Default marine 2 or 4 inch speakers

I am putting together a portable speaker with amp and power source. I already have an amp. AMP


I am trying to keep this compact and needs to be able to run all day. I am more interested in the volume than the best sound. I need this to get loud. So I need some input on some speakers. I really don't want to go with 6.5-inch speakers unless I have to to get some decent volume. They need to be marine speakers as this will be outside in the elements. I am trying to keep the cost down aswell. Seems like a tall order but I hope someone has some suggestions.

For maximum volume look for a sensitivity rating in excess of 90dB/W/m.

Unfortunately this does not come cheap.

e.g. Polk Audio DB401 (4" coaxial; 91dB; 45W rms):

These are a bit less affordable (also priced for a pair) and have 90dB sensitivity:

Thanks for the links. I actually had checked out the polk ones. If I go with 6.5-inch speakers, will I get a lot more volume and better sound? I am trying to keep this small but I am not ruling out 6.5 speakers,

The main point I was making is to go for the highest sensitivity you can get for the price you want to pay. A few dB extra makes a big difference to the loudness.

If the Polk Audio marine speakers do not meet your requirements it would be helpful if you explained why not.

A 6.5" speaker of the same sensitivity as a 4" speaker will give you the same midrange volume level, but will obviously have more extension in the bass.

This tells me what I was wanting to no. Thanks again for the help.

Impressive outdoor speakers Tim, but expensive indeed in the context of a $17 amplifier!

Have a look at Visaton, they sell pretty cheap outdoor loudspeakers in your size/cost range. Not sure about US distribution though.

Wow, those are expensive. A little to much for this project. Thanks for the link though.
