I will be getting 3 t3 TS 10s soon and I want to try something different, and also eliminate that need to always have my back seats flipped down for the extra 2dbs.
I am afraid to try a 4th order because I dont see how it would be better being that half of the sub is in a sealed chamber. Is it because the ported section is rather large and tuned high that it makes up for it in efficiency? Does the sealed part store some energy and release it through the cone like a ported box stores energy and transfers it out the port?
This is in refrence to daily which doesnt mean it has to be flat just good from 32-50 in car.
I have heard people boast how some extremely loud db drag vans use a 4th order but I think that is just so they can throw a ton more power to the woofers and they are peaking in sealed box ranges like 50-60-70.
The plan is to seal off the trunk completely with flat board in the ski pass and board up the rear deck, then build a single test box and toss it in the back seat before making the full size trunk version with two 8" aeros through the rear deck.
What size should i start with?
Does they type of woofer really matter as in a sealed box woofer for 4th order, because i think the ts's were made for ported.
I read that high qts is good which these have, other than that idk where to start.
I imagine the sealed section size kind of determines the mechanical power handling so if the regular reccomended sealed is .75 where should i start with the sealed section because i dont want it to be too small and not let them move at all causing temps to rise. I understand that the tuning will cause some frequencys to really load the cone but i dont want the sealed part choking them. Im trying to match the mechanical throw to the power they can take thermally which is probably 750 rms
.66 sealed/ 1.75 vented each with 32 inches of port each / 18.2 inches per cube. is where i was going to start with a slot port and test and tune from there. Any bigger / smaller? I have a ton of room to work with, this design would be about
7ft net 8.5 gross i have up to 10 gross i could use and still have trunk space.
Thanks i have tried researching but havent found anything great, and I know it will take some testing but where should I start. Also anyone who has heard or build a great 4th order tell us how great it was .
