Hi efficiency woofer

[jimbones]

Need recommendations for a driver:
Size: 7-9 inch woofer
Budget: $275 ea
Efficiency: Min 91db
Prefer sealed box
Will be used in range of F3 to 300hz
Does not need to go too low say F3 @ 50hz

I may be dreaming but I haven't found anything that fits the bill yet.
Thanks.

Not sure of any other than the JA-8008 HMQ. I have a friend who has a pair and might be willing to sell them but that means customs + postage to inflate the price (considerably).

Hi, i don't where you've been looking, or for how long ? but there must hundreds that would meet your requirements, & for a Lot less $ too

Just one example of one www to check out US SPEAKER PARTS - Speakers, Speaker Cabinets, Guitar speakers, Bass speakers, , Woofers, HF Drivers, speaker upgrades and replacement speakers. Eminence Speaker, JBL speakers, 18 Sound, B&C, EV, Tannoy, Peavey, Celestion, RCF, Jensen, Beyma, Fane, P

These used to be $220... https://www.madisoundspeakerstore.c...s-excel-w22ny-001-e0045-8-nextel-cone-woofer/

For under $200 you can purchase a PAIR of SB23NRXS45-8 woofers with combined over 91db/watt and mount them in a counter-force, push-pull arrangement to remove vibration. Sealed 2.5cuft box will reach 50Hz without equalization. With L3=0.6mH, these are musical woofers with very good sounding high frequency extention.

I should mention this would be used in a hi end system with very revealing electronics. I did find several choices at US Speaker but not sure if those compare SQ wise with JA and SB etc. BTW I could go up as much as a 10 inch driver.

You'd have to specify 91 dB/1W/1m or 91 dB/2,83V/1m?
Half space or open space? That dB spec one gets with TS
paremeters is a half space value. When you put it in a box
and equalize baffle step, you get a lower value.

I am currently using a dayton RS270 and i want something at least 3db more efficient. It's cheaper than doubling my amp size

 

[cumbb]

Which dimension the room has?
DY-1256U. Push-pull-arrangement, as mentioned. To regard any parameters would not be necessary.
The bigger the room the more drivers. Because very cheap and/but very very good.-)

20x15. I have a Velodyne HGS 12 subwoofer for the very low end.

 

[Lojzek]

Jim,

Have you considered PA drivers?

 

[cumbb]

300 m^2? Uiuiui.
The HGS is a roaring box. These deeps are really very low end. In my mind. For real "sub" you do need much more diameter, rigider casings, cleaner amps. In my mind.

 

[jimbones]

Jim,

Have you considered PA drivers?

Will I get the SQ needed? Although I don't want to limit myself I want to make sure I am using a driver that does not compromise SQ.

 

[Lojzek]

Depends on what the designer does with all these bits.

How many Watts do you need from your amps?

I have a 130 watt amp (Modwright LS100SE)

That would be huge but I think the OP is american so it may refer to feet which would make the room a much more reasonable 27.8m^2.

AE TD10M, $ 309

Acoustic Elegance TD10M high efficiency bass/midbass driver

You will have to search hard to find better.

Sooooo nice I guess that the price of quality. Now i have to do some calculations. I have a 1.5 cu ft box here.

AE TD10M-8 is a very nice driver for a two way speaker in a ported
cabinet to get an F3=60 Hz. It would be a lot of money spent just to
play the 50-300Hz region and in order to properly make a XO point
to a sub, you'd want that kick bass placed in a sealed box with the
right Qtc. Did you have DSP filters in mind?

Yes in a fleeting moment I admit I was dreaming I had $800 to spend on 2 woofers. That won't happen.
