Studio Pro WH8 8" Woofer Accordian Surround
Studio Pro WH8 8" Woofer Accordian Surround is rated 4.3333 out of 5 by 18.
Rated 5 out of 5 by from Better than the original !!Replaced the original 15 watt woofers in a old pair of Radio Shack Realistic speakers. They have never, ever, - sounded this good before. Man, what a worthwhile upgrade investment for the low cost that Parts-Express provides. Never going to shop anywhere else, again.David

Rated 4 out of 5 by from Great replacement speaker for little practice ampI bought this as a replacement for a blown speaker on a Peavey Rage 158 practice amp. It sounds decent enough for the price. Not great, but not that bad either.

Rated 4 out of 5 by from 4 of these replacing some Jensen MOD's!I own a lot of guitar amps.I play symphonic instrumentals, thrash metal, death metal..yes another annoying shredder but I also do a lot of synth stuff, jazz style stuff, alt. rock etc.The odd thing is, I prefer SS over tube for the edge and clarity tubes simply can not produce. I also don't care for the fizzy texture of tube clipping.I do however love the EQ response and ranging of tube amps and greatly needed a small combo.So a Behringer Vintager it was. Very tube-like EQ's and the distortion is incredibly close only without the fizzy texture.Killer amp from a brand with lots of top notch and garbage gear. After a year though, the nice Jensen MOD greenbacks in these start to sound awful. That midrange presence that just dominates every other bandwidth range in the tone stack(EQ).2 of these revitalized the dust collectors!Both nephews also have these and just like mine, they collect dust. This is a far superior speaker for THIS amp.So don't get me wrong, I love Jensen MOD's. I have a handful of them in other amps that they compliment incredibly well. Behringer preamp voicings just is not one of them. Granted I could just change EQ caps and resistors but this is another great option.Lord knows that the true culprit behind every great amp is 90% EQ voicing and pairing the proper speaker to that tonal palette.Originally these were installed in some small stage monitors that never got used and likely never would. Sound great but would only be suitable for a small stage or surrounding a drummer up close. These are plenty loud for a guitar amp but in a full range enclosure, I would only use them as a dedicated midrange speaker.

Rated 5 out of 5 by from Great midrange!I can see why people like this for small guitar amps. The midrange this thing puts out is amazing! I am using this driver as a midrange in a three way custom enclosure, and it works great! I would recommend this driver to anyone buildig their own professional audio speakers or replacing the drivers in their own speakers or amps. I do not believe that these can handle 200W, though. That number is probably the max that the speaker can handle. Figure on the RMS being around 80-100W.

Rated 5 out of 5 by from Studio Pro WH8 8" Woofer Accordian SurroundAn Excellent all around speaker with great range and sounding like a much more expensive speaker when used in a bass reflex cabinet. I bought one hoping to nearly match the other of a set of two where one had failed. It sounds so good to me that I may buy another now to match it perfectly.
