View Full Version : 15" t line

01-20-2012, 11:38 PM
Sold my sa 15s but am looking to buy a new pairs of 15s one of these days.. anyways I build enclosures quite often and no ones mentioned any t line boxes so I haven't built one yet, but they look fun. Although they take up lots of room, it'll be in my expedition so room is very much there... anyways I can't find any with 15s. I can find examples for 8s,10s, and 12s but I'm a 15 kinda guy and this may help some others.. I doubt I've been the only one looking for these for 15s.. so anyone have any designs they'd like to share, give opinions or tricks for them? Thanks in advance :D

This one got pretty nasty. Obsidian 15 on a D9. Lol. 30hz tline (quarter wave). 9.4ft of line. 300sq in at throat tapered to 130sq in at terminus.

You could get a design for pretty cheap. Rabbit or Ram Designs would do one for you.

You could give some subs you might be interested in, I might see what works well in hornresp.

hornresp along with any other box building program is only half the battle of a proper design. Also, quarter-wave is a simple approach, and is not as applicable as you may think to accuracy. It does give great output in some designs, and acceptable(key wording) output in most, but relying on it may have adverse effects that you may not notice audibly. And the acceptance of it may have a high tolerance to errors.
Just some information that is needed for the OP to understand about Tlines.

well sorry for the long reply, I forgot I even posted a thread and I've been gone for awhile, but anyways, I just ordered a DB Drive K7 15 D4... Heard they sound pretty good and I found a steal on it so I figured I'd give it a shot.. anyways that might help with some information for the sub question :)
