6.5" speaker for bass?

#41
Close enough. These drivers won't stick into the box very far. The ports are also small and their length can be varied. The thing doesn't make wild response changes with small differences so if it ends up being .7, or .72, I really doubt you'd be able to hear much if any difference. The most obvious tone changes would come from trying shorter and longer pipes = higher and lower tunings. It's a quick model figuring people could pin down the tuning on their own by ear according to their tastes.

It just so happened the toilet paper roll is a good middle ground to start from, made a curve my ear would most likely be alright with, and is enough to prevent chuffing with the lower power these things will be getting.

If somebody wants to try other alignments, bigger cabs, etc., it'd be cool to see some other ideas.

I'm coming at it from the angle of very low power, very easy, decent, and cheap, with it playing living rooms or porches.

That one, with two $9 drivers, small panels you could probably find for free, small bottle of glue, tiny package of brad nails or something, a couple empty paper towel rolls, 2ft. of wire and a 1/4" jack....it's probably about a $30 build, + choice of grill and covering. Oh, and probably shipping on the drivers.

One thing I'm uncertain of is how the softer suspension of the hifi driver is going to take to the dynamics of the live instrument. They will flop around more easily than a MI driver, but I'm not sure by how much.

That's why I'm just thinking 15 watt practice amps even though the model says it'll handle all of 45. Not sure how much it would hold you back trying to scale it up to some 6x or 8x you could actually gig with. There's a reason you use stiffer/sturdier drivers for that.

In the livingroom situation, just having something running 90some db or slightly better with a decent bottom that sounds like a bass should make it so you don't have to push it very much.

I run my bass into a Vox Pathfinder 15 (I know, try not to bash me for using a guitar amp, I just LOOOVE the tone) And usually run the internal speaker (it has no ext. speaker jack, so I have to rig the speaker wires to an output jack to run it into a cab) but, every 2-3 months the speaker in it farts out/the voice coil overheats (I believe thats the term, I'm not great with speakers), so it becomes unusable :(. So, I was wondering if there are any 6.5" speaker for bass? I don't mean a 6.5" running the mids/high, I mean the 6.5" will be running the entire bass. I'd like to keep this cheap (I know the speakers I put in it were dirt cheap) and have okay tones. Any thoughts?

Phil Jones :D

Phil Jones has a cheap 6 1/2" speaker the OP could use in his VOX? Really?? Could you supply a link, we all might be interested in it.

I have been looking at the Dayton PA165 speakers - was thinking about building a 4 x 6 " cabinet. I cannot find the dimension sheet I had laid out at the moment, but my cab was very similar to yours, except it was going to be deeper and was to include a couple of port tubes. Project was put on the back burner, but I still intend to build it.

I suggest that you check with Parts Express on the x-max of that speaker before you start spending money. According to the spec sheet, the x-max is 0 mm, which may be a misprint, or maybe the length of the voice coil is the same as the height of the magnetic gap (which is good for efficiency and feasible for a guitar or midrange speaker, but not good for a bass guitar speaker from a fartout standpoint).

The spec sheet says "ideal for midrange applications", which doesn't bode well for use as a fullrange bass guitar speaker.

From parts express web page:
Aura NS6-255-8A 6" Paper Cone Neodymium Magnet Woofer
The Aura NS6-255-8A is a compact, lightweight bass driver for music playback and home theater systems. Aura's NRT motor design arranges eight precisely arced neodymium magnets in a circle surrounding the vented pole piece, creating an exceptionally deep and strong magnetic gap. The deeply set, underhung voice coil keeps more wire in the gap during operation than conventional designs, delivering astonishing low-distortion bass capability far in excess of what the driver's nominal Xmax rating would suggest. Buyout, limited quantities.

Specifications: *Power handling: 50 watts RMS/100 watts max *VCdia: 1" *Impedance: 8 ohms *Re: 6.0 ohms *Frequency response: 55-5,500 Hz *Fs: 55 Hz *SPL: 91 dB 1W/1m *Vas: 0.58 cu. ft. *Qms: 10.8 *Qes: 0.58 *Qts: 0.55 *Xmax: 3.9 mm *Dimensions: Outside diameter: 6-1/8", Cutout diameter: 5-3/8", Depth: 3-3/8".

Sorry I wasn't clear, B-string; I should have specified which driver I was referring to. The Aura woofer you linked to has plenty of exursion for this application, is a steal at nine bucks, and overall looks quite promising (within its reasonable limitations), as does will33's proposed cab design with its high-tech port tubes.

No problem Duke, glad to be on the same page :)
