Default Need advice on an 18" driver

Guys, I got my hands on a nice pair of 225 liter (8 ft3) speaker boxes with a cut out for 18" speaker, braces and all. There are also 2x4" vents in each box. I need your advice as to what inexpensive 18" driver would work reasonably well in these boxes. These subs are for a small club in LA area where they still play classical music every Wednesday night.

Define "inexpensive"...

The box volume seems right for the B&C 18TBX100, which goes for about $290 a pop, and you'll get into the low 30's if the box is tuned right.

How long are those 4" vents?

$290! Ouch! I was trying to help the club and undertook to build a system for them. I'm already out of $300 for the top end (511 Altec horns with 802 compression drivers), about the same for 100-500Hz midrange. I was hoping to complete the entire project for under a grand. Me thinks that the length of the vents can be easily adjusted.

For an 18" sub, the Stereo Integrity HT 18 is hard to beat at its price point.

Eminence sigma pro is quite cheap for an 18 inch sub.

Default ~200 Liters reflex at a reasonable price for PA

Let's see it (and cheap!)..
THE BEST (FOR TUNING/ALIGNMENT/PORTS AND ENCLOSURE).
Eminence Omega Pro-18A 18" Cast Frame Woofer Driver
Then very nice.
Eminence Delta Pro-18A 18" Driver 8 Ohm
and following capable drivers.
Eminence Sigma Pro-18A-2 18" Cast Frame Driver
Dayton Audio PA460-8 18" Pro Woofer
The last ones being good in smaller speakers (170L) and the first ones in larger ones (250L).
We will tune it 4u after you are settled.

Hi Egindin,

Like Inductor already mentioned, a pair of Dayton Audio PA460-8 would cost you $199,70 and simulate very well in your enclosures. Your vents need to have a length of approx 2.75 inches (depending on the exact volume, without ports and driver).

Cheers,
Djim
