Question A500 vs EP1500 vs 240w plate amp

I am building a Dayton HF 12" sealed sub for HT/Music. I am trying to find the most affordable watt/dollar combo to drive it. I first thought about the Dayton 240 w plate amp, but was interested in getting something with a little more punch. I am not trying to break any windows, but I do like the idea of having something I can grow with.

What do you all think: would I be better served with a smaller plate amp, or go for a pro amp?

Thanks!

What is the power-handling spec for the driver? That can’t be overlooked. It’ll get you no advantage, for instance, by coupling a 1000-watt amp with a 200-watt driver. I’d suggest an amp with perhaps 50% more output than the driver can handle; that would ensure adequate headroom.

400 rms/ 700 max. I think the 240w amp would be too small, but if push come to shove, it will provide enough juice to drive the sub. I ran across the A500, which looks to be a perfect fit, but was unsure if it would be appropriate for a HT sub. Only reason I have been considering an ep1500 was because I noticed many other people using them for HT, but I would rather not have fan noise if I can avoid it.

Thanks for your input!!!

You might look into the Yamaha P-series amps. A bit more coin than the Behringers, but I’m told their fans virtually never come on when used in the home environment.

Are you considering buying the ep 1500 used? That amp has been discontinued from behringer for a while now. You could look at the ep 2000, you can get a new open box unit with full factory warranty for $249.

OK I just called Unique Squared where I got that $249 price just to make sure the factory warranty applied to that unit and they told me they were out of stock on that unit and it has now been pulled from their website.

Best price I find on the ep 2000 is $280 with free shipping on ebay.

Thanks for bringing the ep1500 discontinued issue to my attention, no idea why I did not notice that before. The ep2000 is above the price ceiling I set for myself $200(+-). Unless it is really worth it...... What are your thoughts on the A500, I have found those new for $199. Looks great, no fan; but is it worth it?

Re: A500 vs EP1500 vs 240w plate amp

Ok I will give you my opinion but let me say this first, I have just begun building subs, my first project is a maelstrom 18" in a 24" cube enclosure using the plans from this site. I have had it up and running for only 2 days now but am VERY satisfied with the sound with no EQ. I am powering it with a Behringer ep4000 bridged (2400 watts). So as you can see I am new to this but I plan on building 3 more subs in the next couple of months 2 of which will be Dayton 12" in sonotubes (keg subs) for HT and I will be using a Behringer ep 2000 to power those. So to give you my opinion, no the a 500 is not a great choice to power the sub you are speaking of building, it will work but you will have that amp maxed out and chances of running into clipping issues are very possible. One of the other posters mentioned "head room" very good advice. And if you ever have any intention of adding another sub at some point the extra $80 for the ep 2000 over the a 500 will be money very well spent as you would be able to run 2 subs off of the ep 2000. Also you are talking about using the 8 ohm Dayton HF, you could get the 4 ohm version (same price) and get 500 watts per channel out of the ep 2000. You could just use one channel for the time being and if in the future you want to add a second sub you have the second channel of the ep 2000 to run it. Remember this is only my opinion take it for what it is worth.

The problem with the A500 is that in bridged mode it will only drive an 8ohm load and only outputs 2x300 watts at 4ohms.
