Your next hardware purchase (non guitar)

Been putting together a "small light" live keyboard amp rig. Will report in more detail after a little more fiddling with it.
Wanted something strong enough to do fair level of keybass if necessary. Clean but not abusively loud. Preferably small enough to fit in my 2 door jeep wrangler (I never have the back seats installed).
Actually the "full rig" won't quite fit, but everything should fit the jeep if I leave the two small subwoofers at home. Not all gigs need the subs. For instance if not playing keybass.
It is two 2-way very small vented 15" coax wedge monitors (that will also stand up like PA speakers), supposedly good down to 55 Hz or whatever. And two small 15" ported subs with an F3 of 50 Hz or possibly 40 Hz, specs disagree and I didn't measure it yet.
Two 15's have more surface area than a single 18" and even small 18" cabs are kinda big to tote around for an old guy. Running stereo with four 15" speakers ought to give some good solid clean modest-level keybass and drum machine kick drum, without working too hard.
They are passive speakers, driving them with a crown xls 1502 digital amp, about 300 watts/ch rms into 8 ohms (mids and highs) and a little over 500 watts/ch into 4 ohme below 200 Hz or whatever when the passive lowpass crossover in the little 15" subs kick in. That much cranked full-up would distort the speakers, but odds are low of not having sufficient power for the speakers anyway.
A lot of synth bass tones start rolling off the fundamental down below 60 Hz (for various reasons), even if you play down to the bottom of an 88 where the fundamental freq would be subsonic. Same deal with most electric bass frequency response.
The crown xls amps have optional linkwitz-riley lowpass, highpass and bandpass filters so you can set them up for bi or tri amping without an active crossover or speaker processor box. You can hurt vented speakers driving them too hard below their low-freq F3 tuning point, so I experimentally set the crown to highpass mode (24 dB/oct LR) at 45 Hz. Presumably -6 dB at 45 Hz and about -24 dB at 22.5 Hz.
Then I turned the system up "pretty loud" and played deep bone-rattling acoustic bass patches all the way down into the cellar and it wasn't rattling the woofers even way down there, but still felt pretty solid bass even rolling off at 45 Hz. If I got in a situation that it had to be played obnoxiously loud, could possibly further increase clean performance by further raising the amp's highpass frequency. If it gets so loud that real low notes are rattling the speakers.

whether i purchase anything before that, i don't know?
its all about places having stock
still a few pedals im after and a couple more modules chosen.
also im looking at the koma field kit, looks interesting

A couple of valves, to build a pair of these

I just became happy owner of Make Noise 0-Coast.
Too bad I don't have all necessary cables to connect it

Funny you should say that but I'm just about to order the bits to make something like this:

Found a great deal on a DSI Prophet 6. Now my synth arsenal is complete!! 
Still spending a lot of time on the road, but if I was back in the studio, would be tempted to pick up a Korg 770 or a classic MS-20 if I could find one all cleaned up and in good condition.
Spotted a Moog Sonic Six in a pawn shop the other day, but it looks pretty beat up.
