What I can tell you right now is that The midrange distortion products are reduced by around 30 dB. That is a very large amount, greater than what is seen when comparing cheapo and high end drivers.

The decision is not yet made, but I am leaning one particular way at the moment - not telling just yet. I will explain the reasons when the decision is made.

Have you decided which one to go for yet and if so why?<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8689487740107692135.post-74297359358534989252013-01-21T20:04:30.025-08:002013-01-21T20:04:30.025-08:00Hi Miguel,

The mouth termination was designed for this.<br /><br />Yes - you are reading them correctly, but I'll caution that in these measurements, the angles may not be entirely correct. It's a matter for further investigation and a new improved version of my rig. <br /><br />I've updated the sonograms with gated measurements. <br /><br />Initial listening impressions have been very good. Even with a quick 'n dirty crossover it's a very natural and balanced speaker. It only gets better from here.

Perhaps I'm reading the maps incorrectly -- going by the -6db point, it looks like (from 1k to 6k) S3 was shooting for 80 deg and got 100. Granted, over a similar range, it looked like the old S2 was shooting for 90 and got 120.Miguelnoreply@blogger.com
