3 Cubes is a little on the small side for those subs.

I had a 3515 in 3 cubes. Id try to get closer to 4.

ok i think i can swing a 3.95 cubed box

 

[btnhfan 5,000+ posts]

Even better.

Basically 3 is the absolute min reccomended size by DD.

They DUMAX very poorly since I do believe they are even-hung to get more BL. They work great for raw SPL at tuning since they will take gobs of power without damage. And they will *move* a good bit, just not linear. Although I would hesitate to recommend them over other subs in their class for a daily application since linear displacement IS going to be important for you deep sub bass information.

The one DUMAXed there is I believe evenhung, or very slightly overhung. The current 9500 has around a 1.8-1.9" coil IIRC with a 32mm TP, so xmag should be around 18-19mm. Still nothing exceptional, but about 50% more displacement than the older version.

Yep, as much respect as I have for 9500's, I would never use one daily. Sure they can do it, but for that application, there are much better choices.

too late //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

but, me and 80inches talked about alotta stuff (amp and power wise) and i think that we can make it work with ~2200 daily.
