A high power handling 5¼" driver that offers a truly smooth response and is a good upgrade or replacement for the famous KEF B110 and similar bass/mid speakers Ideal for a modern closed box LS3/5A type speaker project and especially good as a near field monitor Lowest £55.50 delivered UK price on eBay! I do not drop ship or buy product in only after your purchase: every speaker is in stock and each one will also be tested before I despatch it
Thus this driver is a very good candidate for anyone considering a modern take on the famous BBC LS3/5A type of small box speaker as it does not have the 8 Ohm KEF B110's huge 10-12dB resonant peaks at 1.5 & 1.9KHz, the taming of which caused so much trouble with all the crossover designs that used it, (needing special electrical damping networks and a loss of efficiency and sound clarity - the improved 6 Ohm B110C/SP2128 for the later LS3/5A versions was quality controlled, tested and matched in pairs by KEF, so is better, but it still had a 6dB hump in it's response!) Designs based upon this modern driver will have reduced harmonic distortion because of: Closed box enclosures as small as only 10 litres can be used.

141.3mm) so please check your original driver's hole spacing for compatability before
purchasing. BUYER'S NOTE: Please wait for your eBay invoice to arrive before paying, to avoid errors and delay in despatch SHIPPING COSTS: For two or more I can get two into a box sized 31x12x24 weighing 3.5Kg or four into one 32x25x24 weighing 7Kg and as an example, sent insured and tracked and signed for via the Post Office to Australia would cost £82.30 or £102.00 respectively, which is less via Fedex, the lowest cost courier to OZ at £60.70 or £76.00 respectively. For an estimate of the cost of shipping to other destinations please advise your full postal address and the quantity of drivers required. NB: These shipping costs details apply to this eBay listing ONLY and are subject to variance as postal or shipping costs can change without notice and any increases will be passed on!
NB: The business has now been trading over 25 years as a trade B2B UK and exporting wholesale supplier and high power electronics design consultancy, so VAT is always extra, where it is applicable, (see below). It seems that eBay does not properly understand the UK VAT rules governing domestic and International sales and exports, so I have consulted HM Revenue & Customs on this to obtain detailed clarification, and must always follow their clear advice, which is as follows: For all eBay auction winners outside of the EU - these are not liable to pay the UK VAT, but will still receive a detailed invoice (without any added VAT); please contact me before paying! For all eBay Fixed Price offer buyers in the UK or EU member states - I will go along with eBay's silly rules and show prices that include the VAT at the current UK rate of 20% in the purchase price shown and in the shipping costs and will issue a full, detailed VAT invoice on the day of despatch of the item(s). For all eBay Fixed Price offer buyers outside of the EU - these are not liable to pay the UK VAT, but will still receive a detailed invoice (without any added VAT). All overseas bidders must satisfy themselves of the international shipping cost of an item before bidding by checking either To protect both parties in the transaction, I insist that both the name and the address registered with eBay and that registered with PayPal must be the same, so please confirm your delivery address via eBay message when you receive your invoice from me to ensure it is correct and verifiable or I will delay shipping of your item; I also need a land line telephone number as all of the courier’s booking systems now require this and it will also help the delivery driver at your door, in case of non-answer, if you can also provide a mobile number as well. Also, please be advised that this item will only be despatched via an insured and signed for method, to addresses which are exactly the same in both eBay and PayPal; I will not send items to a different address, a Post Office box, or care of an unverified business address, (see the above). I accept PayPal payments or cash if collecting in person, but if the winning bidder wishes to pay via a cheque or by postal order(s) or by a bank transfer then under EU law I legally must accept this, (whatever eBay says), but because of recent problems, my bank has advised me that UK cheques and postal orders still cannot be regarded as having cleared until at least 10 working days have elapsed since the date I present them over the bank counter, (for a bank transfer this becomes 8 working days for UK transfers and 16 working days for International transfers and cheques drawn on foreign banks). Items paid for by cheque, postal order(s) or transfer will thus be sent out on the next available working day following this waiting period, provided the remittance still shows as "cleared funds". I do not accept wired cash transfers, or respond to attempts to launder money and all such approaches will be immediately reported. MONACOR SPH-135KEP I now reserve the right to cancel your bid and block you if you have zero or very low/bad feedback; if you are in this situation, you must provide me with your full details by e-mail prior to bidding to avoid this action, (from now on, due to fraudsters, I will cancel any sale to such a member and this includes last second winning bidders - please ask for permission to bid first!!) Items are checked and tested before despatch wherever possible and nearly always double box packed with outer energy absorbing packing to minimise the possibility of damage in transit; I use recycled materials if I can and pack as lightly as practical for item protection as part of my contribution towards minimising global warming as more weight in transit uses more fuel. I add no packing or handling charges! |
