15" Type R - Quick Question for those with Experience...

[MisterGrubbs 5,000+ posts]

Doing a small build for a friend with a single 15" R on 750 rms.

First, even though I know it's more than plenty I'll ask anyways - that is enough for daily for the 15" R correct? It should push it fairly close to it's limits if I"m not mistaken. Not saying it has nothing more to give - simply stating that it will not gain much output with more power/it'll fry on music with much more.

Secondly, 3.5 net too little? Figuring around 3.0 for the sub at 34 after displacements.

I appreciate it. I noticed where Skip did four 12" R's in his AB500.1 in I think it was 6^ft(maybe?) and it seemed to have worked well, so I can only assume 3^ft would be sufficient for the 15.

Should work fine, especially with the 750 rms going to it. As for the enclosure, that should work. I'm sure you could've gone a little bigger but the 3.5 should work out great. Good luck.

What I'm asking is whether or not the sub still responds well to the roughly 3^ft. According to everything that I know about the R's I need to be giving it more than 750, but on music? I'm afraid the sub wont go much more for daily beating. Considering it will be in a less efficient enclosure I think 750 is reasonable...

Edit- Actually no. Less efficient enclosure. I'm not thinking too well. Skip or someone who has some experience with pushing these woofers - maybe Tommy - - - will the sub handle 1200 RMS per 15 for a daily beating? Enclosure will be a tad small as stated... Will it thermally handle it?

750 RMS is just fine. At 1000W RMS you need to watch how you play it because it will get smelly easily. So 750 should give you a bit more head room.

Thanks, gotcha.

They like roughly 3.5 though, correct? 3 would be a bit rough I'm assuming...

the best output i've had out of a type R is 4cu ft @ 33hz.

750 is enough, but i would give it more around 900-1000RMS

1000+RMS is when you start to lose sound quality for loudness.

Appreciate it all.

4.75 cubes tuned to 35 hz, would get loud.

 

[azimuth 5,000+ posts]

and 1000 watts on a 15 type R would work fine.

I liked 3.5 @ 30-35hz for insane lows imo

I swear, I see the term "Type-r" in this thread every single day.

i personally think they need more than a 750w rated amp, but whatever. mine sounds just perfect with 1500w.

id like to see a larger box volume as well, but meh. it should work pretty good.
