Amplifier Query

cooldude1988765 · 3rd February 2008, 01:03

Hi I need help in purchasing an amplifier for the mtx TP112 speakers (SPECS: MTX Home | Pro-Sumer | TP112 ) I am looking for a cheap amplifier (stereo) to adequately power a pair of these speakers. I am using a crappy home stereo receiver at this moment and not happy with the way it sounds. The speakers can sound way better.

Also i need help in getting a pre equalizer at a later stage(First an amp if i am not satisfied with the overall feel of the sound, i will get an equalizer so that i can mess around with the sound curve.) Are the dj amplifiers cheaper and more powerful ??

Need help desperately
Thanks in advance

i was wondering if any of these would actually workcheers:. Really need the audio gurus here

The speakers have 92dB sensitivity. So I guess any resolving 20-25 watter should be enough. You don't need tonnes of power to make them go loud. Look for a cheapo tube amp on audiogon.

cooldude1988765 · 3rd February 2008, 20:50

Only 25watts will be enough ??
I am using a 200 watt stereo receiver right now am i giving the speakers sufficient power ???

Another important factor for the amp is that it can run nonstop for extended period of time (2-3days) without any overheating problems. My current amp lets me do that ( i really dont care for it now, its so old it might burnout any day soon).

I was looking for a 2speaker system that can make a small sized room (15ftx 15ft to be precise) to sound like a club with clearly defined bass and mids. I know the mtxes dont look like they can even produce mids but they do.(lets leave it there dont get me started on how they sound.) I listen to house/electro/dance basically music with a lot of bass and mids with a touch of the vocals and the highs. Got these speakers (el cheapo offer from a friend at what i thought was ridiculously cheap) as a a starting point just to play around and see what i feel was lacking.

While i am at it i was wondering if a usb sound card(think i need one of these real bad) on my thinkpad would make any difference to the overall sound feel. The thinkpad is the main source of music and the music does feel lacklustre from the thinkpad compared to the other asus g2 that i rarely use with these speakers.

My ideal setup would have

this

track play in all its glory (Will sound weired to most). Note of caution , if you do end up listening to the track watch your bass from about 30secs into the video.

Well you need higher power only if you want it to be insanely loud. If you listen to trance/house which has tonnes of bass, then get a higher powered amp. But then again do be aware that not all watts are the same. A 100 watt amp can cost 100$ and can also cost 100,000$.

Any NAD or Marantz amp will do better than most of those amps on that page.

cooldude1988765 · 3rd February 2008, 22:52

The NAD doesnt sound much better than the sherwood i use. I was considering dj line of amps just because of the power numbers that they offer for the money being spent.(they used a power amp at circuit city and it did sound a lot neater than what i get now) I am a college student so dont have too much of a budget... Have to work with what i have

...

More than insanely loud i need moderately loud (abt 80- 85db) neat sound...... i really am at a loss of words here describing the sound.

EDIT: Well i heard the track again and felt that speakers were not fast enough to match the bass line.

Your needs seem to more club/dj than home audio. If so the AA/QSC/Crown amps (dont know about Crest) you listed will work. They need quite a bit of ventillation as the fans suck in a lot of air and you should not restrict the flow of air. I think Low Bass Maker has one such amp for his home. PM him and ask.

cooldude1988765 · 3rd February 2008, 23:28

Navin sir you see my solution is another problem too. Because i want the music to sound as defined as a club's but at a more reasonable volume (my neighbours complain way too much about the volume already).

And was also wondering what you thought about the usb sound upgrade is it going to be worthwhile ??

low_bass_makker · 4th February 2008, 11:28

USB sound card will make difference but more on the quality part.

I was using American DJ amp it was giving 600 x 2 at 4 ohms. I was driving the subs only with that amp.

cooldude1988765 · 5th February 2008, 22:39

I was wondering if this would work ??? It gives out 600 watts rms at 8 ohms in bridged mode. (perfect 2 speakers at 300 each and impedance at 8 ohms).
I was wondering if the amp is worth $200 and would there be a noticeable difference.
Are these amps reliable because i never heard of them before. DO they run cool enough for 2-3 days non stop ???

low_bass_makker · 6th February 2008, 11:17

I think it will be you will need to give him open space so that it can easily dissipate heat it generates

cooldude1988765 · 9th February 2008, 11:40

the amp i was looking at was rated as 600W @ 8 ohms bridged and the speaker is rated at 300W max at 8 ohms. can i connect 2 speakers in bridged mode ?? will the impedance stay the same ???

How are you going to wire the speakers Parallel or series ? The final result will depend on that.

cooldude1988765 · 9th February 2008, 12:01

I do not know sir which way do you recommend i wire the amp, and also i was wondering how these connect to a laptop audio jack ???
