Hello, if you're waiting for Tom to chime in here on this thread regarding the hum issues some are reporting with the B&C drivers I personally don't see that happening any time soon. He's so busy with every aspect of providing the best subwoofer experience possible right now and trying desperately to catch up on back orders. Phone support has been sporadic but emails are constant. He'll stay as late as needed(sometimes midnight) to ensure 99% of emails are answered that day or at worst...within 24 hours. That's 7 days/365. So again email him at [email protected]
Doing this (email) is for him the most efficient way to address each person's issues without trying to filter out any of the folks who inevitably chime in with their snide comments who don't even own a PSA product. I know most of you remember the V18s chuffing machine posts, I've owned five of them and never once experienced this issue, this is just one incident that got out of control.
The humming thing is difficult because it is directly related to using high sensitivity woofers and there's no industry standard you can use to gauge it on the production side. Tom can have a system with zero hum there at shop and ship it to 25 people, 24 of them might be fine, the 25th...not fine. So many variables in the field in terms of electricity, EMI, cables, systems, setup procedures, and on and on and on. And another big variable is just people. Some (most) could care less if the sub emits a low level noise as long as it is inaudible at their seating with the system on and playing at their lowest (common) listening levels. Others, they want a dead silent room, and put their ear an inch from the cone. Any noise at that point is unacceptable to them. To each his own I guess.................
As far as I can tell Tom and PSA is the only ID subwoofer company using the high sensitivity B&C drivers in (now) the complete line of subs that are offered, that's quite a huge and significant undertaking just like bringing amp manufacturing and assembly in house and spray booth (finishing) as well. Many competitors are still using the lower sensitivity drivers and have done so for many years.
This brings up another point: Also, right off the top of my head I'd say we've shipped close to 225-250 subs now with the B&C woofers. So if we see 3-5 guys working thru a noise issue we also have to think about the percentage they represent.
I think those are very good results when launching a brand new design, wouldn't you agree?
On another note, the B&C stuff is selling so fast that we're going to be 100% out of new woofers soon. I mean, we JUST got the whole container load from Italy 3 weeks(?) ago.
If any of you guys are the fence with a new Sub(s) purchase I wouldn't hold off much longer, getting the B&C drivers from Italy isn't a duck walk across the pond...............
Tom mentioned the price increases in both material cost (finish product) and the new tweeters for the speakers, I don't know how he manages all facets of running this business, I guess that's why he's there 7/365 and is there till midnight most days.
I know when using the 1920w amps with the Eminence drivers I never had to turn the amp gain above 9-9:30 to bring back a sub trim of -11dB, this has to be very similar when using the higher sensitivity B&C drivers thus eliminating some of the hum issues along with good cables and dedicated circuits, maybe that's why I've never experienced any hum issues with my 27 subs I've had in my home, also never heard the B&C drivers though and can only imagine the next level signature sound they reproduce, low tuned with the mid bass slam we're all used to, best of both worlds......................
Thanks for listening to long winded post.
