Stasys 3 MK2 VS Porn Horn V2

I know you rigged the walls with a massive 8th order bandpass with 52 18"ers

In all seriousness I see two schools of design afoot,

1) The old skool - which consisted of primarily getting the speaker right as much as possible so that no corrective EQ was required for a good sound - partially due to the fact that corrective EQ used to be prohibitively expensive. A lot of the old EV designs were spot on in this way, but things have moved on.

2) The newer skool - which seems to consist of partially designed/copied/badly designed cabs with hordes of corrective EQ to compensate for the lack of time and effort put in at the design stage

While I believe Rog uses EQ to perfect the system you can tell by his designs and his component choices that his systems are designed with the older skool method firmly in mind

The fact that you all commented on how loud and clear the Porn horn V2 was at that shootout just confirms this. Dont forget that all of the other mid tops at that shootout were not phase plugged so if nothing else, if there was not a significant amount of R&D in the Porn then it would have exhibited the same mid range droop which is almost impossible to correct with EQ as all the others.

Also dont forget that with every band of EQ you use it also causes phase shift in other bands. This explains the near perfect waterfall/impulse/GD/phase plots of the Porn.

Unfortunately the people who design via skool 2) appear to either not realise or do not care to notice this but its also part of the reason why (and you all commented on this) that the Porn blew away everything else at the shootout.

Rog.. just found this.. you have taken this the wrong way.

Adam, here we go again.

I think the one thing Rog may miss is that he sees the industry from inside the industry, an increasing number of bands and DJs are wising up to the DIY option and for them it offers a huge potential to destroy a lot of the mass produced reflex drivers in boxes that Rog is talking about in the post above.

I think with Rog releasing the plans on the speakerplans website and people like Bill Fitzmaurice, Walt and Staiper coming up with their own offerings there is a lot of choice out there for people who want to build and an increasing number of people are doing just that.

If you want to spend a bit more but have an easier option I think the Porn sits nicely in the midband price range between a good branded product and a good DIY option and offers a lot of performance at that price.

In terms of designing it takes a huge amount of effort to achieve sonic perfection but with more and more people listening to mp3s and wma quality files which are ultra compressed, IMO people have lost a love for listening to music, its just there in their lives, they dont care about the intricate details of it anymore its just noise for a modern world.

I am the complete opposite to this if I listen to digital its gotta be the highest quality you can find, and id rather listen to analogue where possible. I do wonder though, how much the population is able to discern music from sound, and talent from crap.

I blame simon cowell, under 1% of the population have the "X factor" in any field and it doesnt appear to be any of those that receive the airtime, mostly because they are tired and bitter of the whole industry... sound familiar?

Anybody got a pic of the mk1 porn horn with the metal plug???

Don't think it did, check dom's pics in 'Show off...', they're MK1's and they're abs/plastic afaik
