HSU amp replacement
Picking up a free dead HSU VTF 3 MK2 tomorrow. I'm assuming it's just a dead amplifier but won't know til I get it in hand. My understanding is the Dayton SPA250 is a near drop-in replacement (with some extra wood to mount it?) and then I'll have a great extra sub. Has anyone done this already - any pointers on the wiring?
The real questions are:
- would this pair up nicely with my Paradigm Servo 15 v1, DefTech STL w built in subs and Anthem MRX700 amp assuming I can get phase/volume lined up ok.
- alternatives to the spa250 amp? I have an old NAD amp that could be connected directly to the driver via an old x30 active crossover (would that even be needed if using the Anthem crossover?) - crazy talk? I'm way undereducated on what makes a good subwoofer plate amp vs a standard stereo integrated amp - the old NAD is only about 40 wpc if memory serves.
- mounting the subs into a riser for rear theater seats - If I laid the HSU on it's side, and built a box around it and the Servo to put seats on, would there be anything to consider in the design to optimize output or just rely on ARC once level/phase checked?
