no, thank god! it was just a 12" TC-1000 / Epic. Good little driver, plenty loud for my small loft.

I don't add one on my sealed HT sub, then again, I made a mistake once with the amp maxed out and now I have a voice coil ring dent on my metal dish cone Still works fine tho!

Looks nice! I bet they sound fantastic!

I tend to think its a glue problem, or primer problem.

Hard to tell what that might be, best to return it if you can? The noise may be coming from the motor or voice coil. The phase plug won't likely be making any actual noise itself, but any number of things could be wrong with that driver, its very hard to tell sometimes what exactly it is.

Any small issue with glue or primor can lead to failure. Its a bit tricky and takes precision. Hopefully Eminence can get those fixed for you

Welcome! Are these new drivers or did they fail after some time?

Could be room issues. Its pretty easy to stuff your ports and get a sense of what a sealed box sounds like. The larger box volume won't negatively affect the midbass at all. Only really increases efficiency down low. Just make sure to turn off your high pass filter once you seal it... and go easy at first! But what you really might just need it to figure out if you have some standing waves in that room that negatively affect the bass. Just move the subs and see what happens. I would also consider getting a higher efficiency 18" driver and just switching that. But before doing anything cos

Gotcha Charles. Glad you like em! lets see some pictures

Old thread! Yes @Charles the dual 4" ports will have a measurable advantage over the single, even with flaring. PSA subwoofers are interesting to me, it feels like they lean heavy on the driver and its motor and squeeze it in a smallish box (not every sub they sell is small) but many of the B&C drivers they use could gain more from a larger, box, however there is something to be said about how capable they can still be in a reasonably size boxed for home applications. Its kinda cool actually. What is the TV1812? I see V1812 with a slot port? that is ~6.1 cubic feet or so while the Rhy

I would not expect it to be significantly different than the 4 ohm. If anything, a bit better (in the direction of less inductance that is.) Reason for that is you typically drop wire cross section going from 8 to 4 while keeping the same number of layers. The gaps on the 8's are normally tighter as a result.

good to know!

Which is more blinding for you? the forums or db.com?
