head and 1x15 cab for $100 less than my B200 combo cost 3 years ago. All I have to do is wait until it is shipped to the store and I will have yet another GC Acoustic amp.

I believe that the B200 Head can also run 2 cabs without an ohmage issue; unlike the B200 combo. If needed, I can run the B200 H and 1x15 cab stacked on my Marshall 1550 cab, or oddly paired with my trusty old/ heavy Kustom 200 cab
[ 2x15]. Ultimately, I want to run my Rick 4001 in stereo; one P/U per Acoustic amp; don't know which will be bridge or neck amp yet. I'll keep y'all posted.

I am sure the the newer Acoustic heads will obsolete the lower wattage heads, but I don't need any more wattage or I would use my 370 head, which weighs 45 pounds; also a weight issue, as well as the Sunn Cab it ususally goes through.

Zon6c...Let me say I think your going in the wrong direction if your concern is weight. I own the B115 and at 63 lbs it is only 9 lbs lighter than your B200 combo (72 lbs). Add that to the fact that the B115 is larger and more combersome. The B200H head is not a bad choice esp at today's price point. May I humbly suggest you find a very efficient ,fairly lightweight 2X10 to go with the B200H. Acoustic makes a 2X10 Neo cab that fits the bill but not your price point. There are many others. My B115 stays home most of the time and I use a 450W head and a 2X10 Neo cab for small/medium gigs. For larger gigs I have a compact Neo 1X15 under the 2X10. Each cab weighs no more than 44 lbs and is compact.
 
5port: Thanks...and my new rig is ordered and in route to my local GC. Hey..I'll take a few pounds less..LOL.. I mean; it's a done deal and all....we'll see. Agreed: 2-10's would be lighter...

Last night at rehearsal, I plugged into our PA from the DI-Out from my B200 combo. Signal about half way up. Sounded great; clean signal. It sounded..like my amp, only "twice."

Down side is that I am lucky to have slender enough fingers to depress the release switch from the low-z mic cable. GC Acoustic gave us a great amp with a DI line -out, but we need about 1/4-1/2 more wiggle-room. The DI is very close to the top of the amps housing.

Hopefully my new B200-H will be easier; or at least identical identical, then I will have to deal with it. Long story short: The band is very impresseed with my sound and delighted at the flexibility of a DI-out as opposed to micing-out and subsequent issues.

Fingers crossed that my Rick 4001 will be ready SOON from repairs and I will run stereo with (2) Acoustic amps. Otherwise my main-go-tp bass is a 2009 Squier Jazz-5 Active. It is a tone monster. The mid boost switch thickens things up when our keyboardist is not playing.

Having (2) "identical amps" will reduce my desire to also lug my Marshall 1550 cab.
 
Looks like the B-600H may still be around - but the MKII stuff might replace it all. Confusing too to me, since GC is dumping the non MKII stuff for super cheap.


I'll be sorry to see the 2-Ohm B-600H/B-450 die though.

I will be picking up a barely used B-600H with B410 cab hopefully this weekend. Getting it at a really good price. Now I will have a vintage Acoustic 140 head and a newer Acoustic head!!! I will find out how much work the 140 will need if at all as soon as I plug it into the 410!! Keeping my fingers crossed on the deal and the 140 working, lol.

Just asked Acoustic Amplification if they were phasing out their bass gear over on their Facebook page. They said emphatically that they were not phasing out the low end in any way.

That is good to know!!! I was at GC today checking out some gear. I noticed they had some of the new mk2 combos in. No Heads or Cabs,either old model or new models.
 
The Acoustic herd is continuing to grow. When do you become a collector and stop being just a user?

118, 126, 165, 360, 361PP, 370, 400, 408, 411 (2 of 'em), and a PA120/6. They follow me home and I have to keep 'em.

Yes the 126, I had two of them I would stack sideways.
My idea of micro amps at the time :) Good times :hyper:

None of these are mine, just for viewing :)
