Episode 315 - T&K Vorix 30 Ti .308 and 300 BLK Testing and LayerX Strake 9 Deep Dive (22-JUL-2026)

Today’s Topics:

  1. Sound Signature Review 6.231 – LayerX Strake 9 MP5 testing. It’s been about 3 months since you’ve seen the MP5! Welcome back, subgun friends. This is the relatively light and compact Strake 9. Hybrid designs and low back pressure – what happens when the silencer is small? Can this beat the HUXWRX Cash 9 at its own game? Technical deep dive for the report published last week. (00:10:12)

    a. Intro and recap – what is this silencer for? (00:11:59)

    b. Strake 9 general overview (00:14:50)

    c. Strake 9 silencer design and functional physics (00:17:49)

    d. Hazard Map Brief 8.1.28 (00:24:39)

    e. Strake 9 silencer performance (00:30:58)

    f. Performance Comparisons and Overall thoughts (00:40:46)

  2. Sound Signature Review 6.232 – T&K Vorix 30 Ti on .308 and 300 BLK bolt-action rifles. Multi-cartridge testing for this lightweight and compact bolt-action rifle silencer, to fully characterize its behavior. A little under 1.5-in diameter, and less than 8 inches long… yet bringing the performance? Pleasant surprises seem to becoming more commonplace in today’s silencer market, which is great! Let’s take a look at these interesting physics in this introduction to the report published today. (00:46:16)

Episode 314 - LayerX Strake 9 MP5 Testing and Listener Questions (16-JUL-2026)

Today’s Topics:

  1. Sound Signature Review 6.231 – LayerX Strake 9 MP5 testing. It’s been about 3 months since you’ve seen the MP5! Welcome back, subgun friends. Today we introduce the relatively light and compact Strake 9. More companies entering the 3D-printed space. Hybrid designs and low back pressure – what happens when the silencer is small? Can this beat the HUXWRX Cash 9 at its own game? Introduction to the report published today. (00:08:40)

  2. Listener Questions are back! Let’s dive back into Solicitation 8, answer your queries, and learn more about silencers!

Episode 254 - Dead Air Wolfman Testing and MP5 Performance Research (09-APR-2025)

Today’s Topics:

  1. Sound Signature Review 6.182 – the Dead Air Wolfman on the HK SP5 – in both long and short configurations. Prolific (and also misunderstood) submachine gun silencer. Let’s dive into the technical discussion of the data and analysis published last week.

    a. Introduction (00:07:46)

    b. Physical Characteristics (00:17:31)

    c. Technical Performance – Long Configuration (00:27:10)

    d. Technical Performance – Short Configuration (00:44:04)

    e. MP5 Suppression Performance Comparisons (00:51:09)

  2. Pending Member Research – MP5 suppression. The Quietest 9mm Subgun Silencers. We all know and love the MP5 platform. It is, perhaps, one of the most famous and refined subgun silencer hosts that we have in small arms. So, which silencers help it to perform at its greatest potential? Which have the best signature reduction and tone? Ongoing in-depth signature research that will be delivered exclusively to PEW Science Members. Thank you for your support! (00:58:35)

Episode 253 - Dead Air Wolfman Testing, Echo Zulu Defense, OSU, and PEW Anniversary (02-APR-2025)

Today’s Topics:

  1. The Silencer Sound Standard is now 5 years old! Thank you for supporting PEW Science all of these years and helping make this the industry standard for silencer sound suppression performance. (00:09:05)

  2. Big thanks to Oklahoma State University! Engineering faculty and students attended our seminar last week – a very welcoming group of people who are learning about fire, explosions, and protecting the public! A great degree program for folks that are interested. (00:30:06)

  3. Sound Signature Review 6.181 – the Echo Zulu Defense X1R556-Ti on the 5.56 standard untuned mid-gas 14.5-in barrel M4A1. Another hybrid design. Let’s dig into the technical talk for this report published last week. (00:42:45)

  4. Sound Signature Review 6.182 – the Dead Air Wolfman on the HK SP5 – in both long and short configurations. Prolific submachine gun silencer? Absolutely. Misunderstood? Clearly. Let’s do a quick introduction to this technical report published concurrently with this episode. (01:28:29)
