shelf port vs. oval port?

[jzucker]

Is it my imagination or are shelf ports less focused and more boomy?

[rpsands]

It is your imagination.

[billfitzmaurice]

Boomy response has little to nothing to do with the port. It's usually the result of a cab that's too small for the driver. The port would only enter the equation if the cab is tuned too high.

[jzucker]

not my imagination. Every guitar or bass cab I've tried with the shelf port (Mesa, Avatar and several others was unfocused and muddy)

[rpsands]

Ok, so you asked a question, got an answer that disagrees with your preconceived idea from an expert in the field. Then you say that your anecdote about what, four different guitar brands trumps science. Right.

Clearly, shelf ports make all cabinets boomy. It's why the Genz Neox212T is such a boomy piece of crap, like fEarfuls and Bergantino AE410s and every other piece of junk with a shelf port.

The fact that the cabinet was unfocused and muddy was due to design aspects other than the shelf port. The fact that these cabs had a shelf port is purely coincidental.

Sheesh man. Did you forget your anti-depressants today?

It's more like he didn't like your attitude. But don't worry; your next post will explain to us all how he did forget his anti-depressants and that your attitude's just fine.

Definitely your imagination. As Bill stated, their are other factors that lead to a boomy, unfocused response, the most likely being an undersized cabinet.

[jzucker]

Any comments specifically on the avatar neo cab? That's the one I noticed it with recently. Maybe coincidental but compared to even my cheap epifunky 2x10 the avatar 2x10 is not very focused and is muddy.

Attitude? I just stated my thoughts. Can we stick to the subject instead of attacking ?

Not sure how sophisticated Avatar get with their port tuning. I get the impression you get the same cab with various drivers, so possibly they are disagreeing.

Sorry amigo, but just reading what you wrote, it looks like you had an opinion already, weren't really asking a question, and got defensive when someone disagreed with you.

That said - it's very possible that the cabs you heard were boomy and unfocused, and it's also possible (indeed, probable) that those characteristics were due to other design features of those cabinets - the fact that they all had a shelf port was not the critical factor.

You asked if it was your imagination and then someone who happens to be an expert in the field (Bill) said yes, definitively scientifically factually it is your imagination.

You then proceeded to say "No, it isn't." Based on anecdotes.

[Mr. Foxen]

Also, to change tuning of a shelf port, it is woodwork, and not practical in a ready assembled cab, but round ports, you just fit a different length tube. So if you had a stock of cabs and changed speaker, there is more scope to altering the cab to suit.

This thread has been scrubbed down and re-opened.

As there was plenty of participation in behaviours I didn't like, I'll not infract anyone, now.
If have to come back for further moderation and cleanup, they'll be plenty of infractions to go around too, k?..

(ps: don't read anything into where I cleaned and where I didn't, as a lot of this took place offline. thx)

I'm a happy Avatar B210 user. I run my basses through either a BDDI or VT so I don't experience mud with ANY of my rigs. Okay, I do with my Peavey 215D that I loaded with Madison Knights. That was before I became a TB member and was enlightened of the fact that there is more to speaker design than merely magnet weight and watt rating! I'm saving my pennies for a pair of Kappa 3015's.
