Dayton Audio CE Series CE65W-8 2-1/2" Auxiliary Bookshelf Shielded Extended Range Driver 8 Ohms,Black

Bought this to replace the subpar Yaesu SP10 speaker. Sounds a million times better. Seller should tape box shut so speaker stays in box during shipping. Thankfully just minor bend on mounting hole. Pilar’s easily fixed

FT-991Aの海外ファンサイトでAmazonで購入したスピーカーと取り替えているのを見て即、Amazonで購入して取り替えました。 SP-10のスピーカーは昔のトランジスタラジオのスピーカーのような薄いもので音的には本体と比べて良いとは言い難いものでした。 半信半疑で取り替えたところ、低音が出て音声が締まり、了解度が上がり聞きやすくなり長時間でもストレスなく聞けそうです。 これでデザインだけの外部スピーカーから本体より良い音質という機能も備えたSP-10になり大満足です。

I ordered one of these (make that two since I have another TL to build) to finish up a some transmission line enclosures that I've printed off. Especially for how cheap these are compared to the more bougie options that are available, they do a shockingly decent job as a mid-bass driver given the tiny size. There's really not that much surface area available to generate all that much pressure for any form of gut-punching bass, but give these little guys a tuned port cabinet or a transmission line, then be strategic with your room placement and it's more than possible to have one of these rattle your noggin just the absolute tiniest little bit if you drive them hard enough. In the transmission line enclosures I'm using, these drivers can just about squeeze an audible 40Hz, but they become extremely noticeable once you pass the 100Hz region... That's where these drivers (enclosure permitting) can just about tap you in the chest and occasionally rattle the ol' nut when set loud enough. I'd generally advise though, as Dayton advertises, using these more as am all-round mid-bass to treble range driver given they don't really have a whole lot of excursion (movement of the cone) to make up for the lack of driver size. Again - you *can* achieve the tiniest amount of sub-bass with these drivers like I have managed to with a tuned enclosure and placing the completed speaker where the bass resonates, such as an enclosed shelf or under a desk... But it's really not worth trying to push every single decibel you can from a driver running outside the sensitivity range it's optimised for. You're just asking to release the magic smoke doing that!! The drivers themselves aside... I also really love the fact Dayton provides the characteristics for all of their drivers on their website. It makes obtaining the numbers you need to plug into the calculations for cabinet, porting or transmission line length much easier to find... Definitely beats renting a hard-to-find testing setup complete with anechoic chamber and measuring the characteristics manually!!

Mit einem Hochpasskondensator (220uF-330uF) kann man dieses winzige Chassis in einem geschlossenen! Gehäuse (2,3Liter) trotzdem hervorragend verwenden. Optimal linear bis 3kHz geht es auch mit kleinen Abstrichen als Fullrange durch. Schmalbandige Senke bei 8kHz (7dB). Sperrkreis: 0.68mH - 10uF - 12 Ohm ist zwingend erforderlich. (w.g. Bafflestep) 90Hz-16kHz +-2dB sind aber für ein 7€ Chassis herausragend.
