speaker shopping

@metman that kit does look nice. Response down to 30 Hz +/- 3db is pretty freaking solid.

Just going off specs, though, I’d guess these aren’t the best for low power tube amps, since they have a sensitivity of only 87 dB

I've looked at this kit many times, it sells out regularly, it'll be back in stock in a few days.  This kit is all Morel drivers.  Driver cost alone is $700 to $800 range...
Jeff did not use any impedance compensation on this kit, that means that it will stray upwards in impedance at certain frequencies, but it won't stray lower.  This is a protected Proprietary kit, they won't show schematics or curves without a purchase.  I have used the parts included, they are all great sounding.  I trust very few speaker designers, including some fairly well known manufactures.  Jeff is a solid designer, these will sing.

@cwright590
Which revelator tweeter are you using?

Scan speak D2905/9900-00 tweeter and scan speak 18w/4531-goo 7 in midwoofer

Hi cwright590, Thanks for the info, I took a look at these drivers. The good news is that the tweeter has a better impedance curve than most. The bad news is that both drivers need to be notched. and you would need some steep slopes and the woofer need Z-comp..  In the end, it could be very good, but it requires some crossover work. If you'd like, your welcome to pm me.  If not, I understand, I hope this helps, Tim
