UK: AE(Stryke) AV15 mk2 & BK 500w Panel Amp

[ShinOBIWAN]

15" Acoustic Elegance (aka Stryke) AV15 mk2

Bought around 2 months ago from Marshall Chong Audio: http://www.mcaudio.co.uk/audio-bass.htm

This driver is completely in as new condition. It has never been installed in cabinet and only tested very briefly to ensure it was in working order on arrival from MC Audio, so this hasn't been run in at all.

Nearly 2"(46mm) peak-to-peak excursion with a 15" radiating area means lots of displacement for deep bass.

The sub has been stored in its original and hefty packing box for complete protection, this will also ensure that it will withstand even a vicious beating from the postman should such a thing happen.

I've never heard it running but from the accounts spread around the net, its an extremely nice sub for the money and I'm offering this perfect example at a fraction of the RRP.

Please note that this is dual 4ohm voice coil driver, so wired in parallel means an 8ohm load and series is 2ohm.

Qts: 0.471
Qms: 5.293
Qes: 0.517
Vas: 140.1 ltrs
Fs: 22.39 Hz
Xmax: 24 mm
Sd: 830 cm2
Sensitivity: 91dB (1w/1m)

Also includes TS spec sheet with the driver.

Paid £189 asking for £120 + postage






BK Electronics BSBPV 500 Subwoofer Panel Amp

A perfect companion to the AV15 above

Again this is completely as new, never installed in a cabinet but has been tested and works perfectly.

Offers virtually all connectivity options with speaker level, stereo RCA's and XLR balanced inputs. Fully discrete level controls for both high and low level inputs so its perfectly feasible to have two different setups for music and movies. As well as this, the amp comes with fullly variable phase control and a 40-120hz 4th order low pass filter, interestingly this filter can also defeated to allow for full range reproduction (the amp could be used to drive a loudspeaker). Airtight construction means that you don't have to build a seperate chamber within the enclosure, should you wish.

The amp itself uses lateral MOSFET devices typical used in full range amps rather than lesser devices. This ensures that the amp sounds very good indeed, possibly an audiophile subwoofer amp? There's also an EQ section and infrasonic highpass filter which can be set for a 6dB boost at 15hz-30hz, all this can also be bypassed for a flat response. The manual details how to set these options.

Excellently specified:

• Phase Shift Continuously variable 0 - 180Deg
• 500W R.M.S. Into 4 Ohms
• High and Low level inputs with separate gain controls
• Balanced Input
• Upper roll off is continuously variable between 40Hz and 120Hz
• Filter Bypass switch, for use with sub outs from processors
• +6dB Eq selectable at 15,20,25 and 30Hz can be by-passed for flat response to -3dB at 3Hz
• Airtight construction
• 5 Second Anti Thump Delay
• Thermal Protection
• ASP Automatic Speaker Protection
• Short Circuit Protection
• 4mm Thick Aluminium Front Panel
• Complete with Mains, High Level and Low Level Leads

See here for further details: http://www.bkelec.com/MODULES/bsbpv500.htm

Ships in its own wooden crate for complete safety and will ensure it arrives in good order. Comes with highlevel and low level cables, power cord, manual and all screws.

Paid £220, asking £150 + postage






BTW: If anyone wants both of these items together, I will offer a further saving of £20 making the total £250 for both. That is very cheap for the performance on offer here.

And I so was looking forward to teaching you electronics over the internet...

Al, its still on.

I've decided to use my 15" Volt Radials that I was saving for a future project I've just got to figure out how I can get good performance from reasonably sized boxes.

BK panel amp is now sold to Steve.

AV15mk2 reduced to £110 + postage. If I don't get any interest at this price I'll see if it does OK on ebay.

AV15 held, pending payment, for Vikash.

I've tried a few enclosure designs for my 15" volts [small 60 litre sealed, medium 120 litre ported and large 220 litre ported].

The large ported was by far the best.

What are you planning?

I haven't even began to consider that just yet. Its likely that I'll be without subs for quite sometime because I simply have no time these days for DIY. I regrettably had to flog on my collection of projects recently (the AV15 being one of them) for this very reason.

In the end I may just go with a couple of commercial subs to make my life easier. I'll see how it goes but hopefully I don't have to sell the Volt Radials and something good will come of them.

I did wonder why the big clearout. I have had to rationalise slightly myself recently and am now considering a clearout as well. Too many parts kept as 'one day that will be a good project'.

If you are considering buying maybe we can come to a good arrangement on one of our 8 Ball Audio subs

Yep, the important stuff always seems to get put on hold while you we about the daily routines; job, socialising, cost of living etc. It sucks sometimes, its a shame we have to sleep otherwise I could put that time to good use

Please don't list your stuff otherwise its likely I'll just end up with yet more neverending projects

Thanks for the nod on the sub but have no money for hifi just at the minute. I've bought a whole raft of new room treatments that should lend a more asthetic look rather than the industrial wedges I was using before - and yes, this is yet another project
