suggestions , switching from TDX 15" to RL-p

[alaskanbowtie 0]

I have a Diamond TDX 15" , in a 2.65 cu ft. box, GROSS, so it's probly right near 2.25 after all dispacement. It's ran off a Memphis 1000D . Ported with 2, 3" round ports 14-1/2" long each. According to the Diamond Tech line this is at 34 hz. and it slams pretty good. BUT , it' still lacking to me! This is in an 04' Pontiac Grand Am trunk, there is more space but I need it for the kids things and my wifes. Also access to the spare tire for road trips etc. So I want to either switch to 2-10" Quality subs or 2-12" quality subs that will give the same SQ. but more output ! It does real good but is a little bit lacking in the bottom end (because of port size) . I couldn't get the recommended 4" port size in this box design, so these were the ports we worked out for this box.

I like everything I've read about the RL-p subs and there performance , sealed or ported for me doesn't matter as long as it's loud and clean, I don't want to loose "ANY" ouput ! The twelves would be the preferred sub of course for cone area but I don't know if I can port them in this small an enclosure . I can squeeze out 3.0 ft. internal volume I think but that's MAX for the trunk space I can use. SO all suggestions much appreciated ! I can add another 1000D to the other sub also if needed and have also considered 3-10" subs sealed also ? Just don't want to buy the stuff and find out I'm NO better off then I was with the single 15. ALL help appreciated!!!

well, it's going to be hard for a pair of 12's sealed, 10's ported to get any louder then what u have. u will go up in cone area, so in theory, it's possible. (with the 12's).

a pair of the rl-p 12's would be awesome in 2.5ft^3 net sealed, off just the single 1000d. and in the very least, u will sound better (most likely, i've not heard the tdx) and be as loud. i don't think u'll lose any output. and i'm pretty sure u'll gain bottom end! the rl-p's love to get low!

hope that helps a bit

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

kent makes a great suggestion,

if you want to go ported maybe we can help with the box design

Yeah that would be great I can give you the dimensions, I think I can cut out the rounded part that goes through when the seat it down and get a bit more , how much do i need to port the 12's ? internal volume ? I figure if it's small ported they can handle more power and thus the second amp. I'm actually going to go with Zed Audio amps here real soon when the new bigger amps come out, a couple months

I will go get the demensions of what I can do and see if this will help you. THX for the help ! Oh a TDX is in the same range as a XXX or a 13w7 .

OK here are the demensions, I'll try to make it understandable it's like a 2 piece box the front is wider and taller than the back but only 4" thick , the back is angled and the front is flat . So box from the back is

34"wide x 14-1/2" high , top is 6-3/4" , bottom is 12-1/2"

(remember the back is angled like hatch back box and solid , flat)

Now the fron section is open right now with these demensions .

basically the front section is wider and higher but only 4" deep , here are the demensions

38" wide x 16-1/2" high , x 4" deep and all measuremnts are outside built with 3/4" MDF .

It's like 2 boxes screwed together , then the inside piece of the front box cut out to match the opening of the rear of the box to make it all on chamber. This allowed me a little more room by going higher and wider in the front , granted it's only 4" deep but every little bit helps. So this is as big as it can be and I'm hoping I can get the 2-12's in there ported . I'm not real savy on the porting calculations or the volume of an abnormal box if someone could help me out . I wish I could draw a picture of it for a better understanding. If you have a ph. number I can call and try to explain it better. THX

I went out and did some more looking and this is as big as I can make a box to fit with the sawzall and still use the spare Demensions are as follows

35-1/2" wide x 16" high x 11" top and 16" bottom , with the back angled and the front of the box facing the rear of the car flat.

This is 3.59 cu ft. gross with 3/4" MDF . Can i port #2 , RL-p 12's in this size box ? I cant get it any bigger.
