I prefer to build passive subs so I can use any other amp in the future. I am currently using an "outboard" plate amp installed in a custom made wood box. I'm interested in a subwoofer amp in a normal form factor. NHT sells one - and SVS sells the Samson. Are there others? Any recommended? Someone suggested the Crown K2, but $1400 is way to much for me.
Any pro audio amplifier, from the likes of QSC, behringer, gem sound, pyramid, crown, samson or bryston should all work. Although you will need to use a crossover or bfd with all of them. Why are you so opposed to plate amplifiers? Pro amps have fan noise...

Though prone to blow up in the first 10 minutes of using them. But if they don't, they will be very reliable, last for years, and they don't sound half bad.
I suggest you find a local PA company, and see if they can do you anything second hand for a decent price
That's a bit sarcastic for a moderator... or not? 😀
Coming from you, I see your comment this way: "If you are lucky enough to get a QSC RMX that won't blow up in the first 10 minutes, it's probably a "lemon", so it will last several years, be reliable and it will sound good."
Why everybody recommend them then?

You can get rid of that though, I know someone that replaced the fan in a QSC RMX amp so that there was virtually no noise.xstephanx said:

Per channel I have two 12", 4ohm woofers in parallel. I drive them with a GAS Grandson; 80 watts/ch into 8 ohms and it can handle 2ohm loads. I have all the SPL I could possibly want and couldn't be more pleased with the SQ.
How about a Crown K1? You can usually find one for about half the cost on Ebay. I got my K2 for $900, and I don't regret it one bit. 1250 Watts per channel into a 2 ohm load, or 2500 watts bridged mono into a 4 ohm load
I just checked and there are 3 K1's for sale and 6 K2's for sale on ebay . Higest price for a K2 so far is $825

I prefer passive subs because:
- I'm not locked in to the plate sub I choose when I build the sub
- If the plate amp fails I can substitute something else
- no possibility of air leaks from the amp
- no rattles ever because of the amp
- no controls on a sub which may be in an inconvenient place
- I think it is slightly preferable to run speaker wire than interconnect wire to the sub
So my ideal sub amp would have all the features of a plate amp in a 2U rack chassis.

now, if a person had a plate amp, they wouldn't necessairily have to build it into the sub box, right?
My plate amp is currently in a wooden box inside the A/V cabinet.
If a plate amp fails you can replace it
If it rattles, it wasn't done right.
Good point about high vs. low level wiring eh.
Personal preference.

I currently use a plate amp (Keiga) mounted "outboard" in a small wooden box. Of course if the amp fails - I can remove it and repair or replace with the exact same unit. I don't want to be limited to the exact same unit. I may want a different one. And of course they have different dimensions. What could be better than having the controls in my main rack of equipment instead of on the back panel of a sub stuffed in a corner behind something else?
So far the best suggestion I received is the Outlaw M200 1u rack mount mono amp at $299. No crossovers so perhaps a Behringer or similar could be used. It is definitely an audio-type unit compared with the pro-sound suggestions I have also received. The Crown K looks very good but $$$$.

I use an Adcom 555ii. Convection cooled, 200W into 8 Ohms, 325 into 4, 600 bridged into 8, 850 bridged into 4 for $350-$400 used. Rack ears are available; I'd bet on 4U.
I use a keiga 520 - 300w plate amp in my sub.
Yes its mounted as part of the box. -- But its got more power than I know what to do with.. makes a guy wonder what someone would do with 3x or 4x that amount 😱

It lets you combine a smaller box, linkwitz transform, and drivers with a huge Pmax to create louder lower bass with better SAF.

ahhh, I see.
No SAF to worry about here... I cant hear anything below 27hz anyway, and if I turn it up where I can feel that.. the neighbors come banging on my door (hazards of apartment living).
One of these days im gonna have to try a linkwitz.
