Why isn't the Ampeg 8X10 ported?

#23
I don't work for Ampeg, but I am very respectful of their gear. If I wasn't bonded to Peavey, I would go Ampeg, all the way. Anything with SV___ in the title is usually a winner, but that 8x10 of theirs is a behemoth, as someone noted the mobility of said cabinet.

If you haven't had the chance to play through one: do it! You will NOT be disappointed. That enclosure can take AND give a massive beating, and despite the lack of porting (a feature I am very fond of) brings the destruction in spades. If I wasn't up Peavey's toosh, I would go Ampeg SV Head / 810 Cab all the way.

hmm.... not sure if you want to seal up speakers that large.. would probably cut back the lows on you, and could, in theory, damage the speakers......your very expensive, you really love them speakers.
Porting allows the speaker to move to it's full extension...... the volume of air inside the cabinet changes as the speakers move in and out. Smaller speakers displace smaller air volumes, larger speakers displace more air......makes sense? Ok. That's not the WHOLE story, but it's hopefully enough to serve as a warning.
So, using large diameter speakers can cause issues in sealed, small cabinets. Sometimes. I personally destroyed an EVX18 by trying to see how it would do in a sealed cabinet..... in other words, I wrecked it, my bad. The same driver, in the same box, but WITH a carefully tuned port...is a death monster. Oh, and I think that early SVT 8-10's may have been touched by the "volume of death" fairy at the factory, but maybe not.

you can indeed seal up 2x15 you just ned to have a larger cab :) to have enough air inside the cab to circulate my car used 2 sealed 15s (I know its different systems but you know) but the bass on sealed cabs is strange it comes all around more then ported ones.

...which is pretty much irrelevant to this discussion. :p

Meaning: sometimes wrong is right. Underpowered tube amps, for example: they're wrong to those who care about musical reproduction because they color the sound of the instrument. However 98.3% of guitarists value the coloration that comes from amp and speaker distortion.

The Ampeg 8x10 is still one of the most popular bass speaker cabinets even though it's designed wrong. Likewise, I absolutely adore my Bergantino NV610 - another sealed array of tens that's designed wrong, but in a much better way than the Ampeg 8x10. :ninja:

Ive got a marshall VBC810 speaker cab, its an 8x10 thats also sealed, IMO it seems alot better built than the current ampeg classic 810, but still with that awsome sound

Sealed and ported cabs offer different tonal options, its like asking why do people still make 1x18" speaker cabs etc etc, its to offer variety, and with the ampeg 810, as people have said, its a big part of thier sound, so why change it

Didn't the V9 cab come first? It was ported. Either way, they designed a cab that wasn't ported, then they designed one that was ported, and then went back to the sealed cab. Was it all just a happy accident the they didn't put ports in it? Did they forget to cut out the holes one day? Where's that guy who works for Ampeg? He should know. WHY?? WHY??? WHY ISN'T THE 8X10 PORTED?:rollno:
