now only yellow coloured cone is coming I don't think that has any relation to old boltons except the name
Please can you share contact number of the person, I'm from Mumbai.
I have a Jamo D 6Sub, when I press the cone the bass is okay when I leave it humming sound along with muddy bass
If you get down on Grant Road railway station East and walk under the flyover (Frere bridge) and go straight towards the main-road (LR) there are few Speaker repairers there on the right since years.
I too am looking for personal reviews about some good fullrange speakers (smaller than 7") available online or in Bangalore.
Anyone who says that 12" speakers are full range has to basically do lots of homework.
Also has anyone tried the Dayton DML drivers?? I was on the verge of purchasing some but gave up the idea as I have too many things on hand.

"Anyone who says that 12" speakers are full range has to basically do lots of homework." Why ?
I dont want to go into the technicalities as its your homework, btw have you ever seen any 12" full range drivers?

No, that's why I asked why. I hope you are kind enough to take the time to explain.
Same material and geometry behave different at each frequency spectrum (causing cone breakup at higher frequencies).
Also, the cone dimension dictates the "beam" directionality at high frequencies (the cone starts acting like a parabolic reflector at lower wavelengths compared to its own dimensions).
Both these facts have been highly utilized by electric guitar players who value 12" speakers for producing and recording characteristic overdriven/distorted tones that have significant energy in the 2000-5000 Hz frequency range.
Very good examples seen in the PA speakers. Most of them utilize 10-15" woofers and are utterly lacking in the critical 1600-3200 Hz spectrum because one is forced to crossover them out.

No frequency response is published so no comments other than that manufacturers can easily publish fake figures - are you going to take them to court? Mostly people rely on forums and circles to get real life feedback about such things.One Pair | Reference Level 15″ Fullrange Drivers | Platinum-15 - Lii Song (丽颂), unique speaker, amplfier, quality and cost-saving parts for HiFi DIY

Typically, full range drivers used are smaller diaphragm <5" that can do linear justice to 100-8000 Hz spectrum. The lower frequencies can be boosted using box/tube resonance.
Yes, the published figures appear closer to real life here. IF you observer keenly, there is a sudden rise around 1200 Hz and then onwards the linear-ness is a disaster. The dip at 5500 Hz means it becomes practically useless above this frequency. This is good enough though for guitar amp modeler (check out the stated purpose) because it has emphasis exactly where needed 2000-5000 Hz.or ems LB12EX

There really is NO full Range driver in the world which has linear response from 20Hz to 20KHz. Period. Linear means +/- 6 dB (really lenient here I am).
We can call them as Wide bander at the most. Commercially, marketing mantra can name anything with something else.
In that perspective, with my own user experience over last 12 years, I like Ahuja SK-12FRX and DX12-F200 drivers as wide banders. booming is fine with me as I don't move while critically listening a song reproduction, enjoy it sitting. and I measure a reproduction with my ears only.

Ahuja is excellent driver. paper cone lends to very natural human voice (serves intended purpose of PA systems)

I am using a speaker made with the Mark Audio MAOP 11 , readily available here , with excellent results.
It is a full range hence the speaker is single driver.

Hi, do you have any contact of them or know of their website to see their specification and order?

+1 the MAOP's are very good but they are not cheap. Still, if one is committed to such a config, they're worth considering.
After using various drivers past 15 years in my DIY project, I am now very comfortable assembling my own drivers for my project. This gives me flexibility on MMS and CMS and choice of surround and spider. My current OB subwoofers drivers sre fully assembled by me. Also the full range surround are DIY with goat skin surround. This allowed me too arrive at a tone that's accurate and natural resembling live unamplified music which I prefer over studio type tonality.
