Need a replacement speaker for my subwoofer

[DullElysium]

So I thought I might swell try here.

I recently blew my Samson EX500 15" speaker and now I need to know what to get to replace the original speaker.

I found out online that the original speaker would be 4ohm, but I tried it with a 700watt 4ohm car subwoofer and the volume was really quiet. That made me think something here isn't right.

I contacted Samson about the issue, but I doubt that they'll reply.

Please help me.

And a link to the page

Loudspeaker driver efficiency tends to be inversely proportionate to maximum excursion (because a longer excursion requires a longer, thus heavier, voice coil assembly).

For a given speaker cone area, halving the frequency doubles the excursion needed to produce the same SPL.

From the pdf manual on Samson's website, EX500 sensitivity is 94dB SPL @ 1 W/1m. Plenty of output, but probably not at the real bowel-loosening room-shakingly low frequencies.

Most likely you've put in a sub rated at something like ~89dB per Watt (or less) -- that's a more typical figure for a speaker designed to go really low...

You could get the blown speaker reconed

Thanks for the help dudes! That clears some things up for me.
