Joseph Audio Pulsar 2 Graphene Placement & Break-In?


I'm hoping to connect with anyone (who like myself), may have owned a pair of the original Joseph Audio Pulsars and who now owns a pair of the JA Pulsar 2 Graphenes. 

I have a small listening room that currently allows for the Pulsar 2s to be 2 feet from the back wall. This worked great with the originals, however, the Graphenes bass response is noticeably more present and now with about 25 hours of playing time in, I'm beginning to feel like the Graphenes need a bit more breathing room. While they sound great where they are with most material, they're sounding a little "boomy" on some of the more bass heavy recordings.

Unfortunately, my room doesn't allow for easy placement experimentation without moving a particularly large piece of furniture. Would appreciate hearing from Pulsar owners on what their placement experience has taught them also, can I expect the bass response to become even more prevalent as they continue to break in? 

Thanks to all,

Plugging the port of a speaker that was not designed as a sealed unit is easy. However, it likely will change the innate sound characteristics of the speaker for which you purchased it in the first place.

I had the same problem with the Perspective2’s and wound up selling what was otherwise a spectacular loudspeaker. Regarding plugging the ports, I tried that too but found the speakers lost some of their magic in the process. I should note my room is challenging for any rear ported speakers and the only surefire remedy has been to use a pair of subs with low pass and high pass filtration. High passing to the monitor speakers at 50Hz completely resolved the bass node issue while allowing them to operate optimally. The SVS subs handle bass from 80 Hz on down seamlessly. Gotta love that SVS app!

High passed with built in xover in my Bel Canto E1X integrated amp. Low passed with the SVS. I Currently have the Pulsar2’s and doing the same as noted.








Oh man, that worries me to hear.

I'd worried a bit from the Pulsar Graphene issues reported in this thread that maybe this would happen between the Original Perspectives to the graphene version as well.  Other Perspective Graphene owners have been very happy with the bass performance and yours if the first report I've seen of unwieldy bass with the Perspective graphenes.

I have the original Perspectives and have wanted to upgrade to the graphene version. I have a 15’ x 13’ room with a very wide room opening, which seems to allow larger speakers to "breath" pretty well. I am also able to pull them well out from the wall behind them, about 4 feet or so to the back of the speaker. The bass of the Perspectives is generally well controlled. Though it just occasionally on some content borders on too much. I’ve read that the graphene version has "tighter bass" but also "more bass" so it’s hard to know which directly that would take in my room.

Can you explain in a bit more detail why rear ported speakers have issues in your room? Is it a small room? Or are you unable to pull the speakers well out from the wall or something?
