cubic footage vs watts ???


Recommended Posts

Okay, so I built the enclosure for my two Dayton 15" HO's, to have 7.50 net total (3.75 cubes for each sub). Works great, and so far as I know, I have never bottomed these subs out, on any note, even on those few ef ups, when I accidently maxed out my volume, or bass controls or something stupid.....

But when designing this box, I did tell the tech guy that I'd be running just shy of 500wts each to them.

Now, someday in the future (near ?) I hope to be bumping up my sub power to about 2000wts (1000 wt RMS each) They are only rated at 800wts RMS, so I know I will have to be smart with them.

The question is, is it possible that they might bottom out running 1000 wts, where they would not bottom out running 480wts ?

If so, it will probably be fairly easy to mod my box (take up some space) to bring it down to 7 or 6.5 cubes, then adjust my port length accordingly...

Just curious if you guys think that might be neccessary ?

Thank you,

Fish

Personally, I think you'll be just fine. Drop that new power in there, go see steve again and the SMD DD-1, get gains tuned, and rock out. Youll only be overpowering the subs by what, like 20 percent or so....I think itll wang out just fine... Actually I just did some googling, and saw a couple reviews of those subs... one fellow said he was running 1 in 3.75 cubes after displacements, putting over 1k rms to it, and he was super pleased with his results. Again, I say go for it, I think itll work out great.

Thank you Big.

Yea', I know 3.75 cubes per sub, is a little more than usual for most 15"s. I was not sure if the factory tech guy suggested that because I was not hitting them with too much power.... OR, because of the design of these subs (very tight suspension) but I suspect it probably has more to do with the latter. I forgot to ask him.

Anyway, my box is pretty freaking big... nearly 10 cubes, before sub, port, and bracing displacement ! Fit's like a glove.... errr, a condom though ;) LOL

Who the hell needs rear seats in a truck, anyway ? ;)

I like that set up a lot Fish, that's a way better view than I got in the vid when you were at Steves shop. I dig the 6.5s (?) down low, good use of otherwise wasted space. Man, if you ever come to Ohio, me and my son got a couple sweet little large mouth holes we could let you in on, lol. Did a lil more reading, general consensus sounds like those Daytons arent terribly picky about the size of their enclosures, so thats more that tells me you'll be fine. Post up a vid once you drop in double the power, cause your shit was bumpin pretty darn good in the vid I saw.

Thanks again Big. Those are actually Dayton 8" mid-bass drivers. I'm grabbing from 80hz, to about 250hz with them, which really takes a lot of strain off of my component mids up front. I love 3/4 way setups {mine is 3 way active + 1 way passive, between the mids and tweets}. Heck, if I had the $$$, I'd probably be crazy enough to try a 5 or 6 way setup. Much more difficult to setup, but if done properly, all the speakers work so much easier, with such a narrower range to reproduce.

Yea', it does pretty well. I know there are a TON of guys here with louder setups, and more bass.... but from an SQL standpoint, my setup does quite well :)

In fact, I'm getting ready to go beat on it a little bit right now ;)

Peace,

Fish

Port area and placement mean more than vol.

Just food for thought
