Rated 5 out of 5 by from Good tight sound , good value...Built a couple of two way bookshelf speakers(Dayton Audio TWC-0.25CH 0.25 cu. ft.) using these , morell tweeters and Eminence PXB2 crossover. Excellent performance driving a pair of Velleman k8040 monoblocks.Met my expectations 100%.

Rated 5 out of 5 by from Direct ReplacementCustomer brought in a pair of cabinets that had been damaged during a move. With no recone kits available and the manufacture no longer making that particular mod-el anymore these Daytons dropped right in and sounded great. No knock you down type of bass but tight and well balanced. Customer was delighted with the sound and best news was these speakers were 1/4 of the price of the originals.

Rated 4 out of 5 by from Sounds good.I built a center MTM speaker with two of these woof's and one Morel 298 tweet, crossed it @ about 2700HZwith a second Order (12db/octave) Two-Way Crossover, home made with GOOD parts from PE.... They sound good, they produce very clear and defined image. They are not a thump-er just a solid little woofer.. There cast frame is strong and all the parts just seem to feel and look very strong! I am still playing with the cross, but they already sound good! They aren't the killer woofer every one dreams about BUT they are worth the money they charge for them (so far)......

Rated 5 out of 5 by from Very nice wooferi bought two of these woofers to build two 2-way bookshelf speakers. i bought 2 very cheap tweeters (Nuance TW5-2LR 1/2") , i was planing on buying nicer ones once i had the money. i was impressed by the way they sounded, it has very nice midbass and does good on low frequencies if the volume isnt too loud. the distortion is very low, actualy it gets to its mechanical limit before it distorts! it doesnt handle too much power but its enough my amp is 50 rms and if you stay within the frequency response range it will definitley handle 40 watts with no distortion. i did have one problem with one of them but it was playing over its limits. the aluminum cone actualy cracked where it connects to the voice coil on one side and deatached from the voice coil, this happend at a paty and someone turned it up to the max while i wasnt looking suddenly i hear a crackling sound and later discoverd it was the cone viberating where it had cracked,. luckly i superglued it and it worked fine. ill upload a picture of where it cracked. overall its a very nice woofer for low power systems or a midbass in a powerful one if you cut off the lows. i would recomend!

Dayton Audio RS150-8 6" Reference Woofer

Is the 88/89 db sensitivity a half space rating? If not, what would the half space figure be?

Asked by: Fullrange2015
The sensitivity is derived from measurement of this driver in an infinite baffle. This creates a half-space environment on the low end, so baffle step behavior must be accounted for.

what tweeter could i mate with this woofer?

Asked by: dBAudio
There is no straight answer to this question. This woofer will work well with any tweeter that can cross as low as ~1,800 Hz, or that has an Fs around 700 Hz or lower. You may consider the reference tweeters as a good match.

Still not enough

Sorry to beat a dead horse, but 3rd order at 3k will be 20db down at 7k ELECTRICALLY--but the breakup itself is a solid 10db peak. The net response is therefore only 10db down about 1 octave from the crossover point; this is definitely still audible. Still wondering the best way to tame the peak (without the expense and part count of a very high slope crossover.)
Asked by: zing5
If you want to do this passively, you only have two choices. You can use a lower crossover frequency and trade off some of the high end response, or you can design a very high order crossover. There is no magic tricks to make it work, but there is always a compromise. Personally, with this driver, I would do a lower crossover freq. Say 1.5k at 4th order LR. Two coils and two caps isn't terrible and gives you more slope. You can always go 6th order, but in my experience, complicated crossovers like this tend to make more problems than they fix. Even 4th orders are more than I like to use if I can avoid itAlso, have you listened to the driver crossed over this way? The peak you are speaking of is inherent in this type of cone, but it isn't usually nearly as noticeable as the measurements make it seem. In fact some people tend to think of it as a fuller, richer sound as long as it isn't a blaring noise that only certain, very low quality, drivers tend to produce.

How to tame breakup in crossover range

My previous question still applies, because the breakup will still significantly affect overall response unless a very high order crossover is used. So again, anyone know how to tame that huge 6-12k peak (even though I'll be crossing it over about 3k)?
Asked by: zing5
If you use a third order crossover at 3K the breakup mode of this driver will be inaudible. It doesn't occur until around 7K or so at which point you will be down more than 20 dB and dropping.

Would you be able to provide C/R/L values for a notch filter to tame the 6k-12k peak of the aluminum driver?

Asked by: zing5
Since the freq response of this woofer is listed only to 4200 Hz, any peaks or even response above 4200 Hz will likely be due to cone breakup and other nasty resonances, as consequence of running it higher than its intended range. I would suggest a two-way design, handing off to the tweeter at 2.5kHz or so.. It would be interesting to see how high these drivers can go, maybe a x-over point of 3-3.5kHz even?
