I still say the evolution will only work if Enduro is used. 10 seconds. 15 seconds. Whatever.

I am not familiar with that product. When referring to specific products in this discussion, please include as much information regarding the product as possible. For example, number of channels, rms power, internally bridged, etc.

I believe that allowing a maximum of 2 amps in Street A addresses the "monster amp" issue.

Please explain why you agree or disagree with this statement.

Many retailers use SPL meters (such as Audiocontrol) that do not have the ability to judge an Enduro format. Good suggestion but difficult to implement.

No, you would be limited to 2 amps maximum in Street A. In addition, you would be limited to a maximum total of 4 unbridged channels or 2 bridged channels.

Some comments regarding "blacklisting" product.

There is no question that blacklisting a product could solve certain problems. The reason we are so reluctant to engage in blacklisting products such as the Zapco amp is because...

  • A significant number of competitors have already purchased and created installations that incorporate this product.
  • The manufacturer has gone to great expense to manufacture this product.
  • The product has already been allowed in the Street Division for several years now.
In my opinion we need to look for a solution that will have a minimum impact on the Street Division as it now stands. In other words, I don't feel we should force everyone who has already been competing with products such as the Zapco amp to start all over again. I don't believe existing competitors who don't use the Zapco amp will be negatively affected. In fact, quite the opposite is true. Now, instead of being forced to purchase a monster amp, they can simply add another off-the-shelf amp to their system. They are, in effect, able to capitalize on the investment they have already made. Now, you may think that newcomers will be facing more of a hardship with the change to the 2 amp limit (instead of 1 in Street A). The reality is that nothing has changed. The Zapco amp was still legal and the number of channels allowed in each class is still the same.
Please explain why you feel this is not the case.

This does not in direct regards to the amplifiers used in street class, but is related to such.

Q. With the rules pertaining to amplifers being discussed, will there be any consideration given towards capacitor limitations?

Current rules state;

quote:
6-7e The sum total of “stiffening” capacitors in the Street 1-2 class is limited to a maximum of 1 Farad. The sum total of “stiffening” capacitors in the Street 3-4 class is limited to a maximum of 2 Farads.
Since there is consideraton for using more amplification, wouldn't it seem logical to address the capacitance ruling?

If not, then please overlook this post.

Thank you.

How about 5 or 10 separate burps at intervals of 2 seconds or so. Then average the scores and voila!...pseudo enduro. It wouldn't take that long for each competitor to burp as many as 10 times.

60 second time limit. 8 burps for average. Sounds like fun to me.

good....
this was exatly how i wanted the street amp thing...

there is only one thing left i dont like.
the most common dampingmat in street here in Europe is 4 mm thick... and that is 0.8mm too thick with current rules!... why cant u increase the thickness to 1/6 inch so I and many others dont have to rip out all our dampingmat....

Thanx...

This is a hard call to make

I would say that's good to go, now a days people have 2 big 12's and have an amp on each

There will still be a few people who spend the $$$ and get a JBL on each 12 but then you run into batt power

so I think this woudl be good

Thank you.

Sid, this is a logicat assumption. However, the restrictions related to batteries, alternators, and capacitors are all part of the limitations regarding amplifier power. Ultimately, it doesn't matter how much power your amp is rated at if there isn't enough power available for its use.

Thanks for keeping threads on-track and objective.
