Thanks for a great review. I have a pair of these that will be getting installed in my 87 Grand National this winter, to be powered by a Phoenix Gold MS-2125. Should be around 360W+ per sub. From what John over at AE has stated, combined with what you're saying in your review here, that should be plenty of power, eh?
After reading your review, I am really getting excited to get this install rolling. Just gotta get the transmission taken care of, then I can get to work on the audio phase of the project.
Here is my overall system plan, in case you have any thoughts/input.... (you seem to be one of the ones who know their shit)
PG MS-275 (50W x 2 @ 8 ohms) -> 2 x ID HLCD (109db) (Way more power than I need, but this is the smallest amp of that series, effectively. Looking at either the CD2 or Ultra w/ full-body horns)
PG MS-2125 (255W x 2 @ 2 ohms) -> 4 x ID OEM 6.5 (91db)
PG MS-2125 (720W @ 2 ohms bridged) -> 2 x AE IB15 auto version (91db)
I really wanted to make sure I had solid mid-bass to match up to the IB15s in order to provide a solid transition to the horns. As a result, I keep finding myself worried about not having enough output in the sub-bass range. The more I hear about the IB15s though, the more I think the 720W should be plenty enough output to provide desirable overall freq. response at the highest output levels I would actually want to listen to.
I suspect that I should spend a good bit of time vibration damping my trunk. A Grand National is no small car, so I imagine sealing the trunk up as well shouldn't pose any issues due to limiting available airspace?
I agree with some of the others on this thread too - I think these are very handsome drivers. Nothing fancy, but nothing ugly about them either. They look like elegantly designed, very functional subs. Well, I have to admit, the magnet is a little ugly, but nothing a little polishing can't overcome. Of course, I have been away from car audio for a long time. The huge and/or exotically styled drivers so often seen these days were far from common in the early 90s.
Thanks again for the review,
