yes, along with pdi/invisiglass because they are mods that are not only great but also reversible at any time with no effort.

hell yes. cheaper than ff or pp kits, and can hook two up. wont rattle pin either.

We have plug n play sub out adapters for those who don't want to hand wire to the speakers. Connects directly to the stock audio board. $35 shipped includes wiring and free shipping in the USA

After getting a few external subs, I can't imagine not using one anymore.

To really hear the difference it makes, try playing a game with the sub turned off.

At $70 that's only $35 per pin!

I think so and not necessarily or always a separate powered sub in a cabinet on the floor underneath.
a woofer replaced with a much more efficient one can do wonders, people tend to look at a speaker's max power capacity then wonder why their new 400w 6x9's whisper when fed 5-10w.. oops!
if an in cab stock woofer is efficiency rated 86-88 Db from 1w at 1m (usually unmentioned specs), replacing it with one that'll do 93-94 Db on the same 1w/1m will be a LOT more bass output.
I'm an amateur audio nut, IMHO best bang for the buck is MCM paper cone cloth surround woofers, not expensive.. find at amazon or MCMelectronics.com site. they may not reach into the deepest low frequencies but look at the "X-Db 1w/1m" efficiency and the prices for the 8's 10's 12's, its pretty hard to beat. something like that will do a whole lot more with a machines stock audio amp.

another option is Goldwood (PartsExpress.com) dual voicecoil woofer. if the existing woofer is 4 ohm just parallel wire both 8 ohm voicecoils (back to 4ohm) usually outperforms a single voicecoil woofer, again look at the efficiency specs how many Db from 1 watt at 1 meter, very helpful for deciding.

stock speakers in the backbox can sound great and huge if theres some ballsy bass backing them up, same for 2.1 computer stereo speakers, home theater setups etc. take away the sub they sound like the little tin cans they usually are.

many people dont like connecting a separate sub, cleaning around it or moving a machine becomes a bit more of a hassle. not saying subs arent nice or nicer (and a good bit more expensive sure), just pointing to the other option for getting more bass out of typical small power audio amps. if it makes the glass rattle theres always foam tape (or turning it down? naaaw!). if theres room to drop in a 10 or a 12, I'm sure tempted (step away from that jigsaw boah!).

A complete speaker upgrade is even better. Really smooths out the tinny sound.

Agreed, and pinball pro systems (not system 11) come with an external subwoofer output, for people that want it all. We added this about 4 years ago.

I've done this with just about every game I've owned. Usually I do a full kit upgrade.

It's probably my #2 mod.......LED's then speakers.

My opinion is the best bang for the buck is to put fresh clean new glass in every game.

$25.00 a sheet and keep it clean = makes any game look better.

The newer sterns benefit most from a powered sub

Agreed. Awesome upgrade for pretty cheap. I love the Polk PSW10 as well....

WOW, $25, cheapest around here is $40.

I added a sub to F14. Bought a nice 100W Optimus for $10 at a flea market. That games explosions, etc... really sound good with it, but honestly one game with one sub is enough- there's too much competition when the games are on.

I would consider it more of an add on than a mod. I'll be adding this to my gameroom when I finaly get Ironman. (that's if I don't get laid off within the next two weeks)

I can get them at the local (to me) shows, Allentown Pinfest and White Rose Gameroom Show for 25 bucks all day.

I have also ordered pinball glass (21" x 43" x 3/16" std. tempered, "no bug") from local glass shops for 25.00/sheet when we order 10 or more sheets at a time (group order)

Your local prices may vary.

I just picked a Spider Man off that had a sub, it's making me rethink the rest of my lineup..I need bulk pricing..

Yeah subs are amazing bang for the buck. I think it also looks pretty bad ass when you walk up to a pin with a sub underneath it!
