OK, I know I'm going to regret this but...................... Any suggestions for a replacement for the BSB12-100 while retaining the BSB 100w plate amp ?? I've run the Avia sweep and find it rolls off fairly quickly from about 35 - 30hz. I was pleased enough with the overall response, there's a couple of dips in the overall system, but nothing dramatic. On Saturday while trying to improve its set-up, I also noticed that the driver makes a fairly pronounced "buzzing" noise during the sweep - while watching movies it's only really noticeable during the opening scene of AOTC (when that blooming huge silver spaceship make its approach to Coruscant,) I checked out everthing - whether the wire was vibrating in the enclosure, air escaping, driver vibrating against the baffle - all to no avail. The driver and the amp are sealed using weather strip stuff. I ran the sub with the driver out face down on the floor (not at high volume, needless to say,) and the noise is clearly coming from the driver itself - It looked to me as though it's running out of excursion (like it's hitting the capability of its travel). I was a bit disappointed, TBH, because the thing hadn't been running for more than about 3 - 4 hours overall, and I didn't have the "gain" on the amp up more than a little bit past 12 o'clock. I don't run my sound system very loud in any event. Turning the gain up sees the driver moving quite a lot - looking very "odd" to me (like its "flapping"), but then I don't have a lot of experience to rely on.......... Watching stuff today, (the Fast and the Furious Superbit - the DTS track was brill - I could feel the exhaust noise and the air pressure form the cars whizzing past against my chest...... I haven't tried U571 or K19 yet......) I didn't notice the same noise, but I didn't run the sweep again - I'm anxious not to do any damage. It's a bit of a bummer because BKelec are on hols until 19 July - Has anyone got experience of how good they are at sorting things out when there's a fault ? As I indicated in my other thread, I'm not a fan of over-powering bass, and if it performs OK over the next week or so I'll probably let things as they are..... but if it niggles me I know I'll want to do something about it. As ever, all and any advice would be appreciated............... As far as a possible alternative speaker is concerned, I'd like to keep the enclosure and plate amp............ and would prefer not to graduate to anything exotic (read expensive.....) Thanks............... Sean.
