Hi all, I have a passive box sub that needs a new amp and am having a surprising amount of trouble finding what I need. This is for daily office music listening at low-mid volume. I'd prefer not to get a plate amp as I would have to build a housing for it. This is what I'm looking for:
Pretty basic requirements or so I thought. Here's what I tried so far:
Other considerations:
Additional products that can generate a 12V trigger, like the Bobwire or RDL audio controlled relay. Either is another $100+ and I'm still not sure whether the OSD trigger works any better than the music trigger.
I'll list a few other things here in a minute...
- ~300W RMS into 4 ohms
- Basic DSP crossover at minimum
- Auto on/off via music signal (I don't have 12v trigger capability)
- ~$600 or less?
- Quiet operation
Pretty basic requirements or so I thought. Here's what I tried so far:
- Parts Express BASH 500S (plate amp before I decided against those) -- Loud thump when turning off, I can't stand that, it's poor design and what I mean by quiet operation.
- OSD SMP-500DSP -- Currently have this and am likely going to send it back. Auto off kicks in very easily, even when music is playing. Getting it to come back on requires a LOUD audio trigger. This feature is basically useless.
