Item(s) Description/Condition:

Been playing with this 18" triple stack btl in a 6th order for a while in my spare time. I got the sound exactly where I want it so now it's time to move on lol.

Sub- Fi BTL triple stack D2 reconed by pure pressure audio. $250

Box- Dual reflex bandpass, all birch, double layer mounting baffle w/ roundover, 1.5" roundover's on inside and outside of port. 38"w 27"d 25" h. $250

Or buy together for $450.

Prices are +shipping. I'd rather not ship the box.

This combo is an incredibly musical setup that plays everything well. Very wide bandwidth, it crushes 25hz and still has great "kick" on drums. Plays down to 20hz with ease. Did 143+@25hz

unless i'm missing something here, this looks like a 4th order. the rear chamber i can see is ported but i have no idea what's going on in that top picture, maybe it's the reflective tape playing tricks lol

love bandpass boxes, complete steal for anyone local

rear chamber ported+front chamber ported = dual reflex or 6th order as many call it. The term 4th order implies a sealed enclosure.

thats what i mean, i can't see where and how the front chamber is ported. not important though, don't wanna clutter up the thread

I see what you are talking about.. the pics only show one chamber at a time and are REAL zoomed in so its hard to tell whats going on.. But flastrongman makes some good boxes for people who don't frequent flspl

^^^ thanks Kyle. And sorry if the pics are confusing. The pic showing the back of the sub shows a good view of the inside of the front port. The rear port is hard to make out. And this is a series tuned 6th order.
