I know a few people have asked for more than personal impressions of an Epik Tower. Normally, I'd use all my own measurement equipment and post up results, but I was having trouble stomaching the results I was seeing. The output differences were significant in my room and I wanted to make sure that it wasn't my equipment.
So last week, I contacted Chad and asked if I could bring my Tower and PB12-Ultra and use his equipment. Chad does a ridiculous amount of GP measurements and has everything needed to properly calibrate all of his equipment.
On Friday, I took a trip to Epik with my babies and took some measurements. The measurements were taken at 2 meters with LMS software. The measurements were recorded in 5dB increments until ~10% THD was reached. Measurements were taken one after another. I mimicked Illka's procedure as much as I could.
You're probably tired of reading so here are the results:
I was happy to see that the SVS PB12-Ultra measurements have a very strong correlation to the tests that Illka ran on the same subwoofer over at HomeTheaterShack
. The results were almost identical in fact and might
allow the Epik numbers below to be compared to Illka's other measurements.
Epik Tower + A little Conquest
The (bright blue) lines are of the Epik Tower, while the (dark blue) line is of an Epik Conquest. Only the Epik Tower sweep was planned, but a Conquest was available too so I convinced Chad to let me test it too.
Unfortunately, it started to rain right as we were going to sweep the Conquest. I was barely able to get my Tower and didn't feel like paying for a ruined finish on a Conquest.
The gear was still sitting there from the last Tower test so, I hit the sweep really quick to catch it before the rain started pouring and then packed everything up.
I don't know how the Conquest measurement relates to total possible output from the Conquest, but it was LOUD and really makes me want to know how much louder the subwoofer can go!
