Sub selection

marcus555dc · 10th February 2006, 10:54 PM

The box= 2 or 2.2 F^3 (Sealed)
The application= HT/Music (blues, rock)
The amp: Parts Express 240 watt plate

The 12" choices: under $100

1. Ascendant Assassin
2. Dayton Quattro 12
3. Dayton Quattro 15

Any others I should consider? I want to stay under 100 no matter how much better the driver is! My orginal goal was 75, which basically limited me to quattros. This is for a friend and he only has $210. The amp is 120, that leaves 90ish for a driver.

Thanks for suggestions!

I have the Quattro 15" in 2.5 ft^3 sealed. I think it works pretty well for minimal cash. The 12" is no cheaper and gives up a lot of extension, so unless space is at a premium I'd stick with the 15.

Thanks for the input! What is your impression of the 15 quattro? For movies and music? How much power do you have going into it?

300 W BASH amp. The 240 would be just fine, too.

I was going to write a long review, but I haven't had the benefit of experience with a bunch of other subs to inform my opinion so I'l keep it short. With the Quattro in a sealed box I know I'm not getting the very deepest (below 20 Hz) rumbles from movie soundtracks, but I'm getting a very satisfying bottom end for both movies and music. I'd have to fix a bunch of room rattles and resonances before I'd want any more bass extension than I'm getting. I'm still tweaking, but overall it has integrated into the system very well.

I think the Quattro's a good deal for the money. Whether it will meet your needs (or you're friend's) is up to you!

Thanks sounds good. I am not sure if i should do the 15 in a 2.3 ft^3 sealed, or the 12 in 1 ft^3. Based on many of the posts i have read it seems that the 15 is better suited in a 3 foot enclosure, or 6+ ported. 6 is way too big for this application.
Would 3 ft vs. 2.3 make a huge difference? When i model the 12 vs. the 15 i get higher db's from the 12. I must have the parameters wrong... right???

Orginaly he wanted this:

But, I thought a DIY project would sound much better all around, and be fun too! Any thoughts on that sub, and would you agree that the quattro would kill that.

Thanks for feedback!

IMO, the 12" Quattro in a sealed box would roll off way too high to be a useful sub. In 1 ft^3, PE says the F3 = 60 Hz.

It would be pretty happy in 2 ft^3 vented. The overall response looks pretty similar to the 15" in 2.5 ft^3. I'd want to use a 'rumble' filter for movies or it might bottom too easily below 20 Hz.
