Re: Sealed test enclosure

More progress is being made. I'll post some pics up tonight. I've got the baffles and backs done and mounted up. I'll be putting a 1/2" roundover on the cabs tonight. From there I have to seal up the inside, install the weatherstripping, install lining, put the handles on, install the speakons and figure out what I'm going to do for bracing the back panel. It must be removable to match the back panel. I've got an idea but until I actually try it... After all of that gets done it'll be time to start on the second pair of cabs. I should get done with those about this time next year. At this point I've got about 5years worth of projects I want to do.

Re: Sealed test enclosure

Looking good! What subs are you planning on trying out?

Re: Sealed test enclosure

These are going to end up housing XXX 18's long term. One sealed in each enclosure. A total of 4 of em powered off of 2 QSC PL9.0's. It should be about 3250w per driver. My 220v 50A line for those is being run on Friday. I've had all of the drivers and the 2 amps for almost a year now. It'll probably take me another year to get the whole thing up and running.

However I plan on using these to do some port, stuffing, lining, bracing, dual opposed and driver tests as well. I should be able to clear up to a 21" driver past the baffle mounting bolts. A 22" may take some ingenuity if I ever wanted to do that. 9 cu ft net should be enough space to test most 15-21" drivers sealed, or most 12-15's ported.

Re: Sealed test enclosure

Yep standard 2x2 which is actually more like 1.5 x 1.5.

Re: Sealed test enclosure

Further progress. The first 2 enclosures are done and I've started on the second set. They should go a lot quicker because I know what I'm doing this time. I ended up using roll on Duplicolor truck bed liner on them. I tried to use the spray on stuff but it just wasn't working and would've cost a fortune. I've also got the 220v lines for the amplifiers installed.

Re: Sealed test enclosure

The cabinets are looking good and those XXX's always look impressive. Teaching the little guy from a young age, eh?

Re: Sealed test enclosure

What's so special about the XXX 18 besides the 54mm Xmax, high power handling, and the 15.60hz resonance frequency? Does it have really low distortion like the LMS 18's? I just don't really see why it's worth $1500+ at some places. Is it really that good?

By the way, nice looking boxes. Looking foward to some results

Re: Sealed test enclosure

You sort of answered your own question Dylan. Ruggedness, power handling, low end extension without EQ, low distortion, uncompressed deep bass dynamics, etc. I got mine for $700-$850.
