I find it interesting to learn that a few of the classic 2-way monitors also share the sealed cabinet design. LS3/5A and Yamaha NS10 for example. Although I don't think either of those designs are up to snuff with modern 2-way monitors.

Hey, those look like my drivers....

Try a bigger cabinet with a port with the Seas. The port might be a bitch to make because of lack of space. That will open up the Seas a bit - give it some and dynamics, even in the mids. The Seas are extremely inefficient once baffle step is considered, so it will never be a super dynamic and lively sounding driver.

Another consideration if you don't play super loud... drop the x-over of down to 1600Hz. Those Scanspeak tweeters will handle it. They are very slightly horn loaded after all. Those are one of the best tweeters I've ever heard.

Yes, you mentioned that. After a fair bit of tuning and damping, I've accepted that the sealed cabinet sound will not go away. A compromise I'm willing to live at this point.

I'm going to order one of these flat packs and stick the Alpha 15A's in them. I'm guessing those drivers sound a lot better in a cabinet (less excursion) than on an open baffle.

BTW, the 305 is still way better than any headphone <$1000. Highly recommend for headphone lewsers who are interesting in getting into real hi-fi

Goddamnit. I have been struggling with the realization that speakers are actually fucking awesome. I was lurking the wide world trying to figure out where to start. I remembered chatter about the yamaha hs5/8 and the jbl 305/8, then I remembered the negmonitor thread, and then I read this specific line. There should probably be a thread dedicated to "so you've decided to buy  a gun speakers..."

Here's the response 1 m away from baffle. I pulled the monitor away from the wall for this. A lot more bass than indicated when in position. That's pretty much what I'm hearing but take measurements with grain of salt as I'm doing it with large diapraghm condenser with cardiod pattern. Apply inverse of FR of what's below in your mind.

At listening (where my head is) position with subwoofer engaged:



Can't use ARTA here because of crossover needs.
