FreekDesignz Posted February 25, 2011 Report Share Posted February 25, 2011 Does a bigger cone yield higher SQ? I know SQ is mostly the box but what about the woofer? How does an 8" compare to an 18"? What are things to look for in a SQ sub? Big coil, High excursion?

hdorre Posted February 25, 2011 Report Share Posted February 25, 2011 Yes and no. One goal of SQ is to have a somewhat flat sound stage. Say you have 2 Fi 15" Qs in the back on a Sundown 2500D. You would want more mids and highs and more power for them in order to have a flat soundstage. But, say you have a DC Level 2 on a Rockford P300-1bd. Having 10 mids and 10 highs isnt what youd want, because you most likely wont have a flat sound stage..it would peak because of the mids and highs. Thats my understanding atleast Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...

OldsBoomer Posted February 25, 2011 Report Share Posted February 25, 2011 O geez SQ is NOT and i repeat NOT meant to be loud at all. I would never use an 18" in a SQ setup. I would run maybe two 10"s sealed but thats it. Your mids and high are supposed to blend very "smoothly" which mean bass isn't louder then mids and highs and vice versa.

Your mids and high are supposed to blend very "smoothly" which mean bass isn't louder then mids and highs and vice versa. aka no peaks/ flat frequency response explain to him what you mean by "flat sound stage" No frequencies have peaks, so no frequency sounds a lot louder. This could be tested with an RTA (I think thats what its called).

I would...all day long...and I used to compete SQ in IASCA (early 90's FWIW) an 18 can easily reproduce lower frequencies than a 10. sure, if I use 3 10's I can get the same effect, but as long as I keep tuning the way I do (50Hz Brickwall XO) the snap from a small sub doesn't matter. My mids make up for that. back when I was in the lanes if your car didn't FREQ at 130dB you were DQed...pink noise at 130dB or you were done...so, yes, SQ can be loud....but clarity comes first Quote Principal JTech Consulting - Leader in 12-Volt Training and Product PlanningIt's not about how much power you have, but how well you use it Link to comment Share on other sites More sharing options...
