Yup, prime example of a very low budget "high power" amp and lack of system calibration. Needless to say he is looking to get a better amp to drive a single SPL-15. m

Pretty good!

You can go with 0.7 cubes (net) with a 3 inch port 12 inches long. This should tune it to about 45Hz. Good luck! Best, Mark

Get two of them. Then you will have dual 4's

Precisely. So, if you want to do a 3 cube net enclosure, make it 4 cubes gross volume. If you like the dimensional look of the test box I put together, the inside dimensions are 27"L x 16"H x 16"D. You can tune a bit higher - say 30Hz for that added bump if its going in an auto. For this, your port is 2.5" x 16" x 35" long.

Ok, give me a bit of time and I'll come up with some.

Man, you're lucky. Make sure to skip over the border in Belgium and have a Flanders' special....

Sorry, it is only available in single 4 Ohm configs.

Good luck, and fill us in on your progress.

Hmmm... Certainly a tough call, since I do not know much (nothing) about the Type R except all the raves from the volume guys. The recommended box sizes are a guideline for folks to get started. You seem to have a fairly high tuning, so if the MAW was doing well for you, the IXL will do better (it will peak higher resulting in more output with the same power applied). Not sure if you caught this but a guy is selling a brand new IXL-15 on ca.com - you might want to check it out... m

Ok, I can see how that would be a potential problem. Can you afford vertical space? Reason I ask is you can go with a box with a "small" footprint but tall. For example, if you can do up a box with internal dimensions of say, 10" x 19" x 70" high you achieve nearly 8 cubes in gross volume. You can then mount the driver on the front and the port at the bottom or top of the cabinet - or front/back with an elbow if you go with tubes. This will allow you to achieve a lower tuning and help to bring in the ultra low end you would desire for HT.

Ok, what you will want to do (if you can) is to build big and tune low, so you can get the subsonics that are present in movies these days. If you look at the EBS suggestion, this will put you in that area. If you want to go with a simple and easy build, snag yourself 20" and 8" Sonotubes. You can bang together a sub in less than a day. Best, Mark

Is this for home or car audio?

Well, good for you! You gotta like it when businesses screw up like that sometimes. Too bad about the girl tho...

Yup, in the virtual flesh...

The IXL-18 is a big box driver. I suggest using 4.6 cubes for sealed. This configuration results in an overall Q of about 0.65. Ported, about 7 cubes, and since you're playing music only, tune to 30Hz. If your intent is to have the option to add on later, a sealed configuration would be a good start. You can always change if you feel you need more output. Best, Mark

Yeah, my holiday from the holiday is called 'work'.

They better give you something for all the hassle - free tank of gas, a few bucks off... was the salesperson cute?

Hi there, Your question is pretty open-ended. I don't think anyone can provide you with an accurate answer given the fact that all setups are installation dependent. The general rule is more cone area rules over less, with all things being equal. So, if your intent was to build a 6 cube box for example, having two MJ's in there would probably be slightly louder than a singe IXL. On the flip side, I have heard from others that given the same size box, a single driver in a ported box could be louder than two in a sealed enclosure. Perhaps if you provide a bit more info, folks may be able to respond better... Best, Mark

Yeah, hurry up

Interesting. The IXL-18 has done very well with the home audio/home theater crowd. Not many use it in car audio due to the fact that it simple requires such a large box to operate. There's a gent from Oz who did a build using two IXL-18's recently. Perhaps check a page or two back for his thread...

Hi there, I'm not sure if anyone can answer this due to the fact that there aren't many IXL's out there yet. Best, Mark

That's quite the stack Arthur...

Back.... thank goodness. I'm glad "holidays" only come one a year

Yup, a good box size for this unit would be 1.7 - 2 cubes. Tune it 33-35Hz... m
