November 27th, 2008 06:55 AM #2Dba 300 RMS itong 1502D..Kung itong SUB na ito pag mailagay mo sa tamang vented enclosure kahit isa lang masmaganda itong pakigan kay sa dalawang na sa seald at sa box na kulang sa sukat..if space is not a problem dahil kailangan mo malaking enclosure sa isang SUB (4-5 cu/ft at naka tune to at least 33hz)..Maynakita ako dati dito sa provincia namin it was more or less 6k b4 Im sure marami dyan sa MAYNILA..(eg. Banawe) Amp wise I will always go for more power (RMS) and can handle low impedance..(1 ohm or 2 ohm stable)
JBL GTO 10" Box tuned to 34hz sounds very clean

November 27th, 2008 11:38 PM #4Im not pretty sure if Ifinity is the best SUB for SPL..I compete with SPL but I have'nt notice someone's using it..But the quality of the product is the same with JBL both Infnity and JBL are under HARMAN KARDON. But then again it depends on how you design and tune your box..I have a friend using 2 12" TARGA with a proper BOX design and tuning it sounds amazing.. Find "newbie set-up" by JASPER28 Ive posted some pictures on there with 1 15"..... GOOD LUCK!

November 29th, 2008 07:16 AM #8Kung gagawa ng ported box need to tune it to a specified frequency na gusto ninyo..kung gusto nyo musical tune it high..kung gusto ninyo magandang low bass ang lalabas sa sub tune it low..I know it is easy to say it but PHYSICS needs to be applied..Concept: Kailangan "BIG" enclosure..(eg.1 12" sub around 3 cub/ft including displacement or the recommended size for the sub from manufacturer)..when tuning size of SLOT/ROUND will matter..and the length of the port (SHORT for High frequency..Long for low freq.) But, if space a problem A SEALD box would be just fine if dont want it complicated..

Oh okey, I think I know what you mean. You're saying about "internal volume " calculating the overall external dimension of the box (length X width X height) and will vary depending the woofer you select too.
To tell you, building a box its not easy since there are two MAIN CHALLENGES in designing and constructing a sub box, making sure it contains the proper volume of air, and controlling the box resonances that will otherwise compete with the sounds from subs and "color" its sound. I a know a book that could help some box builder on how to built a proper box; "The Loudspeaker Design Cookbook" by Vance Dickason.
Again, sorry for my ignorance I dont know that they were talking about "Sealed box volume (cu. ft.) and Ported box volume (cu. ft.) referred as Box type.
