Musical woofer for TangbandW8-1808

[Gammon]

Hello,

I would like to create a OB integrating 2 Tangband W8-1808, and 2 woofers connected to the LFE channel for the ±35-100Hz frequencies. All with an HC onkyo receiver, and an Hypex DS2.0 amplifier for the woofers.

I've read many posts about the choice of woofers in OB, some prefer Alpha 15'', Goldwood G1558 or 1858, others prefer lower Qts.... but almost nobody speaks about musicality, listening pleasure! I'm not fond of numbers, and would prefer speaking about audio quality.
I'd like to listen at a quite low level (almost never loud), easy listening, not boomy, clean, 50% hifi 50% HC...

Could you tell me which would be te best woofer choice in that case (15"max)?
I'm considering by now Eminence Beta15a, Goldwood GW-1558, Pyle pro PPA15....
