Does Anybody Know Who These Guys Are?
« on: October 11, 2005, 10:53:39 am »

I was browsing aimlessly one morning and saw this web site.

http://www.grubsrof.com/index.html

The cabinetry of these guys certainly looks up to snuff, and some of their products really look for real. It looks like some unknown driver manufacturer and DDS fiberglass horns. I don't even know what places would sell these things or who their target market is.

What would it take for some small company like this G-Audio firm to gain credibility with touring professionals? Some FR and polar measurements would be a good start. But more importantly, how does a company get their products on a tech rider? Do they just need to pump customers full of "cool factor" like some companies have done with their line arrays?

sell a bunch of boxes so that enough engineers are familiar using the product.  I only look at joker riders, but when I am specing a system and my providers try selling me something i havent used, its  fairly easy to checkup on its reputation.

Well, looking at their so called "line array", they either don't have a clue, or they just don't care. It's not a line array by any stretch, just a trap box turned sideways.

Look at the HF horns. The centers of the drivers are a mile away from each other, and there is no waveguide in front of them to try to simulate a line source. Interference seems to be the order of the day.

Hi,Guys. I'd agree with Hasse on this one....Definately NOT a line array,but no worse than any other trap box tossed up there.
I bought his book. He states (rather proudly), that his first
big boxes were knock-offs of an S-4. Ther were days when that would have gotten him a letter or two from Roy's lawyers.

I agree that these do not meet line source requirements. Also check out the vs736 sub- It is a Community VLF 218 Copy!

Re: Does Anybody Know Who These Guys Are?-Another spec stretcher---

Another company that can't figure out the math.  If you look at the FB936 sub.  It's rated sensitivity is 99dB 1w.  I might believe that-maybe.  It's rated peak power is 2800watts.  Lets assume that is also correct.  That makes for a 34.5dB difference referenced to 1 watt.  The last time I added 34.5 to 99 I got 133.5.  That is almost 6 dB from the stated max output of 139dB.  That also assumes no power compression.

I guess the current trend is to add whatever number you want to your actual specs (be it 6 or 12dB) and state it as fact.

Whatever happend to the truth!

I wasted my time by looking at a couple more speakers on their site.  The front loaded 2x18" has a less sensitivity-I believe that.  However with the same power capability and less sensitivity-somehow the max output is claimed to be the same.  It must be that "new math"-or someone has been drinking the M%#$r Koolaid.

The full range boxes suffer from the same exarations, but they even stretch them further.
