Front stage question

[matthewo 10+ year member]

well, i had my front stage picked out, until i received my midranges and 1 was blown. jbl t030 3" titanium dome midranges, very nice units. but 1 is not working. with the midranges being expensive, rare and needing a good amount of exqulization, i probably will not be buying another pair of them for my mids up front.

this is my setup right now:

zapco reference 750.2 (front stage)

boston pro 60 6.5 components (front door)

jbl t030 midranges (front door) need something new....

i am going to be running the zapco at 2 ohm per channel. so i need another 4 ohm driver or component set. i was thinking boston pro 5.25 set.. the problem is i already cut out a large part of my door panel to fit in the jbl midranges, the 3" midranges actually required about 5 inch round cutout, so i will probably need a good 5.25 set.

as far as my rear fill goes it will be a zapco 150 watt amp. with pioneer coax speakers in the rear deck, and then stock tweeters in the rear door and stock midrange from the front doors in the rear doors. with a mid and high adjustable crossover.

and the subs are going to be 4 boston pro 12.5lf isobaric firing threw ski hole

is everything ran passive?

I've heard that those boston pro60 can get really nice and loud.

yeah, all passive, may do a eq for the front stage later. kinda half to do passive when you use a 2 channel amp

I say you ditch alll the other speakers and just run the boston pro60s

 

[matthewo 10+ year member]

what about 2 sets in the door boston pro 60s and boston pro 50s

 

[James Bang 5,000+ posts]

if you want to go that route, I would go for the same size mids.

Still I would rather just run one set of the pro60s in each door.

or

2 mids and 1 tweet in each door for some nice midbass.

yeah, i see what you are saying, its always better for imaging when your running less speakers, but i just want the extra power. if i run 2 sets, the amp will be running at 2 ohm. giving 350 watts per channel, or 175 watts per component set channel. if i run 2 sets. what do you think about putting the tweeters from the second set in the a piller firing at the windshield instead of in the door?

the A-pillar would usually yield better imaging. if you do that, i suggest taking out the tweet that's in the doors.

wait your running a 2 way component through the passives and you just going to add a random midrange?

 

[matthewo 10+ year member]

no, i am running boston pro 60s, with the passive crossovers that come with them, then i was going to run another set of boston pro 50s with the passive crossovers that come with it, wire both in parrallel to get a 2 ohm load. the jbl t030 i was running before had its own internal passive crossover inside the drivers casing.

Dont do that unless you just want it to be loud and stupid. since your running passives either just run the 60's or sell them and get a 3 way passive set.

Since you cut your doors up i would do the second option

Don't run 2 different drivers playing the same frequencies...

ref 750.2 for front stage? im guessing we like headroom?

i wouldnt add the mid unless you found a 3way passive c/o to plug them in to

 

[matthewo 10+ year member]

ok with that said does anyone know of a good quality midrange, in the price range of about $200 a pair, size will probably be 5 1/4. i know its more of a midbass size, but i think my cutout if about that big, i will go measure and see if i can fit like a 4.5 or something in there. also do they make any stand alone midrange passive crossovers with a slope of something like 250hz- 4 or 5kz for the midrange?
