Car subs just sitting around should I use them for my media room?

3 15W6s for a HT sub, that should be loud as hell, given the right amount of power. An old friend of mine used to have 3 of those in the hatch of his ford probe running off a soundstream amp and it knocked extremely hard.

It'll be loud... at 50hz. Poor ol' 30hz won't be near it though.

i think 100+ DBs will be ok at 30hz

I knew when I made that post my point would be missed.

100dbs at 30hz would be plenty... I'd just worry about the high(er) SPL at 20hz higher. My goal here is to spotlight differences in what I believe a home theater sub should do vs. an audio sub should do.

I'm sure the JL W6s will play plenty low enough given the right box design. I just think that using 3 of them in a single box would be overkill for a HT application, unless the room was huge.

Here is the spec sheet in case anyone cares.

dual 6 ohms. (w6) dual 1.5 ohms. (w7)

what, they've never heard of normal amps that have 8, 4 and 2 ohm ratings?

guess they want to sell their own amps.

The idea between using dual 6 ohm voice coils with the old W6s is they wanted you to use a trio of them since they can be wired to 4 ohm. I have heard a few systems with a trio of W6s and they sounded really good.

That was my point. You can make them play low, but that's gonna be a HUGE box. Again, the OP asked if they'd be a good choice, and imho they wouldn't be. I'd actually suggest keeping one for the heck of it, selling 2, and using that $ to buy a good driver designed for HT use (since he's using the sub for "90% theater").

the only reason I was wondering if they would work good is because I have a new sounds splinter RPL-15 and I could not make up my mind if I wanted to use it because it will take around 10cf for one 15" sub and I was thinking that I if I could get the same output with these subs for around the same space or maybe alittle larger for more output it would be worth it.

Guys thanks for your help. annunaki that is for one sub correct. I was messing around with WinISD and the closest I can get to that freq response with the three subs is 18 cf tuned to 20 hz with a 4.02" X 1.5 but I think that I will have a lot of port noise. Sorry I am still trying to figure the program out. I plan on using a Ber feedback destoryer as a EQ so maybe that will help.

That is tuned to 20 hz. For 3 subs you would need one large vent or three vents, of which the length will change.

I would not suggest putting all three in one enclosure, but rather each one in its own enclosure, placed properly in the room to balance the output. Then add an eq to balance the response, and it will outperform a more expensive "theater" sub woofer. In all reality, you could have ruler flat response from approximately 20hz-80hz at over 100db. You would just need a good eq.

The sub itself is pretty linear considering its age. Not nearly as nice as the new W6v2's or other new drivers but fairly decent.
