Do we really need anything more than 8" woofer and 1" tweeter for medium size room?

I have AZ Adagois ...two 6" transmission line .they sound killer.fantastic  speaker for the bucks ..mine are on 1.5" audiopoints( starsound)
I must confess i do have a sub it gets some use ,but not all the time 30hz down ..

I humbly disagree with the statement concerning anything under 7" i have 2 6.5 underhung drivers transmission line design and they are inpressive .earth shattering low end no ..but i dont want that i want a nuetral linear sound and again i back it up with a sub 30ish down
Respect..

The stand mount adagios jr. are two 6" and they are amazing! imho. i have the floorstanders and love em..I couldnt imagine a 10-12" woofer in any speaker for me anymore .i had ADS  something 15" yrs ago with 2 10" they were ok for the times.Bring the low end if needed with a single or two good subs.(Although i am oftem perplexed on this forum why people rave over very "inexpensive subs but yet spend 10k plus on spkrs).. good subs make the difference to me within reason for your setup of course.And a good 10"  or two 8" tucked away properly will bring that bottom in fo' sho' ...I feel like an ad for room treatment but that is one of the bigest changes in my sound i have ever made in low end 

Ya thanks inna trying not to make waves ..
Respect i still say if i had the bucks jl then after that it gets real pricey spkrs would be az cresendos again just measly 6.5" drivers lmao .. Unreal for 20 k retail 15 on the market 

X2 on show me the music .
What constitutes affordable? I will say it till im blue in the face there are numerous spkrs with smaller drivers that are beyond killer . I have had probly 40 pairs of spkr in my yrs . Again my cerwin vegas in the 80 would peel your face off audiophlie nada . Kef,infinity,polk,logans,ads,ar, maggies,proac etc. etc rel velodyne hrs sunfire 8-15" subs etc . Jazz progressive rock and Rock mostly,guitarist arist for 30 yrs . I have adagios in my audio room 2 6.5" underhung transmission line floor standers love them . Sunfire hrs12" 1000w sealed spiked sub . Rarely turn it on treated room . Earth shattering bass no, bass hell yes. Room treatment and eguipment play a huge roll . 500-700 bks does not make a world class sub lets get what the goal and budget are first . A serious 12" driver alone is 500bks if you want to rattle the walls go big if you want accurate ya better be ready to drop big bks if your talking audiophile quality. Jl is the mark imo for the bks around 2k for a 12" . I would rather have two 10" jl audios then dam near any single any size sub until you start talking serious bks 5k up each .classical music generally goes much deep then rock as most of you already know

My room is roughly 2010 cu ft "they" list is at med here 
3ways can be quite pricey when done well imo .. 

Bingo .. 

Im 13.5'x16'x10'. 
4 gik traps two low on corners of sprks wall 4' from spkr long wall two high behind my sofa one 24x42 in each reflection wall  1 12x42 above my large curtain window behind me.. Money well spent . Took My low-end to another level . All spkrs and sub on audiopoints 

X2 tim 

How big was dumbledor's wand lol
.. Give me clean and accurate smooth and open. Subs are a dime a dozen..one of the great later addition so much in front imo

Eric i beg to differ ... I have adagios two 6.5 underhung transmission line . They share different frequency i have had probly 40 pairs if spkrs in 30+ yrs . There killer and go to 30 hz ribbon tweeters 2way 

     What i was getting at is i believe two smaller drivers are more accurate then one massive 12"  imo. I believe my spkrs produce great bass ,placement is big but better then some 10" ive had .. Moving massive air no .But transmission designs works well  my ole dcm time frame 2000ripped they were small multi driver transmission lines too . Jmho if low end is lacking  40hz down let the sub do that hard and specific work 
respect..

    x2 eric,
      It's always a preference thing.I have had and was a maggie salesman i had smg 1,2.3a 3c 1,6qr .Biamped ,cj krell,tandbreg,luxman etc all i mean all benefited from a sub or two.I had 3c biamped tube top cj with two sunfires 8" in a treated room it was killer.If i put ac/dc on well not so much again nothing beat my ole' cerwin vegas with 12" pushed with my bridged crown 300s for that when i tryed to break windows as a younger man.My love for smaller drivers came with the ads i had two 8" then DCM (transmission design,highly underated spkr)proac 2c man i loved them with quicksilvers and  subs too...(almost always sunfires )
      That being said the newer trend toward single driver speakers intrigues me.I am very interested to hear the emerald physics with there 12" the big zu are great too.
 Again just me but all being eqaul in a great room smaller usually means more acurate thats why planers kick ass but need to be reinforced down low. 
 Until you break out the A.E black card then all bets are off.Unforntunatley my A.E card would be black only if i spray painted it.  ;-)

Number 2 with two subs :-)
