Looking at some of the other subs:
The DIY XXX Ported monster comes in at 116@20hz and so does the DTS-10 kit.
The PB-13 Ultra comes in at 110db. So I think you're probably right. 114db sounds a bit more accurate considering the OS output is more as well.
Is it generally agreed upon that the GH would have more than the OS at 20hz?
Sounds like the best is yet to come MK. 247 to 125 should be around 6 more db of headroom...not like you needed it before!
Your build is done? Link please...
So, wrapping up the JTR ported/horn subs max output estimates (for the S1 and S2, we'll just use the UXL as reference):
Cap 2400 (20hz) = 114db at 20hz or 3.1SI
Cap 2400 (15hz - plug for 20hz model) = 102db at 12.5hz or 2.9SI
Cap 2400 (17.5hz) = 112db at 16hz or 5.1SI
OS 120db at 20hz or 6.2SI
If we agree, I'll update my Estimated chart on the first page.
Hmmm, good feedback.
Maybe you're leaving 2 dbs on the table with the EP4000 compared to the plate amp? If that were the case, it would put it at 110db which is 4.1SI. Still to high.
What if we said 110db at 16hz, and with the EP, it gets it down to 108db.
Member scores updated.
Also, I refined some of the categories from an above reference and reference output from a 'lowest frequency' standpoint; meaning you get in-room reference or above reference bass at least at the anechoic frequency listed and higher.
Look at the member scores collected thus far. Does that feel about right? Remember, it ain't perfect...accurate to +- a half star. But generally...
Also, for those member that I don't have amps listed, please let me know what you're running.
