DRRI speaker (spkr W/ db general Qs).

[Sea Chief]

That would be Fluxtone. Their web page is at www.flutonespeakers.com

Very interesting ( FluxTone Guitar Speakers ). I bet they cost a bundle though.

The one I looked at on the website was U$1800 list. About the same as a baker's dozen of Vintage 30s

So hang about.. I need to make my ring looser-?
I think Im going to make a muffle box thingy, and just stick it on my head.

Let's not be too hasty! It was just an idea!

There are also the Eminence FDM (flux density modulation) speakers, Maverick and Reignmaker. In the $125 range, they are adjustable from full 100db down to 91.5db.

Hmm... The price is reasonable but think that you would need much more than an 8.5dB adjustment range to be very useful.

I have a sub-1W amp that, through a 2x12 cabinet, makes for a nice bluesy drive that doesn't bother the wife watching TV in the next room. To get that volume from a 40W amp, we'd need to dial the speakers down by 15-18dB by my calculation. How about a 10dB - 12dB attentuator and then a FDM speaker?

[thinking out loud] Has anyone here had experience with 'yellowjackets'? They don't promise to make your amp living-room-friendly, but might be part of a solution. I'm curious to hear any comments about the product. [/thinking out loud]

My FluxTone Model 10 at max attenuation (supposedly -33dB) allows my Vox AC30 to be cranked at domestic friendly sound levels.
Yes they're horrendously expensive but it seems to be the only way that facilitates me being anywhere near a cranked stage amp without hearing protection, and so be able to hear what they actually sound like, and to be able to do so without driving the neighbours nuts.

Aha so the reason theyre so costly is they have big attenuation compared to the FDM eminence: I suspect the em's are more a gimick/ marketing ploy rather than a serious attenuation idea.. but as theyre not firecely costly thats fine with me and possibly an idea too if as eschertron alludes to, used -with- a decent 'proper' attenuator unit (& in my case with my DR if I add a 12ax7 in V6 (PI) too to get some grind at earliest opportunity too).. I might have tamed the DR completely for use at home having spent a fraction of the cost of a fluxtone speaker: that would be very sweet indeed!

I tried the 12ax7 in v6 with my DR, with the P12Q test in fact, and altho terribly bright/ like a tweeter as s'one said (made me think the amp had gone wrong) I was very surprised as the distortion was there at room levels (more cause to think the amp had defo gone wrong). No attenuator. As it sounded poor tho with the p12Q on a glass table next-to, firing up, I discounted the whole test sure the amp needed addressing. maybe if Id tested the p12Q mounted.. then I might have got both nice break-up without blowing the next room's ears at all, and a nice crisp speaker with seemingly a nice low-efficiency.

I must try the P12Q again- not mine tho, so alas I cant just 'pop round & try it'.

'I was very surprised as the distortion was there at room levels'

That may have been due to all the lows and mids were cancelling themselves out, so the sound pressure couldn't get anywhere near its normal level.
A 12AX7 in V6 makes no difference to the amp's power output.
Best to erase any impressions you gathered from that test!

For me, FluxTone's key benefit is that the tonal balance seems to stay consistent right down to the max attenuation.
Whereas it may be expected for the tone to get brighter as the magnet strength is increased, as noted in the Eminence blurb for their variable permanent magnet system.
And the tone from the Model 10 is great, at least as good as anything else I've got or tried.

No i dont suppose it will make a difference to the amps power output, but the reason I put a 12ax7 as PI is some players prefer a 12AX7/A in this postion as it allows an amp to "break up" or distort at lower volumes.

[pdf64]

I suspect that may be internet 'received wisdom' (ie gets repeated so often that no one questions it) which is actually nonsense!
The only meaning that has a jot of reality is that the higher gain of the 12AX7 results in the power amp overdriving at a fractionally lower setting of the volume / tone controls; the actual sound pressure level of that power amp overdrive is unlikely to be affected whichever tube type is in use.
A 12AX7 has a gain of about 30 in the V6 LTP, 12AT7 about 20; that's 3.5 dB, but it's inside a global feedback loop, so even that minor difference will be reduced.
To me, 12AX7 tend to sound a bit nicer than 12AT7, especially when overdriven, but being inside a global feedback loop may tend to the slightly higher gain of the 12AX7 resulting in an overall more abrupt transition into overdrive.

Ok this was my point tbh. I have 2 sources of info then. Here MES, and I respect and use it of course.. and other researched viably decent sources too. One says one thing and says the others is "nonsense".

Here for eg is the exact wording I used (purposefully cut & pasted to make it seem I have gleaned some info from an unrelaible source/ prob got a bit wrong along the way/ and regurgitated to suit, or in my way, on a forum): If you go down to V6 info:

http://www.kcanostubes.com/content/f...ecommendations

The woes of too much info! It a bit like my mate Dave who says he has so much p*rn available, he doesnt know quite where to start "for my 'fapping'" he says (whatever the heck that is).. and once hes chosen "..& then its gone Mr. Softie" (still no idea).

"for V6. Some players prefer a 12AX7/A in this postion as it allows an amp to "break up" or distort at lower volumes due to being "mis biased" in the 12AT7 circuit."

If it really is badly "mis biased" with a 12AX7 as it states in the quote above then the PI will be clipping before the power amp and the output power will be reduced (like a post PIMV) but if it's not "mis biased" enough it will be as pdf64 said - same output power but at lower vol pot setting, so I guess they could both be right

Maybe there's a new market for 12" guitar speakers that have tiny magnets(low efficiency) for the low watt combos that are all the rage. Most tiny magnet speakers that were made have equally tiny voice coils and really aren't up to the job. Id make one, but I prefer louder speakers myself.

I have a feeling (never a good start I admit) that too small a magnet= too small a voicecoil= not enough heat dissipation= heavy bummer/ spkr might fry.

Anyway appreciate the replies, I think Im done on this subject/ got my self sorted.. so thread fizzling out, thx alot. SC
