lanzar opti

Im looking at the lanzar opti drive subwoofers now theres 3 diffrent ones and whats the diffrence and the one says its 3000w rms? is that for real because I have 2 18 dc xl's right now and im looking at running maybe 4 15's of these opti drives and if there 3k rms a piece i will run a dc12k to the 4 of them

Link to the one's you are talking about, or state the models.

*Edit* Nvm a quick google search reminded me of the driver model numbers.

You are wondering about the 15" drivers? Are you looking at the OPTI1533D? That's the one I'd recommend, NOT the OPTI1532Ds.

They are pretty darned good woofers for the money. They are not 3kW woofers, but will take 1.5-2kW of clean power. Search the models on the audio forums and you'll read a lot of good reviews. But take the reviews for what they are and make your decision.

They will take some good power for sure, and get loud, but from what I gather they don't like the low lows, as they are more of an SPL woofer, so an enclosure tuning of 35Hz or so is probably your best bet for daily smashing and controlling that cone. I believe they have a pretty high Fs, but that all changes when placed inside an enclosure, and it'll change again depending on the vehicle, enclosure placement even, and what is in close proximity to the driver/port while inside the vehicle.

If you choose to run 12kW to a quad woofer setup with the OPTI1533Ds I'm sure that'll be fine. 4 woofers with 3" coils and all...

With your plans and current setup I trust you have a good bit of understanding on enclosure dynamics, design, and whatnot? If not I'd happily design your enclosure or wall for you, and I'm sure some of the really good enclosure gurus on the forums would design you something killer as well. Because the woofers are more of a 1.5-2kW driver I'd design an enclosure with less than optimal volume for power handling, tuning around 35Hz, possibly a tad higher, unless you are planning strictly an SPL build? Then all of that changes of course for the enclosure.

What kind of vehicle is this going in? Do a build log! Looks like it'd be a fun project.

There isn't a 3" coil that will hold 3000w of thermal power continuously for very long. I'd suspect these would handle 3KW mechanically assuming you tune properly and don't play below tuning freq. When running that kind of power you really need to use your head and don't just trust that a "3000W" rated woofer will handle your 3KW of power indefinitely at any frequency without failure.

Yes I have a lot of experiance on enclosures, this is in a 2005 escalade and going to be put into a 2008 escalade soon this setup will actally be tuned 38hz so thats why I figure with the dc 12k amp it should be solid I was hoping but im unsure because I like to play my system for some times 10 mins stright which i could see this being a problem, but like I said if im playing higher tones would the coils heat up you guys think? I get greaty sometimes with the bass and cant control my self to just turn up the eq up lol

Oh yeah, the coils will heat right up no doubt. Inherently, 3" coils don't have the surface area to dissipate the heat that will build up properly. Unless it was super long, like an unseen WH coil lol. The coils on those drivers aren't too shabby, but they are far from great.

Even if you are not clipping at all, no matter what frequency, even if it is an extended amount of time playing that is spot on with your vehicle's peak frequency kind of music, where the woofers are physically moving the least, the coils will get hawt. In this case, it is because a 3" coil cannot thermally handle 3kW. But to be honest, these woofers will be most efficient while receiving around 1.5-1.7kW I'd assume, and they will get loud off that. So if possible while tuning your system, try to aim for amplifier settings where you are obtaining 8kW or so; or, utilize the coil configuration to your advantage while wiring up the woofers to the amplifier in order to receive the amount of rated power at a certain impedance on the amplifier, of around 8kW or so. But if competing, hell, go right ahead and wire down and give full power if you are doing a burp! Giving each driver 3kW on a burp wouldn't harm them.

Either way though, 12kW on these quartet of woofers is going to be too much for them in a daily application. But don't let that turn you away, these drivers will get loud off of less power than 3kW a piece, so it's just not needed. And, that isn't a bad thing necessarily.

If I only had a dime for every opti ive seen blown up in spl setups.
