Tyler acoustics questions

I am zeroing in on either the Tylo monitor or the Linbrook sigs & would like to know what folks found to be the dfference in the midrange.I have a sub but if I bought the Taylos (save a thousand) what would you have to statr your sub at to run in parallel i.e I would use the preout on my RA Tempest II. I prefer to set my sub for music set at the lowest 50 Hz which seems to match it best with the quicker 6-7 inch driver with most monitor speakers .Do the Taylos do a honest 50 Hz in which case it is no doubt the better choice especially since my tube amp produces way more watts into 8 ohms than the 4 ohm sigs.(probably a better match)

The other issue is the tweeter .I see most folks lprefer the millenium a little more however I am looking for the smoothest one in the upper mids with the best rendering of siblance. My sense is the Scanspeak may be a little smoother & less peaky with a tad less presence in this area.Comments?

Thanks

Bill
