Suggestions for amps & a subwoofer

[whizzkid_ram]

Hi Guys, Hope you all are fine..

I have just bought

1. Kenwood Excelon KDC X994 HU
2. Illusion Audio EL6.1 front compos
3. DLS 428 rear coaxials on MDF tray &
4. Noisekill damping.

Now, I am in the search of amps & a subwoofer.

My requirements:

A) The subwoofer should play LOUD,LOW,clean and tight bass, i mean even if i reach higher volume, it should play without any distortion. BUDGET for SW - 7k maximum along with enclosure. What are the subs i can get in that budget?
How about BULL AUDIO SW-12" ?

B) Coming to mono its tight on budget.

I came across this class D mono from kenwood. how much it would cost me?
http://india.kenwood.com/products/ca...03d/index.html

PS: For a new mono from a branded, decent manufacturer, i can spend up to 13 to 14k. No problem if its without bill & warranty, provided it should be easily serviceable if any fault occurs. Is there any decent mono in this price range?

C) Suggest me a decent 4 channel amplifier to drive the EL6.1 and DLS 428. Budget for 4ch amp - 10 k max

I'd be grateful from your valuable piece of advice.

Thanx & Regards
Ram.

Hey, how much did you pay for the KDC-X994? No doubt its amazing HU.
I see that you have cool set of speakers. I highly recommend rockford fosgate amps for this setup. Checkout R300-4 to power all the speakers. (fits in 10K budget)

Kenwood KAC-9103D is good. Your Bull audio 12" can handle 200W rms. KAC-9103D seems too heavy on it (It has 500 W RMS; you can count on atleast 400 W)

Why not try INFINITY REF1260W and power it with Rockford fosgate R500-1 mono amp.?
RF R500-1 cost nearly 20K. Sub another 6-7K.
 
You can also checkout JBL GTO1214 - 12" sub (350 W rms) , priced at 6K.

Hi Anil,
I paid 10000 bucks for the HU & it is bought from US of A

A) Rockford R300.4 is 50wrms rated no? the EL6.1 & DLS 428 are 75wrms/185 peak & 80wrms/120w max respectively.. Won't it be underrated?, i mean the power from R300.4 is insufficient?

B) For KAC-9103D, can i run the INFINITY REF1260? I heard from some of the members in TBHP the INFINITY REF 1260 costs 5k excluding enclosure. Is that true?

C) What is the cost of KAC-9103D & KAC-9104D, what is the difference between these two amps?

D) As i already told, for RF R500.1, i'm tight on budget. as it costs whopping 20k.

E) Is the JBL GTO1214 12" sub priced at 6k is along with enclosure?

[anil]

Yes. you are right. But, in RF 50 W RMS is really 50W rms, unlike few other manufacturers. Technically, they are underrated for the 75w rms speakers. But, I have seen them with Infinity kappa 60.9 .. they rock!

okay .. I ,might be bit wrong on price. Infinity prices often swings! I think 5K is fair. Yes you can use KAC-9103D there.

>>What is the cost of KAC-9103D & KAC-9104D, what is the difference between these two amps?

Well, power rating wise I didn't find any diff. One significant difference i found is power consumption, KAC-9103D seems much efficient!

Sorry, I don't have the exact prices for these. I guess it would cost nearly 14K.

>>Is the JBL GTO1214 12" sub priced at 6k is along with enclosure?
No. Without enclosure.

A) How about this 4ch amp JBL 1004? Are they overrated for EL6.1 & DLS 428?

A guy said 100W RMS is not continous, This is not called overrated, it's called headroom. With proper gain setting, it would be FULLY compatible.. He also added that he have used 70W speakers on JBL 75.4 @ 104W RMS for 3 years.

So enlighten me about this bro.

B) This one, JBL S644?

http://www.indiajbl.com/CarAudioDesc.aspx?ID=3

C) Which suits perfect for EL6.1 & DLS?

D) The approx. 14k price for KAC-9103D is with Bill & Warranty or in grey?

[Raghu]

Actually it is good to overpower the speakers a bit. and also since the components are run with high-pass circuitry, there's no harm even if it is slightly over powered. He is right!

And gain setting shouldn't be used to match the power ratings. Its not a volume knob. Its there to match the sensitivity. Trying to match the power may lead to distortions.

But, for sub woofer, you need to really count on the power ratings. Always find an amp that matches the power handling of subwoofers.

You can go with JBL 1004 for the speakers, its a great amp.

I would like to suggest you, to skip powering the rear DLS speakers. Just use them as rear-fills and use JBL 1004 to power front components & sub woofer. No need of separate sub amp. (Later you can add mono amp., when you can afford it)

That KAC-9103D price is with b&w. in grey you can expect it to be nearly 9-10K.

@ Raghu

A) I intend to buy KICKER COMP VR 12" subwoofer (2 or 4 DVC)

http://www.kicker.com/compvr

This SW has (WATTS PEAK/RMS)* 800/400

I would like to drive this subwoofer through KAC-9103D. which has 500W rms. Should i buy 2 or 4 DVC to drive through KAC-9103D?

B) Regarding the DLS using as rear-fills, i read in the learning section of our website as

"In case of a speaker driven directly from the head unit (No external amplifier), your speakers are not sufficiently powered. Remember that, your head unit can output the RMS power in the range of 17Watts-22Watts. Hence we recommend the speakers to be sufficiently powered with external amplifiers."

Moreover, i don't wish to put load on the HU & if i could drive the DLS through the amp, i can get full accentuation from it.

[Raghu]

Thats true. In case of rear-fill, your DLS won't be sufficiently powered. But, your front components are sufficiently powered. Rear-fill approach is known to create good sound stage, so we usually recommend it.

KICKER COMP VR 12" subwoofer is good one. You can use KAC-9103D with it.

[whizzkid_ram]

A) Won't we get good sound stage, if both the EL 6.1 & DLS are powered by a 4ch amp?

B) I came across this HIFONICS mono amp for sale.

http://www.team-bhp.com/forum/classifieds/showproduct.php/product/6419/cat/18

I spoke with the concerned person who sells, he would give this HIFONICS mono for 8500 bucks at last & he says it is in mint condition.he bought it from USA. Its 9 months old.What is the reasonable price i could expect? how could i check its a repaired or unrepaired one as he from chandigarh?

C) Should i get Impedance (OHMS) 2 or 4 DVC for KAC-9103D? could you see from the specs tab from the following link & advice me the same.

[Raghu]

Hmm... I would like to call "good sound stage", a personal preference. I have got varying reviews on "rear-fill" and "both-front-rear-well-powered".
Well, even after powering both front and rear speakers with amp., you can always play with the fader and find out what tuning pleases you.

Nearly 8K looks like good price.. See the cost for new one here: http://www.sonicelectronix.com/item_12210_Hifonics+BXi+1208D.html

>> Should i get Impedance (OHMS) 2 or 4 DVC for KAC-9103D? could you see from the specs tab from the following link & advice me the same.

KAC-9103D is stable at 1ohm as well. So, you can freely choose either 2 ohm DVC or 4ohm DVC.

[whizzkid_ram]

The older HIFONICS Brutus Bxi 1208D monoblock costs just $189 from the following link & it is replaced by a newer model Hifonics Brutus BRZ1200.1D

[Raghu]

Hey, cool combination!
Where are you getting AUDITOR RIP 4280?

[whizzkid_ram]

Raghu,

It is from the person named Ajay who deals with audio from mumbai.

[whizzkid_ram]

Guys,

A small change in the setup. I bought FOCAL SOLID 1 MONOBLOCK due to the unavailability of MTX RT501.

FOCAL SOLID 1 specs:

Nominal power measured at 14.4V continuously @ 4 ohm -1 x 300 W
Nominal power measured at 14.4V continuously @ 2 ohm -1 x 470 W
Power under 1 Ohm - 1 x 600W (SPL MODE)
