It seems like an expensive, poor performing, high distortion amplifier that's severely limiting the maximum output of the PV15X, especially for deep bass. The HSU VTF-15H is hitting higher deep bass SPL with a much lower quality driver and only a 350W amp.
I actually get pretty decent pricing on them because we buy a lot of them.
I would not categorize them as high distortion? Maybe at clipping?
I think our powered CEA tests results are hardly "poor performing"?
I believe that if you look at the comparable charts, the PV-15x meets or exceeds the output from 16-100hz with the exception of 25hz, where the VTF leads by about a decibel. (In two ports mode). I believe their amps are rated for "short term," much higher than 350w? Peak power probably helps with CEA bursts a bit. The Dayton is designed for RMS power. Regardless of how you get there, what matters is the end result.
I do feel like a powered sub should be amp limited, not driver limited. Much better the limiter kick in during an unexpected LFE spike in the latest hollywood blockbuster, than to have the driver bottom out.
Other issues that led us to choose Dayton.
On board PEQ.
Excellent output in the 16hz range.
Excellent warranty from Dayton and there is actually an in house tech in the states who can work on these.
An abundant supply for years to come should anyone ever need a replacement.
I did not like the idea of getting a shipping container full of plate amps from China.
If anything goes wrong with them, they have to be sent overseas to be fixed, or worse, you are stuck with a batch of bad amps. I have actually heard of this happening to a now defunct company.
I've had only a couple of Dayton amp issues out of over 100 amps. And for those few, the company handled it swiftly and hassle free.
At one time I had set up for a bunch of amps to come from Elytone, would have even been able to get our name air-brushed on them and circuit board customization. But in the end, I went with the reliable and least risky option. There are some things more important than 1 or 2 db in a max burst test.
