Usher Be718 seems to be good though I haven't auditioned it. If you happen to listen like Jazz and/or Classical (both Indian and Western) then Cadence ARITA bookshelf is also a nice option to consider withing the budget of 100K ( 90k Speakers + 18 K Stand + 12.5% VAT + frieght + Octroi) or Cadence Diva can be also be had by streching the budget little bit. Both Arita nad DIva are tube friendly and can be driven by an amp of even a 20 WPC one.
Dyna 52 is also very good option especially for Rock and Pop (thanks to its deep bass punch) , this can be had for about approx. Rs 60K (including stands). Dyna needs a powerfull amp which you said you already have.
Check with Prithvi of Absolute Phase , Bangalore if he has anything to offer from Proac tablets range. Monotor Audio Silver range and some B&W 600 series can also be considered. There are some good Full range single driver speakers from Audire (Coimbator) worth auditioning, though no idea about priceing, there entry level one can fit within this budget.
If space is not a constriant then I would recommend to go in for a 2 way floor stander and there are many good options available in the budget.
Hope this helps.
