Do inexpensive subs not last long? Any that are reliable? - AVS Forum

I just discovered that the two subs in my house have gone kaput. One is a Velodyn VX-10B and the other a Polk PSW10. Both are very inexpensive, but I was satisfied and they were good enough for me for the 4-5 years I've had them. Now, I don't know exactly when they blew, or how. That shows how little I've use them lately, especially now that I have a 5 month old girl.

BTW, I replaced the fuses in the Velodyn but it still won't work, and the fuses did not blow again. The Polk's power LED is on so I assume its fuses are OK.

Anyway, this is not about how to fix them, but rather, which inexpensive subs are RELIABLE? Or is that a stupid question? smile.gif

P.S. For those thinking since I did not notice when they blew, maybe I do not need subs, I definitely did notice the difference when I added them. Plus, I think they blew relatively recently when there were thunderstorms (though the only other thing damaged in the house was the A/C power adapter for my cable modem) but hadn't listened enough since to notice till now.

Thank you for any assistance!

Lightning strikes are hardly a test of reliability! Lightning can take out ANY gear, regardless of cost, quality, etc. Are you using surge protection? If not ... it is a good idea to start.

Good luck,

Neither Velodyne or Polk are considered cheap subs and nothing prevents a direct hit from taking out gear but good surge protection will eliminate a static charge and with that being said if its of any value protect it.

Surge protector for sure, not only the outlets but cable line and phone/internet lines as well.

What is inexpensive? $50.00? $200.00? $500.00?

When I think of inexpensive subs I think HSU STF-2 or Polk PSW 505.

Upon further thought, maybe the subs were not damaged by lightning. All the power lines in my neighborhood are underground. As far as I know, my house has never received a direct strike.

I now wonder if they failed because they are not on the switched outlets that most receivers have. Mine has no such outlets. Thus the subs power on and off based on the signal level from the receiver. Maybe all the power cycling did a number on the circuits?

I'd like to spend no more than $300, but if I can find a sub that's considered well-built for less, that'd be great.

Polk PSW 505 is a nice sub for under $300. I bought one to try out one time just to help fill in some nulls I had, nice sub and performed well considering the negative things you hear about Polk subs. And At $249 a very good deal.

Never hook your powered sub to an AVR's switched outlet. Not sure why your subs failed, but I have an 8 year old VX10 and it still works fine.

Not to doubt you, but why is this? How did you set yours up? Thanks.

They are not designed for that much load. Switched outlets are for non amplified components such as a turntable or CD player. I have my subs and devices connected to a high performance surge protection strip. Although some don't believe surge protectors work, it's better to be safe then sorry and I've found that most strips that have a decent joules rating also offer the best quality.
