Small sub: 2 6 1/2" drivers or 1 8"? Which one is better? (1 Viewer)

I made a small ported sub for my computer with the TB 6.5" Neo and a 70w amp and it exceeded my expectations. Two of the 6.5"s will move more air than the 8" so for an extra 20-30 dollars I'd take the 6.5"s.

Javier,

MCM also has an 8" high-excursion subwoofer. You might want to dig up a few datails on that sub, too. Last time I checked, it costs a bit less than the Tang Band 8" driver. Plus, the shipping might be less through MCM.

The long throw original released 8" MCM had problems. Not sure if they where/have been addressed or not. Cone sag from it's apparently poor/cheap designed suspension (even when used in a standard front face mount). Said to sound great for awhile and soon, very short time, it's no longer aligned properly in the gap and goes to crap.

This is not to say it has not been addressed if still available. I do not know, but read about the problem extensivly. Sorry can't locate the link showing the testing of both the TB-8 and MCM-8 at this time.

Given what you want, what you have amp wise, and what your looking for, I tend to agree the dual TB 6.5's in series might be the way to go. All those that have used the little TB W6 sub vented have been shocked at it's output. A pair would be rather impressive for a small sub and your power on tap would be in the ballpark.

You might want to read this little diddy using the TB-6.5-->W6-1139 "SC" version. (Not sure if it's a typo or it's the first gen TB W6 driver). A few of his TSP's listed also are different than what PE shows, he may have measured the driver (no mention of it) or again it maybe a first gen W6...


His rather cute 11" vented cube might give you an idea of what one it's capable of in the size cab he chose and the PE 70-watt plate amp he also used. Apparently built to match up well with some mini microbes he built. He had to make a trade off in port size which he explains, etc along with alot of other interesting stuff including graphs.

Geoff,

Thanks for the information on the 8" MCM driver. The driver is still present on the MCM site and listed as being available. But, from your information, it seems like it could be a bit risky to go through the whole installation and then have it suffer in performance. I guess after the initial issues were reported with the driver, nobody felt it was worth the risk to see if the issues were resolved.

Javier,

I also wonder if you couldn't find a capable car audio sub that would model well for in-home use? The subs you listed were all models that were from the U.S., which quickly jumped in price when you added shipping and customs details for your country. Certainly, you might be able to find something decent locally that would yield the performance you're looking for?
