New toys!

Audible Physics just released a new set of high end drivers, RG100.4 and RG100.6. 4" OD full range drivers. The .4 is a 4ohm and the .6 is yes a 6ohm. Specs are slightly different as the 4ohm is intended for car audio and the 6 for home. 

Rishi, the owner and designer, was kind enough to send a pr of the home variety for me to test and review. So I thought I would share the journey with you guys.

They met specs dead on, no surprise there. At this price point, they better! The enclosure model is coming in at 2.65L with an Fb of 75hz. I will be using 1/2" bb ply.

I know that I love my set

Well yeah! Rishi is now working on a lower cost version as well. 

Geoff did you measure the tweeters as well?

Ge_off_me

Yeah, not in depth though. They were pretty flat through the bandwidth.

Bunch of measurements. All taken at 1/48 smoothing, 90db at 1m. The FR and dist were taken before the port was finished. I should be doing near and far field tomorrow.

Why are the picture so small?

Probably because I grabbed them from my Facebook page and down loaded them to my phone. Didn' realize it would do that. I can repost from my laptop later.
