Multiple speakers, or 1 pair? Help me.

Loud front stage? Uh, yes. For over 15 years I have been building sound systems in cars, including installation and testing. I also design and test professional sound reinforcement systems. and I design and install home audio systems.
Having more power is great, along with high power handling, and high sensitivity. why waste power?

IMO, if you want to be loud, buying cheap inefficient car audio speakers is the wrong way to do it.

Well it was hard to tell by some of the crap you were telling him. So you've never installed dual mids/tweeters and had it be louder then a single set?

Who said anything about cheap/inefficient speakers? I'm suggesting PA stuff with a very high dB sensitiviy rating...

is someone really trying to cal out hope? dude he is an acoustics engineer, it says it right next to his name. he knows his stuff.

You only gain 3dB by adding a second identical speaker with the same power. Buying speakers that are more efficient will give you more output. I would consider dual midbass, but I would low pass them around 250Hz so I didn't get phase interference due to the separation. As a result. A dedicated midrange for a 3-way front stage is needed. That can help or hurt your goals.
I vote buying a better 2-way comp set. Something with much higher sensivity. Midbass requires airtight seals and adequate driver xmax.

I'm not calling you out ,I'm just curious i noticed you said "only" 3db... isn't 3db effectively twice as loud to the listener. I know other factors come into play but Like you said db is a logarithmic scale. In the RF world 3db Is quite a significant increase.

I do agree with going with a better set of comps. I use to install those things all the time and always thought they lacked in the low end. I ran a set of the dB coax in custom sealed door pods and later upgraded to the Polk momo mm6 mad a world of difference the point of distortion was well beyond my threshold for pain.

Hard to tell by some of the statements he makes. I've built plenty of LOUD front stages, so I know a thing or two about them...

2 Crescendo 6.5's and an XST per door will keep up with low 50's on bass no problem....and the prices are right. The CA 6.5's have strong midbass for a PA type driver...
