hey guys i have had my speakers sitting in my desk draw for ages now as i have been waiting for the right amp to come up. I have found a amp i fancy but it will only give me 100rms at 14.4v im not too confident that that is enough for the GT240's but i dont know as i have no idea of what is reccomended for them?

any ideas on if thats in their range or am i aiming way too low?


thanks in advance.

It will be sufficient. Natrually more wouldn't hurt, but it will be fine either way.

I would reccomend more power 100wrms per side is only just enough IMO

300-400wrms is what I would reccomend, but bear in mind manufacturers can rate their amps differently, what is the amp you are interested in?

more is good, but for normal listening volumes, you're unlikely to call upon more than 50WRMS.

I'd like at least about 150-200w rms usually for dyns. They get better as you put more power into them.

It is a boston amp that i am looking at, its got 100rms at 14.4v

I dont really crank volume im only into easy listening.... they are gt160 mw not 240's as i thought

i dont know if that changes anything but should they be ok?

yes that should be fine, the power will be sufficient to crank it up loud sometimes, a higher powered amp running lower is always better because it will have lower harmonic distortion, the amp will be able to handle high transient peaks and the amp will run a lot cooler not being driven to its maximum point

I used my dyns active putting 80watt rms into each driver (160watt rms per side)
I would be more inclined in your situation to find an amplifier that has sq ratings like 100watt rms @ 4ohms at 12volts with equal to or better than 0.05% THD per channel both channels driven

the 240 set comes with the 160 woofer and a md100 tweeter so you're still right =).

or are you saying you only have the woofer?

to be honest with you i dont know, i purchased them well over 2 years ago and have not used them due to travel and finacial restictions.

i thought they were 240gt's but last night i checked the woofer and it has a little sticker saying MW160GT so i assumed i was wrong. BUT now that you say the 240 and 160 share the same woofer then i guess they may be 240's.

I am aware that more power is much better, i was aiming at getting 200rms each and 500rms to my sup but i guess with age and other finacial destractions i am limited in what i can do.

the system will comprise of:

1x deph8450 ( i know its not the best but i had it sitting around)
1x Boston amp GT-42
1x JL audio w6 D4 ohm
1x set of dyn 240GT

im planning in setting it up so that the amp runs.....
channel a-100rms (dyn)
channel b-100rms (dyn)
channel c and d- bridged with 2ohm load producing 450rms ( short of whats recco for the w6 i know)

The whole system will be under power but i dont have the cash to go buy a 350/4 and 500/1 so i guess it will have to do. I dont crank the volume much at all but having said that i dont want to have fear that i will burn other componants out by giving them a work out evry now and then.

I could prob live with selling the w6 and buying somthing smaller like a w3 , boston pro, boston G2 or some other sq orientated amp but the problem is by the time i sell mine and buy another i will end up with $100 more in my pocket and a much less sub...... as goes with the dyn splits. I could prob live with some polyglass or hsk165s but by the time the finacial transactions take place i will be $100 richer but have a set of splits which are much less.

In a nut shell i am really asking if the above system will sound good IYO? or would i be better off selling the speakers and buying lower poser speakers hence giving them more power then reccomended??


sorry bout the long reply and thanks for all the response!

cheers damien.

There are numerous "240" systems.

There is the 240GT, which has the MW160 GT woofer.
Conversly there is a 240 set (and a 240 SE set) that use the regular MW160 woofer.

The GT woofer consists of a slimmer basket, and a slightly smaller magnet, to make fitting it much easier.

dont sell your w6 for a g2,

a w6 with 450 watts, will still be better than a w3 or g2 with 450 watts

^^ Agree with Charlie but -

The Gt-42 produces 2x450w at 2ohms and your sub is 4ohms, is that correct?
The amp will only produce 2x250w at 4ohms

I have a Boston GT-42 amp and a Boston G512 sub (2ohm)
Driving the sub off rear channels bridged (450w) was barely adequate so I'm saving up to get a good amp to drive the sub

I like the Boston amp, they produce more power than on specs. I am currently running my K3P set off the GT-42 bridged 2x250w and it sounds great

My opinion is you have some good gear so don't sell any of it but plan to get a good sub amp later.
Oh yeah, highly recommend to buy the GT-42!

Thanks for the replys guys looks like i will be keeping evrything then.

In regards to the w6 it is a dule 4 so it will be runnging at 2 ohms.

il let you know how it all goes once its in. Cheers!

thats pretty much the setup im running atm

ive got the 240 gts running off an alpine mrv 540 passive (around 200wrms a side i think) and a JL W6v2 off a ARC audio mono with around 650 wrms and ive got the pioneer p80rs as the source unit.

its a good setup in my opinion, plays all sorts of music very well - only complaint i have is that the sub is a bit boomyish...would like it to be a bit tighter which my installer believes is due to me not having enuff power to control the sub as accurately as i want it

hmmm i'm still confused!

Do you have a set of splits which consists of

2 x MW160 woofers
2 x MD100 tweeters
2 x Crossovers

Or do you only have the

2 x MW160 woofers??

Phat Devil, he has a set which consists of:

2 x MW160 GT woofers
2 x MD100 tweeters
2 x Crossovers

lol ok =). Its just that he only kept mentioning the woofers and nothing else. =)

Sounds unlikely to me that a sub would actually sound boomy because it's getting 'only' 650w.

I've heard a Vanadium 12 running off less then 100w (was around 1/4 of the recommended power) and it still sounded very tight and well controlled.

On the contrary, the W6 is only rated at about 400rms from memory. They means it has more then 50% headroom available to it... why should that not be enough? ARC sound great, and are known in general to be rated quite conservatively (i.e. usually put out 10%-20% or so more then they claim).

Sounds more like an unsuitable enclosure to me... either that or the sub has a natual sound that you arent a fan of.

Back on topic, I'd defiantely not replace the speakers and sub for an inferior product, just so the power handling numbers match up.

They are top notch products, and even without optimal power going to them they should still out perform lesser products that have headroom.

yeah i agree - i thought 650 would be more than enough power! ill probably have to have a look at the box again and play around with it a bit to try and get it to sound more to my liking
