    I’ve had some struggles with the Verus tweeters and need to know what the most likely cause is. I purchased a set of Verus Forte towers a while back and was powering it with an older Sony Receiver, which was rated at 120W x2 at 8 ohm 20-20KHZ. I was listening to my music at a pretty loud level and I blew one tweeter on my speakers. The tweeter was replaced, and I upgraded to a Pioneer Elite SC-07 Receiver rated at 150W x2 at 8ohm 20-20KHZ. An audioholics review confirmed the power supply actually met these measurements and then a few months later I blew both tweeters simultaneously, once again listening at a loud level. Both tweeters were replaced and I figured I was probably working the speakers too hard.

    So I upgraded to the Grand Verus Towers and bought two Emotiva XPA-100’s putting out 250W and used the SC-07 for a pre-amp. This setup worked flawlessly for a year but a few months ago I, while listening at a high volume again, I blew both tweeters simultaneously again.

    I starting to think that the VGT’s can’t handle the volume of music I sometimes like to play them at, (or they have a tweeter design issue) but a google of VGT and tweeters doesn’t return much results so I’m thinking the tweeter design is fine. The VGT’s are rated for 300W, but since they are 6 ohm, my amps should have been putting out more than 300W, (assuming they were maxed out) when the tweeters went. Normally, I would think that the amps distorted and killed the tweeters, which I would remedy with larger amps, but I’m not sure if these speakers can handle much more power

    Does anybody have any advice for me, this is starting to become a drag, and the wife is second guessing the speakers I told her would last us a decade.

    Any luck, or additional information on the tweeters? I believe I have just encountered the same problem with my Verus Grands, which are powered by a Denon AVR3310CI. I was listening to music, for approximately 5 hours, at a moderate volume when all of a sudden I lost my highs on one speaker and then by the time I walked into the other room to investigate I lost the other. I initially thought it was my receiver, but after shutting down and testing again the next day, I still have no tweeters/highs. These speakers have been amazing and Aperion customer service has been great throughout the years, as these are my second set of towers and a complete 7.1 system filled with Aperion’s. This was the only information I found on this problem on the web so thought I would reach out to see if there was a fix/solution.

    I have had this same issue with my Intimus 6T towers and 6C center channel for several years now. I have had at least half a dozen tweeters blow. I have an Onkyo TXNR905, plenty of clean power. I have tried everything under the sun to correct the issue. Right now, I am sitting with three blown tweeters again. All three are out. Debating what to do next. This is a problem for sure with tweeter design and higher power, higher volume.

    We are very sorry too hear that you are having issues with your tweeters. It is very rare for the whole front stage to fail due to a defective tweeter. In some cases, we have seen an electrical spikes in clients systems too a simple amplifier failure that would cause a full frequency disturbance, that could potentially cause too much distortion and would result in more than one speaker driver to fail at one time. To help you best, we would recommend that you send us an email @ customerservice@aperionaudio.com so we can help troubleshoot and get your system up and running again! :) The Guru’s are available Monday thru Friday 8am – 5pm PST, and can be reached at 888.880.8992.

    Warmest Regards,

    My guess would be clipping it is actually much rarer in my experience to blow a speaker with to much power 99% time it has been because of clipping have seen it several diff occasions with friends gear and personally had it happen once but kind of learned to have an ear for it have been able to avoid it for 15+ years now

    Looked up an article explaining it pretty well here is a link if u want to have a look

    Very good point Kevin. It is especially tougher with streaming material as the quality can vary so much, and have greater differences in db ranges in terms of output. A song that is not recorded very well can require someone to turn the gain up higher then we normally would and increases the risk of clipping.

    The art of refined listening is something that you develop over time, and will help you to notice earlier signs of distortion when approaching reference levels and the possible clipping range.

    Thank you for your insight.

    Regards,
    Michael
