Default Alpair 7 twin design vs. JBL 4312C monitors

I really enjoy my JBL 4312C monitors. Can anyone contrast the Alpair 7 twin design performance with the JBL's? I know that the JBL's are 3-way, but was wondering if the Alpair 7 design will be a competitive performer as a monitor speaker vs. the JBL's.

Cheers

Monitor can mean many things. Your JBLs are monitors, the BBC LS3/5A is a monitor. They are totally different.

You can build a VERY nice speaker with the Alpair7. IMO, a better sounding one than the JBL, but it won't play as loud, have as much bass or be as dynamic. It will be less coloured, more musical, more accurate, and create a much better soundstage.

But it is hard to directly compare them... and their prime goals serve different purposes.

Thanks I see that now. Another question...what WOULD compare to the 4312's? I want to build another monitor set but have a difficult time choosing a design?

I was never a big fan of JBLs like that so have never paid attention to similar, so i am of little help.

I'm not hip on JBL -- some folks did new crossovers for L100 which should alter the perception - here's one - dunno how much it applies to your 4312
JBL L100 Century

what are you trying to do with/experience from your monitor? what kind of spl peak does it have to do at 1M?

Alpair 7 is listed as a 70mm diameter cone

Revc= 3.600 Ohm
Fo= 69.0 Hz
Sd= 50.24 cm2
Vas= 3.48 Ltr
Cms= 913.149u M/N
Mmd= 5.456 g
Mms= 5.660 g
BL= 3.342 TM
Qms= 2.015
Qes= 0.803
Qts= 0.574
Levc= 0.0188 mH
No= 0.135 %
SPLo= 84.5 dB
Xmax= 4.4-mm 1 way
Pwr= 20 Watts Nom.

Ok, let me pose my question differently. What would be recommended for a monitor speaker where unadulterated sound is the goal? With good base response.

What kind of monitor?

Apart from that, define good bass response - do you want it to hit you in the chest, or something that goes very deep, or what?
