Generation X

Can anyone tell a big dfference buy switchin from eD19ov.2 to FiQ18 or Fi Bl18 in terms of sq and overall output? Question# 2 iv'e notice that eD19ov.2 uses a single spider FiQ 18 dual spider Fi Bl 18 triple spider What heck is a spider and what does is do? btw power and space is not an issue and i will be using ported boxes.

Can someone please give me specs on a box for a BL18 please include measuremets and port displacement, ideal airspace 6cf. tuning 33hz or lower.

Is that 6 cubes gross vol. or net?

Will four eD nine.1s amps be enough power to push 4 BL 18s. Btw what is the minimum air space required ported per sub?

Space is tight , what is minimum about of airspace on btl18"? Plan B wall it.

16 square inches per cubic foot. Let's say for example that i want a box built at 5cf net. volume with 16 square inches per cube tuned@33hz. How wide should the port be and how long, btw what is the gross volume before port displacement? >

How much port area do i need?

Hey RobClay have u figure out the specs yet?

This box is supposed to be 5cf per chamber before port displacment. The ports in each section is 7x7 wide and 21" Long. the ports were at 31" long. I'm not sure what this box is tuned at or what airspace is left before driver displacement. I don't know crap about building enclosures. a local shop build it.

Meade916 you're my Hero. every time i see your work it keeps me motivated.>>> http://www.soundsolutionsaudio.com/forum/i...showtopic=23101

I heard those were eight 18s not 15s.

yeah!

All i need is the BTLs in this>>>>> http://www.edesignaudio.com/installs/images/edboxes/2121.jpg

According to Scott@ Fi he reccomends the btls in that specific size enclosure something about motor strengh and effeincy he saids. ps excuse my spelling.

I need four 18s my enclosure is built for 18s only. besides want the btls be louder on same power as BLs leaving more room for more power handling? ok. and yes. go with 4 btl 18's. you wont regret buying them and how many cuft is your box for the 18's? and what the tuning 20cubes@35HZ

X2, John had Fi BL 15's off a Sundown SAZ-3000D and did a direct swap with Nightshade 15's and they are louder. How much loud is louder need numbers dbs.

i dont, ive never heard them. but they are very good subs from what ive heard on the net. they are more expensive than the btl's though. you cant go wrong with btl's anyways. Fi subs are in my price range. sundown unhhh unhh !!!

why do u prefer nightshades over BTLS ?

X2, John had Fi BL 15's off a Sundown SAZ-3000D and did a direct swap with Nightshade 15's and they are louder. I'm running 18s not 15s

size of the subs your going to be using 18s

size? Be specific please

What are nightshades?

Two min, four max.

I only have 2 amps for now plan on using 8>>> http://www.edesignaudio.com/product_info.p...;products_id=44 Would [ 4 ] nine.1s be enough for the Btls
