Default Pass kits

I plan on ordering a number of pass kits for my speakers. I am making a 3 way system and want to use a Pass class A on the tweeter. i am crossing them around 6k - AES is 35 watts, program power is 70 watts. I am shooting for clear uncolored sound. Can you please recommend me 3 of the pass mono blocks for this driver?

a fairly safe assumption that even One pass amp will make your speakers sound like you never expected them to.

Tweeters don't need much power. Another choice could be a the ACA, designed for beginners but sounds great with high efficiency drivers.

Check out the article and kit in the store

That's because I specialize in low expectations.

I am guessing out of the boards available the f5 would be good? These are fantastic drivers - the ACA doesn't have the power I am looking for as I am trying to hit high levels of spl.

For my high mids (2 5.25s highly sensitive) perhaps the turbo - running them at 4 ohms ideally I'd like at least 75-100watts.

The low mids/lows are 10s and again highly sensitive and planning on using lfet ab for them the the subs to get as much power as possible without so much heat. The 15s are not as efficient as the rest. This is for a surround sound set up so while I plan on an f6 and possibly some tube equipment for stereo, transparency is the key.

At 4 Watts your at 113 db at 1 meter or 3.3 ft.
A jack hammer is 100 db at 3 meters.
A gas chain saw 110 db.

Youll need 5 of those woofer to keep up with the tweeter and you still have to pad the tweeter 2 db.

I can add more woofers. Or I can adjust the gain on the cross over so it is proportional. I am looking to get a min of 124 db spl out of these so I do need more wattage. I am probably going to have to use an AB design for it. Supposedly mixing and matching amps to get the right sound for each driver is a bad idea as they sort of have to be timbre matched like tweeters and multi channel speakers. That being said, can I still bias the tweeter with an A and the mids and low mids ab and have the right character? Or is it best to stay all in 1 class? From what I understand isn't every additional driver add 3 db sensitivity to that set of driver so if nominal is 99 and I'm running 2 isn't 102 the efficiency of the drivers?
