The QA403 has scaling built in and can handle input voltages of 112V peak to peak or +-56V. This allows for testing of amplifiers upto 400W with a 4 ohm load.
Sorry. We have heaps the budget gear is often quite a lot more expensive than other places in the world.
I should also add based on NAE user name I assumed music rather than home cinema.

I was going to suggest a Richter Thor MKV or M&K X12 as an alternative depending on your budget.
Audioholics have an very good in-depth test of sealed vs ported svs with extensive measurements.
I haven't heard HSU or seen any detailed measurements for them.
You end up with cancellations and peaks ie uneven in room response. This is reduced with using a high pass filter.
What is your...
Massive hype but there is an aspect of value for money.
They are marketed for home cinema and they provide plenty of output and rumble for explosions.
But I wouldn't consider them for music.
The sealed SVS subs have heaps of low end distortion and group delay which appears to be due to massive...
