Default Help with speakers for newbie

Hello everybody

I am looking to build/buy some big and loud home speakers.
Currently i am sitting on a very cheap home made stereo system out of scavenged drivers, capable of 95db flat, probably around 300w per channel, with low frequency handling down to 45hz. My amp can handle 700w at 4ohms per channel cleanly.

I was thinking about upgrading my current system with some PA 350w speakers, but i am 99% certain that those amazon cheap PA speakers sound like garbage.

So now im thinking about building my own two 700w speakers at 4ohms. Goal is to be 105db loud, 32hz low frequency handling, and that mids and highs wouldnt sound worse than my current mission 733i mids. But i dont know what drivers to pick, or where to start at all. Budget is flexible, but i would want most bang for my buck, and preferably under 600$. I listen to metal, rock and sometimes electronic music. Would this dream be possible?

Neighbours arent a problem

Glad to hear neighbours arnt a problem.

Do you mean 105dB per watt as that is a real challenge. Or 105 dB on 700w which should be easy to achieve?

105db at 700w, i know its not much, but thats the minimum. Maybe even 110db or 120db, but its important that it wouldnt cost too much, and i dont want anything that sounds straight bad.

It seems like you're a man who would prefer quantity over quality but with your given budget you probably won't get much quantity either. But if your budget is only 600 it's hard to get what you want. As you alluded to, PA speakers from Amazon are probably your best bet.

A system with 95dB efficiency should easily be able to give you 105dB on 700W. However you will probably struggle with your bass specification. Most reatively high efficiency speakers do not go that low in frequency.

I think that may be a mis-characterization of bass response. High efficiency meaning tuning your freq. response to emphasize the ~1khz region, where as if you equalize your freq. response so that you have a flatter freq then you have to sacrifice the response ~1KHz. For example, if you take any regular speaker and artificially lift your 1KHz region, your bass response now relatively will be less and therefore seems like you don't have as much bass as before. But in reality, it's the same speakers.

The easiest way to achieve this would to be to use multiple drivers of the same specification in the design (it being a two or three way) the power handling would be greater, excursion (and hence distortion) lower, and low frequency response would be better than single drivers

The OP is asking for something very reasonable and many speakers will fill these requirements. Most home speakers are around 82 - 85dB efficient at 1W/1m (after BSC) and many extend flat to 32Hz. This corresponds to 106dB @ 1m with 128 - 256 watts - well within the OP's available 700 watts and within a reasonable range of what many speakers can handle.

Now the decision is to choose a kit or design your own. A 3-way will probably be necessary to achieve your requirements, but you may be able to get away with a high performing MTM or TMM. Your $600 budget should yeild plenty of viable options.
