At first I was using a single PB-210H with an Ampeg B2R head and it sounded good. But after I got my second cab I needed an amp that could drive 2 x 4 ohm cabs. I decided to go with a QSC PLX1602 power amp with an Alembic F1-X pre and it has opened up a whole new world of clarity and tone for these cabs. The low-end has a lot more booty now.

So word of warning: make sure you have a really good preamp/amp to go with this cab. I have not tried it with the PB250 head because it seems underpowered.

The cabinet is very portable thanks to lightweight magnets and plywood. It comes with a built-in, removable, telescoping dolly handle which makes you look like a tourist moving through an airport as you load in your gear. I like it though because it's easy on the back.

To give you a better indication of how portable this thing is, it's the only 2x10 cab that provides 400w of power and can fit in the passenger seat of my Mazda Miata along with a bass guitar. (My original reason for looking at it)

I have had the tweeters go on each of my PortaBass cabs but one was due to a power surge. The other, however, seems to be simply because I had the tweeter turned up too high. It started sounding like paper. I was not able to get Ampeg to cover repair costs under any circumstances so far but in their defense, this problem does not seem to be reproduceable in the shop. Luckily tweeter parts and labor are usually pretty cheap. (~$60 parts and labor)

I find that if I set the attenuator at about -5db or so, that the tweeters are holding up ok. The tweeter is crucial to the clarity of the cabinet. It sounds really muddy with the tweeter turned off as any other speaker cabinet will.

When all is said and done, I love these cabs. I would recommend them to anybody looking for a lightweight cab with articulate clarity. I recommend two of them if you are in a loud rock band (meaning your bandmates have no concept of *reasonable* volume). Just make sure you don't crank the tweeter.

Construction	90%
(Well built. I have had a few problems with tweeters. They seem overly-senst
ive to large loads. I don't recommend turning the tweeter attenuator above -5
db. All-in-all a very good cabinet.)
Clarity	100%
(Perfect clarity when combined with a good preamp/amp.)
Volume	85%
(I use this in a loud reggae/rock band right now and I find that it is really
a lot better if you have 2 of these cabs. 1 will do if you're feeling lazy bu
t don't expect nearly the same output from one. With two - you will crush eve
rything else on stage if you have a good amplifier rig.)
Portability	100%
(Light. The dolly handle allows you to roll and carry other stuff while. Fit
s in Miata passenger seat with bass guitar.)
Customer Service	50%
(I've had a few incidents that I've tried to get covered under warranty and al
l I have to say is, it doesn't seem like anything is covered.)
Value	85%
(Wish the tweeters weren't so fragile. )
Overall	90%
(I have two of these and I have no plans to buy any other speaker cabs unless
these meet an untimely demise. I might consider looking at Epifani cabs at th
at point.)
