Default Bang for the buck 18"/15" subs?

Looking for some better drivers for my BR boxes. Kappalites are on sale for $200 and this 18" is under $100, what other bargains are out there?

Greetings,
In my opinion based on 39 years experience, this woofer model from PE is about the best bang-for-the buck performer:

Dayton Audio ST385-8 15" Series II Woofer 295-130

One driver per channel adaquate for medium sized rooms, but 2 per channel
in a reaction-canceling enclosure would be almost world class.

The 3015LF is my first choice but I am exploring cheaper options.
This will be used for live sound and DJ work so I only need to cover 40-100hz.

I can build another box but already have a 200 liter box and a 175 box with $25 bargain basement 15"s loaded in them (not really subwoofers).

Sensitivity: 98dB (W/M)
Impedance: 8ohm
Re: 7.2ohm
Le: 1.37mH
Frequency response:
32Hz~2KHz
Fs: 32Hz
Qts: 0.41
Qes: 0.475
Qms: 2.9
Vas: 232 liters
Xmax: 3.75mm

About anything will be an improvement.

Ordered the Kappalite before another round of neo price increases. (I should have bought four back when they were $160)
Not sure what type of problems I will create if I run my pair of low budget boxes @250watts each and the 3015fl @500watts but I will have fun finding out.

Found some 15" MCM specials for $37 each.
http://www.mcmelectronics.com/conten...ts/55-2963.pdf
The Datasheet says...

Sensitivity: 97dB (W/M)
Impedance: 8ohm
Re: 7.2ohm
Le: 1.619mH
Frequency response: 32Hz~3KHz
Fs: 32Hz
Qts: 0.39
Qes: 0.437
Qms: 3.3
Vas: 286 liters
Xmax: 7.5mm (3.75 in description)?

Could be a bargain if it has a true 7.5mm of travel.

"Could be a bargain if it has a true 7.5mm of travel. "

Divide that by two, it's a misprint. The catalog description says:

* Sensitivity: 97dB (W/M)
* Impedance: 8ohm
* Re: 7.2ohm
* Le: 1.619mH
* Frequency response: 32Hz~3KHz
* Fs: 32Hz
* Qts: 0.39
* Qes: 0.437
* Qms: 3.3
* Vas: 286 liters
* Xmax: 3.75mm
* Overall frame diameter: 15.28"
* Required cutout: 13.94"
* Mounting depth: 6.30"

Default Oh Yea 7.5mm of travel on that driver!

Just got a E-mail from MCM, the datasheet from the manufacturer is correct and website is being updated.

Isn't anyone going to ask what is the volume of Mr Doom's cabinets and what the port is tuned to? And are you willing to re-tune the port if necessary?

The woofer's potential is irrelevant. All that matters is how it will perform in your cabinets with your crossover. The folks at Madisound and Parts Express and probably other vendors will be able to help you select a woofer that best suits your needs. You would be lucky if the best woofer for your cabinets was also on sale.

Good luck.
