Default Plate amp opinion

I intend to make a sealed subwoofer for music, I'm looking for a plate amp no more than150usd among these three can you give your opinion please .

1- Bash 300w can modify bass boost
2- Apex senior can modify bass boost but with less choices I think, can connect the main speakers have 6db high pass circuit (I do not know if it's any good)
3- M&Sound VX-1250 I think can modify bass boost.

if there are others please tell me.

Sorry for the bad English.

Best regards,
NS

Have a look at the OAudio version of the 300W Bash plate amp - there have been lots of very favourable reports on this version

There is also this Dayton amp that may be worth a look

What type of enclosure are you planning on using? Bass boost is more helpful with sealed enclosures as opposed to vented. So I would look for power per dollars with low distortion as your main objective. The bash amps I have worked with have been great so I would go with the Bash.

You could of course push your systems Qtc toward the high end....perhaps approaching 1.0 rather than the 'standard' .707 .???

Bass boost wouldn't even be on my list of concerns with a plate amp, or any amp for that matter

The CV amp from apexjr is a real deal if you live in a 230V/50hz country (like Portugal).

untitled

Otherwise, I would buy the apex senior. Should you ever need to service it, or modify it, the Apex senior has full schematics, and a board layout. It is also made by the same company the makes the M&K (and at one time about 85% of models). I would avoid the Bash, no service data, and too complex for the average guy to work on.

I've got an apex senior on the bench right now (for an auto-turn-on problem). It looks OK to me, especially for the price.

"with less choices I think"

Any frequency and boost is possible (within reason), just by changing two resistors.

"6db high pass circuit (I do not know if it's any good)"

It's the same as the M&K, just a couple of big electrolytic caps, I would add a couple of small film bypass caps to improve the sound. The values can be changed for different crossover frequencies (of course).

"Sorry for the bad English."

It's better than most teens in English speaking countries.

it´s a big diference, in Portugal there is a dictation "when the charity is too big the blindman suspects "
I have seen the dayton also, but the shipping cost to portugal is expensive 89usd

It's last year's model, hence the savings.

So is the M&K.
