project brewing in my head, challenging, but seem like a good way to try new concepts

Do you still want to try the 10" with their own amps? I'm not sure you need it or want it for that matter if you have the Titanic running.

 

[lemans23]

yeah, because i 80% sure won't use it for the main stereo, instead i'll hook it up to my xbox setup and sell my advents

 

[lemans23]

bumpity for lemans

suggestions on 8 or 10s?

How about something funky like this 8x12 from TB

[lemans23]

that could work, but are there any advantages to the elliptical shape?

 

[lemans23]

anyone else?

3 drivers, 2 of which reproduce the same signal.

I'm not entirely sure this is the correct explanation for the term "2.5 way".

A "2 way" system has two drivers (or sets of drivers) producing two distinct frequency ranges, likewise a "3 way" system has three drivers (or sets of drivers) producing three distinct frequency ranges, however a "2.5 way" design has 3 drivers (or sets of drivers) two of which reproduce two distinct frequency ranges while the third reproduces part of one of the aformentioned ranges.

I own a pair of B&W 603-S3 speakers that utilise a 2.5 way design - they consist of an aluminium tweeter, a kevlar bass/midrange cone and an aluminium "mushroom" bass driver that supplements the lower frequency ranges reproduced by the kevlar bass/midrange driver.


Here are some crossover points for a 2.5 way design (off the top of my head so don't represent any actual speaker):

Tweeter 2KHz - 20KHz
Bass/midrange 30Hz - 2KHz
Bass 30Hz - 120Hz

As you can see the lower frequencies (30-120Hz) are supplemented by the third driver - hence the system is a 2.5 way design and not a 2 or 3 way design.

Hope this clears up any confusion/misunderstanding.
