ok so i need to meet you in person to know your skills with the language.

and a question for you. i have asked it eearlier on some thread i think.

how can i TA my front stage with the sub? my HU cant do TA. is there any active or passive circuit i can build to add delay? i think its quite difficult in passive but it can be done by taking the active route. im desperate to do it honestly. navinji, i think you are my best hope.

cheers

I thought that TA was perhaps only required for stretch limos or trailer homes.? Could someone please enlighten?

there are both passive (often found in lodspeakers and used to align the tweeter with the woofer) and active circuits that can delay (I think I saw some on Elliot's pages - LBM is the Google Meister).

TA is used both in home audio as well as car audio.

Clip I would suggest to get the HU as fast as possible becuase you can do the TA from it. Making a DIY will be a tough job as the components will not easily avalable. Do take me wrong sense I am just suggesting.

I am thinking of shorlisting the amps for IDQ15"d2v2(100-600W),can some one share the power range i should look for to shortlist the amp.The sub is in sealed enclosure.

What is your budget ?

Gill · 22nd December 2007, 00:24

LBM, i am thinking to plan and save according to the AMP amount but it should be around 25k!Bur firstly i should be clear what power range should i look for?

low_bass_makker · 22nd December 2007, 01:32

you can go for anything like 500-800 rms range. Higher the better as you will get good head room for the sub to play clean.

ScarySkulls · 22nd December 2007, 09:17

A Dual 2 ohm voice coil Sub = two options for you.
Either series mode i.e. 4ohm
Or Paralled i.e. Nearly 1ohm.

Keep the above two in mind while selecting whatever Amp you want.

And yes, anyone with any idea on approx pricing of following amps?
Kenwood 9103
Audison SRx 1D
Steg K2/01 or any other suitable one.

Since you are having a 4 or 1 ohm sub the Steg K-Series would be a issue to wire. So you can go for Qmos Series 220.2 it will give 730 watts at 4 ohms perfect for your application.

Friends what u suggest:-
Option1-A two channel amp 150*2@4 ohms n 500@4ohms bridged
OPtion2-A mono block 500 @4ohms and 1200@1 ohms.Class AB amp
Option3-A mono block270@4 ohms,640@1 ohms.
Out of these which could be the best option for IDQ 15"

CHeers!

Option a would be under powered and same in the case of option 2 also if wired in 4 ohms and over powered when done at 1 ohms.

The best bet is the option 3.

LBM bai ji what if one sets' gains to bare min on 1 ohm in option-2 just asking if it can be done without stressing the sub!
I think i should be looking somewhere around 800w!!!
