Again a small loud one-driver box isn't the same as having a wall of drivers behind you pushing all that air. Hell I even hate playing with just one of my 212 cabs nowadays.

If you take the same drivers out of those 212's, and put them in cabs with identical internal dimension/porting, taking into account proper bracing, but made out of light weight ply, they would sound the same. If the material of construction is greatly changing the sound, its a flaw in the design as those panels should be moving as little as possible.

I owned one for awhile and loved it. Very sweet amp with lots of power. Cant say I used the overdrive much but it was fun to mess with. I ran mine with either a PH412 or a pair of PH115 cabs. I eventually sold her off as my walkabout head was almost as loud and sounded just as good at half the weight. The BB750 is still one my favorites though.

Why would anyone do that when you already have the real deal? I guess if you have that kinda free time, you're free to and report back?
It's a whole 74 lbs. Hardly an amount to b!tch about. Still doesn't negate the "loud sound from small box" issue either which again doesn't sound good to me.

I'm not saying anyone should try this to alleviate weight. What I'm saying is there is no association between the weight of the cab and its sound, as long as there is no flaw in the implementation.

There is no "All other things equal, this cab weighs more, so it sounds better." The sound waves dont care what the panels of the cab are made of, only the way they behave when the waves hit them.

No but it does come down to construction and materials used- for example, at least on the Powerhouse line these cabs are pretty freaking deep. I think they're like 23" or something. My Berg NV610 was maybe 14, 15"? So you add an extra 1/3 of cab and sure it's gonna add some heft.
And I'm sure Mesa (who even if you don't like their amps, have a pretty rock solid rep for cabs in the guitar and bass fields) tried lots of stuff to get the weight down and went with birch instead.
I get your angle, but I guess if that only came down to design you'd see more quality guitar and bass cabs made of lightweight ply, and drums especially. Wood makes a huge difference in drums while the designs have relatively stayed the same for a long time now, so. Just my take anyway.

Well, I wouldn't hate to play in front of even the smallest of cabs or headphone for that matter, but I do enjoy playing in front of an 810.

As for the weight thing, I was simply saying that most of the cabs I've preferred seem to be of the heavier sort (think Mesa Diesel, etc.)

The reason you dont see more construction out of light weight plys with extra internal bracing is price point. The wood costs extra, the labor cost extra. Either end price goes up, or margins go down.

The SVT-410HLF are known for being very beefy (bottom heavy), and are quite a different animal from most 410s, which may or may not be a good thing. Not sure if the PN410HLF are the same.

Friday night I really struggled with my 3 Pro from a volume perspective. I took me a while to EQ for the room we were in. Dropping the gain & bass back from 1:00 to 11:00 and boosing the mid really made a difference...but the master volume was close to 3:00 and and I was hardly loud enough ... I need to be a little bit louder.

[pshep68]

Some friends are telling me that moving up from the Ampeg 3 pro, which is 440W, to the Mesa Boogie BB 750 which is 550W @ 4 ohms will hardly be loud enough for me especially if I am currently using the 3 pro close to the max. My current cab is the Eden 410 XLT(4ohm) ... what are your thoughts?

Secondly, if I do get the BB 750 and find it isn't loud enough with the 410, I could add a Eden 210 XLT ... since the BB750 can drop to 2 ohms....What are your thoughts?

Having owned a BB750 and have played a few 3 Pros, IMO the BB750 is significantly louder... Also, regarding the 210 XLT - if you can get an 8 ohm, that would be an ideal pairing with your 410, and would also make quite a difference in added volume...

If I get a 210 XLT(8) to go with my 410XLT(4) wouldn't that be a no, no as far as the impedience goes. Shouldn't it be 2 -8 ohm cab or 2 -4 ohm cabs?

[RickenBoogie]

The amp is safe to 2 ohms, (BB750), and an 4 ohm 410 paired with an 8 ohm 210 will show an impedance of 2.6 ohms, safe for the amp. More importantly, all 6 spkrs then receive equal power from the amp. If you used a 4 ohm 210 instead, those drivers would get DOUBLE the power per driver, and the 210 would not live long.

[Alex1984]

Yes. 8 ohm 210 and 4 ohm 410 allows even distribution of power without straining your head too much. And you get the versatility of bringing a 210, a 410 or a 610 to gigs.
