For 8 ohm loads...if you're committed to going with 2 ohms, you're looking at using a seperates system, no real way around that. Some sort of preamp and pro audio rackmount power amplifiers.

i wanna build 2little towers with
6 Aura NS3-193-8A1(3")

and

1 USHER 9950C-15 1inch tweeter(1")

Those midwoofers cost $20. You are going to spend $240 just

for midwoofers for two towers?

Aura sensitivity is 80dB.

Usher sensitivity is 88dB.

6 mids gives you ~ 7.78dB

6 mids wired for 5.3 ohms gives you ~ 1.7 dB

Sum of both = 9.5dB

80dB + 9.5dB = 89.5dB

That should mate well to the tweeter.

If the budget is $240 for midwoofers, why not just build a proven design

like the modulas on HTguide using Dayton RS midwoofers costing $30 each?

... because the speakers boxes are too big and you want to make small towers?

well.

yea I want small towers, its for my room(~850cu.ft), right now i have 2different computer speakers and one mini-sony system all connected to my computer...(6mids-high and 2subs.) doesnt sound right at all and it takes too much space, pisses me off..

so i wanna do 2small powerful towers to put as "computer speakers" and hopefully 1 18"sub in the back later on, and take off all the BS i have now, its for music and movies...

I agree... 240 dollars is alot for a gamble.. my line arrays were easy to gamble with, becasue the mids were only 49 cent apeice. If i were spending as much as you are on speakers i would either just buy some, or build a tested design, especially scince you dont know what your doing(no offense, i dont either)

loll

its more like I know wut I want .

I want something that would sound good first of all, Looks good and doesnt take much space ! The surround on those 3" looks way to good/beefy and will match with the room (size I have to work with)...and Aura is known for SQ with their NRT technology...also, u get wut u pay for.

So i dont really mind spending on good stuff..

The thing that is pissing me off is crossover setting and amplifier receiver all those things..

how can u know it isnt good?

 

[brandontw 10+ year member]

bad brand, and like you said...you get what you pay for.

For 300 dollars, you could get a pretty fine set of speakers, that would probably look and sound better that something you would build out of 3" aura's

This is what I would do. Think hard on how big you can make your speakers

and see if a normal midwoofer will fit into your plans. You want to use the midwoofer for normal midrange and woofer duty. There is nothing interesting

about the $20 Aura 3" midwoofers.

*sensitivity is dog at 80dB.

*Xmax is 3 mm... so?

*Aluminum dome. Probably the worse recipe for midrange SQ. The best SQ

comes from paper treated cones, esoteric cones like Kevlar, magnesium, aluminum, have

nasty breakup modes and you can't operate those up to 3khz.

*NRT neodymium magnet system - Neo magnets are cool, but a moot issue

really. Neo offer high magnetic field in smaller size than other magnets, but

we aren't concerned with magnet size are we? Given the fact that they

use neo and their sensitivity is 80dB, that tells me it's a poor design.

A good SQ recipe is to find a dome tweeter that can hang with a 2khz crossover point,

if your dome can do 1500hz - 1700 hz with a steep slope, this opens the doors to allow

you to consider the esoteric cones, otherwise you need treated paper cone mids if you want

ultimate SQ.

A cone treated 4" NSB (49 cent driver buyout from PE, now soldout) would

probably perform just as good as those Aura drivers, perhaps better.

$3 (six) NSB + $5 lacquer > $240 Aura. Port the NSB for bass extension.

That is money spent wisely.

I'm sure you can make this system work using Aura drivers, I'm sure

I could too, but there has to be a more efficient way to get the job done.

Here is the new McIntosh array using what appears to be a bunch of Aura drivers.

Sixty-Four 2" Titanium Midranges

Here's the sad part of the design -> 2.8V/1m: 89dB

110 drivers and they can only manage 89dB sensitivity.

My budget line array is rated for 104dB sensitiivity. LOL

Just because McIntosh uses Aura mids doesn't make them smart designers.

If you can 'go big', pm me for a recipe idea {TM, MTM, TMM}

A good tweet that will drop down to around the 2khz is the Morel MDT29.
