Magico Q7 . . . wow

stereotaipei, could you provide to me at least two drivers of the similar size which eficiency(measured with 1w input, not 2.83v) varies more than 7db in 50-300hz range? I have measured more than 160 diferent drivers on identical conditions, so I think I know a litle bit what I am talking about.

Q5: 86dB
Q3: 90dB
Q7: 94dB
You are right, 8dB

I see we are discusing in diferent worlds. I am speaking about main part of the speaker- speaker drivers(woofers)and there is no posibility more than 6db diferencies in low FR on same size woofers. You are talking about speakers eficienty where sensitivity can vary from arround 80db to 95db (in some cases like horns vs electrostats 75- 113db) because not speaker driver(s) determine speaker sensitivity but speaker designer -enginier. he can reduce (by changing BSC etc. ) or tilt up ( by adding more paraleled drivers, changing drivers interaction etc)

so we are both right. btw In your place,I would take manufacturer specified sensitivity values with salt and grain- unfortunately there very rarely tells truth.

Ebm, my room is rather large about I heard Q3 works wonder
in smallish room, about 4.5x6.. M room as well. My local dealer mentioned one customer who has Q3 in a roughly 4x5m room or something a bit smaller even with no problem at all. Seems that Magico is quite forgiving as far as speaker placement and avoiding boomy bass is concerned and is not very difficult to at least get a decent sound from all sort of placements but certainly if you find the right spot, I have not heard anything better near its price point at least as far as my taste is concerned.

I heard that Q5 was measured closer to 83 dB tahn 86dB somewhere. Not sure about Q3's 90 dB. My amp seems to have a bit easier time driving Usher Be-20 (90dB/1 watt/8ohms)
louder than Q3 90 dB/1 watt/5ohms.

My friend with Q5 was asking if I might be interested in his Q5 as he is considering Q7. Unfortunately I think that in my rather large room (6.8x8.2m with large opening on one wall) my Lamm will not be able to drive Q5 adequately so I have to sadly decline!

So it looks like the Q7 will be perfect in my medium size listening room driven by my 60 watt Jolida tube amp. What a relief...
