Philips HQ customized with huge magnets, excellent for my idea of the build and available from a forum member. I am using a pair myself and requested more of them.

Each driver weighs 2kg and the magnet size is actually as big as the 8” cone in the front. Excellent highs, low end and magical midrange…

@premoddev is already playing them. Very nice built up in Betsy style. A further upgrade for better low end is possible.

Here is mine for an idea:


Amp is JLH, bias it at 5 wpc for lower demand on heatsinks and power supply which makes it pocket friendly too. Check the DIY audio forum for an updated low cost build.

We have perfect gentleman onboard @Hiten who could be of immense help on ideas how to execute it for minimal expenses. His builds are incredible vfm.

Yes I had this drivers in a Betsy baffle. But for OB, please make sure you have enough space to accommodate it. Otherwise won't get the desired results.

@yogibear yes, further upgrade is needed for better low end, but they all gone!! My brother took over the drivers :D

I have not built any good VFM or other speaker yet. for amps i could recommend chip amps or chinese class D amps. .

Speakers are different. All your diy efforts end in speakers performance. There are some cheap drivers on diyaudiocart. one will have to see drivers and search for any free diy build documented on web. some ND series tweeters are good vfm.
expectations should be kept low for cheap speakers. building box and buying drivers, designing crossovers is expensive. better to get wideband speakers of known parameters and build simple box. for box volumes and designing HFV members or diyaudio members will help. Least expensive I found are ready bookshelfs at doogesound.com. online prices are little more. No affiliation to the seller or anyone. listen and buy at your own risk. There are sound samples of doogesound on youtube. Yout tube is not recommended to judge SQ just to see they are working :p

regards.

Drivers I already shared. Class A JLH 1969 and similar TO3 package two transistor variants for full range drivers. (Tube amp will make the project expensive).

Your VFM execution of amps / preamps is quite popular….. chassis etc. Hence I quoted you.

Hi, I am just entering into this hobby. Can someone suggest a good active speaker for general music listening (Pop, soft rock, Bollywood music etc.) I have approx 220-250 sq ft area to fill but very limited space. I am planning to feed it through a raspberry pi streamer. Budget - max. 20-22K. Currently, I am looking at Sonodyne Alap & Bandish and even echo studio. Please help.

I have been using one from last 1.5 years and I am very happy with that
I am using Obage HT-303 and it's sound nice and neutral to my ears. I can't compare it to any high end device as I haven't used any. I have Onkyo HTIB and a Sony Midi system. Obage sounds way better than Sony midi system.

I've just ordered the HT-303 on amazon.

Another much ignored source for dirt cheap but good quality speaker drivers is the friendly neighbourhood car accessory shop. The young crowd these days keep changing/upgrading their ICE systems quite often and I have noticed that the older speakers are discarded or in most cases the accessory shop takes them giving a small discount on the bill. They often sell these off at low prices in the pre-used market. I have enquired and bought some speakers and stuff from these shops in the past. Some of these drivers (especially JBL, Pioneer, etc) are actually quite good and can be picked up for a few 100s. I have found the original 6 inch round frame twin cone full range drivers from Kenwood to be excellent and as good as Philips drivers in the same size bracket (standard fitting in Maruti Esteem, Baleno, etc from the early 2000s). Cabs for these can be easily procured from your friendly neighbourhood electronics street.

And then, there is the lowest cost option if you buy drivers from your friendly neighbourhood electronics street and have them mounted in cabs that can be procured from the same place. These days these low cost drivers are of better quality when compared to the old times and brands like bolton are back.

Here is an example of a 5 inch driver which i bought about a year ago for a TV repair project. Cost me about 150 bucks I think.

True. I built a 5.1 out of micca OoO’s from Amazon. Paired with a marantz 5.2 AVR and Polk sub. Discreet and does the job

I remember Bolton from my college days. I built a cassette player amplifier from scratch and Bolton was the top end choice for me for speaker 😁. I couldn't afford it back then and went with Sweton to save ₹50 or so for a pair of 8" drivers.
