The important thing is that it does what you need, and your happy with it.

Good luck with the build Bob. If you can take some pics thru the building process.

Again good luck. BOOM! BOOM! BOOM!

Just ordered the LSA900

My plan to take over the world is almost complete.

900 wrms and 2 x 15s in HWK...........crazy

Yes, I will take pictures. Little old school in the shutterbug area. Will have to have them developed, then scan them. Not sure how they will turn out.

Crazy,......me.........ok.

I have better sidekick than "The Brain"......I have you guys.

Will be waiting for the mail every day. I'll let you know what the LSA900 looks like when it comes. Hopefully hasn't been run over by a truck. Fellow that emailed me back assured me it was 'new' and perfectly fine. (Then why so cheap?)

I'll buy that..........pun intended.

Agreed.  The 150 Hz lowpass integral to the amp is not low enough for a clean subwoofer... granted, the HWK is a bandpass box, so much of that higher frequency content will be attenuated in the cabinet, but the woofers will still be producing it and hence wasting energy.  Unless your source has a sub out which is passed lower, you will need some sort of crossover to lowpass at about 80 Hz or so.  If you have the sub out, you're good to go, and (as far as I can tell from the photographs) need only use a splitter as J_Rock suggested.  If not, you need either:

1) An active crossover, which will filter frequencies prior to the amplifier, or

2) A passive crossover, which filters after amplification, and hence wastes power.  This is the cheaper option, so you might want to do this for now and then swap out to an active crossover later.

I would use balanced XLR inputs wherever you can, instead of RCA or 1/4" jacks (you will need appropriate cables), and Neutrik speakon connectors for the amp output and HW input connections.  No need to buy expensive pro audio cables - just buy the connectors and make your own.

i connected my pa amp to the headphone out on my integrated amp, using a y-splitter so that i have 2 XLR jacks going in the x-over.
i am terribly sorry i didn't buy parts for the cables instead of buying the whole cable : 20$ for 2*1m xlr-jack cables and 2*1m xlr-xlr cables. i'm not sure if it would have been cheeper if i would have built my own.
i have my dbs crossed at about 65, because i hate how the db-10 boosts the 100-120hz section.

i just remembered...taxis in romania use XLR for powering the "advertisment" on the top. i laughed when i first saw that (2 days after i've bought my cables)
