speaker wiring and passive crossovers

Well that a long topic title :lol:

My woodworking skills are ok , but that's where it ends , I am building a new PA for disco use.
The subs/bins contain the following.

2 x bmsspeakers.com/cone-speaker-compression...woofer-introduction/

Both are only in 8 ohm versions.
So the first question , a passive crossover , I was thinking along the lines of 40hz HPF and 200hz LPF.
so wiring the speakers in parallel that would give a 4 ohm load , correct ?..

The tops are 2 x 8 + comp driver.

8" drivers bmsspeakers.com/cone-speaker-compression...driver-introduction/

Compression driver bmsspeakers.com/cone-speaker-compression...ession-driver-intro/

so what about a two way crossover 200hz HPF and 1.9khz HPF ?

As all three units are 8ohm , how would these be wired to give a total load impeadence of both tops and subs of 8ohm ( everything running off one amp) , of have I got this wrong ?
am I making ant sense? :lol: :lol:

Not nice running passive between bas and mid top. The componants would need to be very big in the power handling dept, ergo not cost effective.
Two amps, or a three or four channel one and an active crossover.
Maybe a little lower than 200hz as well. Tony Wilkes will advise

+1 on running active crossover between bass / mids. You could get away with a single amp if run in mono, 2 bass drivers in parallel at 4ohms, mid highs (passive) in parallel also at 4 ohms. An investment in a berry ultradrive active crossover now would give you so much more functionality for hi / lo pass filters, eq, limiters and delays.
