So? how sound your eminence big ben speakers? I have to put nex speaker into the same cab as your.
Hi, I finally decided to swap them in my 2 1x15 Sunn cabinet to use them with a Solarus head.
They are a bit more low mid speakers since they are guitar 15'' speaker and they have an easy breakup that gives the throaty dark tone.
I needed to build a real bass rig with the 215 so I've put some real bass speaker Legend CB15, 300w each instead. These are made to handle my punisher P-bass low as AEAD, they still need some breakin but they keep getting better with a massive low-end and they can get out some cutting mids depending how you eq your instrument. on guitar they're good to shake the all drum kit...haha.
In the end, if you use the 215 for guitar the Big ben could do a great job. hope it helps.
