With Psychoacoustics you may (but it is not a true gain)... but to gain 3 dB (a noticeable gain) you will have to double your power.

No audible difference between 1500w and 2000w Choose whichever best fits your budget.

Well then you should know the general doneness of your meat

The typical digital thermometer are fairly inaccurate and need to be calibrated every so often, I love/prefer thermocouples. Thermocouples are nice. Do they make controllers that have a meat probe, grill temp probe, and air temp probe so it can run it through an algorithm, give estimated cook time, and notify you when it has reached your desired temp? Hey now guys oh.. Thats what i meant by Digital Thermometers... i didn't know they were called thermocouples

5.5 Mi Biked today. 16 min 52 seconds.. not bad..

I was recommend 120 sq inch of port, and I am using 100 sqinch. Will be trying other options thou....Also how did you came to the result of 257.69 sqinch ??? Also Steve Meade is using 150 sq inch of port on a 20 cuft enclosure. So I designed it on its line !!!! For two 18's? or is that each 100 in^2? Now if it's 200 in^2 total then you're a little low seeing how 260 is the minimum recommended port area. .. but if it's 100 for both woofers then you're seriously choking the woofers off. The "rule-of-thumb" about for every cube you multiply it by 16 in^2 is extremely inaccurate and deplorable at best. Vance Dickason's method of obtaining port area, dv - is the required diameter of the port in inches. Fb - is the tuning frequency of your enclosure in Hertz. Vd - is the volume displaced by the driver (in cubic meters) traveling through it's full excursion (peak-to-peak). To figure out Vd for a speaker, find the Sd value for your driver in the table below, and multiply that number times the Xmax (in meters) of your speaker.

Wow. Do you sit there any stare at your speakers, or even the parameters as the other so called audiophiles on this forum or do you properly install them and listen to them as they were intended? I personally like to listen to my speakers, and could care less what they look like. When was the last time you could hear a speaker by looking at it? Troll stop trollin' Simply asking for the parameters over user bias is not a slap in the face for blues.. it's how the speakers will react, T/S within reason do not lie.

Looks good... except for the fact that you would actually need around 257.69 in^2 of port.. and you have almost 1/3 of that. If you were to triple your port you could expect more output.. right now your essentially putting the woofers into a leaky sealed box

i second the /thread

Put the subwoofers in before you put the top on.. then glue it shut.. make sure the wires are all wired up then finish.. You can use non harden caulk to seal the access hole if you decide that route.

Have you taken impedance drop due to playing below tuning into consideration? No, No, No. and one more No.

althread from top to bottom then all thread fro, the baffle to the back.. Best bracing you can do.

Keep the gain down and you will not blow them.. Just don't be a nut behind the volume knob.

‎9 Mi Biked today, accomplished.

Cheap, Chinese, and a few other things come to mind Aaron!

Very musical for being high output woofers. I can guarantee you will not be satisfied with the Q's output.. they are very good woofers but reading over what you've said the BL series would be more appropriate for your (vague) goals.

biked another 4.6mi Not really tired.. mostly uphill too.

Question guys... How do the AA CF mids do Sealed? or are they IB only? gotta build some door pods and not sure what to do about sealing vs not. Also what should i X them over at? and same for the Havoc Tweeter?
