I wouldn't use it. I would at least build using the same drivers used in your first build so you don't have different EQ requirements...

my first built is using 2512 so its kinda out of my price range

The reason it has low sensitivity is that it has high Mms, cone mass, 73g compared to 49g for the 2512, 47g for the 3012HO. Horns work best with low Mms drivers. That mass also impacts midrange response. It's been said here numerous times but I guess it bears repeating: buy once, cry once. Well i w...

so i was looking for cheep driver for my nex build of otop12 and i was considering grs pro 12 and then i relised the low sensitivity of these driver. I know that Sensitivity does not affect the performance of horns but a remember reading sonewere on this forum that the otop where not real horns. Im ...

Thanks Bill

I just came upon this Rockville RVW1500P8 https://www.rockvilleaudio.com/rvw1500p8/ The Qts is 0.003 out of range i know. Will it create much distortion with such a small margin? 7.5mm of xmax for 74.95$ is a pretty good deal. I was planing to build a rig of 8 t48. 2 of them are going to be 3015 and...

Pretty cool!! Thx a lot.
it's definitely a cool perspective

Thanks everyone!!

There are my reasons to bi amp. I have all the amps that ill ever need so that is not a problem. Also mi roommate is an electrician entrepreneur so i can have acces to all his cheep deals for all the wire that I want. Being on a budget I would rather put the money on better quality component than on...

So i was reading online about bi amping and one of the advantage is the reduce interference from the low to affect the high. my question is does it will afect my sound if i have a single cable with 4 connector going to my tops? ?

It’s a thread revival but….did the grs driver survive? Sure did with the limiter on. But i swapted it for my 3015 and it definitly give more punch. So i cant say on the long run... Ill make 7 more t48 in the fall and i plan to put GRS in 6 of them. We will see from there. Sorry for the late respose...

I have a pair of 2512 and i was planing to put them in a pair of OTop 12 JArray so they would fit in the trunk of my civic. I changed car so i was considering to make a pair of dr280 insted. One of te reason is because i belive that the dr are more resistant to rain because everything is sealed up....

I have to say that even with a cheep ass driver and shitty placement (I dont have the wires yet), it sounds amazing! Cant wait to put it in a corner with the 3015. Thanks bill for the great plans

I just went back and read through some of the conversations we had earlier this year. Don't you also have a 3015LF you can put in the T48? Running both drivers in Hornresp indicates a maximum SPL at 40HZ with the GRS 15PT-8 will be approximately 112dB. Max SPL at 40Hz with the 3015LF would come in ...
