If it's Mike you're getting it from, then I suggest you ask Mike for the best combination for your application. He knows his stuff!

And you're right about the Helix, better to over power the sub than to underpower it. At least that way you'll have some headroom.

personally, id go for dual mono and sw300

Can anyone give advice how is the sound quality of Pioneer DEh-7150 ub compare with Pioneer Deh-6350sd? Somebody offer me 7150 with RM 530 second hand. Izit a good deal?
7150 with 7-band eq while 6350,8350,9350 model all with 5-band eq. It really help a lot for 7-band?
If sound quality got lot different, i will go for 7150 even though it is second hand.
how much different for 9350 if compare with 6350?

Thanks for the feedback bro. Appreciate it.

Personally I'd go for the dual mono and the JLW3v3! HEhehe.. different people different tastes.

The thing is the output for the dual mono is slacking in providing enough juice to fully utilized the JLW3v3. Will it be a waste to use the dual mono to power the sub?

i had tried dual mono with 700rms sub.....it doesn't lack of anything

Roughly what is the max ouput for genesis dual mono bridged at 4 ohm?

The dual mono is a underrated amp. It outputs way more than it claims. The Helix A2 is a safe bet too if you're not confident.

This one might need to look at the amp birth cert.

My is written as near ~400RMS. Signed by whoever test the amp.

ya 400-500W sounds about rite

Dont have any to audit so it is really a hard decision to make. Either helix a2 or genesis dual mono. Have to go blind on this so any1 audited both before? Which is better in term of sounding and performance?

genesis laaarrrr....hehe

The Genesis Dual mono has plenty of character. Sound wise I think it's quite unique. Can't really explain it and with that sort of power it'll have no problems with almost any speaker.

The Helix A2 is also a monster of an amp, but it's very clinical, very german - plain and simple sounding. It's very detailed, but lacks character. I used this to drive my Dynaudio tweeters in the past and it was bloody fantastic. Worked really well with my Dynaudio Mids too. So it really depends on how you match the fella (A2).

Both amps are pretty good but the A2 is way larger in size (though the Genesis isn't that much smaller). Personally - since both amps are going to be used to drive a sub, I'd be pretty hard pressed to hear the musical difference between the two for a sub. Components is a different story.

Well I'm gonna use either of the mentioned amp above to drive my component instead and use my current amp, tru t2.100 to drive the sub. So what about the 'different story' hehe. Currently using Rainbow cs265 profi vanadium phase plug as component. Personally I'm leaning towards the type of sound produced by dynaudio Esotec 242. What do u guys say?

i oso have a used genesis dmx(dual mono xtreme) in good condition. Local set. Was used to drive midbass only.
U can consider dat too if u can stretch ur budget

.... Really know how to make ppl drool lar .... But I tengah puasa lar, what also cannot eat.

with pic better..keke

hi guys,

quick question, what is the difference in terms of sound quality comparing mono block amp and a bridged amp? for subwoofer of course

thanks.

if budget permits, use a CLASS AB monoblock to drive a sub.
u wont go wrong..
Cons: its pricey for 300RMS@4ohm above
Pros: u will love how ur sub sounds

listening impression: u need to experience it urself to fully comprehend why Class AB monblock is the most ideal to drive a sub
