Fi Audio Sub Options

[97chameleonbird 10+ year member]

Building a sq system for a daily driver. 12 inch Fi Q in a sealed box with a SAZ-1500d powering it at 2ohms for 800w. What do all the options mean when you are buyng it through thier site. What options should I get. I will get it fully loaded if need be but just wondering if any of them would hurt it for daily use. Also wouldn't mind learning about it anyway.Thanks.

Why wouldn't you get the dual 2 sub so you can wire to 1 ohm and just be easy on the gains?

New Q Options for 2010!

Cooling: The 2010 Q now features a solid pole piece that allows the addition of the Helicool cooling system that will allow an additional 200-500 watts of power handling depending upon install and scenario. Bottom line this option increases thermal power handling capacity over a “Stock” Q.

P Chamfer: This is a chamfer on the end of the pole, it helps to bring the air down around inside of the motor and helps cool the coil better. It also helps relieve the pressure underneath the dustcap. Please note if you select “Cooling” this option is included in the cooling package.

High QTS: This option is for users who intend on using the new Q series woofers in only a sealed enclosure.

Spider: This option adds an additional spider to the spider pack to help with mechanical power handling and keeping the moving assembly under control.

I Heat Ring: This option is a machined aluminum ring in the gap that lowers the inductance of the voice coil which allows it to play up a little higher in the frequency range and have better overall transient response. Please note that you can NOT select low Qts and the I Heat Ring options together.

Past Q options: The 2009 and earlier Q series woofers allowed for a “BP” option which was a machined aluminum compression plug to the pole which helps channel all of the air under the dustcap around the coil for better cooling. To aid with this increased airflow we also added 6 axial cooling channels in the top plate. Along with increased thermal capacity comes the addition of an extra spider and a changed spider pack. All of these features increase power handling from 200-500 Watts depending on the application. We no longer offer this option with the 2010 Q series woofers. This is simply for reference for people who want to know what past options were offered.

I wasn't sure if that would be alright. I guess it makes sense now. I'll probably do that then.

skitzafit: thanks for the info. Looks like fully loaded is the way to go, sweeeeet

Just get the high QTS (for seal applications) and the cooling option. It's all you need.

i suggest you go fully loaded if you ever want to sell it in the future. i havent seen too many people that buy second hand fi subs that arent fully loaded. that is probably one of the first questions asked when it comes to buying fi subs

The options are their for a reason, and it gives you the option for daily or SPL, does it not? I suggest you go fully loaded

If the amp has the proper power output at 2 ohms, then there is no need to run the amp at 1 ohm and decrease efficiency.

Why would lowering it to 1 ohm decrease efficiency? I thought if the amp and sub were stable at 1 ohm then it would be fine. Also, I may be getting an Audioque 1200 instead. If I use that at 1ohm will that be fine for a daily use with the q with the full 1200w? I'm sure the q will probably be fine but not sure if its worth putting it through that daily. And like mentioned I could lower the gain a bit but is that what you meant by lowering efficiency? Thanks, trying not to sound too annoying with the questions.

well you'll never really get the full rms rating out of any amp on nearly any system

 

[97chameleonbird 10+ year member]

True. Seems the 1200 should be fine. It says with fully loaded it will handle more anyway I guess. Is that too much wattage for sound quality, or is the sq not related to watts?

Get the high qts option for sure, otherwise don't use it in a sealed box.

Yea, I'm going fully loaded, probably going with a 10 instead of a 12.
