Hello 
I was wondering if someone would help me choose some drivers please.
This is what I have narrowed it down to so far.
Definite - Seas Woofers L22RN4X/P x 1 per cabinet.
86dB ~ 8 ohm ~ 221mm o/dia ~86mm deep ~ 39mm vc ~ 125w power ~23Hz Fs ~ 20-1kHz range
Midrange
Choice of either...
Peerless 830882 HDS Exclusive (Reference #peer50)
88.2dB ~ 8 ohm ~ 152mm dia.overall~ 66mm deep~26mm vc ~ 64.5 Hz Fs~60-8kHz freq. range
Or
MW144 polymer Bass/mid(Reference #mor18)
88dB ~ 8 ohm ~ 142mm o/dia ~ 52mm deep ~ 75mm vc ~ 150w power ~ 45Hz Fs ~ 48-5000Hz range
Tweeter
27TBFC/G (H1212) aluminium dome Tweeter(Reference #seas3b)
92dB ~ 6 ohm ~ 104mm o/dia ~ 43mm deep ~ 26mm vc ~ 90w power ~ 550Hz Fs ~ 1.5-20kHz range
Or
Visaton G25 FFL | 8 Ohm 25mm fabric dome driver
Mean sound pressure level 90 dB (1 W/1m) Resonance frequency 1500 Hz from http://www.impactaudio.co.uk/product.asp?ref=592
...
The box will be a ported 50l tuned to 32 Hz which gives me +1 dB ish from about 35Hz to about 175 Hz and tails off so it's 3dB down at about 27Hz and 350Hz according to WinISD
I'm going to start off with a 1st order low pass at 365 and bandpass the mid at 275 to win back the low end loss from the woofer at that frequency (I’m using 2 amps) and 3650 ish – the tweeter will be crossed at 3650 give or take, I'll pad down the tweeter and it'll get more complicated from there I expect... Part of the reason to build this is so I can learn speaker workshop properly which is why the crossover is so basic to start with, yes I know I should not just guess the crossover. and I will start with cheap components for anything I don't already have so I don't waste loads of cash
Anyway. I have never used any of these drivers so I was wondering which you though would be best out of my choices or something else altogether and if you have had good or bad experiences with them.
