3" or 3.5" full-range driver that works with infinite-baffle ?

I know this is an odd request. So, I'm putting it in the Full-range section where oddball speakers are the name of the game.

I'm replacing the incredibly cheap factory 3.5" speakers that came preinstalled in the top of my enclosed shower unit.
The back of the speaker is infinite baffle, using my entire bathroom as its enclosure.

While the front of the speaker fires into a medium-closet sized shower enclosure.

I know I won't get any bass. But can you think of any drivers that would excel more than something designed for a tiny speaker box and would work from I guess, 120hz-12Khz (or better)?

I'll need something that isn't un-treated paper.
Because it won't get wet but there will be lots of moisture in the air.

Per my digital calipers, the cutout diameter is a tad over 3.3".

My amp is an 8 ohm eight channel Pyle amp (using for whole-house audio).
It's not clean anywhere close to max power but I think it'll deliver far more power than I need in a shower enclosure.

By Closed Cell Foam, are you talking about those cheap $5 foam enclosures you used to be able to buy on Crutchfield?
Those were **** for pro installers but I guess something like this might work.
I'll research!
 
Now to find some bass blockers for everything under 60hz (or about that range).
Should be easy enough to find something. I know I'll find 80hz.
But 40hz is too low and I'd like to find something a bit below 80hz because the 80hz bass blockers remove too much bass IMO with their rolloff.

Since these will be used close and at not too high a level, you should be able to boost the lower frequencies without too much trouble.. especially if you have a little excursion capability. To get this you may look at some which are a little less sensitive, but that may be the sensible trade-off in this situation.

I can't figure out how to edit my threads anymore though.
You should have an edit button at the bottom of your first post. If you don't, let me know and I will look into it for you.

+1 I began using Infinity in my vehicles back when the Kappa series was introduced and to my ears you can spend more, but short of some horn systems I did there wasn't any that were more HIFI that I auditioned. Also have used them for bookshelf speakers for others.
Thanks!
I used Kappa separates f&r for my first "serious" car audio build back when I was in my 20's.
Haven't had anything that nice since. Haven't had a nice system since then (in my vehicles).
I'm happy that Kappa is still a brand that people are recommending!
I visited their factory on Balboa back in the old days and was really impressed with the atmosphere there.

I didn't at the time. But this was right after the forum software said I had to wait for approval for my thread to be posted.
It finally posted my thread but would not let me edit it right away.
So, maybe I was still in software flux. Being too anxious.
I do see the "edit" button now. Thanks!

I'm a fan of high sensitivity speakers but didn't consider the pluses in a tiny speaker. I've only ever thought about it with large, rock speakers and subs.
Since I'm not Needing loud with these, I think medium or even low sensitivity in the low 80's (or lower) will be fine. Maybe!?
 
Yes, thankfully when Harman bought them they didn't 'mess with success'.
One of these days I'm going to research how JBL/Harmon/Infinity all came together.
I'm sure there is a huge and amazing thread about it over on AudioKarma.org.
I probably even read it but I don't remember the storyline.

As popular as audio/video is these days, a movie could probably be made of it and it would be successful in the box office.
If Facebook and others can have a movie about geeks... then just imagine what kind of cool movie could come out of the audio/video nerds from JBL, Infinity, Harmon Kardon, etc.
A 1's and 0's geek could not come close to the party level of an a/v nerd.

I remember Harmon (or H/K?) had a refurbished outlet near Thousand Oaks or Oxnard, CA.
I think it was more towards the Camarillo outlet?
It was hit or miss as to the quality you got from their stuff out of that store.
It was during a time when H/K was out of my budget (college student). So, I rarely went to the store.
 
I like high sensitivity too. In your case I think the lower overall power requirements will make everything less critical.

In any case, I'm familiar with some low excursion (1mm xmax) drivers where I've used them running to several mm excursion without noticing any problems.

So, maybe I was still in software flux. Being too anxious.

You're welcome. Yes the new software shuts you down to newbie status after a period of inactivity.. essentially to protect you and the site, and part of that means taking away the first post edit privilege.

I think I'm actually going to go with an enclosure after all.
I built a foam-board enclosure for a mini-Karlsonator a couple years ago that was super fast, easy to build.
And has worked out just fine out in my garage.

So, I think I'll cut out some 6"x6" panels and hot glue them together to build an enclosure without a baffle/face.
Then, I'll hot glue it to the top of the fiberglass shower enclosure, around the speakers.

It won't be visible unless anyone gets up on a chair and looks at the top of the shower enclosure.
So, quick & ugly will be just fine! Especially for such a tiny speaker that won't be asked to produce high volumes.

I'm not sure whether or not this might actually be beneficial to the sound. You said it was an infinite baffle, if it's really infinite or very big there's no need for an enclosure as the back wave is already separated from the front wave.

Wasn't aware there was a story beyond 'money talks, BS walks!' 😉

Had several memorable H-K tube gear, but in a roundabout way it was at once stolen, yet paid $1 k cash + pristine Altec 9444A/SA studio reference amp, though pretty sure once repaired he ultimately got the better 'trade'.
 
I have a couple pair in use, one set is in some bookshelf speakers that I made for my daughter, powered by a dual tpa3116 board.

The boxes are sealed, sized after some JBL outdoor speakers that looked as if the had the same drivers perhaps. I was thinking that they may need a small breather type of port (aperiodic), however, they didn’t seem to respond any different in a sealed box vs open back cabinet with a couple inches of open cell foam fitted snug behind the drivers.

When I used another similar pair (4”, without the tweeters) in a compact truck dash recently, I just baling wired pieces of the foam over the backs of the drivers, with a relief for the back of the speakers, so that they completely covered the backs, and those also sound good down to around 60hz, as already noted by CZ Eddie. Small space, so gets loud enough for me before breaking up.

After extensive reading a few years ago, I decided that Infinity/Jbl speakers were going to be the cut off point for me in terms of diminishing returns…
