Looks like Firmly Rooted and Sinai just had a nice comparable setup side by side, anyone manage to make it out?

Its a sect, one gets banned if questioning the 108dB 1w/m halfspace graph. Its utter nonsense to publish those numbers.
Any decent 2x21" BR or Bandpass with less volume will eat any paraflex alive. Typcially, the best 2x18" have a sensivity of 101dB halfspace, a fullspace SPL of ca. 95dB 1W/1M 30-100Hz. The designs are mostly bad, a bad design is when your driver hits xmax way before receiving its power rating specs. Therefore, maximum SPL of a driver can simply not be achieved. We are ready to organise shootouts with any paraflex design, but people are shy, nobody has the balls to bring the toys, as anyone knows its going to be very clear which design is good and which is hype.

I know the outcome and its going to be a desaster for the paraflex, but there will be no proof at least here - nobody will show up with Paraflex

Isn’t nearly every horn design ever like this? Certainly wouldn’t call them all flawed! If the db / 1w is high then surely that doesn’t matter as it’s just a different way of achieving similar levels? Tbh to me the want for getting the most out of a small power supply far exceeds the want for soaking a load of power up into hefty drivers. Maybe I’m missing the point? Not sticking up for paraflex as I am still yet to hear

It depends on the driver if it is suited for hornloading or not.
If you got the best horn 18" you can find, it will not even reach its x-max with full power applied with a correctly matched scoop. Try simulating any of the best available drivers in a paraflex, its OFF. Technically speaking, a bad impedance matching just means no real but more imaginary loading of the cone, that is the case with paraflex at certain frequency(ies), that is the case with any cone loading below the horn cutoff, the excursion will rise but no SPL, because no loading. That is the reason one needs a highpassfilter with Subwoofers depending on the tuning frequency. Applying Voltage that does not contribute to power to SPL conversion but to heat... This is a general rule that applies for all subwoofers - if you can not put in the power rating of a subwoofer, already reaching Xmax - you will end up with less SPL compared to the one that takes the power mechanically ( and more.. ) Thats it, and any paraflex is welcome to get destroyed, i have a lot of respect for Sinai sound which is the only big sound i know who stands strong with his system, making him an example. I would not even be interested at all in Transmissionline derivates, but if the sect tells the world they got 108dB 1w/1m halfspace, this can not be ignored, too many people get fooled by this idiots, its simply a blatant lie, nobody is going to discuss it as one gets banned immediatly.

I would even prefer single 21" reflex over the paramess

its no problem for me that people working with the bass they like, i have no bad feelings about paraflex at all, i like progress in any way, but the behaviour of people behind these projects is irritating. If the design is that good - why put out fake graphs and ban any discussion about it...
For comparison. This is the Gjallarhorn, a large tapped horn which is comparable in size with the CE2E. This is a groundplane measurement.  This is the measurement of the L Acoustics K28 Bass, which is near the theoretical maximum of output of a 2x18" ported Bass. The industry standard, Full space measurement. If we recalculate that to groundplane, just add +6dB to the curve. If we compare that to the CE2 groundplane measurement, we learn that 2x K28, which is 4x 18", is still 1dB less in output at 50Hz. That is a lie. We are talking about 4x 18" vs. 1x18".  This is one of the "official" groundplane measurements of the C2E:  Edited by turbo7 - 20 March 2023 at 9:01am |

Which is why some paper needs to be ignored. Don't know why some still cannot accept, not all Scoops, are the same Fane, Eminence, JBL Design, from 50s/60s/70s, and some people know to tune/change/evolve an old design, to suit modern drivers. In the real world, with all that's going on, and the number of people dying from war daily, Scoop vs Paraflex doesn't really matter. Instead of all the online keyboard warrior lark, "many" would just require a Roots Reggae soundclash/dance, with very good Systems of both types, in large venue, with decent power, and each system having "8x" sub drivers each. As speakers are designed to play music, and entertain. I'll reserve my judgement, until one of the above occurs. Edited by levyte357- - 20 March 2023 at 8:49am |
