Extended/Full Range vs Tweeter

[GammaRadiation 10+ year member]

What's the real power sensitivity like on these things? I've been looking through PE and a few other sites and they all seem to be in the 80-85 dB*w/m area with 20-30w RMS power handling. I dont like ear bleeding highs, but I'd like to be able to get in the 110-120dB area for windows down jamming and more is always nice when you want it...or want to use your vehicle as an oversized boom box.

if you want to achieve 110dBA + then you don't want these small, full range drivers as a tweeter substitute. the added challenge of getting them on-axis makes them even more work. and they really don't sound good when pushed - maybe if I was using underhung drivers that wouldn't be the case.

95dBA is easily acheivable and still a very good listening volume.

Morel has some higher power handling drivers - reflected in the cost. apparently, high power + small size = $$$

when i get a break from work (been working late nights) i want to combine the 2" full range in teh dash corner with tweeters in my apillars. I would run the dash down to 300Hz or so and increase my door midbass crossover point to meet it. i'll do this anyway since i am going to rebuild my kicks. when i build my kicks i will have a removable baffle sized for drivers as large as 7". the purpose for that is to give me someplace to put my midbass while I build fiberglass door pods.

i'll do RTA testing for each step and share with the group. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I still have RTA testing to do on the variations I pictured above.

Cool. I really want to try out a 4 way system with ribbon tweeters, mids, midbass, subs but I just dont have the money right now.

i would like to try ribbon tweeters someday. i have tried ring radiator and recently bought another pair to put in spheres.

found pics of the tang band on-axis mockup. the final version will need to be much smaller than this and fiberglassed - i lost too much visibility. i'd glass the entire airspace and not leave the back open.

and some of the drivers i'll be playing with (two tweeters are for a refurb project)

so you had the mids on axis to the driver across the cabin? passenger side speaker to driver seat and vice versa?

how were the results? I'm looking to do pillars in my car and I have the 4" tang band bamboos and am looking for some ideas to try for aiming.

I haven't built a fully sealed mockup yet, so my tests were only partially useful. It is a promising concept. But I want the inside edge to be well rounded and much shorter. Also, glass is a terrible inside wall. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
